I need a complete affiliate solution that works seamlessly across both my website and our upcoming mobile apps. The core of the build is a rock-solid commission-management engine that calculates payouts strictly as a percentage of each confirmed sale. Key expectations • Single admin panel where I can set or adjust percentage rates by product, campaign, or affiliate group. • Real-time syncing so the same commission math applies whether a customer checks out on the site or inside the app (iOS and Android). • Secure affiliate sign-up, login, and referral link generation handled through API endpoints my developers can call from the web frontend and the native apps. • Clear payout ledger that logs every sale value, the calculated commission, status (pending, approved, paid), and export to CSV. • Clean, well-commented code and a short hand-off session or written setup guide so my team can maintain it going forward. You are free to choose the tech stack, but please outline it in your bid and be sure it scales for spikes in traffic. If you have done percentage-based commission systems for both web and mobile before, I’d love to see a quick demo or screenshots along with your proposal.
