Can the process be totally paperless?

Other than printing the barcode labels, which will be on paper, if you intend to do it totally paperless then yes you can.  It depends on your process.  For example you may want to use barcode sheets containing the item barcode and location barcode rather than scanning the actual item or location barcode which could be damaged and difficult to scan.  Do you want to generate a variance report and check the items yourself knowing there won’t be too many and you don’t have access to the barcode terminal?  You may be more comfortable using paper in some cases as it’s the first time you are using software to do it.  It really depends on you but yes it can be totally paperless.
