What is CFDI electronic invoicing and why is it mandatory in Mexico?

CFDI (Comprobante Fiscal Digital por Internet) is a digital document that replaced paper invoices in Mexico. SAT (Mexico's tax authority) made it mandatory to ensure tax transparency and facilitate auditing. Every taxpayer must issue CFDI 4.0 invoices to document income, deductions, and business transactions.

What is an authorized PAC and why do I need one?

A PAC (Proveedor Autorizado de Certificación) is a company certified by SAT to validate and digitally stamp invoices. Authorized PACs ensure tax documents comply with Mexican regulations by assigning a unique fiscal UUID that certifies legal validity.

What's the difference between CFDI 3.3 and CFDI 4.0?

CFDI 4.0 is the updated version mandated since 2022. Key differences include new required fields (postal codes), stricter tax regime validation, and more precise product descriptions.

What is the Waybill (Carta Porte) and who needs it?

Carta Porte is a mandatory CFDI supplement for transporting goods across Mexico. It documents origin, destination, cargo, and vehicle information.

How do I validate if an electronic invoice is legitimate?

Verify the UUID on SAT's portal or use specialized tools. EdiFactMx has a validator that checks authenticity and queries real-time SAT status.

What are the benefits of using a cloud-based invoicing system?

Cloud invoicing offers 24/7 remote access, automatic SAT updates, automatic backups, multi-user access, and reduced IT costs.
