It is worth defining a VAT column, at least on the payments heading side. Although you do not enter VAT using this column number (see below) it means that VAT prints as one of the columns in the Cash Book Reports where the columns are requested just like in a manual cash book.

On the payment side a fourth column type is allowed which can be used to post expenses to Job Costing.
