Ktraj replaces a supply chain coordinated over phone calls and spreadsheets with a single platform for listing produce, onboarding suppliers and processing orders. The storefront, supplier console and admin share one catalogue and pricing model, while commission and affiliate rules are applied automatically at checkout. Built as a demo, the system illustrates how agricultural marketplaces can digitise sourcing, fulfilment and settlement without losing the regional supplier relationships that make the trade work.

The challenge

What the business was up against

An agricultural supply chain of this size is rarely run on a single system. Buyers negotiated prices by phone, confirmed stock over WhatsApp and reconciled deliveries on paper, so the same product could be quoted at three different prices in one afternoon. Suppliers had little visibility into demand and no reliable way to publish availability, while the operator carried every order in spreadsheets and memory. Stock counts drifted from reality, commissions were calculated by hand, and no audit trail existed when a dispute arose. Growth meant more suppliers, more calls and more errors rather than more throughput.

The solution

What we designed and shipped

We built a single commerce core with a public storefront, a supplier portal and an operations console sharing one catalogue. Products carry structured pricing, units, grades and stock, so buyers see current availability instead of a quoted guess. Orders move through a defined pipeline from placement to fulfilment, with commission and affiliate rewards calculated automatically and recorded against the order. Role-based access separates supplier, buyer and administrator duties, and every stock or price change is written to an audit log. The outcome is one truthful version of the catalogue that all three parties operate against.
