Is it possible to adjust points/punches manually from my computer?

This is possible.

1) Please log in to the Trezoro back-office from your Clover dashboard.

2) From the menu on the left select "Customer Data".

3) Locate the customer account that you want to edit and click on it.

4) Press "Adjust Points and Punches".

5) Select "Add" or "Remove" (depending on what you want to do) next to the balance that you wish to adjust.

6) In the pop-up window add a comment for your records and the adjustment that you want to make(numbers only- you don't need to write + or - as you have already specified that).

7) Save. The adjustment you have made will appear in the table below.
