Create an invoice from within the app for self-employed sole traders or limited companies.
this would have my vote in preference to MTD assuming you can do both within the next 12 months
@steven heather: Hi Steven, thanks for the comment. We will definitely be doing both within the next 12 months and whichever we choose first is likely to be ready within a couple of months. FYI by clicking on the red triangle next to the heading "Create an invoice" you can upvote this idea.
@Tim Fouracre: looking forward to it. Would also be great if they could be personalised with individual business logos
