Start a free Proof Scan with one invoice and the rates that applied to it. Enter your company and work email, then select the two files. Supported U.S. dollar CSVs can be compared automatically. Other accepted formats need normalization before a result; upload acceptance does not mean analysis is complete. Keep each file under twenty megabytes. Review the upload authorization before submitting. No card is required. If a submission fails after upload, keep the error and contact support before repeating it.
