I have just started using Quickbooks and need to set up the following type of invoice:

Materials total (supplied by us with VAT added - to be reported on our PL when payment/s are made)

Fitting (paid directly to a fitter with no VAT added, not CIS registered/self-employed - not to be reported on our PL as we don't receive this payment)

Total (for materials and fitting)

We also need to take a 50% deposit for the materials before we order them and then take the remaining 50% payment before we undertake the job, so I'd also like to know how best to take and handle these two payments and send a reminder to the customer for the last 50% if they have not paid).
