Ask HN: What is the best income stream you have created till date?

399 pointsby debanjan16over 2 years ago
It may be passive or active or maintenance mode of income. Just something created by you and your sole passion that have worked out for quite some time and maybe still going on.

Probably not relevant to the younger set here on HN: I became obsessed in the late 90’s with using a camera to photograph subjects and events that are hard to observe with the naked eye. (Examples include: spotted bats photographed in flight, or red tree voles that only live at the tippy top of Doug fir trees, or nocturnal genets photographed in arboreal habitats). I loved the challenge of the work.<p>I grew up poor. So I had to figure out how to finance this work up front. It was a true obsession and I would have probably gone completely broke if not for the fantastic interest my work generated. I was licensing the work for good $$$.<p>Cut to now: I’m still fascinated with this type of photography. But my work these days involves social media content generation. Since I hate being the center of attention, I’m lucky that my clients just want content (and leave me out!).<p>But this early work just keeps selling. The subjects were so difficult to capture that I guess others have not really pursued the same path? I’m probably just a lucky fool.<p>If I were to die tomorrow, my family would still have good income from just this early work. I just can’t believe how this played out for me. I’d like to think it was a clever strategy. But no.<p>Coming from a family riven with poverty, addiction, and early death - I’m just astounded. I’ve already outlived every male member of my family in the last three generations. I hope to set my child on a different path thanks to this lucky break of timing + opportunity.

<a href="https:&#x2F;&#x2F;www.newaudiotechnology.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.newaudiotechnology.com&#x2F;</a><p>A shared friend introduced me to someone who claimed to be a struggling Hollywood genius. We were all drinking at some university party. He told us about all the cool shit he would do if only technology wasn&#x27;t so bad. So I built a tool to solve his issues. To my surprise, he used it on the Expendables 3 blurays. Later, the audio crew for George Lukas&#x27; Red Tails praised the tool in an interview. Hollywood guy got grammy nominated. I got paid first for development and then licensing fees. But I mostly like it not for the financials, but because this way my software made it onto a few magazine covers :) I collected all of them.

I had partnering with a marketing agency for awhile doing implementation of their designs in WordPress. After a few years of clients breaking their sites doing upgrades and other ad-hoc questions&#x2F;enhancement requests coming via email, I got tired of sending $100-200 invoices, so I started selling &quot;WordPress Maintenance&quot; as a product. It&#x27;s not fun or sexy, but don&#x27;t underestimate the number of organizations willing to pay $3K&#x2F;year to be able to email you for advice, install plugins, add custom post types, and keep things up to date. I&#x27;ve got ~12 clients now (started with 4 in 2017) and it&#x27;s an &quot;easy&quot; $30K every year.<p>FWIW, I work exclusively with <i>local</i> clients. Local clients, in my experience, are more willing to pay more to local people.

Suing lawyers as side income. we all know most lawyers are scummy using all sorts of deceit to gain advantage. However in the increasing documented world, it is a matter of digging(using text search) to find fault with the offending lawyer&#x27;s deceit and then file a DIY action in court.<p>I am involved in estate litigation since 2016 where I discovered collusion by many lawyers with the estate administrator to defraud the estate. Our laws for anti corruption are stringent in my country where a lawyer causing a beneficiary damage as the estate&#x27;s lawyer is liable for 20 yrs imprisonment and 5x penalty fine for the gratification received.

I actually have a few:<p>1) Board member (advisor really) of a crypto&#x2F;blockchain company. They pay me $5k per month to basically answer questions and help solve certain issues that might arise. There&#x27;s also regular meetings but all in I spend 4 hours per week max.<p>2) Small contractor jobs. I was a contractor and home builder in a previous life. These days, I do side jobs both for the extra income and as a way to relax from my regular tech job. I build decks, sheds, small patios, and some indoor remodeling stuff. All of it is really basic because I have no interest in large jobs that would take a lot of time. A 10x12 shed will net me around $6k and I can build it in a weekend. A similar sized deck I&#x27;ll charge $25k. Small patio pours I&#x27;ll net $4k. During Christmas season (right now) I also hang lights. I&#x27;ll charge between $1500 - $2500 and net most of that. Takes me around an hour for a normal two story house.<p>3) Tech consultant. I help administer various Wordpress and other sites for clients. Basic stuff like plugins, changing font, layouts, etc. Super easy and I get paid a monthly retainer.<p>4) I work two six-figure engineering jobs. Neither is super difficult which gives me time to do the other things and still have free-time to spend with my family, friends, and hobbies.<p>5) Rental income. I built a few single family homes and apartment buildings (12 units per building). Nets very good income but can also be demanding because I prefer to do most of the management work myself. Just sold one 12-plex for $1.6MM in August and am sitting on the others.

