Unified Aggregation API
One API connects over 100 services including recharges, utilities, OTTs, insurance, government, and transport payments—saving integration time and effort.
B2B/B2C Fintech SaaS for Unified Payment Automation
Custom fintech app unifying 100+ services into a B2B/B2C fintech solution with real-time visibility and automated workflows.
Project Overview
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.
Real-World Challenges of Unified Fintech Platforms
Fragmented APIs, service diversity, and compliance burdens make building a seamless b2b b2c fintech solution exceptionally difficult. Below are the mission-critical hurdles we faced.
API Fragmentation Across Billers
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.
Security, Compliance & UX Balance
We needed to implement KYC, PCI DSS, and strong encryption without compromising transaction speed or user experience—balancing regulatory rigor with frictionless payments.
Real-Time Feedback Demands
Users expect instant confirmations for services like recharges. Coordinating synchronous status updates from dozens of third-party providers posed major orchestration and latency challenges.
Scalable, Dynamic Service Onboarding
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 Discrepancies & Reconciliation Complexity
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.
Localized Scalability Requirements
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.
How We Built Seamless Automation
To solve these challenges, we engineered a resilient, modular backend with real-time orchestration, flexible APIs, and automated reconciliation for scalable fintech workflow automation.
Microservices-Based Architecture
We built a distributed system that allows different services to scale independently, reducing downtime risk and enabling seamless updates across critical modules.
API Normalization & Abstraction Layer
A robust middleware layer standardizes interactions with all third-party billers, eliminating inconsistencies and ensuring smooth transactions regardless of source protocol.
Dynamic Service Management Engine
New services can be plugged in using configuration files, not code rewrites. This enabled us to onboard new integrations in days—not weeks.
Role-Based Multi-Tenant Platform
Partners and internal users get role-specific dashboards with customized access control—ensuring data security while empowering franchisees and agents.
High-Reliability Orchestration
Using Redis, queuing, and retry logic, we built a system that recovers gracefully from external service failures—delivering near-perfect uptime and reliability.
Audit Trails & Transaction Monitoring
End-to-end visibility for all transactions via intelligent logging and dispute resolution modules helped reduce failures and speed up customer support resolutions.
Full-Spectrum Fintech Platform Features
Real-Time Transaction Visibility
Smart alerts and notification engines inform users and partners of every transaction update, including recharges, status changes, and refunds.
Multi-Channel Bill Payment Support
Supports mobile, DTH, electricity, water, gas, FASTag, and more—providing comprehensive digital payment infrastructure across regions and industries.
Smart Invoicing & Reconciliation
Automated matching, discrepancy handling, and periodic reconciliation ensure revenue accuracy while saving hours of manual accounting work.
Fraud & Dispute Management Module
Behavior-based anomaly detection, multi-layer authorization, and audit logs protect the system from fraud and improve issue resolution response times.
White-Label & Localization Capabilities
Partners can launch their own portals with language, currency, and branding customizations—ideal for expansion into new geographies.
