In the UK with have a concept called a micro entity in the tax code. Micro entities have some fairly strict constraints on them (10 employees or less, turnover under £350,000, no foreign currency transactions and so on). Within those constraints the rules are fairly simple and most importantly HMRC provides online forms for filing your books.

I always wondered about starting from those constraints and working back to a basic accounting solution for your typical business person. It would probably cover 90% of the companies in the UK as most of them have really simple requirements.

Luckily I retired before I got around to it.
