Multi-Partner SaaS Platform with Lead Tracking, Attribution & Settlement System

We are looking for a senior full-stack developer or small senior team to help build a web-based SaaS platform for managing partner offers, customer leads, conversion tracking, attribution, commissions, settlements, and admin workflows. The platform will connect multiple websites, partners, and sales channels into one central system. Users will be able to submit leads or bookings through landing pages or embedded widgets, while the admin system will track customer source, partner assignment, conversion status, commission eligibility, settlement status, and potential clawbacks.
