The problem
What it replaces
Companies buying IT services, hardware or software collect quotes by email, compare them in a spreadsheet and hope the vendor delivers. Vendors cannot prove they are verified, payments are made on trust, and disputes have no record to settle them.
This marketplace verifies businesses and vendors, lets clients post requirements through category-specific forms, runs bidding with shortlists and clarifications, and then manages the engagement — contracts with milestones, three fulfilment workflows, escrow and wallet, invoices with VAT, messaging, reviews and disputes. Bilingual with right-to-left layout.

Post requirements, invite vendors, compare and shortlist bids, and manage contracts with their team.

Architecture
How the pieces fit together
One Node service serves the API, the web app and a WebSocket server for messages and notifications. Payments are a separate module with injected dependencies, so the gateway can be chosen per market.
