tl;dr: Use spreadsheet for simple small business accounting, directly, with ability to export to accounting package (and to gen timesheets and invoices), out of the box, without me having to grow my own macros, etc.<p>This may be a very limited use-case, but....<p>I'm a one-man shop. Every month, using my (relatively quick and lightweight) spreadsheet software, I enter time worked for various clients, prepare timesheets and invoices for them... and then re-enter said data into my (slower, less friendly) accounting package.<p>The regular monthly stuff is almost always the same, very cookie cutter.<p>Having an accounting package is almost overkill, but it supports "accountant interoperability"[1] - and using the latter to do the former is definitely overkill. And I've never been able to figure out the automation/recurring capabilities, they seemed geared for more complex enterprises.<p>I hate the fact I enter data multiple times, I hate that I have to use the accounting package to manage expenses, etc., etc. - but integration and automation are complex, definitely overkill for my needs.<p>What I'd really like is the ability to use a spreadsheet for basic double entry bookkeeping (there are only a handful of accounts I use regularly; I can use the accounting package for the infrequent ones) and for entering my time, and have dirt-simple spreadsheet functions for generating client timesheets (sometimes based on the client's format, since my clients are often middlemen), for generating invoices (based on my format), and for generating a file that can be imported into my accounting package periodically.<p>+1 if the spreadsheet knows about regular monthly things and reminds/walks me through them.<p>Lightweight, fast, cross-platform. All the things my accounting package (Windows-only, so runs under a VM) is not.<p>[1] Accountants are like lawyers, IMHO: If you're unsure whether you need one, you probably do; my annual taxes cost me more than doing them myself, but I have greater assurance of minimizing my tax bill while staying off Revenue's radar - audits are expensive.
