Can I delete or void an adjustment note?

I’ll help you get rid of the adjustment note, @queensofthedamne.

To clarify, are you referring to deleting the adjustment note itself or unapplying it from an invoice?

If you’d like to delete it, please follow the steps below:

1. Open the adjustment note.
2. Click More, then select Delete.

If you want to remove it from an invoice while keeping the adjustment note for that customer, follow the instructions below:

1. Open the adjustment note.
2. Select 1 payment link and then the date in the upper right corner.
3. Untick the Adjustment note in the Credits section.
4. Tap Save and close.

Once done, this adjustment note will be marked as Unapplied on your customer's Transaction List.
