I’m looking for an invoicing system that I can install on my own server that is similar in functionality to Freshbooks. It doesn’t need to have every feature they have, but basically would give me a way to invoice clients and give them a way to the pay online.
Freshbooks charges a monthly fee for their service which I’d like to avoid. I’m looking for something I buy once and then install on my server.
I’ve found a few scripts out there, but they don’t have good support from the developers. It needs to be stable and reliable.
Does anyone use a script like this in their own web business?
