Introducing KmarApp: Payment Infrastructure for Modern Business | Blog

We are thrilled to announce the public beta of KmarApp — a complete payment infrastructure platform built for fintechs, marketplaces, and SaaS businesses.

After months of development, testing, and refinement, KmarApp is now available for developers and businesses who need a reliable, scalable payment infrastructure.

What is KmarApp?

KmarApp provides everything you need to manage payments on your platform:

Digital Wallets — Multi-currency wallets with double-entry ledger accounting
Payment Processing — Idempotent payment processing with built-in refunds
Merchant Management — Full merchant lifecycle with KYC/AML verification
Webhook Events — Real-time event notifications with HMAC signatures
Banking & Payouts — Multi-bank support with encrypted credential storage

Why We Built KmarApp

We saw that building payment infrastructure from scratch is time-consuming, error-prone, and expensive. Every fintech, marketplace, and SaaS platform needs similar capabilities — wallets, payments, refunds, and settlements — yet most teams end up building custom solutions.

KmarApp was designed to be the payment backend that every platform needs, delivered as a modular, API-first system.
