Yesterday I installed the open source program called simpleinvoices in order to create products, customers and invoices. I really like it. Only problem I faced was that I used and exclamation sign in my database password. This resulted in a white page during installation. Turns out that simpleinvoices is shipped with the ZendFramework and that does not handle the “!” character properly 🙂
The code can be found here. Nice clean solution for invoicing if you ask me.
