Glossary

Cancellation reason (motivo de cancelación)#

The code the SAT requires when you cancel a CFDI: 01, 02, 03 or 04. See Cancellations.

CFDI#

Comprobante Fiscal Digital por Internet: Mexico's electronic invoice. Its current version is 4.0. A CFDI is an XML file sealed with the issuer's CSD and stamped by a PAC. See CFDI invoicing.

CFDI use (uso del CFDI)#

The code that says what the recipient will use the invoice for, for example G03 "Gastos en general" (general expenses) or S01 "Sin efectos fiscales" (no tax effects). It depends on the recipient's tax regime.

Constancia de Situación Fiscal#

The SAT document with your RFC, your name or business name (razón social), your tax regime and your tax address. It's abbreviated CSF. The details on an invoice must match it.

Credit note (CFDI de egreso)#

The CFDI de egreso, or nota de crédito: it documents a return, a discount or a rebate after an invoiced sale. See Credit notes.

CSD#

Certificado de Sello Digital: the certificate the SAT issues for sealing your CFDIs. It has a .cer file, a .key file and a password. It isn't the same as the e.firma. See Set up your issuer and CSD.

e.firma#

The SAT's advanced electronic signature (firma electrónica avanzada), formerly called FIEL. You use it to apply for your CSD and to sign the carta manifiesto. It isn't used to seal invoices.

Flex#

Mercado Envíos Flex: you deliver the packages for your sales yourself, in the areas where Mercado Libre offers the service. See Shipping.

Folio fiscal#

The UUID that the PAC assigns when it stamps a CFDI. It's the identifier the SAT uses. It isn't the same as the internal series and folio. See Series and folios.

Full#

Mercado Libre Full: your merchandise is stored in Mercado Libre's warehouses, and Mercado Libre ships each sale. Toldo never changes Full stock.

General public (público en general)#

Sales to customers who don't ask for an invoice in their own name. The CFDI uses the generic RFC XAXX010101000.

Global invoice (factura global)#

The CFDI that groups the sales to the general public that nobody invoiced in their own name, with one line item per sale. It's issued daily, weekly or monthly. See Global invoice.

GTIN#

Global Trade Item Number: a product's barcode number, with 8, 12, 13 or 14 digits. It includes EAN and UPC codes. Toldo uses it to link listings when there's no match by SKU.

Mercado Envíos#

Mercado Libre's logistics: Mercado Libre generates the label and the carrier delivers the package. It includes options such as Flex and Full.

PAC#

A provider authorized by the SAT to stamp CFDIs: it validates the invoice and assigns its folio fiscal. Toldo is not a PAC; it stamps through one.

Pack#

A Mercado Libre cart: several orders from the same buyer that ship together. Toldo imports it into Shopify as a single order.

Product or service code (ClaveProdServ)#

The ClaveProdServ from the SAT's c_ClaveProdServ catalog, which says what is sold in each line item of a CFDI. See SAT product codes.

RFC#

Registro Federal de Contribuyentes: the code the SAT uses to identify each taxpayer. It has 13 characters for individuals (personas físicas) and 12 for legal entities (personas morales).

Safety stock#

The units you don't list on Mercado Libre so you don't sell your last units twice. Also called a buffer. See Stock rules.

SKU#

The internal code you use to identify each product or variant. Toldo links your Mercado Libre listings to your Shopify variants by SKU. See Link listings.

Stamping (timbrado)#

The step in which a PAC validates a CFDI and assigns its folio fiscal. Without stamping, a CFDI isn't valid.

Tax regime (régimen fiscal)#

The category under which a taxpayer pays taxes, for example 601 "General de Ley Personas Morales" (general regime for legal entities), 612 "Personas Físicas con Actividades Empresariales y Profesionales" (individuals with business and professional activities) or 626 "Régimen Simplificado de Confianza" (simplified trust regime). It appears on your Constancia de Situación Fiscal.

Unit code (ClaveUnidad)#

The ClaveUnidad from the SAT's c_ClaveUnidad catalog, which says the unit something is sold in, for example H87 "Pieza" (piece) or E48 "Unidad de servicio" (unit of service).

User Products#

Mercado Libre's listing model in which one product can have several listings (for example, Clásica and Premium) that share stock.

Variant#

In Shopify, each version of a product, for example a size or a color. Each variant has its own SKU, barcode and inventory.
