Your wallet needs transaction accuracy first, not just polished screens. I have built ecommerce payment flows with MobySign, including refunds. That work included gateway-specific transaction logic and documentation. I can apply that experience to your wallet, payment APIs and history. I use AI-assisted coding to speed work while preserving review quality. I use AI for test generation, API checks and early edge-case discovery. This speeds delivery while keeping financial logic under human review. I would separate balances, transaction states and API failures from React. I would explicitly handle duplicates, failed payments and reconciliation. Your ad and print tracking can use the same auditable transaction model. I would first map wallet flows, API contracts and security boundaries. The result will be easier to test, maintain and extend as your SaaS grows.

You're looking to build a SAAS payment wallet with a focus on those transaction history, security, and payment accumulation. And I see the key challenge here is implementing strong security measures while integrating payment gateways and APIs effectively. I’ll focus on making sure that all transactions are logged accurately, and that the security features meet financial application standards. I can have this ready for you to test first, just to make sure you can see it in action before any payment or award. You’ll only create a milestone once you’re happy with the results, my rate for this project is 24999 INR and I’m ready to start immediately.

First thing I'd lock down is what already exists on your gateway side versus what needs building fresh, since a wallet dashboard's shape depends on whether transaction history comes off a webhook feed or a polled REST call, and that decision touches every screen after it. Once that's settled it's a React front end sitting on your API: transaction history with pagination, a running accumulated payments view, and an ad print/impression frequency module kept separate since it's a different data shape. Security best practices gets said on every brief and skipped on most, so I'd treat input validation and audit logging as first class, every write validated, every state change logged with who and when. 55000 INR over 9 days is my number off the brief as it stands. The one thing that could move it is whether the ad frequency module reads from an existing ad server API or needs raw event ingestion built from scratch. M1: API contract locked, transaction history view with audit logging, 18150 INR (33%), 3 days. M2: accumulated payments view, security-hardened forms and validation layer, 18500 INR, 3 days. M3: ad frequency module wired to the gateway, testing and handoff, 18350 INR, 3 days. First milestone confirms the API shape and ships transaction history before the rest builds on top of it.

Your payment wallet will face PCI compliance issues if you're storing card data without proper tokenization. Most startups underestimate the security audit costs here - we're talking $50K+ if you build this wrong from day one. Quick questions - are you planning to use Stripe Connect or build a custom ledger system? And what's your target transaction volume in the first 6 months? Here is the architectural approach: - REACT: Build a real-time dashboard with WebSocket connections for instant transaction updates and balance changes without page refreshes. - PAYMENT GATEWAY INTEGRATION: Implement Stripe or PayPal with webhook handlers that reconcile payments against your ledger to prevent double-counting. - API INTEGRATION: Design a RESTful API with JWT authentication and rate limiting to prevent abuse during high-traffic ad campaigns. I've built similar wallet systems for 2 fintech SaaS platforms that processed $2M+ monthly. Let's schedule a 15-minute call to map out your compliance requirements before you start coding.

Dear Client, I read "SAAS Payment Wallet Development" carefully and understand you need WhatsApp Business API integration to automate customer communication and business workflows.

Hi, I have experience building SaaS platforms with React, payment integrations, transaction systems, dashboards and API-based workflows. I can build the wallet with clear transaction history, accumulated payment tracking, secure user access and the required advertisement/print tracking in a simple dashboard. I’ll structure the system so transactions and payment statuses are handled reliably, with proper authentication, validation, role-based access and secure API communication. The SaaS architecture can also support multiple users/accounts and future payment or reporting features without needing to rebuild the core system. A few quick questions before we start: Which payment gateway or gateways do you need to integrate? How should the advertisement/print frequency be calculated and recorded? Will each SaaS customer have their own wallet and transaction history? Once I have the payment flow and user requirements, I can confirm the recommended backend, timeline and total cost.

PROPOSAL I’ve gone through the requirement carefully, and the key here is building the wallet as a reliable SaaS payment layer—not just a React interface. Transaction history, accumulated balances, gateway activity and advertisement/print tracking all need to stay synchronized with the backend and protected appropriately. I can handle the React frontend, API integration and wallet workflows, including transaction logs, payment accumulation, gateway integration, user-facing wallet views and admin monitoring. I’ll structure the application so payment states and transaction records are handled consistently, with security controls considered across authentication, API communication and sensitive wallet operations. Our portfolio includes SaaS-style dashboards and API-driven application interfaces, including HSBC Dashboard and Wow Getway, which are relevant references for the management side of this product. Share the payment gateway/API documentation and the expected wallet flow, and I can outline the cleanest architecture and implementation plan.
