An innovative payment solution for all your business needs

Payment Mix enables you to combine multiple payment methods, so you can tailor the SlimPay payment solution to the needs of your company or your distributors. With SlimPay’s omnichannel payment solution for distributors, you can collect payments wherever your customers may be. This comprehensive payment platform has been designed to meet the needs of your company and of your distributors.

SlimPay is one of the only payment service providers that gives you the option to combine multiple payment methods. Our Payment Mix solution allows an e-commerce store or merchant to, for example, take the first payment by card (with our Card product) and subsequent payments by automatic SEPA Direct Debit (with our Direct Debit product).

This is a useful option for companies that send devices or equipment to the customer at the start of a subscription, for example, an internet service provider who provides their customers with a router so they can connect to the internet. Because the first payment is accepted instantly by card (or other payment method), the merchant is able to secure this first payment and ensure they do not make a loss in the event of non-payment. If a merchant opts for Direct Debit only, they would only become aware of a non-payment issue when the first monthly payment falls due, and could potentially not only lose the payments for the weeks or months of service, but also make a loss on the costly equipment that has been sent to the customer.

In the event of a failed payment, the merchant is able to offer their customer an alternative payment method, thanks to our omnichannel solution. A failed Direct Debit payment can be recovered via a payment link, which gives the customer the option to pay by card or by SlimCollect (instant payment directly from a bank account). By using a combination of payments with Payment Mix, a merchant is able to recover funds while ensuring that customers do not lose access to their service or product.


You can use the SlimPay tools and API to perform a range of actions to manage your direct debit mandates, such as create a mandate, search for or obtain a report, cancel a mandate and change a client’s bank details.

A card alias (or create card tokens) is used as an identifier for a bank card number and its expiry date. It is linked to a single creditor. You can track the status of every card alias and create payments for it on the SlimPay Dashboard.

If the codes RET or REJ appear on your report or as payment statuses, it means that these SEPA direct debit transactions have been rejected or refused. The transactions are called R-Transactions. Depending on the R-Transaction code, SlimPay allows you to replay some failed payments, either manually or automatically, using Automatic Retry.
