BACKS
INVOICE NINJA BACKS THESE RATINGS
Invoices, quotes, expenses and a client portal on your own domain, with no cap on how many clients you bill.
KIMAI BACKS THESE RATINGS
Timesheets with customers, projects, hourly rates and invoices, on a server that never asks how many seats you have.
Neither page tells you which is “better” — they solve the same jobs differently. Pick by the constraint that binds you: RAM, ARM, license, or how alive the project looks.
