Overview
Internal Only Add-Ons let you attach a merchandise item to a booking that is visible only to you and your staff internally — customers booking online will not see it. It builds on the existing online add-on functionality, giving operators a way to use add-ons without exposing them on the book site.
If you're new to merchandise add-ons in general, start with the Merchandise article, which covers how add-ons work in detail.
Why Add-Ons Are Useful
Add-ons serve two purposes:
Upselling — They let you offer a merchandise item alongside an activity. (For online add-ons, this happens during the customer's booking flow; for internal-only add-ons, your staff offer it during internal booking.)
Date attachment for revenue recognition — This is the key secondary benefit. Normally, when you sell a merchandise item on its own, the date of sale becomes the item's date — because merchandise doesn't have a schedule. When a merchandise item is sold as an add-on, it instead attaches to the appointment date of the activity it was sold with.
Why the date attachment matters: Because the add-on attaches to the activity's appointment date, your reporting stays accurate. And if a reservation with an add-on is cancelled, the merchandise add-on can be cancelled along with the appointment — so you don't end up with a merchandise item lingering in your reports attached to a cancelled booking.
Enabling Internal Only Add-Ons
Navigate to manage.singenuity.com and select Products in the top menu.
Click Merchandise and select the merchandise item you want to edit.
Scroll down to the Enable Online Add-On setting and turn it on.
Directly below it, you'll see the Internal Only toggle. Turn it on.
With Internal Only enabled, the item will function as an add-on for internal bookings (register app and web register) but will not appear to customers booking online.
Common Use Cases
Dinner cruises and meal add-ons — Attach a meal or beverage package to a cruise booking internally, keeping it tied to the cruise's date without listing it for online customers.
Staff-added extras — Any merchandise you want your team to be able to attach to an activity booking that customers shouldn't see or self-select online.
Accurate revenue recognition on bundled items — Use internal-only add-ons so bundled merchandise attaches to the activity's appointment date and cancels with the booking if the reservation is cancelled.
Conclusion
Internal Only Add-Ons give you the benefits of merchandise add-ons — upselling and appointment-date attachment for clean revenue recognition — while keeping the item hidden from online customers. It's a simple toggle that sits just beneath the Enable Online Add-On setting. For the full picture on merchandise and add-ons, see the Merchandise article.
