We developed a custom fintech app designed to unify over 100+ digital services, including utility bills, recharges, OTT subscriptions, government fees, and more, into one centralized platform. The goal was to streamline fragmented payment systems across B2B and B2C markets by offering real-time transaction orchestration, service onboarding flexibility, and modular expansion. With a focus on scalability, compliance, and automation, the platform provides an end-to-end fintech SaaS for business process automation, enabling white-label partners to serve millions without managing complex integrations or fragmented systems.
Each biller had a different protocol, data format, and uptime policy. Normalizing these disparate APIs into one smooth, consistent layer required deep abstraction and resilient integration strategies.
We needed to implement KYC, PCI DSS, and strong encryption without compromising transaction speed or user experience—balancing regulatory rigor with frictionless payments.
Users expect instant confirmations for services like recharges. Coordinating synchronous status updates from dozens of third-party providers posed major orchestration and latency challenges.
With new services constantly emerging, we had to design a modular framework where services could be added on the fly without affecting the core system architecture.
Billing inconsistencies and failed confirmations from external services had to be resolved automatically and transparently. Reconciliation mechanisms needed to be smart, real-time, and dispute-ready.
Supporting regional government services meant deep localization in compliance, language, and transaction workflows—each of which had to be accounted for in a single platform.
To solve these challenges, we engineered a resilient, modular backend with real-time orchestration, flexible APIs, and automated reconciliation for scalable fintech workflow automation.
We built a distributed system that allows different services to scale independently, reducing downtime risk and enabling seamless updates across critical modules.
New services can be plugged in using configuration files, not code rewrites. This enabled us to onboard new integrations in days—not weeks.
Using Redis, queuing, and retry logic, we built a system that recovers gracefully from external service failures—delivering near-perfect uptime and reliability.
A robust middleware layer standardizes interactions with all third-party billers, eliminating inconsistencies and ensuring smooth transactions regardless of source protocol.
Partners and internal users get role-specific dashboards with customized access control—ensuring data security while empowering franchisees and agents.
End-to-end visibility for all transactions via intelligent logging and dispute resolution modules helped reduce failures and speed up customer support resolutions.
One API connects over 100 services including recharges, utilities, OTTs, insurance, government, and transport payments—saving integration time and effort.
Smart alerts and notification engines inform users and partners of every transaction update, including recharges, status changes, and refunds.
Supports mobile, DTH, electricity, water, gas, FASTag, and more—providing comprehensive digital payment infrastructure across regions and industries.
Automated matching, discrepancy handling, and periodic reconciliation ensure revenue accuracy while saving hours of manual accounting work.
Behavior-based anomaly detection, multi-layer authorization, and audit logs protect the system from fraud and improve issue resolution response times.
Partners can launch their own portals with language, currency, and branding customizations—ideal for expansion into new geographies.
