FIRS Validation
Rule checks that confirm invoice payloads meet required schema and compliance constraints before acceptance.
What It Means
Validation typically covers mandatory fields, tax math, identifier quality, and format-level consistency. Failures must be corrected and resubmitted.
Why It Matters
Strong pre-submission validation reduces rejection rates and keeps invoice-to-cash cycles predictable.