My favorite so far was a company I founded about 20 years ago with a friend who worked in the film sound industry. He had an idea for a hyper-niche tool for automatically syncing changes from video to sound (industry term is &quot;conforming&quot;). He&#x27;d approached a couple people&#x2F;companies he knew that made tools in adjacent spaces but got turned down with &quot;that&#x27;s impossible&quot; or &quot;it&#x27;s not worth it&quot;. I had no experience in the space but I got intrigued just from a &quot;can it be done&quot; perspective and coded it up. Once written it required very little maintenance, it was just available on our website for download and we used a shareware service to deal with licensing and sales. Only marketing was word of mouth. Every time someone bought a copy the shareware service would send a text, so I set the text alert sound for their number to be the cash register sound. It was a small addressable market so didn&#x27;t sell all that often but it was always a little dopamine boost to hear the &quot;ka-ching&quot; come out of my phone. Most sales only netted me a couple hundred bucks, but every once in a while a big player (like a movie studio) would pick up a bunch of copies at once. Eventually sold it off to a competitor and collected a small royalty stream for another few years.

When I was in college I sold discarded text books on half.com. This isn’t my best income stream, but in many ways it was my favorite.<p>After the Spring 2000 semester, I noticed that the bookstores had junk book bins. Students would dump into the bins any books that the bookstore would not buy back. Anyone was welcome to rummage through the bin and if they found something interesting they could keep it.<p>The bookstores wouldn’t buy books back if they knew that a new version had been released. They of course wanted to avoid being stuck with useless inventory. I wondered if these books had residual value elsewhere. I collected a few and took them home and started looking up them up on half.com. Sure enough, all of them had listings and lots of them were listed for 10’s of dollars!<p>For the next few days I made a continuous circuit around all the bookstores, loading my car with any books I found in the bins, and dumping them in my living room. At night I would list the day’s haul. Because my inventory was free, I always listed $1 lower than the cheapest listing.<p>I now had an inventory of several thousand books and a very irritated set of roommates, including my future wife. All I had to do was sit back and wait for classes to start somewhere in the world where one of these books might still be in use.<p>Within a week orders started to roll in. Soon I was heading to the post office daily with a huge load of books. Things would quiet down whenever a there was a lull in sessions starting. I’d replenish inventory as the various summer sessions completed.<p>Fall semester generated a huge bump sales and I was able to get a huge inventory of books when the semester ended. Unfortunately that proved to be the last semester of junk book bins. The stores got wise to what the kid in the beat up Honda was up to and started collecting the junk books for themselves.<p>I continued to sell what books I had and that went on for the rest of the time I was in school. After graduation my wife demanded that I chuck the rest. She’d had enough of random stacks of old textbooks.

I&#x27;m a mechanical engineer (satellites currently, launch vehicles and satellite payloads previously).<p>On the side I sell budget star tracking astrophotography mounts I designed and build in my basement. I also do a few consulting gigs each year. These efforts combined bring in an extra ~25k annually. My plan is to develop two more space-related products, hire a tech, and transition to more of an oversight and design role rather than the one guy running the whole thing.<p>For the record I don&#x27;t think most people should do this, it is not a balanced life to work this much, generally speaking. But for me it&#x27;s a worthy discomfort to relieve financial pressures from student debt and being the only breadwinner of a young family. Plus it&#x27;s fun stuff, I get to design cool products which is what I do for fun anyway, I just usually stop at the level of prototype when it&#x27;s just for me. ;)

Built a hobby informational web app back in 2005 related to a collectible item I was interested in. It basically tells you if your X is considered common or rare (potentially valuable). Determining that is nuanced and people don&#x27;t want to figure stuff out on their own, so my web app became popular.<p>At this point it has earned over $400k USD lifetime with 75% of that being in the last two years. 100% Adsense. The audience who find&#x2F;use my site are good candidates for high-dollar ads, which is why it has done so well. New data (a few rows in a table) needs to be added once every few months, but it takes &lt; 1hr. Realistically I should invest in blog&#x2F;content but I don&#x27;t really find it interesting any more.<p>Following the &quot;make niche complicated data easily parsable&quot; concept I built another web app in 2018 for a different hobby. For example if the hobby was &quot;phones&quot; and the physical dimensions&#x2F;specs of &quot;phones&quot; was very important to choosing it, my web app would let you visually compare any two &quot;phones&quot; side-by-side at the correct dimensional scale.<p>It apparently solved a problem and traffic grew organically. After years of work this web app should get close to 6 figures annually in 2023 - earned via affiliate sales of &quot;phones&quot; and accessories. It&#x27;s is a much more active endeavor, but if I walked away for 6 months I bet revenue would stay near flat. It fills my time and I find it interesting.<p>I&#x27;m working on web app #3 now which is tangentially related to the &quot;phones&quot; concept.

