The Payment App Development Reality Check
If you've been quoted ₹50 lakhs or more for a payment app, you're looking at traditional development costs. But in 2026, AI-accelerated development has changed the economics of building fintech products.
Traditional vs AI-Accelerated Development
Traditional Development Approach
Timeline: 6-9 months
Cost: ₹50-80 lakhs
The traditional approach involves:
- Large teams (8-12 developers)
- Manual coding for every component
- Lengthy QA and testing cycles
- Sequential development phases
- High coordination overhead
AI-Accelerated Development (Boolean & Beyond)
Timeline: 8-12 weeks
Cost: ₹38-62 lakhs
Our AI-accelerated approach:
- Small, senior team (3-4 developers)
- AI-assisted code generation and review
- Automated testing and QA
- Parallel development workflows
- Pre-built, tested fintech components

RBI Compliance Requirements
Building a payment app in India requires navigating complex regulations:
Payment Aggregator (PA) License
If you're facilitating payments between customers and merchants, you need a PA license from RBI. Requirements include:
- Net worth of ₹15 crore (increasing to ₹25 crore)
- Fit and proper criteria for promoters
- Robust IT infrastructure and security
- Comprehensive AML/CFT framework
Prepaid Payment Instruments (PPI)
For wallet functionality:
- Authorisation from RBI required
- Full-KYC for wallets above ₹10,000
- Interoperability with UPI mandatory
- Data localisation requirements
Key Compliance Checklist
- [ ] Data stored in India (RBI data localisation)
- [ ] PCI-DSS certification for card data
- [ ] Aadhaar integration for eKYC
- [ ] Two-factor authentication
- [ ] 24-hour transaction reporting
- [ ] Grievance redressal mechanism
NPCI and UPI Integration
Integrating with UPI requires:
Direct Integration (Bank Partnership)
- Partner with a sponsor bank
- Get NPCI membership through the bank
- Invest in certified infrastructure
- Timeline: 6-12 months
Third-Party Integration
- Use payment gateway APIs (Razorpay, PayU, Cashfree)
- Faster to market (weeks, not months)
- Higher per-transaction costs
- Limited customisation
For most startups in Bangalore, we recommend starting with third-party integration for faster launch, then moving to direct integration as volumes grow.
