Did you know that you can add negative values to your invoices in Sage 50?

Sage 50 Accounts


In Sage 50 Accounts v23 and above, you can add a negative value item line to invoices.

Special product codes

In Sage 50 Accounts, you can add a negative line by using the special product codes S1, S2 and S3. This allows you to also add negative lines to service invoices.

NOTE: The standard invoice layouts available with Sage 50 Accounts v23 automatically show the negative item lines. If you use a customised invoice layout, you can edit it to show negative item lines.

How do I add a negative line?

  1. Create an invoice as normal.

  2. Click the next available item line, then for a service invoice, enter some details and press F3.
    For a product invoice, click the arrow and double-click special product S1, S2 or S3.

  3. Click the Make negative checkbox.

  4. For the Unit Price, enter the amount as a positive value.

  5. Complete the item line details, then click OK.

  6. Enter any other items as required.

  7. Click Save, then click Close.

The value of the negative items shouldn’t exceed the total value of the positive items on the invoice. If you use the VAT Cash Accounting scheme, then the total value negative items for any tax code shouldn’t exceed the total value of that tax code.
