How We Engineer Payments
One team for gateways, integrations and compliance.
We design, build and integrate payment systems for platforms handling real transaction volume, connecting you to the providers your business already relies on, then layer in the orchestration, reporting and compliance work that keeps those payments reliable and auditable.
Payment as a Service means a dedicated engineering team building your payment stack, not infrastructure you rent. You keep ownership and control; we take on the engineering and compliance behind it.
We build on the platforms your commerce already runs on, including Shopify, WooCommerce, Magento and custom stacks, so payments fit the system you have rather than forcing a migration.

The difference
Why teams pick us over a payments vendor
We ship our own payment products.PayFast, PayPro, P2M, BaadMay and UnumPay were built by this team. We hit provider and compliance limits before your roadmap does.
Compliance is in scope, not an add on.PCI DSS alignment, tokenization and fraud monitoring are designed in from architecture, so audits do not stall your launch.
You own the system we build.No rented rails or locked processor. Orchestration routes across providers, and the codebase and data stay yours.
40+Gateways behind one integration
1Install, no custom checkout build
UnumPay: the payment platform we built and run ourselves.
UnumPay is a live Devsinc product, a Shopify payment app that connects a store to 40+ local and international gateways in one install, with multiple providers active at once so a single outage never takes checkout down.
Building and operating it is why our payment work lands: we own routing, retries, reconciliation, gateway reporting and PCI DSS in production, not in a proposal. The patterns we hardened for our own merchants are the ones we bring to your stack.

FAQs
Let's talkFrequently Asked Questions
Bring us your providers, platforms and compliance requirements. In one free call we will map the fastest route to a secure, reliable payment system.What is Payment as a Service at Devsinc?
A dedicated team that designs, builds and integrates your payment gateway, orchestration layer and compliance systems, not a shared piece of infrastructure you rent.
Can you integrate multiple payment providers into one system?
Yes. We build orchestration and routing layers that connect merchants to multiple providers with reconciliation and reporting.
Do you build custom payment gateways or only integrate existing ones?
Both. We integrate established local providers, and we build fully custom gateways when an off the shelf option does not fit your business model.
What platforms and SDKs do you support?
Plugins for Shopify, WooCommerce and Magento, plus client and server SDKs for web, iOS and Android.
How do you handle PCI DSS compliance and security?
We implement tokenization, fraud prevention and PCI DSS aligned controls, then provide ongoing maintenance to keep the system compliant.
How long does a payment integration take?
It depends on the number of providers, platforms and compliance requirements involved. Scope is defined during a free discovery call.
