Beta Testers
What early users are saying
“An invoicing tool that doesn't want my credit card details just to try it. 👍”
“I was using a Google Docs template before this. The jump in professionalism is funny. Clients now actually pay on time - I think the PDFs make it feel more official.”
“The offline part sold me. I work from cafes and trains a lot. Having an invoicing app that doesn't require WiFi is great.”
“€49 one-time vs €25/month for FreshBooks (and others are even more expensive). I asked the developers for recurring invoices and they already included it in the roadmap.”
“I work in UX, so I notice when software respects the user. No onboarding flows, feature tutorials, or upsell popups. Almost every interaction feels intentional. The only off-putting thing was the Windows warning during installation, but they explained that it's completely safe - just a Windows thing - and they're working on it.”
“I installed it and sent my first invoice the same day. The PDF looked much more professional than the Word template I was using before.”
