Use this short checklist to reduce avoidable invoice rejections.
1) Validate required fields
- unique invoice number
- service/performance date present
- plausible tax rate and tax amount
- clear payment terms
2) Validate totals and tax logic
- line sums match intermediate totals
- tax amounts are rounded consistently
- grand total matches the final invoice amount
3) Validate send readiness
- recipient accepts the selected format
- file was not post-processed in a way that breaks consistency
- document is stored in an archive-ready way
A repeatable pre-send checklist usually lowers correction effort significantly.
