Materials delivered but not yet built in still have to be paid for, then recovered as the work is certified. Doing that from memory is how a contractor ends up paid twice for the same brick.
An advance floating loose in a spreadsheet is a number waiting to be forgotten. Linking it to the bill line it relates to is what makes recovery automatic instead of manual.
Once linked, QScope knows that when that line is certified, part of the money has already been paid.
You do not track it. As the linked line is valued in following certificates, the advance is drawn back automatically, and the certificate shows what is happening rather than hiding it inside a total.
No. A variation changes the works. An advance pays early for works already in the contract, because the materials are on site and the contractor has bought them. It does not change the contract sum.
It follows your contract. Many contracts do not retain against materials on site, since retention secures workmanship rather than delivery. Set it to suit the terms you are working under.
The advance stays outstanding and carries into the final account, where it is settled with everything else. Nothing disappears quietly.
Yes. It prints on your letterhead with the description, the quantity and rate breakdown, the VAT and the total, ready to issue.
Not your whole portfolio. One live job, one certificate. If it does not save you time the first time you use it, walk away and take your data with you.