Wrote a book, published nine years ago.<p>I earned back my advance after about five years and have been receiving royalty checks ever since.<p>This year, it surpassed 100,000 copies sold.<p>Just a little note for other would-be authors ... it&#x27;s never been easier to self-publish -- but getting a book deal with a traditional publisher still has substantial upsides, particularly on the distribution side. There are exceptions (e.g. if you expect digital versions to constitute the vast majority of sales). But by and large, you&#x27;re better off getting a book deal if you can.

My partner and I created a very successful business in the UK out of selling mushroom grow kits and microscopy spores.<p>We didn’t think there would be any market here because there weren’t any UK shops doing it. Then a couple of years later it took off and growing mushrooms became cool.<p>In this time we learned how to run a webshop and navigate an industry where every payment processor dropped us - to the point where we only accept cash, bank transfer and crypto.<p>Our Woocommerce shop was built on pure passion for mushrooms and a crazy late night idea. The kinds you usually just leave as an idea. Now it has consumed our lives and we have multiple employees.<p>Our business continues to grow with recent months bringing in around £60K&#x2F;month in revenue.<p>I had never known what it was like going to a supermarket and not having to add the cost of everything in my head. But with the money, I learned the most valuable lesson - it could all go tomorrow and I would be totally fine with it.

Left my job in 2014. Tried a few things that didn&#x27;t succeed before selling programming ebooks came to my rescue (2018). From the danger of draining out my savings completely, I&#x27;m now earning more than double my needs (which isn&#x27;t really that much for my modest lifestyle, living alone in a developing nation - $150&#x2F;month).<p>What&#x27;s more, my ebooks are all free to read online. Only PDF&#x2F;EPUB are sold, and I&#x27;ve always given them away for free during launch week.<p>List of my ebooks: <a href="https:&#x2F;&#x2F;learnbyexample.github.io&#x2F;books&#x2F;" rel="nofollow">https:&#x2F;&#x2F;learnbyexample.github.io&#x2F;books&#x2F;</a> (topics include Regular Expressions, Linux CLI tools, Python and Vim)

It’s definitely not my passion but in 2013 I built a WordPress plugin around the API of a popular newsletter service and it’s been paying my bills ever since.<p>Still going strong at €36K per month excluding VAT.<p>There was (and still is) a huge market where non-technical people are looking for a GUI around something a programmer would find very simple (and usually too boring to work on). More so if the tech surrounding it is not particularly sexy, as is the case for WordPress and PHP.<p>Ps. In case anyone is reading this, I am open to selling. I spent about 4 hours a week on it and the rest is handled by 2 freelance people costing about €1K &#x2F; month each. Contact me for details if interested and willing to pay in the ballpark of €1.6M.

My cofounder and I have bootstrapped two software products that are generating revenue today with minimal involvement on our side.<p>The first product is a B2B onboarding platform. This product generates approx. $100k&#x2F;year.<p>Our second product is a microsaas that turns google drive folders into a hosted, searchable wiki with one click. This product is making $2k&#x2F;month.<p>Both products require minimum support and continue to sustain themselves.<p>One thing to note is that we did work full time on both of these products for like 1.5 years during the pandemic. At the time, it was definitely not the best income stream we had created but became so after we both got &quot;real&quot; jobs again.

Software consulting. You’d be surprised how many little businesses out there have a need for custom software. I make about $60-70k&#x2F;year in my spare time (maybe 10 hours&#x2F;week) doing everything from adding features to legacy products, building brand new applications and even simply conducting technical interviews. It’s also pretty nice to work on something besides the usual thing at work, experiment with new&#x2F;different tech and also get paid handsomely for it.

My fiancee sells self-made art somewhat successfully for the last 9 months. I contribute by managing communication with buyers through FB Marketplace, Craigslist, and while we tried Etsy, it didn&#x27;t do that well. We specifically target the mid-range market which means we price below top artists on Etsy&#x2F;Instagram, but above cheap prints and generic Ikea style art.<p>It definitely requires a lot of physical work on her part and our spare bedroom is basically a pile of canvas, paint, plaster, and other supplies, but it has generated over $10,000 in revenue. We could optimize more and she could make prints of some of her better paintings, but she does it for fun and most of the money she uses for shopping (and I spend my share on triathlon gear!)

To date the best one i created was a specialized billing&#x2F;inventory system for an injectable class of mental health drugs for community clinics in Mississippi. I did it on the side while fully employed (heh the advantages of youth and no family). Mississippi&#x27;s medicaid system couldn&#x27;t handle the coding and so it was paper and it took forever for pharmacies to be reimbursed and so no pharmacy would dispense the drugs. I developed it with a pharmacist friend of mine (former boss) who took on the expensive risk of stocking the drugs and then he paid me probably $75k over about a year to work on it with him. It made him a lot of money and when he eventually sold his pharmacy he wrote me a check for $50k. I have the email i sent to him announcing the system was live framed and hung on my wall.<p>i was pretty naive then, i wish i could do the whole thing over.

Exercising options in a startup that I was <i>convinced</i> wasn&#x27;t going anywhere but had great tech, and would be a decent acquisition within a year or two.<p>Turns out, they shook off both their doldrums and their VC-fueled overambition and started <i>throwing off</i> cash.

Back in my studies a class mate asked to help him with coding assignment. I did and got 10 units of local money. Then another friend asked the same. The word started to spread, prices increased and algorithmic coding assignments become my source of income. After couple of years I have had all more than a half of assignments solved which were given by lecturers from 1st to 3rd years of studies. If anybody contacted me, there was a high chance I have already solved exactly that problem and simply needed just copy the code and collect money. It was a good life since I really enjoyed solving those tasks.<p>That was a shady thing - I literally helped to cheat the system. But these were times in our market.<p>Despite that this &quot;job&quot; lasted for couple of years only, the best income was that it pushed my coding experience years ahead compared to my peers. I was way more better than most of them. At least at coding :-)

I built a social media analytics API. At its peak, it brought in about $23k&#x2F;mo, with server costs at about $3k&#x2F;mo. When I got a job at Instagram, they decided it was a conflict of interest and told me to sell it, which I did for a very healthy six figure sum.

I pay myself 70k p.a. and reinvest the rest into the company. it is growing around 100% in revenue each year. in the beginning I asked myself whether it&#x27;s worth it not to just develop for a big company, but now it pays. I don&#x27;t even have to work the full 8 hours a day.

Surprised how few of these answers involve automating revenue, mostly selling continued labor<p>Currently the best I&#x27;ve made is from iOS apps with little to no server backend, or async server-sync&#x27;d offline-first local DBs tolerant of downtime to minimize on-call requirements. I make money through recurring IAP, and offer student etc. discounted rates without any verification to capture more sales. These apps grow organically when I don&#x27;t put time into them actively.

I&#x27;ve had quite a few:<p>1. Selling domain names. This was when I was in college and somehow traded my way into mid-high five-figure domain names. I turned over $100k in profits in a year, and then 2008 happened and all markets collapsed.<p>2. Starting a D2C brand. Shipping is automated via a third-party provider. Sourcing is easy since I have a very reliable supplier. All marketing is through word of mouth. I get around 300 orders on Amazon monthly, some 100 on our website, and land the occassional business order that gets me around 2,000 orders extra per year. Not a huge money maker, but pays my mortgage for practically 2-3 hours of work&#x2F;month.<p>3. I ran an informational website about music production (I produce as a hobby). Somehow, a few of my articles became popular and I landed a ton of good links. Google loved my website and I was pulling in mid four-figures in affiliate checks every month. That went on for years even when I stopped working on the site.

Not my highest paying role but I write material related to Computer Science. I&#x27;ve written chapters of books, online revision material, online CPD courses etc. So far it is all related to Computer Science education - the books are school textbooks, some CPD is aimed at trainee (or pre-trainee) teachers, whilst other bits are aimed at existing teachers to help upskill them. Most of the work is for well known publishers&#x2F;training providers etc on a freelance basis.<p>I enjoy the work. I&#x27;d love to start writing&#x2F;creating CPD etc for other audiences but need to figure out how.

