Hi Lucian1,
Thank you for bringing your concern to our attention. I apologize for any delay in our response.
I understand the significance of accurately recording all transactions in your file. The deduction can be recorded as a credit for the customer. This credit can then be applied to an existing invoice, effectively reducing the outstanding balance. I recommend going through this article, 'Customer returns, credits and refunds'. It provides a comprehensive guide to creating credit for the customer.
Please feel free to reach out if you need further assistance.
