Architettura di Base e Formula Matematica
Invoice Total = Sum(Line Items) + Applicable Taxes — Discounts
A legally compliant invoice must always include a unique sequential invoice number, the date of issue, payment terms (e.g., Net 30), and clear itemized descriptions of the work performed.
Migliori Pratiche e Linee Guida Essenziali
- Assign Sequential Invoice Numbers: Never use random numbers for invoices. Tax authorities require invoices to follow a strict sequential logic (like INV-2024-001) to prevent accounting gaps or fraud.
- Specify Clear Payment Terms: Do not just write 'Due upon receipt'. Use standard accounting terms like 'Net 15' or 'Net 30' to legally establish the exact date late fees can be applied.
- Save as Flattened PDF: Always export invoices as PDF files rather than Word documents. PDFs freeze the typography and layout, preventing clients from accidentally (or maliciously) altering the invoice total before payment.
Domande Frequenti (FAQ)
What is a Pro Forma invoice?
A Pro Forma invoice is essentially a preliminary bill of sale sent to a buyer in advance of a shipment or delivery of goods. It provides an exact estimate but is not a true demand for payment.
Is it safe to put my bank details on the invoice?
Yes. In fact, providing your direct IBAN and SWIFT/BIC codes directly on the invoice is standard practice for international B2B transactions to facilitate frictionless wire transfers.
Can I edit the PDF after it is generated?
No. For security purposes, this tool generates a flattened PDF. If you need to make a correction, you must update the fields in the web interface and generate a fresh file.
