In-house C, Android, iOS, embedded, and cloud development with payments DNA — built against the exact hardware, platforms, and acquirers you already use. We ship working software, not tickets.
What is custom payment development? Custom payment development is building a payment application to your exact specifications — terminal software, processor integrations, and transaction flows — rather than adapting an off-the-shelf product.
Discovery to deployment, with everything in between handled by the same team. We specialize in payment technology because that's where our 30+ years live, but our engineers ship across every vertical and every layer of the stack. If it compiles, we've shipped it.
C/C++, Java, Python, JavaScript, TypeScript, Swift, Kotlin, Go, Rust, COBOL when we have to. Legacy mainframes, embedded firmware, native mobile, modern web, serverless cloud — we have engineers who've shipped to all of it, and we deploy them to your project, not a sales pitch.
Native iOS and Android, cross-platform with Flutter or React Native, embedded systems on PAX, Ingenico, Castles, Sunmi, and Clover, payment terminals down to the kernel layer. The right tech for the job, not a one-stack-fits-all answer.
Your business runs on a system that's older than half the team that maintains it. We migrate, refactor, and re-platform without losing the institutional knowledge baked into the original. Modern technologies, better performance, the same business logic that earned you your customers.
The build that doesn't fit a template. The integration nobody else wants to touch. The workflow that's specific to your business and would never be a SaaS product. That's the work we do best — and the work that creates the most durable competitive advantage for the teams we build it for.
The same speed-to-market, the same depth of bench, the same hit-the-ground-running engineering — whether the engagement is a focused build for a startup, a complex platform for a mid-market operator, or a global rollout for an enterprise. Names are anonymized, outcomes are real.
A pre-seed fintech needed a working mobile app, a payment integration, and enough compliance scaffolding to demo to investors — in eight weeks, end-to-end. We staffed up day one with no ramp, shipped the MVP in seven, and helped them close their seed round on the back of a working product instead of a slide deck.
A growing ISO's internal team had been working on a platform rebuild for two years and was still six months out from a beta. They brought us in. We picked up the existing codebase, redesigned the architecture, and shipped a production-ready platform — with new processor integrations, a redesigned merchant portal, and a clean API — in five months total.
A Fortune 1000 payments operator needed a unified terminal application rolled out across eight processors in five countries, with localization, compliance variations, and regional certification all in play. We staffed a 22-engineer cross-functional team, ran four parallel workstreams, and delivered the full rollout in nine months — six months ahead of their original internal target.
Four stages, run in parallel where they can be, sequential where they have to be. No surprises, no scope drift, no project manager telling you the bad news a week before launch. The team you brief is the team that ships.
We map your requirements, technical constraints, and goals into a fixed-scope SOW with a defined timeline and named owners on both sides. No code gets written until we both agree what we're building.
Wireframes, UX, system architecture, technology selection. We pick the stack that fits the problem, not the stack we know best. The deliverable is a build plan you could hand to any engineering team.
Agile sprints with continuous integration, embedded QA from day one, and demos at the end of every cycle. You see progress weekly, not on milestone day. Issues found early are issues that never reach production.
We handle production cutover, monitoring, and ongoing maintenance. Updates, performance optimization, feature enhancements — we stay on as long as you want us to. The relationship doesn't end at go-live.
When your workflow doesn't fit a stock terminal app. Multi-step transactions, a specific hardware combination, a legacy protocol like MDB or Pulse, or a processor integration nobody else has built — that's when custom development is the right call instead of trying to bend an off-the-shelf product around your business. If a stock app genuinely covers your case, we'll tell you that instead of selling you a build you don't need.
Native Android development across Ingenico, PAX, Verifone, Clover, and ID TECH hardware, plus SoftPOS and unattended form factors. We've shipped 300+ terminal apps across this hardware range, so the question is rarely whether we can build on your device — it's what the app needs to do on it.
They're related but distinct workstreams, and we run both. Custom development builds the application; EMV Level 3 certification is the processor and card-brand approval process the finished application goes through. When a project needs both, we scope them together in the same engagement so the app is built with certification requirements in mind from day one, instead of discovering compliance gaps after the fact.
It depends entirely on scope — a focused single-processor integration is a different timeline than a multi-processor, multi-region build. We scope every engagement with a fixed timeline and milestone-based billing before work starts, so you know the schedule going in rather than getting an open-ended estimate.
You do. Custom development work is delivered as your IP, not licensed back to you. That's a deliberate difference from vendors who build you into a dependency on their platform.
Every engagement runs on a fixed-scope Statement of Work, so pricing is quoted against your specific requirements rather than an hourly rate that can run long. We've delivered 900+ projects across a wide range of scopes, from a single processor integration to full multi-processor unattended platforms — ask for a scoping call and we'll return a fixed quote, not a range.
