How to issue an invoice with IGI in Andorra
An Andorran invoice must include its series, each party’s required tax identifier, line-item detail, and the applicable IGI treatment. A missing required field may create problems later.
- Choose the customerWith their NRT and address saved, so they don't have to be typed in every time.AndCompta does it
- Add the linesChoose them from the catalogue, where the default price, ledger account, and IGI rate are already stored.AndCompta does it
- Check the IGI treatmentCheck each line. If an exemption or reverse charge applies, mark it explicitly.AndCompta does it
- Issue the invoiceThe next number in the series is assigned, the PDF becomes immutable, and the journal entry is generated.AndCompta does it
As is usually done
The usual approach is to copy last month's invoice, change the details, and hope nothing was missed. That works until a client needs different treatment or two people issue invoices at once and reuse a number.
With AndCompta
The client, catalogue, and series already exist in the system, so you assemble the invoice by selecting what applies. On issue, the number is unique, the PDF is preserved exactly as the client received it, and the journal entry is complete.
One nuance: You or your accounting adviser decide the IGI treatment for each transaction. The catalogue remembers the last selection, but it does not interpret the law for your specific case.
The modules involved
- Invoicing — Invoices and credit notes with IGI, numbering by series and immutable PDFs.
- Quotes and pro forma invoices — Commercial documents with separate numbering and controlled conversion into invoices.
