What changed with version 4.4 of the electronic invoice?
Version 4.4 is the current electronic document format from Costa Rica's Ministry of Finance (Hacienda), mandatory since 2025. It adds the electronic payment receipt to record installments on credit sales, expands the recognized payment methods, including SINPE Móvil, and adjusts identification and line detail fields. A system ready for 4.4 validates those fields before sending, which is why rejections go down.
