M, S1, S2 and S3 Special product / service codes in Sage 50

When to use the M, S1, S2 and S3 product codes

Within a product invoice there are 3 special product codes you can use which don’t appear
in the main list of products. These codes are M, S1 and S2 and can be used in the following
scenarios:

M – If you want to add a one-off message to your invoice which doesn’t have any value, you
can use M and then enter the required text. For example, ‘We’ll be closed for Christmas
between December 24th and 29th ‘

S1 – If you are selling a customer a product with VAT which you do not usually sell and
therefore is not in your product list, you can use the S1 code.

S2 - If you are selling a customer a product without VAT which you do not usually sell and
therefore is not in your product list, you can use the S2 code.

S3 – Is used to add service items to product invoices. This code is only available in Sage 50
