Overview
Payments & PSPs software, built for how the industry really works
Payment service providers and platforms handling multi-rail, multi-currency transactions need orchestration, reconciliation, and fraud controls that scale across markets without manual overhead.
Payments & PSPs teams typically need: payment orchestration and smart routing; cross-border and multi-currency settlement; automated reconciliation against PSP settlement files; crypto on/off-ramp integration; pCI DSS-aligned architecture.
We work as an engineering partner for payments & psps businesses — from discovery and architecture to build, compliance evidence and 24/7 support after launch — so your team can focus on customers, partners and regulators.
The challenge
What payments & PSPs teams struggle with
Silent revenue loss from declines
Poor PSP routing and retry logic quietly loses revenue on every failed or declined transaction, often invisibly to finance teams.
Manual reconciliation overhead
Finance teams spend days each month manually matching PSP settlement files against internal ledgers instead of managing exceptions.
Fraud losses outpacing static rules
Rule-based fraud engines can't adapt fast enough to evolving attack patterns, driving up both chargebacks and false positives.
No single view across PSPs
Running multiple PSPs without a central orchestration layer makes routing decisions, reporting, and risk management inconsistent market to market.
Our approach
How we build for payments & PSPs
Payment orchestration & smart routing
Multi-PSP routing based on cost, success rate, and geography with automated failover, cutting decline rates measurably.
Automated reconciliation
Ledger-matching engines ingest PSP settlement files and reconcile automatically, surfacing only genuine exceptions.
AI-driven fraud detection
Hybrid ML and rules risk scoring layered on existing controls, reducing losses while cutting false positives that slow down good customers.
Crypto on/off-ramp integration
Fiat-to-crypto rails integrated alongside card and bank transfer rails behind a single API.
PCI DSS-aligned architecture
Tokenization and secure architecture review keep sensitive card data out of systems that don't need to touch it.
Typical projects
Payment gateways
Card, wallet and local-rail acceptance with hosted checkout and tokenisation.
Payment orchestration
Smart routing across acquirers to raise approval rates and cut fees.
Merchant platforms
Onboarding, KYB, settlement, payouts and merchant dashboards.
Fraud & risk
Real-time risk scoring, rules and chargeback management.

Pricing is based on the team members you need — tell us your requirements and we will quote your team.
- Start any time after launch
- Hire developers as you need them
- Scale up, scale down or pause
What your team can take on after launch
- New wallets, BNPL and local payment methods
- Checkout conversion improvements
- Merchant dashboards and settlement reports
- New PSPs, payment methods and currencies

Our Approach
Our approach to development methodologies
Our approach to custom software engineering draws on a range of methodologies, each selected to match the needs of your payments & PSPs software project.
Agile Scrum
Best for: Evolving products
Two-week sprints with a working demo at the end of each, so payments & PSPs software priorities can change as you learn from users.
Kanban
Best for: Continuous delivery & support
A visual flow of small tasks with work-in-progress limits — ideal for maintenance, integrations and post-launch improvements.
Fixed-scope (Waterfall-style)
Best for: Well-specified builds
Requirements signed off up front with a fixed timeline and price — best when scope is clear and change is unlikely.
Lean MVP
Best for: New ventures
Build the smallest payments & PSPs software release that proves demand, measure it with real users, then invest where the data points.
DevOps & CI/CD
Best for: Every project
Automated tests, infrastructure-as-code and push-button deployments so releases are frequent, reversible and boring.
Security-by-design (DevSecOps)
Best for: Regulated & high-value systems
Threat modelling, dependency scanning and code review built into each sprint rather than a pen test at the end.
Why we're different
What sets Hurain Technologies apart
Plenty of agencies can build payments & PSPs software. Here is what sets us apart for clients worldwide.
Engineering depth, not a reseller
Your payments & PSPs software project is designed and built by our own in-house engineers — no hidden subcontracting chain between you and the people writing code.
Built for your market, not a template
Payments, tax, language and data-protection requirements for your target market are part of the design from day one instead of retrofitted after launch.
Transparent, senior-led delivery
A named project lead, a shared backlog, fortnightly demos and direct Slack access to the engineers — you always know what is being built and why.
Cost advantage without cutting corners
Delivering from India gives clients worldwide senior engineering at a fraction of typical onshore agency rates, with the same code-review, testing and security standards.
You own everything
Source code lives in your repository from the first commit; IP, infrastructure accounts and documentation transfer to you in full.
We stay after launch
Monitoring, updates and a support SLA mean the team that built your product is the team that keeps it running.
