A Mexico invoice is more than a seller-created document. For tax purposes, Mexico uses the electronic Comprobante Fiscal Digital por Internet, or CFDI. SAT states that CFDI 4.0 has been the only valid version since April 1, 2023, so a downloadable invoice template should match the data you need before certification or accounting entry.
Use the invoice to organize the commercial details first: seller, buyer, line items, currency, payment terms, and taxes. The final tax invoice must follow SAT rules, CFF articles 29 and 29-A, and the Anexo 20 technical format. A basic PDF without CFDI fields is useful for review, but it is not a substitute for a valid electronic CFDI.
A Mexico invoice should identify the issuer with RFC, name or business name, fiscal regime, place of issue, and date of issue. The recipient data also matters. CFDI 4.0 uses RFC, recipient name, tax regime, fiscal domicile postal code, and CFDI use, so missing buyer data can stop the invoice from being accepted.
Each line should state the quantity, unit of measure, description, unit value, amount, and tax object. IVA must appear separately by rate where applicable, and Mexico's general IVA rate is 16%. Some transactions are zero-rated, exempt, or treated differently, so the tax object and tax line must match the actual transaction rather than a default.
Payment timing affects the CFDI fields. 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. Choosing the wrong code creates cleanup work later, especially when accounting records need to match collection timing.
Currency also belongs in the invoice data. CFDI uses the Moneda field from SAT's Anexo 20 structure, and TipoCambio applies when the invoice is issued in a currency other than Mexican pesos. A practical invoice download should make those details visible before the record moves into certification, accounting review, or client approval.
A free download is enough when you need one invoice draft, want to confirm client details, or need a document for internal review before CFDI issuance. It works best when the job is simple, the billable items are already known, and no team member needs to approve time or expenses.
A managed workflow becomes better when billable time, project costs, and invoice records need to stay connected. Everhour Reporting can group and filter project data, use 45+ columns, and export reports in CSV, Excel/XLSX, or PDF, giving billing teams a cleaner handoff before invoice creation and accounting review.

A downloaded invoice file is a working document unless it has been issued as a valid CFDI through the required SAT process. Mexico's tax invoice is an electronic CFDI with a folio fiscal and digital seals used for certification and verification. A normal PDF or spreadsheet can support review, but it does not replace the certified CFDI record.
CFDI 4.0 requires the recipient's RFC, name, tax regime, fiscal domicile postal code, and CFDI use. Collect these details before preparing the invoice, because buyer data errors can prevent the invoice from being issued correctly or force a cancellation and replacement process after the client reviews it.
IVA should appear in the tax section or line-level tax detail, depending on the invoice format, and transferred taxes must be shown separately by rate where applicable. Mexico's general IVA rate is 16%, but some transactions are zero-rated, exempt, or subject to special treatment, so the line's tax object must match the transaction.
Use PUE when the invoice is paid in full at issuance, together with the applicable payment-form catalog code. Use PPD with form 99 when payment is deferred or paid in installments. This choice should match the actual collection arrangement, because payment method fields affect the CFDI record.
A Mexico invoice can use a currency other than Mexican pesos when the transaction requires it. CFDI includes the Moneda field, and the TipoCambio field applies when the invoice is issued in a foreign currency. The invoice should show the currency clearly so the client, accounting team, and CFDI data stay aligned.
Everhour Reporting lets teams build reports with 45+ columns, grouping, filters, date ranges, and export formats such as CSV, Excel/XLSX, and PDF. Billing teams can use those reports to review billable work, costs, invoice status, and project details before preparing client invoice records.
Everhour marks time as invoiced after it is included in an invoice, so the same uninvoiced time does not appear again for future billing. That invoice workflow reduces duplicate billing risk when several projects, tasks, or people feed the same client account.
Use Everhour Reporting to group billable work, review project data, and export billing reports before invoice creation. Everhour gives billing teams cleaner inputs for client invoices and accounting handoff.
