Frequently Asked Questions

This is a good and important question: we are not a PSP, but by activating the right lego blocks with us, we succeed in substantially improving the chances of success of a transaction and quickly lower the payment costs. For example, we do direct debit directly with the bank so that the payment is on average 3 to 15 times cheaper and your customer sees the name of your company on his account statement. So also less risk of cancellation. We have a direct link with a number of bank payment methods, eg Tikkie, Rabobank Payment Request, Payconiq, which also lowers the cost. And thanks to our link with smart players such as MultiSafePay, Mollie, Stripe, Adyen, we can still control all payment methods you want, with a different configuration per payment method if needed. And this, always at the best price.

During the intake interview with Twikey, we determine together which payment methods you want to activate and with whom. Once this has been set up, you can easily control everything. You can even differentiate between countries, regions or your own preferred segmentation (difficult payer vs fast payer).

Thanks to our intelligent Payment Switch, it is possible to set up the "routing" to the correct underlying player for each payment method. Do you want direct debit directly with your own bank and also iDEAL via your own PSP and Payconiq and Tikkie directly. All this can be done with the same API set.
