Questions about Avendo

How does Avendo work?: Avendo connects your checkout to multiple payment processors and automatically routes each transaction to the processor offering the best available rate in real time. It works with existing checkout pages, so customers keep the checkout they already know. Merchants also get clearer pricing and processing reports showing what each transaction cost.
Is Avendo a payment processor?: Avendo provides credit card processing for e-commerce businesses by connecting a checkout to multiple payment processors and routing each transaction among them. Rather than being one more single processor, it chooses between processors per transaction based on the best available rate. It works exclusively with PCI DSS compliant processors and gateways.
How much does Avendo cost?: Avendo says it does not bill or charge merchants directly. Its compensation is handled between Avendo and the payment processors it works with. Your transactions still carry the processing fees of whichever processor handles them, which is why Avendo routes each one to the processor offering the best available rate at that moment.
Is Avendo PCI compliant and secure?: Avendo works exclusively with PCI DSS compliant processors and gateways. PCI DSS is the Payment Card Industry Data Security Standard maintained by the PCI Security Standards Council, and it sets requirements for how card data is handled and protected. Ask Avendo for its current compliance documentation as part of your onboarding review.
How do I get started with Avendo?: Contact the Avendo team through the official contact page at avendo.tech. Share how your checkout is built and roughly how many card transactions you process. Avendo works with existing checkout pages, so the conversation focuses on connecting your checkout to its routing rather than rebuilding your store.
