We have a team of 5 people working internationally. Everyone makes expenses using personal cash. Which we then reimburse.

I would like if you can tell me how I can create an expense tracker?

The features would be:

A user enters his expense claim (date of expense, description, Amount claimed, upload of a receipt image/pdf file)

After this an administrator will receive info  this via email and then approve or reject it

Your help is much appreciated

Kind regards
