Negative Qty for invoice

Using my Dolibarr
1

Hello,

Looking for assistance for the following situation:
- invoice issued containing 5 products.
- payment is made.
- customer receives only 4 products.

I want to make another invoice, having the missing product 5 entered with negative value -> Product - Price - Qty(-1) in order to make the payment back to the customer for the missing product.
Whenever I want to enter a negative quantity, app says: Quantity for line into customer invoices can’t be negative, no matter what type of Invoice I select.

Please advise,
Thank you!

Hello,

I found a workaround for this.
By applying a 200% discount you can get the desired output: a negative value on an invoice.

Best regards,

Hi,

you can just set the following flag under ‘Other Setup’: FACTURE_ENABLE_NEGATIVE_LINES ► Allows to add negative lines to an invoice ► (v8.0.2+)