I built a web-based game that integrated into a popular MMO. The game was free to play but I monetized through an affiliate agreement with the MMO company.<p>Eventually they realized they could just copy the game and run it inside the MMO itself, so they terminated the partnership. At the end it was grossing 20k&#x2F;month, but it literally consumed every moment of my free time so in some ways it was a relief to shut it down.<p>This was early in my career so I learned an incredible amount about scaling, catching, etc. that I was able to leverage at future jobs.

I sell public domain art prints on Etsy.<p>Haven’t done anything on it beyond fulfilling orders for years - I found a really high-quality printers who do the production and shipping - but it’s probably good for an extra £100-300 a month, depending on how Etsy’s algorithm is feeling at the time.<p>I could probably sell more if I put more effort into it, but it’s nice as a very low-effort, if small, income stream.

Passive investing with savings from my tech job. My wife and I earned around 150k per year for 10-12 years but lived happily off of 40-60k per year for that time. The difference went into savings and retirement accounts and now we live off that nest egg and do what we want. I started a business teaching whitewater kayaking, packrafting, and swiftwater rescue which really took off during COVID but honestly the nest egg is what allowed me to do it pretty risk free.

None of my “passion projects” have paid nearly as well as my $dayjob’s IPO. Went from highly in debt to multi-millionaire over the course of about 6 hours one day last year.<p>I published a few smutty short stories and a couple of apps that I’d made for my kids, all of which together might have netted me a few thousand in total. No marketing or anything.

The easiest money I ever made was doing affiliate marketing for a domain name registrar. They would pay you $20 every time someone signed up for their free domain name promotion. I just posted on &#x2F;r&#x2F;freebies every week for two months. Made a few thousand dollars until the registrar realized how much they were overpaying the affiliate marketers, and they stopped doing the free domain name promotion.

macOS apps which I share at <a href="https:&#x2F;&#x2F;lowtechguys.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;lowtechguys.com&#x2F;</a> bring me $7k&#x2F;month on average at the moment, and it keeps growing.<p>It started in 2017 when I shared the first free and open source version of Lunar (<a href="https:&#x2F;&#x2F;lunar.fyi&#x2F;" rel="nofollow">https:&#x2F;&#x2F;lunar.fyi&#x2F;</a>), an app for controlling monitors.<p>At that time, there was only a command line for doing this stuff (<a href="https:&#x2F;&#x2F;github.com&#x2F;kfix&#x2F;ddcctl" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;kfix&#x2F;ddcctl</a>) and I wanted a more visual way of changing the brightness. So I learned Swift, learned how to bridge the ddcctl C code and call it from Swift, then made a rough interface and published it: <a href="https:&#x2F;&#x2F;www.producthunt.com&#x2F;products&#x2F;lunar#lunar-5" rel="nofollow">https:&#x2F;&#x2F;www.producthunt.com&#x2F;products&#x2F;lunar#lunar-5</a><p>It turned out people did have a need for this and asked if they could donate. I set up a <i>Buy me a Coffee</i> page and in 4 years collected about $5k in donations. That&#x27;s a lot of money for a Romanian.<p>When Apple Silicon appeared, Lunar didn&#x27;t work anymore because the whole hardware arrangement and drivers were different, and there was no documentation on how to send I²C data. I took the plunge and quit my stressful job, bought an M1 MacBook and reverse engineered the I²C communication: <a href="https:&#x2F;&#x2F;alinpanaitiu.com&#x2F;blog&#x2F;journey-to-ddc-on-m1-macs&#x2F;" rel="nofollow">https:&#x2F;&#x2F;alinpanaitiu.com&#x2F;blog&#x2F;journey-to-ddc-on-m1-macs&#x2F;</a><p>Then published Lunar 4 as a Free version with a Pro paid upgrade. I was reluctant with this, didn&#x27;t think anyone would buy it, but to this day I&#x27;m able to be unemployed and put my ideas into practice because of it.

I spent last month trying as many things as possible to see what was most desirable. Best paying ended up being trading time for money. In order of most money made:<p>• workshops • custom illustration packs • microcoaching • online courses • ebooks • merch on Etsy • Upwork gig<p>I’ll be working on converting residue from time-for-money projects into products. For example, I’m turning my workshops into online courses, my illustration packs into icon bundles to sell as digital products, microcoaching as asynch videos, online courses transcribed into ebooks, and concepts from all of them into merch (coffee mugs, journals, t-shirts) with an ability to mix and match bundles<p>I started all of this when I got laid off. I ended up needing flexibility to take time off to help my family so can’t see getting a full time job anytime soon. I’m also done working 60-80 hour weeks for startups and can’t figure out a job that pays enough that’s low stress. So scrambling to make this work

To make a long story short … I built a delivery service that unexpectedly went semi-viral. Within a matter of hours we went from 2-5 orders per day, to 10, 20, 30, 40 … I had a small crew, and it got to the point where I was ordering Ubers and handing the drivers wads of cash to make the deliveries. Somehow we managed, and I eventually shut the service down to pursue a more interesting opportunity. It was a wild ride, and I learned more about business in those 2 short months than the 10 years prior.

