The invoice goes out with payment built in, and the payment posts back into your own accounts. There is nothing to key in afterwards.
Several hundred companies already send their invoices through Rieck
Built as one flow, not three systems
Payment lives on the invoice. The customer pays from the document itself — no account, no login and no detour through a payment portal.
The ledger stays yours. Master data is pulled from your accounting system, and the payment is posted back into that same ledger.
Overdue is a state. If the invoice goes unpaid it changes status and continues — no new case, no new supplier.
Automatic all the way, traceable at every step
Pick the debtor and add lines with quantity, unit price and discount. VAT is calculated as you go, and the payment terms set the due date.
On issue the next sequential invoice number is assigned, and the PDF is generated and hash-locked. After that the invoice cannot be changed — a credit note is the way back.
Payment sits inside the invoice — not in a portal beside it. The customer picks card, MobilePay or link and is done without creating anything.
The payment is registered, matched to the correct invoice and posted in your own accounting system. The balance follows by itself.
If the invoice goes unpaid it changes status and continues in the same case — reminder, dunning letters, collection and, if needed, the bailiff court.
Rieck sits on top of the ledger you already keep. Data moves both ways, and you keep your chart of accounts, your registers and your auditor.
e-conomic, Visma, Uniconta, Dinero and Business Central. Master data is pulled in, and the entries are written back.
Create, send and fetch invoices programmatically. The same call, whether payment happens by card, MobilePay or FI code.
Get notified the second an invoice changes status — sent, opened, paid, overdue or handed to collection.
Public-sector customers receive the invoice in the Nemhandel format, straight into their own system. No detour by email.
