The Monnify invoicing allows you to generate invoices for your customers through the use of our Create Invoice API. For every invoice created, Monnify generates a virtual account number that is tied to that invoice so your customers can make payments to the account or a checkout URL is provided so that customers can make payments with their debit cards.

See Create an Invoice API to learn more.

Invoice Reserved Account (Static invoicing)

Monnify Invoice Reserved Account allows you to reserve an account for your customers to whom you send invoices regularly. This account can be attached to invoices being generated for a customer so that the same account number is received for every invoice peculiar to that customer.

These accounts are slightly different from regular customer reserved accounts as customers cannot pay into these accounts until they are attached to an invoice. See Reserve an Account API for details on how to implement one.


Every invoice created using the Monnify invoice creation both for static and dynamic invoicing expires immediately after payment has been made on the invoice, the maximum duration of an invoice is 6 months.

For static invoices, the virtual account number created just goes dormant till another invoice is created, while for dynamic invoices, a new virtual account number is created for every new invoice.
