eCOMMERCE PAYMENT GATEWAY
Unify eCommerce checkout & in-person payments with one platform
eCommerce payments don’t stop online
-
An eCommerce payment gateway only handles online transactions, however most eCommerce businesses don’t operate online alone.
Pop-ups, click & collect, in-store returns, events, and physical locations introduce in-person devices, acquirers, and payment flows, and when these are managed separately from eCommerce checkout, that’s where it gets tricky; teams face a mountain of challenges resulting in limited visibility across payments.
But, there is another way…
Aevi connects eCommerce and in-person payments through one orchestration platform, giving you a single, unified way to manage every transaction.
Online + In-Person unification (without rebuilding your stack)
-
Aevi is built for organizations that already run eCommerce payments and need to support in-person transactions without replacing what’s already in place.
This includes:
- eCommerce businesses expanding into physical commerce
- Gateways and PSPs that need in-person payment rails
In both cases, the challenge is the same: eCommerce payments are simple and scalable, while physical payments rely on fragmented infrastructure.
Aevi is an independent in-person payment orchestration layer that connects existing eCommerce payment gateways to physical payment environments through a single API.
This allows online and in-person payments to operate as one system, without rebuilding your eCommerce stack.

eCommerce payment gateway FAQs
-
No. Aevi provides a cloud gateway component, but its core value is in-person payment orchestration. Aevi connects eCommerce payment gateways to physical endpoints and acquirers through one API.
-
An eCommerce payment gateway processes online payments by securely transmitting transaction data between customers, merchants, and payment providers.
For example, when a customer enters their card details at checkout, the eCommerce payment gateway encrypts the data, sends it to the payment processor or acquirer for authorization, and returns an approval or decline in real time so the transaction can be completed.
-
An eCommerce payment gateway processes online transactions. It handles payment data at checkout and connects customers, merchants, and payment providers for digital payments.
Payment orchestration sits alongside the gateway. It connects payment systems, devices, acquirers, and providers across channels, allowing online and in-person payments to be managed together.
For example, an eCommerce payment gateway completes an online checkout, while an orchestration layer ensures that the same payment logic, customer data, and routing can also be used for in-person transactions without adding separate integrations or replacing the gateway.
-
Integration follows a standard, structured path designed to minimize disruption to your existing eCommerce setup. Teams onboard through unified APIs, then configure acquirers, devices, and payment flows through Aevi’s orchestration layer. From there, devices are enabled, transactions are tested end to end, and deployments are rolled out in stages to support scale and resiliency.
This approach connects eCommerce and in-person payments without requiring changes to your existing eCommerce payment gateway.
-
Yes. Aevi is designed to complement existing eCommerce payment gateways, extending them into physical commerce without the need to rebuild the entire stack.
For example, a business can continue using its current eCommerce payment gateway for online checkout, while Aevi connects that same payment logic to in-person devices and acquirers through one orchestration layer. This allows online and in-person payments to be managed together, without changing the eCommerce platform or checkout experience.
