Which should you choose?

Invoice Ninja: Open-source invoicing, quotes, time tracking and client portal; can be self-hosted.

Refrens: Invoicing and accounting platform for freelancers and small businesses, with quotations, expenses and client management.

The best way to decide is to run the same week of real work through both — most offer a free plan or trial — and compare how long tasks take, what your team prefers, and the total cost for your number of users including renewal pricing.
