How do startups get their sales transactions into their accounting software (Quickbooks, cloud based software, or whatever is used)?<p>I assume with your typical web app credit card processing is done with Stripe, Braintree, etc., how should each individual sales transaction make it into the accounting software.<p>Do they have each sale end up being recorded along in a PostgreSQL database? But then this needs to be exported to the accounting software that is used. It would make a lot of sense for the entire pipeline to be automated obviously.<p>Really what I'm asking is what is the common practice software architecture to handle a sales end to end?
