The World of Payments

Why payment infrastructure is broken

Problem
  • Infrastructure is standardized, but implementation is not. 95% of payment code is identical across companies, yet businesses build it from scratch every time.
  • Fragmented & Incompatible. Current solutions are isolated silos that don't talk to each other.
  • The Cost of Inefficiency: $2+ Trillion in annual transaction fees paid for technology that should be a commodity.
Solution
  • Product, not Service. We replace expensive custom development with a standardized, reference infrastructure.
  • Economies of Scale. UNAK delivers the "Core 95%" out-of-the-box, eliminating the need for redundant software development.
  • True Commoditization. We do for payments what Cloud did for servers: standardize the rails so enterprises can focus on their business, not the plumbing.

Enabling acquirers, banks, and enterprise merchants to

Run Stripe-like payment platforms in-house — under their own brand, with full data ownership
How it works

From zero to full payments operation — in three steps

No 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.

1
We Deploy & Configure

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 months
2
We Run It With You

For 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 transfer
3
You Own It Fully

You 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 independence

Migration

Zero-downtime migration.
We've done it before.

Every business comes with a legacy system. Our engineers have migrated payments infrastructure from Nets, ACI Worldwide, in-house builds, and major PSPs — without a single hour of unplanned downtime.

1
Discovery & Architecture Review

We audit your current stack — PSP contracts, integration points, token vault, fraud tooling, reconciliation flows. We map what stays, what moves, and what improves.

1–2 weeks
2
Parallel Run

UNAK runs alongside your existing system. Both process live transactions. We compare results, validate routing logic, and confirm compliance — before any cutover.

4–8 weeks
3
Token Migration

Existing 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 cardholders

Gradual Traffic Cutover

Traffic shifts progressively — 5% → 25% → 50% → 100%. Full rollback capability maintained at every stage. No big-bang migrations.

Go Live & Decommission

UNAK handles 100% of traffic. Legacy system decommissioned on your schedule. Post-migration monitoring for 30 days included.

Pricing model

License fee, not transaction fee.
The difference is massive.

Every PSP and orchestrator charges a percentage of every transaction — forever. With UNAK, you pay once for the infrastructure and keep the margin.

Traditional PSP / Orchestrator
Per-Transaction Model
You pay a percentage of every single transaction — forever. The more you grow, the more you pay.
Monthly fixed fee + per-transaction fee
  • Vendor owns the platform
  • Vendor owns or limits your data
  • Cost scales with every transaction
  • Limited integrations — vendor catalogue only
  • No customization outside roadmap
  • Vendor lock-in from day one
  • SLA tied to vendor's uptime, not yours
