How it works
From bill to paid in three steps.
Capture invoices automatically, see them organized, and pay them with a tap.
01
Capture
Snap a photo of a paper bill, upload a PDF, or forward an email - whatever's easiest.
Optional: connect Gmail to import invoices automatically.
02
Auto-organized
We extract amount, due date, IBAN and reference, then add each invoice to your dashboard.
03
Pay in seconds
See what's due and pay with a generated QR code straight from your own banking app.
Not a bank. We never move money – you always pay from your own banking app.
In action
A calm overview instead of invoices scattered across emails, PDFs and customer portals.
Everything you need to know — at a glance.
