Stamping - Primary Sector
(Agriculture, forestry, livestock and fishing)
The following document describes the stamping process established by Solución Factible® CFDI Issuance Service Provider through the acquirer of Goods or Services (PSECFDI) authorized by the SAT, which allows you to stamp electronic invoices if you are an acquirer of products from the Primary Sector (industrializer or marketer).

- Generate the primary sector query (local).
Note: If the stamping process is completed successfully, in addition to the Digital Tax Stamp, the digital tax receipt returned by the Webservice will have been stamped by Solución Factible®, so that the values of the attributes sello, certificado y noCertificado they will also be assigned by Solución Factible®. To ensure that the CFDI for the Primary Sector that you store are valid, consider using the CFDI that Solución Factible® returns, not just the Digital Tax Stamp.
