What Happens After You Process the CFDI

Here are the business processes and CFDI stamping flow:

• The employer’s payroll application generates the employees’ CFDI payslip XML files.
• The employer sends CFDI files to their selected Proveedor Autorizado de Certificación (PAC).
  • PACs are SAT authorized providers that stamp the CFDI payslip. They typically also provide technology infrastructure and other value-added services to their customers.
  • PACs prevalidate the CFDI files and send them to SAT.
• SAT validates the CFDI file, and if it's correct, adds the digital stamp otherwise it's rejected with error codes.
• SAT returns the CFDI file to employer/PAC
• Employees can access the stamped payslips through:
  • SAT web portal
  • PACs portal
  • Employer HCM application
