New Invoicing - Allow us to have Negative quantities on invoice
In the Classic Invoicing, we could set a negative item amount which was useful to make it clear to clients that we had refunded something. It also corrected the stock levels in the inventory. In new Invoicing, you can set a negative financial amount but you are not allowed negative quantities, as such it is not clear and it messes up the stock inventory levels. You can do it via credit notes but this requires more things to be issued to clients etc.

The new Xero Invoicing system's restriction on negative quantities is a major inconvenience for users who previously relied on this feature in Classic Invoicing to clearly indicate refunds and automatically adjust stock levels. While negative financial amounts are still permitted, the inability to set negative quantities creates confusion and inaccurate inventory tracking, forcing users to resort to issuing separate credit notes—an unnecessarily complicated step. Restoring the option to input negative quantities would streamline workflows, enhance transparency for clients, and align with user expectations. Just as tools like Block Blast Solver https://blockblastsolverlive.com/ Live simplify gameplay with precision and flexibility, Xero should aim to simplify invoicing with intuitive features that users have come to rely on.

Agreed - it would be much better to be able to credit and charge clients on the same document. They like having less processing to do, and so do we. This would is a necessary change.

At the moment, because new invoicing won't allow negative quantities, I cannot make clear on an invoice that employees worked for 105 hours but I'm spotting the client 5. I can say that they worked for 100 hours at $200/hr and 5 hours at $0/hr, or I can say that they worked for 105 hours at $200/hr plus discount of 1 unit of -$1000 but I cannot say that they worked 105 at $200/hr minus 5 at $200/hr which would show the client better what the value of the income foregone is.
