It knows which contract this invoice falls under
Which agreement an invoice falls under is decided by a ladder of evidence rather than a similarity score — an explicit human ruling, then a vendor link confirmed by tax registration, then the link alone, then GSTIN equality, then a fuzzy name. Every report names the rung it used.
- └─You can see why a contract was chosen, not just that one was
- └─A person can overrule the inference, and that ruling is stored per invoice
- └─Deciding no contract governs is recorded as a decision, not left as a gap
