A customer is looking to add an output column on the invoices and change one of the current columns.

When generating an invoice PDF the five columns are -

• Description
• Qty
• Unity Cost
• Tax
• Currency ID eg GBP (this is line amount without tax)

They would like to have the columns -

• Description
• Qty
• Unity Cost
• Tax
• Tax Amount (value of the tax for the line item(s)
• Amount Inc VAT GBP (this is line amount with tax)

They would also like the "Sub Total" be changed to "Sub Total(ex VAT)"
