When I get a PO, I want to view the PO and the quote side-by-side to make sure the PO has the right prices.
First close any documents already open in Adobe Acrobat. Then open up the PO and Quote .pdf’s in Adobe Acrobat, then go to the top menu, select Window, then Tile, then Vertically.
Then you can scroll each document independently to line them up vertically when they are side-by-side.
