To see the remaining amount on the protocol, you need to go to the Ebriza POS application.
After logging in, selecting a table, and marking the products you want to include on the protocol, you need to click on the 3 dots in the lower left corner.
This will open a window with the command options. Here you need to click on Move to protocol.
In the next window, you must select the user for whom you want to add this consumption to the protocol.
On the right side of the user, you will see the amount they have left on Protocol.
If you have not set a limit, then Unlimited will appear next to the user. If you have set a limit, you will see how much you have left/the total amount of credit.
