Why a checkout compatibility check stopped an unsuitable application

An online retailer approached We Tranxact for a card payment solution that would work with its existing checkout. It needed both a merchant account to process card payments and a gateway that would connect to the store.

We checked those requirements separately. First, could the provider consider the type of business? Second, could it actually support the checkout the retailer was already using?

The provider confirmed that its available integrations did not support that checkout. We stopped that route before submitting a full application. We explained the reason to the retailer and confirmed we already had the information it had supplied. At the end of the review, we had no confirmed alternative that covered both requirements.

What to ask before you apply

  • Business fit. Can the provider assess the exact products or services you sell, and the markets you sell into?
  • Checkout fit. What is the supported integration for your platform, and how would customers complete payment?
  • Scope. Who provides the acquiring and who supplies the gateway? Ask who handles refunds and support once the setup is live.

If a provider cannot confirm how the checkout would work, settle that question before preparing the full application. Shopify’s documentation, for example, distinguishes providers that complete payment within the store from those that send shoppers to an external checkout.
