I've been playing around with a demo account but can't see a way to record a line item for a commission payment with either a fixed amount or %age of the product sales price.

For example, with an item sales price of £50,000 and a commission of 10% the total displays £55,000. What I'm looking to do is invoice for the commission amount whilst at the same time always clearly displaying both the product sales price and the relevant commission due.

Even using a workaround by adding a "discount" amount of (say) 10% leaves an invoice amount due of 90% of sales total, rather than just the required 10% of sales price.

Can this be done??
