Frequently asked questions

Your questions, our answers.

Can my customers pay by card without a PayPal account?

In most cases, yes. With a PayPal integration that includes card payments, your customers can pay by card without creating or logging into a PayPal account. It depends on your PayPal account, your market and eligibility, and PayPal decides when to show the card option.

Can I keep my current payment provider?

In most cases, yes. We check how your provider works with your store and combine it with the methods your customers expect.

Which payment method should I choose?

It depends on your customers, your volumes and your countries. Use the configurator or describe your project: we recommend a setup in your quote.

How much does it cost?

Our integration is priced on quote, based on your project. On SumUp’s side, the basic account has no mandatory subscription: SumUp charges a fee on each payment. Fees and plans are set by SumUp and depend on your country.

Are you part of Shopify or SumUp?

No. Checkout Flow is an independent service provider. We carry out the integration on your store; Shopify and SumUp remain your direct providers.
