We generate a sales invoice when we complete the sales order that has:

Product price £1.00

Label price £0.50

Hand produced £2.00

Product price Total £3.50

We might add delivery / admin / certificate cost £0.50

Total product price £4.00

Volume x 100

Total invoice price £400

(ignore VAT just now)

How do we invoice just 100 x £4 (auto fill if possible) based on sales order quantity and not show all the lines of product/label/labour price.  The customer has been quoted £4.00
