Re: mythbusters page
Yes, for phase 2, cut and paste went out the window, as did manually filling boxes in in, but I did find another link yesterday where HMRC stated that File-Save actions were fine and considered suitable "digital links" when moving data into bridging spreadsheets. Which is what I've been doing all along. I export as an XLS file from Sage 50, and import it into my suppliers web page by clicking "Upload" and locating the file on disk. The format of the XLS spreadsheet is pretty much 9 cells filled in with the VAT values.
I'll try and dig out that other link I found.
