Update add-ons after a client books

To add an additional add-on from the group booking page after the client has already completed their booking, head to the Group status tab, and click on the three dots to edit the particular booking:

Here you can select and add the specific add-on your client wants to purchase for their booking:

Once you've updated the selection, you can review the changes that will be made to the invoice and click Save:

After the changes have been saved, the associated invoice will automatically update to reflect the new pricing and your group inventory will reflect the new available amount!
