Common errors when filling out a CFDI
Issuing Digital Tax Receipts (CFDI) is an essential task to comply with tax obligations in Mexico. However, it can be challenging if the necessary precautions aren’t taken. In this article, we’ll highlight the most common mistakes when issuing CFDIs and provide tips on how to avoid them.
1. Incorrect Use of SAT Catalog Keys
A frequent error is selecting the wrong key from the SAT catalog, whether for products, services, or measurement units.
How to avoid it:
• Verify that the keys used are up-to-date in your system.
• Use automated tools, such as our API, which validates keys before stamping.
2. Invalid or Nonexistent RFCs
Entering an RFC that does not match the recipient or is not registered with the SAT is a common issue.
How to avoid it:
• Implement automatic validations in your system to confirm the structure and existence of the RFC.
3. Missing Required Fields
Failing to include mandatory information, such as the payment method or CFDI usage, can lead to rejections during stamping.
How to avoid it:
• Refer to our API integration guide to ensure all required fields are included.
4. Tax Calculation Errors
Errors when calculating VAT or ISR can result in fines or issues with the SAT.
How to avoid it:
• Automate calculations with a reliable solution that considers current tax rules.
5. Duplicate Folios
Issuing invoices with the same folio can confuse your records and lead to fiscal inconsistencies.
How to avoid it:
• Use an API with support for idempotency keys, like ours, to ensure each CFDI has a unique folio.
6. Ignoring SAT Updates
SAT regulations and catalogs change frequently, leading to errors if not updated promptly.
How to avoid it:
• Stay informed about fiscal updates and use an API that automatically implements these changes.
7. Issues When Cancelling CFDIs
Not following proper procedures for cancellation can cause fiscal conflicts.
How to avoid it:
• Implement cancellation functions that comply with SAT rules, including validations for recipient acceptance.
