I use Office Lens from my phone for free. Very easy. I also use my all-in-one printer to fax/scan as needed. Also, upload this to the cloud and share the document there. Many CPA/Bookkeeper types have secure upload software available from the web, which makes the apps even easier to use. Look into that.
Do the math and see if not having an app or a scanner is worth your time spent going to the FedEx office. Mine sure isn’t.
