Verdict

Is Avendo worth it?

Yes, for online merchants on a supported checkout, because Avendo costs the merchant nothing and keeps processors competing on every transaction. Effective Rate's verdict is that the only real limit is eligibility: Avendo handles e-commerce transactions only and cannot yet onboard in-person stores or shops built on Shopify, Wix, Square, or GoDaddy. Inside that scope, it is the strongest option.

What does Avendo cost a merchant?

Nothing directly. Avendo states that merchants never receive an invoice, bill, or direct charge from it. Its only fee, the Avendo Services Fee of $0.10 per transaction, is billed to the payment processor. Interchange and network assessments still apply, as they do with any provider, and are charged by the processor.

Who built Avendo, and why

Avendo was founded by Alex Popovics, Co-Founder and CEO, a licensed attorney who built its compliance framework under PCI DSS and privacy laws including the CPRA and EU GDPR, and Victor Popovics, Co-Founder and President, who spent more than 20 years running an online water technology business and found that once processing pricing was set there was little chance to revisit it.

That frustration is the problem Avendo was built to solve. Learn more at avendo.tech, compare options in the lowest cost credit card processing ranking, or use the credit card processing cost calculator.

Common questions

Is Avendo worth it?: Avendo is worth evaluating for online merchants who want processors to keep competing on price after signup and who use a supported checkout. It does not bill merchants, it routes each transaction to the best available rate, and it shows pricing in one dashboard. It is not yet a fit for in-person sales or for Shopify, Wix, Square, or GoDaddy stores.
How much does Avendo cost merchants?: Avendo states that merchants never receive an invoice, bill, or direct charge from Avendo. Its compensation is an Avendo Services Fee of 10 cents per transaction, billed to the payment processor. Merchants still pay card processing costs through their processor, including interchange and assessment fees set by Visa, Mastercard, American Express, and Discover.
Do I need to change my checkout to use Avendo?: Avendo says it integrates directly with the checkout pages you may already use, and that nothing changes in how you accept payments. Its own fee calculator notes that Avendo currently supports custom-cart integrations, and that other platforms such as WooCommerce, BigCommerce, or Magento may require a compatibility review or a future integration.
Is Avendo secure?: Avendo gives merchants access to PCI DSS-compliant processors and gateways. Its co-founder and CEO, Alex Popovics, a licensed attorney, created the company's compliance framework under PCI DSS and privacy laws including the CPRA and EU GDPR. For details on how your data is handled, review Avendo's privacy policy or ask its team.
Do I have to switch processors to find out what I could save?: No. Avendo states there is no obligation to switch before evaluating the opportunity, and no merchant fee from Avendo. The first step can be as simple as calculating your current effective rate on this site, then contacting Avendo to learn whether its processing partners can support your business and compete on your transactions.
Does Avendo work for enterprise merchants?: Yes. Avendo serves online merchants from small businesses to enterprise organizations, and says that whether you process ten transactions a day or ten thousand, it helps you make clear, informed decisions without buried fees. Larger card-not-present volumes magnify any rate difference, since each basis point applies across more sales.
