Instant Liquidity for India's MSMEs - Transform unpaid invoices into instant working capital through blockchain-powered invoice financing.
InvoiceChain is a decentralized invoice financing platform built on Polygon blockchain that enables Micro, Small, and Medium Enterprises (MSMEs) to get instant funding for their unpaid invoices. The platform uses collaborative verification, proof metadata, and smart contracts to reduce risk and provide competitive interest rates.
- Get Paid in 24 Hours, Not 90 Days - Stop chasing payments and get instant liquidity
- Zero Collateral - Your invoice is the asset. No property or FD needed
- Dynamic Discounting - Upload video proof & GPS data to lower your interest rate by up to 2%
- No Debt Trap - It's not a loan. It's an advance on money you have already earned
- High-Yield Assets - Access short-term, high-yield invoice financing (Avg. 18.5% APR)
- Low Default Rate - Programmatic verification reduces risk (0.2% default rate)
- Immutable Data - All invoice data and delivery proof is hashed on IPFS and anchored to Polygon
- Smart Contract Settlement - Repayments are enforced by code with automatic fund routing
MSME uploads invoice. Proof metadata (photos/GPS) is hashed to IPFS. Invoice is minted as an NFT on Polygon.
Buyer receives notification. Verifies goods delivery and quality on-chain. Smart contract updates risk score.
Banks bid on verified invoices. Dynamic discounting engine calculates real-time rates. Funds released instantly.
Buyer pays on due date. Smart contract automatically routes principal + interest to Bank and surplus to MSME.
