Use this page to prepare the details behind a Mexican customer invoice before you issue or validate the official document. In Mexico, a tax invoice is a Comprobante Fiscal Digital por Internet, or CFDI, and SAT states that CFDI version 4.0 has been the only valid version since April 1, 2023. The practical goal is a bill that matches the customer, service, tax, currency, and payment facts.
The page fits service businesses, consultants, agencies, and project teams that need invoice-ready billing data for Mexico. It helps you organize the fields that belong in the invoice record, spot missing recipient data, and separate commercial detail from fiscal detail. The official CFDI still follows SAT rules, including CFF articles 29 and 29-A and the Anexo 20 technical format.
A Mexican CFDI identifies both sides of the transaction with RFC-based fiscal data. The issuer section needs RFC, name or business name, tax regime, and the place and date of issuance. The recipient section needs RFC, recipient name, recipient tax regime, fiscal domicile postal code, and the fiscal use to be given to the invoice. Missing or mismatched recipient data blocks clean issuance.
Line items need enough detail to support the charge. A service line normally includes quantity, unit of measure, description, unit value, amount, and whether the concept is subject to tax. The valid invoice carries the folio assigned by SAT and digital seals used for certification and verification. A seller-created invoice number alone does not replace the certified folio fiscal.
Mexico uses Impuesto al Valor Agregado, or IVA, on invoices. CFF article 29-A requires transferred taxes to be shown separately by rate where applicable, along with any withheld taxes. The general IVA rate under Mexico's VAT law is 16%, while some transactions may be zero-rated, exempt, or subject to special treatment. The tax object and tax line must match the actual transaction.
Payment timing also changes the CFDI data. For income invoices, SAT requires payment method and payment form. Use PPD with form 99 when payment is deferred or paid in installments. Use PUE with the applicable payment-form catalog code when paid in full at issuance. For invoices issued outside Mexican pesos, the CFDI data model includes Moneda and TipoCambio when applicable.
A one-off tool is enough when you need to organize invoice details for one customer, check whether required fields are present, or prepare a draft for later CFDI issuance. It works best for occasional billing with simple lines, one currency, known tax treatment, and no need to reuse the same project data across future invoices or reports.
A managed workflow fits recurring client work, multi-person projects, and billing that depends on approved hours, expenses, rates, and project status. Everhour Reporting gives teams customizable reports with 45+ columns, grouping, filters, exports, scheduled email delivery, and profitability dashboards, so billable totals stay traceable before invoice creation and accounting handoff.

Yes. SAT's invoice format applies to invoices generated for acts or activities performed by individuals and legal entities. Mexican invoices use the electronic CFDI structure, with legal basis in CFF articles 29 and 29-A and technical rules in Anexo 20. CFDI 4.0 has been the only valid version since April 1, 2023.
Collect the recipient RFC, legal name, tax regime, fiscal domicile postal code, and CFDI use. CFDI 4.0 treats these as minimum recipient data. A common mistake is using a trade name or an outdated postal code, then finding that the invoice cannot be validated cleanly against the recipient's fiscal record.
IVA appears when the transaction is subject to transferred IVA. Mexico's general IVA rate is 16%, but some transactions are zero-rated, exempt, or subject to special treatment. The invoice should show transferred taxes separately by rate where applicable, plus any withheld taxes. The CFDI tax object must reflect the service or good being billed.
Use PUE with the applicable payment-form catalog code when the invoice is paid in full at issuance. Use PPD with form 99 when payment is deferred or made in installments. The choice should match the real collection arrangement, since payment method and payment form are required fields for income invoices.
Yes. CFDI uses SAT's Anexo 20 structure and catalogs, including the Moneda field. For an invoice issued in a currency other than Mexican pesos, the exchange-rate field, TipoCambio, is part of the CFDI data model when applicable. The commercial invoice amount and the fiscal currency data must stay consistent.
Everhour Reporting lets teams build billing reports with 45+ columns, filters, grouping, date ranges, and exports in CSV, Excel/XLSX, or PDF. A project lead can review billable time, non-billable time, costs, invoice status, and profitability before finance prepares the Mexican CFDI record.
Everhour Billing & Invoicing converts tracked billable time and expenses into invoices, with line-item grouping by project, task, person, date, or other breakdowns. Non-billable work stays excluded from billable totals, and exported invoice status can sync back from QuickBooks Online, Xero, or FreshBooks.
Use Everhour Reporting to review billable work, costs, invoice status, and project profitability before CFDI preparation, giving teams cleaner billing records and fewer invoice disputes.
