Hi @cws101
Bookkeeping is indeed a fundamental aspect of any business worldwide. However, while the basic principles remain consistent due to accounting standards, the implementation can vary based on business needs, location-specific regulations, tax codes, etc.
As far as I know, there are mostly proprietary APIs for each bookkeeping software / solutions.
If you are specifically looking for an open-source bookkeeping or accounting tool written in PHP, here are a few options:
Akaunting
- Akaunting is a free, open-source, and online accounting software designed for small businesses and freelancers.
- Built in Laravel
- Website: https://akaunting.com/
- GitHub: https://github.com/akaunting/akaunting
FrontAccounting
- It’s a more old-school solution, but it’s robust. It’s primarily for accounting and ERP.
- Written in PHP.
- Website: https://frontaccounting.com/
- Source: https://sourceforge.net/projects/frontaccounting/
InvoicePlane
- More focused on invoicing than bookkeeping but it could be used as a starting point or for ideas.
- Written in PHP.
- Website: https://invoiceplane.com/

OSPOS (Open Source Point Of Sale)
- While this is a point-of-sale system, it has bookkeeping features integrated.

Note that, when using or customizing an open-source tool, it’s crucial to ensure that you comply with all financial regulations relevant to your jurisdiction. It may also be worth consulting with an accountant or financial expert to ensure any system you set up meets your business needs and legal requirements.
