General Features

The Stamping webservice has the ability to process the following fiscal receipts:

• Digital Fiscal Receipts e-Invoicing (CFDI) versión 3.3
• Digital Fiscal Receipts e-Invoicing that supports Retentions and Payment Information on version 1.0
• Digital Fiscal Receipts e-Invoicing (CFDI) versión 4.0
  New
• Digital Fiscal Receipts e-Invoicing that supports Retentions and Payment Information on version 2.0
  New

To certify a fiscal receipt (stamp) that contains a fiscal folio (UUID), the Certified Provider for e-Invoices (PCCFDI) has to follow the next steps:

1. Verify that the XML (receipt) follows the structure defined by SAT on Anexo 20 and the complements within the receipt.
2. Fulfill the validations the SAT requires from the PCCFDI.
3. Generate the Digital Fiscal Stamp for the receipt.
4. Deliver the Fiscal Receipt (Stamp) to the issuer of the receipt.
5. Deliver the Fiscal Receipt certified to the SAT.
6. Archive the Certified Fiscal Receipt on its digital vault.

Additionally, the stamping service has the ability to generate a printed form according to the needs of the issuer and include the necessary information to be shown on this receipt. To obtain the printed version of the CFDI the client needs to have that service active, recover it through Sovos' REST API. For details on how to get this PDF check this link.

What do I need?

To use this service, you will need:

• A service contract with Sovos. If you don't have one: please send an email to sales-mexico@sovos.com

• The XML of the receipt for stamping must consider the following:
  • Fulfill the schema provided by the SAT for each receipt.
  • Generate the digital stamp of the receipt.
• Be able to use a webservice published on the Internet through a safe connection (SSL).

Validations for the Certification Process (Stamping)

A receipt can be certified by a PCCFDI as Sovos after fulfilling the following validations:

❖ Structure

The fiscal receipt is validated against the XSD Schema (XSD) published by SAT.

• Digital Fiscal Receipts on the Internet (CFDI):
  • Scheme for CFDI version 3.3
  • Scheme for CFDI version 4.0
• Digital Fiscal Receipts on the Internet supporting Retentions and Payment Information:
  • Scheme for Retencioness version 1.0
  • Scheme for Retencioness version 2.0

SAT also requires fulfilling the following features of the receipt:

❖ Prefix

• On CFDI 3.3 the prefix for the namespace http://www.sat.gob.mx/cfd/3 must be cfdi
• On CFDI 4.0 the prefix for the namespace http://www.sat.gob.mx/cfd/4 must be cfdi
• On Retenciones 1.0 the prefix for the namespace http://www.sat.gob.mx/esquemas/retencionpago/1 must be retenciones
• On Retenciones 2.0 the prefix for the namespace http://www.sat.gob.mx/esquemas/retencionpago/2 must be retenciones

Correct:

<?xml version="1.0" encoding="utf-8"?>
<cfdi:Comprobante xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:cfdi="http://www.sat.gob.mx/cfd/3" xsi:schemaLocation="http://www.sat.gob.mx/cfd/3 http://www.sat.gob.mx/sitio_internet/cfd/3/cfdv33.xsd"
  Version="3.3" Serie="ABC" Folio="0001" Fecha="2017-06-20T00:00:01"
  ...

❖ Date of the Receipt

• The value on the attribute Fecha of the element Comprobante cannot be larger than 72 natural hours.
• The date and time of issuing can be up to 5 minutes on the future at the moment of its validation.
• For the CFDI supporting Retentions and Payment Information, the technical standard states that the Stamping Date must match with the time zone of Mexico City (Mexico's Central time zone)

On Anexo 20's section F Additional Validations to be fulfilled by the supplier, SAT defines the following regarding the Fecha atribute of the Comprobante node of CFDI 3.3 and CFDI 4.0:

When receiving the XML file, the Certification Provider must verify that the date and time is not:

• Larger than the date and time increased in the deadline specified on the current Miscellaneous Fiscal Resolution - Suppliers' obligations on the CFDI certification process.
• Shorter than the date and time diminished in the deadline specified on the current Miscellaneous Fiscal Resolution – Suppliers' obligations on the CFDI certification process.

❖ Issuer

• The Issuer's RFC for the receipt must be published on the List of Taxpayers with Obligation (LCO) of the SAT.
• The seal of the receipt should not be generated with the e.firma's Digital Certificate (also know as FIEL) of the issuer.
• The Digital Stamp Certificate (CSD) of the issuer that was generated with the Digital Stamp of the Receipt:
  • Must be valid on the date of issuance of the receipt.
  • Must be on the List of Taxpayers with Obligation (LCO) published by the SAT.
  • Should not be revoked.
  • The serial number of the certificate must match the CSD number of the receipt according to base64 on the attribute Certificado.
  • The serial number of the certificate must match with the Issuer RFC of the receipt.
• You can obtain more information about the Digital Stamp Certificates on the SAT's portal for procedures and services. On that same portal, you can also find Digital Stamping archives to perform tests for your implementations.

❖ Issuer Stamp

• The attribute Sello of the CFDI is generated from the original chain that SAT has defined. Any alteration of the data conforming the original chain after generating the Sello will result on an invalid Stamp. You must consider that there's a sequence to generate the original chain: Cadena original CFDI ver 3.3 | Cadena original CFDI ver. 4.0 | Cadena original Retenciones ver. 1.0 | Cadena original Retenciones ver. 2.0
• Information on the Complementos and Complementos Concepto (Supplements and Supplements Concept) are part of the original chain.
• The Sello of the Fiscal Receipt must be done with the CSD of Issuer. This will be verified using the Base 64 Certificate listed on the Certificado attribute of the Receipt.
• The digestion algorithm for CFDI 3.3, 4.0 and Retenciones 2.0 is SHA2 256, and for Retenciones 1.0 is SHA1.

❖ Addenda

• Receipts can be received with or without an Addenda element. The Addenda has commercial information between the Issuer and the Receiver, so no type of validation is performed over this node. By SAT disposition the CFDI version sent to SAT has no Addenda.

Validations for CFDI 3.3

One of the most important changes for CFDI ver. 3.3 are the rules of validation that SAT has requested from the PCCFDI, they should be performed before the certification of each receipt. These rules of validation can be classified in the following way:

• Arithmetical
• Conditional
• Consistency

On this article you can find a list of scenarios that a PCCFDI must validate and if necessary, notify the error code.

Validations for CFDI 4.0

For CFDI, the rules of validation specified by the SAT for the CFDI on the Matrix of Error Codes for digital fiscal receipts on internet version 4.0 is being followed

On this article you can find a list of scenarios that a PCCFDI must validate and if necessary, notify the error code.

Method [TimbrarComprobante]

This Method of the web service is used to request stamping, this can be to certify (stamp) a Digital Fiscal Receipt on Internet (CFDI) or a CFDI that supports Retentions and Payment Information. The certification is made according to the definition on Anexo 20 of the Fiscal Code of the Federation published on the Diario Oficial and on SAT Portal.

Next, you can see the information of the request and of the response:
