Payments & Checkout

Payment Gateway Module Development

If you run a payment gateway and need a module for Magento, Adobe Commerce, Mage-OS, Shopify, WooCommerce or OpenCart, we build them from scratch and keep them working afterward. If you run a store and need a gateway live in your checkout, we do that side too. The hard part was never the first release. It's the fifth year.

Payments & Checkout

Anyone can ship version one.

A payment module is not a project that ends. The platform ships a new minor version, your API adds a field, a merchant finds an edge case in a currency nobody tested, and the module either keeps up or quietly starts costing you support tickets and installs. We build gateway modules for payment providers and we stay on them afterward, which is the part most agencies quote for and then move on from. It is also the only part that is hard to fake: a changelog either exists or it doesn't.

What we build

Modules, SDKs, and the checkout around them.

Gateway modules for Magento: Payment modules for Magento Open Source, Adobe Commerce and Mage-OS: admin configuration, checkout integration, order and invoice flow, refunds, and the admin tooling your support team needs.
Modules for other platforms: The same module, built properly for Shopify, WooCommerce, BigCommerce and OpenCart, so your gateway is available wherever your merchants already sell.
Payment orchestration SDKs: Client libraries against a payment API, generated from the spec and covered by drift tests, so the SDK and the API cannot silently diverge.
Checkout and payment integration: For merchants: getting a specific gateway live in a real store, with the tokenization, 3-D Secure, and reconciliation details handled rather than hand-waved.
Compatibility maintenance: Platform upgrades, deprecations, and API changes handled before your merchants notice. This is the work that decides whether a module is still installable in year three.
Documentation merchants can follow: Install guides, configuration docs and release notes written for the merchant developer who has to put your module live, not for us.

The maintenance record

Nobody fakes a changelog.

Every figure below is read from the module's own repository. We would rather show you a real one than describe a good one.

Some of what we build for payments is open source, which means you can judge the engineering directly rather than taking our word for it.

HyperSwitch PHP SDK

MIT licensed

Framework-agnostic PHP client for the HyperSwitch payment orchestration API. MIT licensed, PSR-18 and PSR-3 compatible, with signed webhook verification.

Covers 150 operations of the payment API, with a coverage test that fails the build if the SDK and the spec drift apart.
