Thanks for the reply!

One more question,

for the stocktaking I need to scan barcodes and then add a number. Like a bottle of Jack Daniels with only half left I'd put 0,5 behind the barcode.

I want to do this in excel for starters. Is there a plugin, or option that I've missed that will put the first barcode I scan in a predetermined cell (like always start in B6) and then the next one under it, etc etc? Or anything like it?

I have no experience with programming but otherwise I'll have to give the API a shot.
