Meaning
Standardized XML formats, known as Comprobante Fiscal Digital por Internet, are the only legal way to document sales and payroll in Mexico. Every sat cfdi must be validated by an authorized provider before it is sent to the customer or the employee. This system gives the Mexican government visibility into the movement of capital through the formal economy.
Digital Signature
Encryption protocols ensure that the document was issued by the person claiming to be the supplier and that it has not been altered. A valid sat cfdi contains a unique seal that proves its authenticity in court or during an audit. This security feature prevents the use of forged invoices.
Authorized certification providers act as the bridge between the taxpayer and the central tax database.
Fiscal Timestamp
External verification services add a precise time and date to every document once it passes the government checks. The presence of this mark on a sat cfdi confirms that the transaction was reported to the authorities in the correct tax period.
Reconciliation Efficiency
Taxpayers can download their entire history of issued and received documents directly from the government portal. Using sat cfdi data for accounting reduces the time spent on manual bank reconciliations.
