I'm using Sole trader Online. How do I apply a credit note from a supplier without having to upgrade to a much more expensive plan

You can use a Bank deposit to record a credit note as money coming back in, essentially treating it as a refund from the supplier.

Here's the workflow:

1. Navigate to +Create and choose Bank deposit.
2. In the Add funds to this deposit section, set the Received From field to the supplier's name.
3. In the Account field, select the same expense category the original purchase was coded to (e.g., Office Supplies or Cost of Goods Sold).
4. Enter the credit note amount as a positive number.
5. Save and close after.

This effectively reduces the expense category balance, which is the closest accounting outcome possible without a dedicated Supplier Credit feature. Note that this won't link to a specific original expense, as there's no "apply against" functionality on this plan, but it keeps your books directionally correct.

Please keep in mind that this entry will not show as an open or unapplied credit against the supplier, and it won't offset a future payment. You'll need to manually track that you have a credit available to use next time you pay that supplier.

Let me know if you have any further questions.
