HI @adnw,
For the digital copies it may be easiest to send them into your receipts hub via email. You would need to make sure that the files are in a format that are recognised the guide can be found here: The Receipt Hub
With the paper ones, there are a few scanner apps you can get or if you have an android device you can request to use the QuickFile app (it is still in testing stage at the moment - hence you’d need to request). Once you’ve got the photos you can then send these to the receipts hub or you can use dropbox?
It is all personal preference though so it would be hard to say which would work best for you.
Hope this helps?
