A five-minute check, multiplied by every invoice
An accounts payable clerk manually re-adding line items and cross-checking the tax rate takes a few minutes per document. At volume, that's the majority of a finance team's week — spent verifying arithmetic a machine can check in milliseconds.
What the validator actually verifies
Before a document is allowed to auto-submit, fn-validate runs the same checks a careful reviewer would — just instantly, and on every single document instead of a sample.
Errors don't scale down with volume — checks do
Manual spot-checks catch a shrinking share of errors as invoice volume grows, because reviewers sample instead of checking everything. Automated arithmetic validation checks every document, every time, so the error rate stays flat regardless of scale.
Reconciliation isn't judgment work — it's arithmetic. Automate the arithmetic, and your reviewers only see the documents that actually need a human.
