Payment term between businesses
Between businesses, Act 3/2004 sets a payment term of 30 days. The parties can agree to extend it, up to a maximum of 60 days. Each year’s late-payment interest neither lengthens nor shortens that term, and this guide does not quote it.
30 days, and up to 60 if there is an agreement
The term is counted under the act, from receipt of the invoice or the moment the act points to. If there is no agreement, it is 30 days. An express agreement can take it up to 60, and not beyond. Putting a 90-day due date on the invoice does not create a legal term of 90. Late-payment interest is a different piece, published each year, and it does not replace these days.
- Legal term: 30 days.
- Agreement: up to 60 days, no more.
- The year’s late-payment interest is not the term.
The due date you write
In Factura Fácil you can record the due date on the invoice. The app does not impose 30 or 60 days, and it does not calculate the year’s late-payment interest on its own. The term you enter has to fit the act if both parties are businesses.
Common questions
Can we agree 90 days?
No. An agreement can extend the term up to 60 days. A longer due date is not the term in Act 3/2004.
What late-payment interest do I put?
This guide does not quote this year’s rate. The 30-day or 60-day term does not depend on that figure.
