I’m taking my wholesale business online and need a purpose-built B2B web platform that feels as seamless as the best B2C stores but is tailored to professional buyers and sellers. Core functionality • Product listings: tiered pricing, bulk-order units, rich media, and search/filter tools. • Order management: real-time stock checks, quotes that convert to orders, status tracking, and downloadable invoices. • User accounts: secure registration, role-based dashboards, and self-service profile management. User roles to be fully supported • Admin – complete control over catalog, users, pricing rules, and analytics. • Seller – dedicated storefront, inventory sync, and order handling. • Buyer – quick re-order, saved carts, and credit-line visibility. Essential integrations Payment gateways for card and alternative B2B terms, direct hooks into our CRM system for lead and customer syncing, and two-way connectivity with our inventory management system so stock, SKUs, and fulfillment steps stay accurate across all channels. Deliverables 1. Responsive web application (desktop & mobile) with modern UI. 2. REST/GraphQL API layer documented for future mobile app use. 3. Seamless integrations tested end-to-end with the specified payment, CRM, and inventory tools. 4. Admin panel with granular role permissions and analytics dashboard. 5. Deployment pipeline and production hand-over with source code, unit/integration tests, and setup documentation. Acceptance criteria will center on: flawless role segregation, zero-error API responses, and successful data exchange with the three external systems under live test conditions. If you’ve built B2B marketplaces or multi-tenant SaaS platforms using stacks such as React, Vue, Angular, Node, Laravel, or similar, your experience will translate perfectly here. Clean code, clear documentation, and maintainable architecture matter more to me than the specific language or framework choice—as long as it meets the above requirements and scales gracefully.
