Hi champs2018, you would usually get all your credits at the End Panel stage - this is where your CSR will consolidate your Tender PA's and Selections from Kitchen and Tiling etc into one document. I too am expecting credit on some items.
The only way to get on top of it and to track it is by recording everything on a spreadsheet. I have pretty much transferred all the Items from Tender onto a spreadsheet and updated it along the way when i signed off on Quotes. This will allow you to keep track of everything, in my opinion.
