Enabling acquirers, banks, and enterprise merchants to
Run Stripe-like payment platforms in-house — under their own brand, with full data ownershipNo internal payments team needed. We bring the platform, the engineers, and the knowledge. You get a live, production-ready operation — and full independence from day one.
Our fintech engineers install UNAK on your servers or private cloud. We connect your processors, configure routing rules, and go live. You don't need a single payments hire.
Weeks, not monthsFor the first 6 months, our team works alongside yours. We handle optimization, routing, compliance, and troubleshooting. Your team learns by doing — not from a manual.
6-month knowledge transferYou own the platform, the data, the code, and the logic. Extend it yourself, hire a team, or keep us on retainer. No dependency, no lock-in, no per-transaction tax — ever.
Full independenceOffer convenient payment options to customers worldwide. Scale gracefully with local payment methods and third-party APIs. Run every transaction through the best provider and re-route failed attempts. Make the most out of your payment data. Manage risk with robust security practices.

1–2 weeksUNAK runs alongside your existing system. Both process live transactions. We compare results, validate routing logic, and confirm compliance — before any cutover.
4–8 weeksExisting card tokens are migrated to the UNAK Tokenization Vault with zero customer re-authentication. Existing contracts with Visa/Mastercard and acquirers are preserved.
Transparent to cardholdersTraffic shifts progressively — 5% → 25% → 50% → 100%. Full rollback capability maintained at every stage. No big-bang migrations.
Rollback at any stageUNAK handles 100% of traffic. Legacy system decommissioned on your schedule. Post-migration monitoring for 30 days included.
Full support post-launchEvery PSP and orchestrator charges a percentage of every transaction — forever. With UNAK, you pay once for the infrastructure and keep the margin.
Most businesses only see the headline PSP rate. Below are all the layers of cost — many hidden in the small print.
