wgSimpleAcc offers the possibility that files kann be uploaded directly to wgSimpleAcc. In order to enable this feature you have to install a ftp-app and you have to set the access data.
Select a FTP-Fileupload-App for your device, e.g. via Google Play Store. I use "Project Camera Upload"
Allow that the app gets access to images/media.
Open on top right 
the settings
For access in my app I need following settings:
Default Destination: FTP
FTP-Username: your_username
FTP-Passwort: your_pwd
FTP-Server: your_server
FTP-Port: your_port
- Start App „Project Camera“
- Click on camera symbol
- Take a photo of the bill/document
- Close camera
- In the app „Project Camera“ click on „Save“ and upload starts
- On wgSimpleAcc you can start adding the file to the transaction you want by clicking on "+"
- The form for uploading or adding a file to your transaction opens
- Click on „Uploaded files“
If you click on an item of the list "Uploaded files" you get a preview of the image. - Click on „Submit“
- The image is now attached to your transaction
- If you go back to transaction list you see now a yellow badge with 1
This means that one attachment is available for this transaction.
