Integration

How payment routing integrates with your checkout

Last updated: November 2026

Avendo integrates directly with the checkout pages you already use and routes each transaction behind the scenes. Customers keep the same checkout; the processor decision moves from your contract to each individual transaction.

Does Avendo work with my checkout platform?

Yes if you run a custom cart, which is the integration Avendo supports today. WooCommerce, BigCommerce and Magento or Adobe Commerce may need a compatibility review. Shopify, Wix, Square and GoDaddy stores cannot be onboarded yet, and Avendo says it is working toward supporting them.

The onboarding procedure

1
You share basic business details
Processors need them to approve a merchant account: to verify who you are, where funds are deposited and how the business operates.
2
Avendo sends it to eligible processors
Avendo collects everything in one place and sends it out for review, so you only apply once.
3
You connect your checkout and start processing
Once approved, you process through Avendo, with processors competing on price for each transaction and all data in one dashboard.

What to have ready before you apply

Your SSN, EIN or ITIN, whichever tax ID applies
A voided check or bank letter showing account and routing number
Three months of processing statements, or three months of bank statements
Business address and contact information
A government-issued ID such as a driver's license or passport
Articles of Organization or Incorporation (requested on the registration form)

Timeline and engineering effort

Avendo estimates about 10 minutes for its application; its registration page lists 15 minutes. Because you apply once, there is no repeated paperwork per processor.

Avendo does not publish an engineering timeline for checkout integration. For enterprise teams, scope it like any payments change: sandbox testing, token handling for stored cards, webhook and reconciliation mapping, and a staged rollout. Ask Avendo for the integration documentation during your first call.

Common questions

See all 45 answers in the FAQ

Which checkout platforms does Avendo support?: The service currently supports custom-cart integrations. WooCommerce, BigCommerce and Magento or Adobe Commerce may require a compatibility review or future integration. Stores built on Shopify, Wix, Square or GoDaddy cannot be onboarded today; support is being worked toward.
We run a custom checkout. Is that a good fit?: Yes, a custom cart is the integration the service supports today. Enterprise and digital teams with their own checkout are the most direct fit, especially for e-commerce, online subscriptions, SaaS and memberships. Contact the service to confirm the integration path for your stack.
Can Avendo route in-person or point-of-sale payments?: Not yet. The service is currently available only for e-commerce, card-not-present transactions. It cannot onboard in-person or point-of-sale businesses today and says support is coming. Teams with mixed channels can still route their online volume.
How long does the Avendo application take?: The application takes about 10 minutes, and the registration page lists 15 minutes. You apply once; everything is collected and sent to eligible processors for review, so you do not repeat paperwork for each processor.
What documents do I need to apply?: Have your SSN, EIN or ITIN, a voided check or bank letter showing account and routing number, three months of processing statements (or bank statements), business address and contact details, and a government-issued ID. The registration form also asks for Articles of Organization or Incorporation.
Do I have to apply separately with every processor?: No. The service collects your information in one place and sends it to eligible processors for review, so you apply once. Processors that accept your account then compete on price for each transaction you process.
