When descriptions differ between documents, Aviara AI match reconciles lines on meaning rather than exact text, so a PO line and an invoice line describing the same item in different words still match. This is where Aviara Connect is different. The AI reasoning runs inside a custom rule engine we built to validate every match, so the intelligence is governed by your logic and tolerances instead of left to guess. Those tolerances, set by vendor or by category, decide how much price or quantity variance is acceptable, so small legitimate differences never become exceptions.
