You can upload receipts in the following ways:
- Upload from your computer
- Take pictures with your smartphone
- Emailing receipts to your Envoice Invoice Inbox
Note: Emailing receipts to your Envoice Invoice Inbox, will make them available for users with Accountant user privileges. If you have no such privileges you can ask your accountant to forward receipts to your personal receipt wall.
