If your organisation has it set up, you can attach receipts to your expenses when you enter expenses as normal.
Once you've entered your expense:
Click the pencil
button next to the relevant expense.
In the dialog box which appears, either drag and drop your receipt file, or click the Drop files here to upload area, browse to the necessary file, and upload it.
Click Update.
Once you upload your receipt, you can download or delete it by clicking the needed icon.
📌 Note: You can upload multiple receipts to each expense, but file types must be one of the common file types such as PDF, JPG, or PNG.
You can't add receipts to mileage or automatically-calculated subsistence expenses.
