How to Build a B2B Payment Platform – Complete Technical Architecture Guide

The Architecture of a Modern B2B Payment Platform

Building a B2B payment platform that handles millions of transactions daily requires careful architectural decisions. This technical guide covers the complete stack — from frontend to infrastructure — based on Laraware’s production-proven architecture serving thousands of businesses.

4-Layer Architecture

Layer 1: Presentation Layer

  • Web Application: Laravel 11 + Vue.js 3 + TypeScript — server-side rendering for SEO, reactive UI for real-time updates
  • Mobile Application: Flutter + Kotlin Native — single codebase for iOS and Android with native performance
  • API Gateway: REST + GraphQL + WebSocket — multiple protocols for different use cases
  • Admin Dashboard: React 18 + Material-UI — fast, responsive admin experience

Layer 2: Intelligence Layer (AI/ML)

  • AI/ML Engine: TensorFlow + PyTorch — fraud detection, commission optimization, predictions
  • Analytics: Apache Spark + ClickHouse — real-time data processing and analytics
  • NLP: BERT + GPT Integration — chatbot, document processing, sentiment analysis
  • Computer Vision: OpenCV + Custom Models — KYC document verification, face matching

Layer 3: Data Management

  • Primary Database: MySQL 8.0 Cluster — ACID-compliant transactions
  • Cache Layer: Redis Sentinel — session management, rate limiting, hot data
  • Search Engine: Elasticsearch — transaction search, log analysis, full-text search
  • Blockchain: Ethereum + Hyperledger — immutable audit trails, smart contracts

Layer 4: Infrastructure

  • Cloud: Multi-Cloud (AWS + Azure + GCP) — no single point of failure
  • Containerization: Docker + Kubernetes — auto-scaling, self-healing
  • CDN: CloudFlare Enterprise — global content delivery, DDoS protection
  • Monitoring: Prometheus + Grafana — real-time system health monitoring

Security Framework

  • Application Security: JWT authentication, OAuth 2.0, API rate limiting, CSRF/XSS protection
  • Data Security: AES-256 encryption, E2E encryption, database encryption, data masking
  • Infrastructure Security: WAF, DDoS mitigation, network segmentation, intrusion detection
  • Compliance: PCI-DSS, RBI guidelines, PML Act, GDPR-ready

Or Simply Use Laraware

Building this architecture from scratch requires 15-30 developers, 18-24 months, and ₹2-5 crore investment. Laraware offers this entire stack ready-made — with 32+ modules, 40+ AI APIs, and complete source code — starting at ₹5 lakh.

Best AePS API Provider India — Comparison Guide 2026

AePS API Provider in India — What to Look For Choosing the right AePS API provider in India is critical for your fintech platform’s reliability, compliance, and profitability. This guide compares the key factors you should evaluate when selecting an AePS API provider, and where NXT Banking fits in this ecosystem. Types of AePS API Providers in India Type 1: NPCI-Certified Bank Pipes (Tier 1) Direct NPCI-certified AePS API providers: NSDL, Fino Payments Bank, Yes Bank, and others. These provide raw AePS transaction APIs but require significant technical integration work and direct NPCI agreements. Type 2: AePS Aggregators / Technology Providers (Tier 2) Technology companies that provide AePS APIs with simplified integration, abstracting the complexity of direct bank pipe management. These include several fintech technology providers. Type 3: Complete AePS Admin Portal Platforms (Tier 3) End-to-end AePS software solutions including transaction processing, admin panel, commission management, KYC, and more. NXT Banking by Laraware operates at this level — it’s not just an AePS API, it’s a complete AePS admin portal with 48 integrated modules. Comparison: Key Factors for AePS API Provider Selection Factor Tier 1 (Direct Bank Pipe) Tier 2 (Aggregator) NXT Banking (Admin Portal) Integration Complexity High (6-12 months) Medium (2-4 months) Low (2 hours) NPCI Certification Required (direct) Via aggregator Pre-certified Multiple Bank Pipes Single pipe 2-3 pipes 4-10 pipes with failover Admin Panel None Basic Full 48-module platform Commission Engine None None 9-level automated KYC Integration None Basic 9-step complete eKYC White Label Support No Limited Complete (own domain+SSL) Why NXT Banking is More Than Just an AePS API Provider Most businesses searching for an AePS API provider actually need much more than just a transaction API. They need: User management for their agent network Commission automation across multiple levels KYC verification for agent onboarding GST/TDS compliance Reporting and reconciliation Fund management and settlements NXT Banking provides all of this in one platform — making it the comprehensive choice for serious AePS software development projects in India. Getting Started with NXT Banking AePS Platform NXT Banking offers 580+ REST API endpoints for custom AePS software development on top of the pre-built admin panel.

How to Build an AePS Platform in India — Step-by-Step Guide for Banks and NBFCs

Building an AePS Platform in India: 2 Approaches There are two ways to build an AePS platform in India: full custom AePS software development from scratch, or deploying a ready-made AePS admin portal like NXT Banking. This guide covers both approaches with honest pros and cons. Approach 1: Custom AePS Software Development Phase 1: NPCI Certification (4-6 months) Before writing a single line of AePS code, you need NPCI certification as an AePS API provider. This involves: business registration, compliance documentation, technical testing, and NPCI certification audit. Budget ₹5-10 lakh and 4-6 months minimum. Phase 2: Core AePS Software Development (6-12 months) Key components to build: Biometric device SDK integration (₹2-5 lakh in licensing) NPCI AePS API integration with VID implementation Atomic wallet engine with Redis locking KYC verification system (Aadhaar, PAN, GSTIN, Video KYC) Commission calculation engine GST/TDS automation Reporting and reconciliation Phase 3: Security Audit and Testing (2-4 months) NPCI requires comprehensive security testing before deployment. Budget for penetration testing, code audit, and VAPT certification. Phase 4: Production Deployment and Monitoring Setting up multi-region deployment, Redis clusters, MySQL replication, monitoring systems, and 24/7 support infrastructure. Total Custom Development Cost: ₹25-80 lakh | Timeline: 18-24 months Approach 2: NXT Banking AePS Admin Portal (Recommended) NXT Banking provides all of the above — pre-built, pre-tested, and pre-certified — deployable in 2 business hours: NPCI-certified AePS with multiple bank pipes 423K+ lines of production code with 1,080 automated tests 16-step atomic transaction engine with Redis locking 9-level distribution hierarchy with automated commission distribution Complete KYC (9-step), GST+TDS automation 580+ REST APIs for custom app development NXT Banking Cost: One-time OTC | Timeline: 2 business hours Which Approach is Right for Your Organization? For most banks, NBFCs, and business correspondents, the NXT Banking AePS admin portal is the clear choice — proven technology, faster deployment, lower risk, and ongoing support from the development team. Custom development only makes sense for organizations with unique compliance requirements, existing technology teams, or those building a fundamentally different product than existing AePS platforms.
