Duplicates in the portfolio
Factura Fácil warns when the same invoice number and the same supplier match. The firm should look at that warning before the quarter. It is a warning, not a decision.
Number and supplier
The match does not say the second document is false. It says there is already an entry with that number and that supplier. Open it before you close the period.
- Same number and same supplier.
- Look before the quarter.
- A warning, not a decision.
The firm decides
It may be a double entry or two invoices the issuer numbered the same way. The warning deletes nothing. You keep the entry that fits. Portfolio access is on the gestoría page.
