How to use Blockchain to solve the 'Three-Way Match' problem in ERP systems?

All answers to this question.

Blockchain can revolutionize the Three-Way Match by moving the validation "Upstream." Instead of reconciling at the end, the PO, Shipping Notice, and Receipt are all logged on a shared, immutable ledger as they happen. A Smart Contract can be programmed to trigger a payment immediately once the cryptographic signatures for all three documents are present. This eliminates the need for manual accounts payable audits. Regarding security, you use a "Permissioned Blockchain" where you only share specific hashes of the data, not the raw data itself. This keeps your internal pricing and vendor lists private while still proving the transaction occurred.

How do we handle "Partial Shipments" or "Damaged Goods" in a smart contract without the code becoming so complex that it's impossible to maintain?

• Steven, that’s where "Oracles" come in. You don't put all the logic in the code. If a receiving clerk marks goods as damaged in the ERP, the ERP acts as an Oracle that sends a "Condition Signal" to the smart contract. The contract then pauses the payment and triggers an "Investigation Workflow." You keep the blockchain logic for the "Happy Path" (everything matches) and use your standard ERP workflows for the "Exception Path." This hybrid approach gives you the speed of blockchain automation for 90% of your orders while maintaining the flexibility of your ERP for the messy reality of physical shipping.

The biggest hurdle is getting your vendors on the chain. If they aren't using the ledger, you're back to manual entry. You need a strong "Onboarding Program" for your supply base.

• Karen's right. Blockchain is a network effect technology. It’s only as strong as the weakest link in your supplier network. We usually start with the top 20% of vendors first.
