I am sending you invoice no. [number] due on [date].
'Fattura' = fat-TOO-ra; double 't' gives a short, crisp first vowel.
Use when sending an invoice to a client. Always include the invoice number and due date in the email body, not just in the attachment.
'Fattura' is the Italian word for invoice. Including the invoice number and due date in the body of the email ensures the client cannot claim they missed the deadline. 'Scadenza' (deadline/due date) is the key word for payment terms.
In allegato la fattura relativa al servizio di marzo.
Attached is the invoice relating to the March service.
References the billing period rather than a number
La scadenza per il pagamento è il [data].
The payment deadline is [date].
Can be added as a follow-up sentence for emphasis
Le ricordiamo che la fattura n. [x] risulta ancora non saldata.
We remind you that invoice no. [x] remains unpaid.
Use for payment reminders
Italian invoices must meet strict legal requirements set by the Agenzia delle Entrate. Since 2019, 'fatturazione elettronica' (e-invoicing) is mandatory for B2B transactions. Paper invoices are largely obsolete.
