Overview

The “VAT Number on Bill Attachment Different to Supplier” XBert checks if the VAT number on a bill’s attachment matches the VAT number of the supplier in your accounting software. This helps ensure your VAT reporting is accurate and compliant with South African Revenue Service (SARS) requirements.

What it does

This XBert scans bills with attachments and identifies discrepancies between the VAT number shown on the attachment (such as tax invoices or receipts) and the VAT number recorded against the supplier's contact in your accounting software.

If a mismatch is found, XBert alerts you to review the supplier's VAT registration details or update the bill to reflect the correct information.

How it works

XBert analyses all bills that:

  • Have one or more attachments

  • Are associated with a supplier that has a VAT number recorded

  • Contain a VAT number in the attached document that differs from the supplier’s VAT number

It also checks for valid VAT numbers in the XBert database. If at least one valid VAT number is found on the attachment that doesn't match the supplier's record, the XBert alert is triggered.

Example / Use Case

James runs a construction business and attaches a scanned tax invoice to a bill in Xero. The supplier is Palmers Windows, and in Xero, the VAT number is recorded as 123761282. However, the attachment shows the correct VAT number as 345982333. The mismatch could cause James to incorrectly report VAT to SARS and potentially overpay.

In another case, James mistakenly attaches a taxi receipt from 13-CABS (VAT number: 898934899) to a bill meant for Palmers Windows. While this may not impact the VAT claim directly, it is a poor bookkeeping practice and can result in audit issues.

To resolve this alert:

  • Select "RESOLVE NOW" to view the bill in question

  • Review the attachment and VAT number shown

  • Update the supplier’s VAT number in your accounting software if it was entered incorrectly

  • If the attachment is incorrect, contact the supplier for a corrected invoice or remove the document