My PhD was in image processing - never really got to use it in any day job, but I published an iPhone app that back in the day that would read a sudoku puzzle and solve it. That led to a few side gigs and I’ve done off and on consulting jobs in the image processing space over the years.<p>Most problems tend to be amenable to “classic” techniques (eg OpenCV) and if you can get involved early enough there are a lot of affordances that can be added to make things a lot simpler (e.g registration marks).<p>I’ve also got a small YouTube channel that brings in a bit of revenue from ads and sponsorship.

In the 2000 I used to write a windows tool. It was making me some pocket money until I stopped it in 2015.. I stopped it because it was in the end kinda high maintenance (support mails = time) and I needed to pay taxes, so I basically got 0 or needed even to pay to keep this alive. But until then it was a nice source of passive income. I wish I could make more of these tools. It was nothing big but I spent at least 1 year developing it (I was still learning so I think I could make this in 6 months or less nowadays)

Startups, and tech in general, are becoming more of a tax than a help.<p>Just like North America (and largely Europe too) outsourced its manufacturing know-how to cheaper markets, labor, resources, and regulations, we&#x27;re outsourcing all our business logic, day-to-day functions, and IP to cheaper and cheaper SaaS products. Sure, you can get setup quickly, but it will get torn down just as quickly with deprecations, no support, rising prices, mergers, discontinuations, buyouts, shutdowns etc.<p>What&#x27;s happened is that any small&#x2F;medium business is required to be a mini-tech company to keep the doors open, but paying ever-increasing monthly rent to 15-30 SaaS companies. The tradeoff is that now they don&#x27;t own or operate their own data, have little control over how it&#x27;s queried, displayed, or accessed, all while basically getting zero support (i.e. Google, Shopify, SendGrid, Stripe, the list goes on).<p>I spent 5 years developing an in-house system to run a coffee roaster. All the internal tools, reporting, organic certification, roast logs, traceability, customer service, shipping, wholesale, international, taxes, etc. You name it, any tool we needed, it was built. Prior to this, after 13 years of being in business, they were still wildly unprofitable and doing 600 orders a month. A few years after systematizing the company, now they&#x27;re very profitable and doing &gt;6,000 orders a month.<p>Then I spent 5 years taking that knowledge and toolset and built a V2 for an organic farm to logistics and delivery of fresh produce. Again, after 15 years in business and doing 2500 deliveries a month, it was mildly profitable but struggling under the weight, rigidity, and complexity of an outsourced system. I replaced it with my own system and grew it to 2500 deliveries per week (4x).<p>I then stepped down and started my own company to license out the system I built to run any small or medium organization. They get to own all their data, customize what they want, and I pick up the phone when they need help (crazy idea, I know). Most companies don&#x27;t need bigger, better, flashier, cheaper software. They&#x27;re actually happy to pay for systems that will be flexible when they need, and someone to call if required.<p>All organizations are basically a set of people who need access to customers, addresses, payment methods, products, and orders, with functions to track communication via phone&#x2F;email, make payment transactions, create&#x2F;send PDFs, and report on what was&#x2F;is&#x2F;will be ordered.<p>Running a company on outsourced SaaS is financially-cheap, but it&#x27;s time-expensive, and brittle.<p>My system now runs many multi-million dollars companies, small and medium scale, across many verticals. Whether it&#x27;s shipping thousands of packages, delivering thousands of boxes, or running a local subscription bagel delivery service, or shed manufacturer, or running a Home Owner&#x27;s Association, or running my own tech company, or a fertilizer company, or a youth sports team, or a malting company, or private chef&#x2F;meal-planning service. They all have the same basic needs.<p>For some companies, it&#x27;s my active income, some it&#x27;s maintenance income, some it&#x27;s passive. They&#x27;re all in different seasons, and it fluctuates throughout the year. A couple get busy in the summers, some need special stuff built in the fall for the holidays, some are quiet all year and chug along. But there&#x27;s always someone to help, something to polish, or some JS dependency to remove :)
