What’s a Reservable Product? 
️
A reservable product is tied directly to a booking.
-
Must link to a service (Like : Long Stay, Seminar).
-
Only sold with a reservation.
-
Rules & automation: add breakfast or packages automatically.
-
Flexible billing: once per stay, per person, per night… you choose.
-
Fixed price (no on-the-spot discounts).
-
Great for upselling — they show in the Booking Engine and pre-checkin emails.
Handy examples:
-
Breakfast (billed per person, per night—easy to automate alongside room rate)
-
Pet fee (per night)
-
Romantic package (champagne + chocolates, usually “once”)
-
️ City tax (per person, per night—watch those local regs!)

What’s an Additional Service? 
️
Extra flexible—sell with or without a reservation.
-
Custom price every time (discount that chocolate bar after 9 pm
).
-
Add to any customer bill, even walk-ins or guests without a hotel reservation.
-
Adjust billing date (default is “today”).
-
Not shown in Booking Engine by default, ideal for onsite or post-stay charges.
Typical uses:
-
🥤 Mini-bar items
- ️ Gift shop goodies
-
Smoking/cleaning fees
-
♂️ No-show or cancellation charges
-
Room damages or late charges

Top Takeaways
-
If you want the guest to buy it online or via the Booking Engine—and you want the price to stay fixed—use a bookable product.
-
For anything “on the fly,” flexible in price, or post-checkout, opt for an additional service.
-
Don’t forget: each product must be linked to an accounting category for reporting and compliance!
