A fiscal invoice carries more than a total.
The ERS guidelines set out the information a fiscal document must carry. The controller provides fiscal identifiers and verification data; the invoice must show the details required for its transaction type.
Supplier and location
The supplier's tax identity and the business-location information returned by the controller.
Buyer details for B2B
The buyer's TIN, name and physical address, with the document identified as B2B.
Items and tax
Item descriptions and codes, quantities and units, tax-exclusive unit prices, taxable amounts and the applicable tax labels. The invoice also shows its tax and total amounts.
Payment and document type
The payment method and whether the transaction is a sale, refund or another prescribed document type. Adjustments need the required reference and explanation.
Fiscal identifiers
The controller's invoice number, fiscal time and invoice counter.
Verification
A scannable QR code on the printed invoice, or the verification link for electronic delivery, as the guidelines prescribe.
