End-to-End Event Commerce Platform

I am building an all-in-one commerce infrastructure for the hospitality, weddings and events sector. The platform must let venues and vendors sell, manage and fulfil bookings while giving clients a seamless buying experience. Core functionalities that must be rock-solid • Booking management • Vendor management • Payment processing Within booking management the following components are critical and should be available from day one: • Calendar & real-time availability (Google Calendar sync) • Quotation / RFQ workflow that converts directly into digital contracts Beyond those pillars, the roadmap includes a public marketplace, SaaS dashboards for vendors, workflow automation, full CRM, digital contracts, split payments with automated vendor payouts, customer and event management, analytics and AI-assisted planning tools. Every module has to speak to each other through a clean, well-documented API so that future mobile apps or third-party integrations are straightforward. Deliverables 1. Responsive web application (React or similar) connected to a scalable backend (Node.js, Django or equivalent) 2. PCI-compliant payment layer supporting split payments and scheduled vendor payouts 3. Admin, vendor and customer portals with role-based access 4. Google Calendar integration for instant availability updates 5. Quotation → contract → payment flow that logs every step for auditability 6. Initial analytics dashboard (bookings volume, revenue share, vendor performance) Acceptance criteria • A venue can list inventory, set availability and receive bookings without manual intervention. • A customer can request a quote, receive a digital contract and pay online in one session. • Funds are split automatically: platform fee, vendor payout and any taxes are disbursed according to configurable rules. • Updating availability in Google Calendar reflects instantly on the marketplace calendar. • All data exchanges occur via documented REST/GraphQL endpoints with 90%+ unit-test coverage. I value clear communication, incremental delivery and clean code. If you have experience shipping similar multi-tenant SaaS or marketplace products, let’s discuss an execution plan and timeline.
