When I do purchasing for my ecommerce business I keep a spreadsheet in one screen and a browser in the other. Occationally I do from my laptop with one screen and it takes longer and I make more mistakes because the spreadsheet is huge and there is too much cognitive overhead when I have to keep flipping between windows/virtual desktops. Also when coding. I keep docs and messaging apps on one screen and I can keep the other screen clean with only code. It really is faster and easier with two screens.
