Your customer registers a card or MobilePay once. After that the invoice is created, the amount is collected and the payment is booked — every period, on the date you set.
Several hundred companies have automated their flow with Rieck.
Three steps that used to be done by hand
The invoice is created on the day. The agreed amount, interval and VAT rate become a real invoice on your own letterhead, with a number of its own.
The amount is charged to the card. The card or MobilePay is charged on the due date. Your customer sees one line on a statement and gets on with the day.
The entry lands in your ledger. The payment is matched to the right customer and invoice, and the entry is written back to your accounting system.
The subscription runs until you stop it
Card or MobilePay, in a few seconds. The card itself sits with the payment provider, and you see only the last four digits — enough to recognise the card, too little for anyone to use.
The amount, interval and VAT rate become an invoice with a sequential number, sent on your own letterhead. It enters reminders and reconciliation exactly like every other invoice you issue — so your auditor can follow the run, and an unpaid collection can move on without being set up from scratch.
Cards expire and accounts run dry — it happens to every subscription business. So Rieck tries again after three days, asks your customer for a new card, and sends the reminder if the amount is still open. You only hear about it if it keeps happening.
How many agreements are running, what they are worth per month, and what goes out next — gathered on one page. An agreement can be paused and picked up again, without the subscriber having to be set up from scratch.
There are four plans. The lowest has no fixed monthly price, and the payment fee is at its highest there; every step up brings the fee down. The card cost is already part of the rate, and none of the four puts a ceiling on how many subscribers you can run.
A fixed interval, or a larger amount split across several collections — both are set up in the same place. And your customer stays inside your world the whole way.
The same amount every month or every quarter, collected on the agreed day. Set up once.
A fixed fee at a fixed interval. The agreement is signed with MitID, and the billing runs on from it.
A larger amount cut into several collections, with the same follow-up behind it if one instalment fails.
Every subscriber gets a simple page on your own domain with the next payment, the amount and the payment method — from the Pro plan and up.
