On field Cash Collectors and Accountant Cash in Confirmation

Hello, first of all, I love Dolibarr
I wish to deploy cash collectors who will carryout printing receipts on the field for clients who pay.
Also, I will love that the cash collected by the agents on the field be confirmed by an accountant at the office upon return at the office.

I thought of a validation button but the button in Dolibarr doesn’t serve the same purpose.
How can I go about collecting cash on the field and validating cash in at office ?
Thanks
