I’m currently developing a web application for one of my clients. This client requested a small billing module. The client istelf is small SIP provider. There are several pricing items, plans, etc. All they different types of payment like onetime, monthly, annual. Are there any best practices, good books, articles on blling systems architecure?
Btw the web app based on symfony framework.
Any help is appreciated!
There is usually nothing “small” about a billing system.
I just ran across something called citrusdb. You might want to go through it to decide if you want to build something or just integrate theirs.
Barring that, depending on their business they might be better served just using QuickBooks in combination with an online ordering / payment system.
