I have 3 non-profit organizations to be put in odoo accounting, that are very limited in their activities, barely a few invoices in/out per month.

These non-profits are allowed to use the "simplified system" of accounting, this means I need only incoming invoices and outgoing invoices ...

The question now is, is there a simplified "chart of accounts" to use for this ?

... or should I slim down the normal chart of accounts, and if so how ?

To be clear : I'm testing Odoo with the community edition, selfhosted on a Synology docker container ...

I see that in the "invoicing" app there are client invoices (= outgoing) and vendor invoices (= incoming) and also payments (bank statements) for both categories ...

hmmmm, maybe that's just all I need then, and I don't need the "accounting" app after all ?

but how do I link the payments to the invoices inside this app ?

and how do I create quarterly VAT statements ?

or am I wrong and do I need the accounting app after all ?

Please tell me ...
