Service add-ons are extras for a booking, equipment rental or refreshments. Each one is a product, priced once per booking or per guest. The add-ons you had under Services → Addons are now products with the same name, price, tax group and images, and you edit them under Products.
The page for attaching add-ons to a service isn't reachable from the app yet, so nothing lets a customer or the register pick an add-on when booking a service. A package can still put one on a booking, see Components.
What to do instead
To charge for an extra on a booking today, add a product or an Open price line to the same cart at the register, or edit the order afterwards. See Selling at the counter.
Common questions
Is this the same as accommodation add-ons? Both are products. Accommodation add-ons are offered on an accommodation from its Addons page, and they can be included in every stay. See Add-ons.
