PayRequest + Mollie
Monthly Billing & Direct Debit for Bookkeepers
A bookkeeping firm can use PayRequest and Mollie to collect agreed monthly retainers by SEPA Direct Debit. Define the service, recurring amount and payment authorization first, then keep invoices and collection results attached to the customer.

Worked example · monthly administration package
Agree a €150 monthly package, with the applicable VAT and extra-work terms clearly stated. Create the recurring product, assign it to the client and send the authorization link. Bill work outside the package separately when agreed. A submitted debit is not a settled payment; follow the provider’s status.
Connect Mollie and enable SEPA Direct Debit for eligible customers. Create a clearly scoped monthly product.
Review the price, tax, first billing date and cancellation terms, then obtain the client’s payment authorization.
Check the mandate and recurring schedule. Review the first invoice and result before adding more clients.
Give clients portal access to their invoices. Investigate failed collections and check existing attempts before retrying.
Subscription billing requires Business (€20/month). Standard platform fees are 0% while active; Mollie processing fees apply separately. Direct debit can fail or be reversed, so payment follow-up remains part of your workflow. This is client billing, not a replacement for your bookkeeping software.
Set up monthly client billingQuestions before you start
Can I collect monthly client fees without coding?
Yes. Configure the recurring product, customer and billing schedule in PayRequest, connect Mollie and obtain valid authorization. You do not need to write your own payment API integration.
Does an invoice payment authorize future direct debits?
Not by itself. Check the customer’s mandate and recurring setup separately. Manual payment of each invoice remains a different workflow.
Can I invoice extra work outside the monthly package?
Yes. Keep the monthly package scope clear and invoice separately agreed work with its own description and applicable tax. Do not silently change the agreed recurring amount.
