PAYMENT SYSTEM FOR SMEs
Payment infrastructure your small business merchants won't outgrow
The infrastructure that keeps merchants from outgrowing you
-
Most small business merchants start with a POS bundle - a single device, a single provider, a checkout that's ready to go on day one.
It works, until the business grows beyond what that bundle was designed for. At that point, you need more flexibility to support your merchants as their payment needs become more complex.
Aevi sits underneath that experience as the orchestration layer, not the bundle itself. We connect in-person payments through a cloud-based platform that works across legacy and modern setups, payment methods, devices, currencies, and markets.
That gives you room to:
Keep merchants longer as they grow, instead of losing them when their needs outgrow the bundle.
Support more complex requirements without moving merchants onto a different stack.
Add capabilities to your SMB offer without building a new integration each time.
Support single-terminal merchants and multi-site operators on one platform.
Built for the ecosystems that serve small businesses
-
Small businesses rarely come to us directly for payment services - they get them through the PSPs, ISOs, banks, and ISVs already serving them. Our platform gives you the infrastructure to deliver SMB merchant services that can scale with your merchants, without replacing the systems or provider relationships already in place.
That means you can extend your offering over time, adding new payment capabilities and services through the same underlying integration as your merchants scale.
Why PSPs and ISOs choose orchestration over a bundle
-
Reselling a bundled POS solution can be the quickest route to market, but it means building your proposition around another vendor's platform. Their hardware, roadmap, and commercial priorities set the limits of what you can offer, making it harder to differentiate and to support merchants as their requirements grow.
Orchestration underneath your offer changes what you control:
You keep the merchant relationship
Aevi sits underneath your offering, not in front of it.
You aren't waiting on someone else's roadmap
Add or switch acquirers, devices, and payment methods on the same integration.
You can build a different offer
Combine the devices, services, and pricing that suit each merchant segment, instead of selling what every other reseller is selling.
Growth stays with you
When a merchant adds locations, markets, or channels, you support that expansion instead of losing it.
A stronger platform for small business merchant services
-
Merchants can go live with the right setup for today, then extend it to new locations or markets as their needs change.
-
Card payments for small businesses typically need to work across more than one channel. Our platform keeps in-person payments at the core, while giving you the option to connect online payments through the same cloud-based platform.
-
Aevi supports legacy payment setups alongside modern card payment machines for small business merchants, so you can build on the hardware already in place.
-
One integration supports multiple payment methods across devices, currencies, and markets, while maintaining a consistent and secure payment experience.
-
See connected devices, locations, and acquirers from one place, instead of piecing information together across separate systems.
-
Add a new acquirer or service, or switch one out, without touching the terminal in the merchant's hand.
-
Push updates, manage configurations, and roll out new payment experiences across a merchant's estate from a single platform.
-
Loyalty, tipping, industry-specific workflows, and future services beyond payments can sit alongside the main payment experience, helping merchants get more value from the devices they already use. You can use the same platform to tailor your offer to different merchant segments and introduce new services through the existing payment journey.
A flexible, vendor-agnostic model for small business card payments
-
Most card payment tools for small businesses are built to get a merchant started quickly - not to keep up once they grow. Aevi's orchestration platform is designed for the complexity that comes after: more locations, more markets, more devices, more partners.
On a closed, all-in-one SMB payment stack
Locked to one device and provider
Expansion can mean another separate setup
Fixed checkout, closed to extras
Expansion often requires market-by-market setup
Outgrown it? Move to a new payment stack
With Aevi's orchestration layer
Vendor-agnostic, multi-acquirer routing
Extend the same payment setup across new sites
App marketplace for loyalty, tipping, and more
Built-in support for multiple currencies and markets
Add complexity when it’s needed on the same core platform
Built for merchants that won't stay small forever
-
The merchant starting with a single terminal today could be managing multiple sites, markets, and device types in just a few years. Whether they do that with you depends on what sits underneath their payments now.
One store, many locations
Merchants can start with a single store and extend their payment setup across multiple locations. Provider connections and device configurations can be managed through the orchestration layer - giving you centralized control as the estate grows.
One country, multiple markets
As your merchants expand into new markets, Aevi supports local payment requirements, currencies, and providers without adding unnecessary complexity - extending your reach without starting again.
One device type, mixed estate
Merchants can introduce new device types and payment methods through their existing integration - connecting attended and unattended terminals with mobile payment devices for small business merchants within one estate.

Aevi gives PSPs, ISOs, banks, and ISVs a vendor-agnostic payment platform for delivering small business merchant services, with in-person payments at the core and online integration where it’s needed across legacy and modern setups.

-
Card payment systems for small businesses should make it easy to get merchants live while giving them room to add locations, devices, payment methods, and providers as their needs grow. Aevi gives PSPs, ISOs, banks, and ISVs the orchestration infrastructure to support that growth through one connected platform.
-
With a closed bundle, that often means rebuilding from the ground up. With Aevi, a merchant extends the same integration instead - adding acquirers, devices, or markets without starting over.
-
Yes, merchants can expand from one store to many, and from one market to several, on the same core integration - extension, not reintegration.
-
That's not a problem - our platform is flexible enough to work alongside legacy systems already in place, as well as new ones.
-
Yes. We give you the flexibility to support more than card payments, with the option to add new payment methods and value-added services such as loyalty or tipping alongside your merchants’ existing payment setups.
