Custom Omnichannel Payment Aggregator
Budget: $30 – $250 USD
I need a complete payment-aggregation solution that lets my merchants accept Credit/Debit Cards, Digital Wallets and Bank Transfers through a single, secure interface. Core requirements are a real-time fraud-detection layer and a fully automated recurring-payments module, both exposed via clean REST/JSON endpoints and an easy-to-embed JavaScript/SDK bundle.
Your build must slot smoothly into three environments I already run—standard e-commerce sites, native iOS/Android apps and in-store POS terminals—so consistent API behaviour, webhooks and mobile-ready SDKs are critical. If you’ve previously unified these channels you’ll know the importance of tokenisation, PCI-compliant vaulting and clear onboarding flows for merchants; please weave those into the architecture from the start.
Deliverables
• End-to-end aggregator backend with plugin/SDK examples for web, mobile and POS
• Fraud-detection rules engine and dashboard to review flagged transactions
• Recurring-billing scheduler with webhook notifications, retry logic and clear cancellation flow
• Complete developer documentation and postman collection for quick testing
• A short hand-over session (video or written) so my team can run deployments and future tweaks
I’m happy to iterate in milestones—core transaction flow first, then fraud and recurring modules—so we can go live quickly and harden features in parallel.
