Set your rules once — catch every issue automatically
Define the checks that matter to your business — blacklisted suppliers, price changes, calculation errors, duplicates, and more. Every document is validated against your rules before it reaches approval.
How it works
Set once, enforced on every document — automatically.
Define your rules
Set up validation checks — flag blacklisted suppliers, detect price changes, catch calculation errors, block duplicates, or any custom condition your business needs.
Documents flow through
Every document uploaded or extracted is automatically validated against your active rules in real time.
Issues get flagged
Documents that fail validation are flagged with clear reasons, routed for review, or blocked from approval — depending on your rules.
What you can validate
Build rules for any check your business needs. Here are the most common ones.
Blacklisted Suppliers
Flag or block documents from suppliers on your blacklist — no invoice slips through.
Price Change Detection
Get alerted when a supplier's prices change beyond your accepted threshold.
Calculation Checks
Automatically verify line item totals, tax calculations, and invoice arithmetic.
Duplicate Detection
Catch duplicate invoices, POs, or payments before they're approved and paid.
Tolerance Thresholds
Set acceptable ranges for amounts, quantities, or dates — flag anything outside bounds.
Custom Rules
Build any validation logic your business needs — combine conditions with AND/OR operators.
