SaaS Multi-Vendor Marketplace Development

I’m ready to launch a full-scale, multivendor marketplace offered as a SaaS. Each business that signs up should receive its own storefront, pay a recurring subscription, and be charged a commission on every sale they make. Shoppers will still enjoy a traditional B2C experience on the front end, while an additional, access-controlled Wholesale/Distributor area will let registered buyers place bulk orders at negotiated prices.

Scope in brief
• Web platform plus companion iOS and Android apps must share one back-end, so inventory, orders, and analytics stay perfectly in sync.
• Technology stack is open—whether Shopify, Magento, or a custom React/Angular build—so long as the total cost remains competitive and the codebase is easy to maintain.
• Credit and debit card payments need to flow through a reliable gateway from day one; future extensions to PayPal or bank transfer should be kept in mind.
• Vendors will need dashboards for product, pricing, shipping, and subscription management, while I (as super-admin) can set plan tiers, commission percentages, and review payouts.
• The wholesale section must sit behind role-based permissions, showing distributor-level pricing, minimum quantities, and pallet/box shipping options invisible to retail shoppers.

Deliverables
1. Responsive web application with vendor, distributor, and admin portals
2. Native iOS and Android apps published under my accounts
3. Payment gateway integration for credit/debit cards with PCI-compliant handling
4. Subscription billing module (monthly or annual) and variable transaction fee engine
5. Source code, basic unit tests, deployment instructions, and a short video walk-through of all major flows

Acceptance
I’ll consider the project complete once a demo store can:
• Onboard a new vendor, charge their subscription, list a product, accept a retail order, and disburse funds after commission;
• Restrict a separate wholesale buyer to distributor pricing only;
• Reflect every action across web and both mobile apps in real time.

If this outline matches your skill set and you can advise on the most cost-effective stack to hit these goals, let’s discuss milestones and timeline.
