Doorst is a subscription manager for European studios that already invoice from Moneybird or Mollie.
A few years ago I moved from hourly billing to subscriptions. The objection I heard most was “what if I need nothing for a month”, so my subscriptions can be paused. Every tool that tracks that properly bills through Stripe, and I invoice from Moneybird. So does half of Dutch agency land.
Doorst handles the subscription and leaves the invoicing alone. Pause, resume, upgrade, downgrade, and a branded portal per client showing what is running and what has been billed. Payments go through Mollie, Moneybird or Stripe, with iDEAL and Bancontact.
7.50 euro a month for one client, 14.50 for fifteen, 49.50 for unlimited. The last two are founding prices.
