Forum OpenACS Q&A: Re: A Customer's Self-Service Interface to Bug Tracker!?!

Well, to do an accounting system right you need to have a lot of local knowledge in the markets as accounting practices differ from country to country. Therefore our approach is to generate the invoices in OpenACS and then just transfer the list of generated invoices to the accounting program which is certified.

Obviously we could just add the invoice to the internal accounting system based on SQL ledger, but as long as such a solution is not certified by the german tax authorities none of our clients would use it :).

Frank has written a reporting module (non GPL if not mistaken) based on Jasper, so he does have quite some experience in that field.
