If a sales invoice has been raised and saved with a zero net value, this is not usually a system error. The most common causes are a missing price on the original order or an accidental entry of zero.
Common causes
The price (net value) field on the sales order was left empty when the order was saved. Financials allows an order to be saved with a quantity but no net price, and invoicing that order will generate a zero-value invoice.
The net price field was accidentally changed to zero during editing — for example, a typo or accidental keypress — before the order was saved.
What to check
Open the original sales order linked to the invoice.
Check the order lines: confirm whether a net price is entered for each line item.
If the price shows as zero or is blank on the order, the invoice will have saved with a zero value as a result.
What to do next
If this was a one-off data entry error: void the incorrect invoice, correct the price on the sales order, and re-raise the invoice.
If the price appears correct on the order but the invoice still saved with a zero value, or if this is happening repeatedly without a clear cause, contact the support team and provide the sales order reference and invoice number.
Note: If the same issue occurs again on future invoices with a correct price on the order, make a note of the exact sequence of steps taken before saving so the support team can investigate whether there is a reproducible system issue.
