Why Choose This Project?

In traditional supply chains, invoice fraud, delayed payments, and lack of transparency severely impact suppliers and vendors. This project leverages blockchain to create a tamper-proof and transparent system for invoice issuance, tracking, and early payment financing.

It allows suppliers to upload invoices that can be verified, approved, and financed via smart contracts — eliminating intermediaries, reducing fraud, and ensuring trust between stakeholders (buyers, suppliers, and financiers).
