# Why can't I commit my import file?

Any validation error blocks the entire file, even when other rows are ready.

One bad row or missing required column blocks the file. Correct mappings on the review page; fix row contents in your CSV and upload again. Open invoice and bill files allow 500 rows. Bills need an approved vendor; bills covered by an approval workflow must be entered by hand. An invoice number belonging to another customer is an error. Repeated documents for the same contact are skipped, and different vendors can share a bill reference. Ledger dates and both create and posting permissions are checked again at commit. An expired upload needs a fresh file. Follow [Prepare and review an import file](https://demo.qixcount.com/help/moving-to-qixcount/prepare-and-review-a-csv).
