Before you start
Decide which service the option belongs to, its extra price and any duration adjustment.
Open the correct service
Go to Settings → Services. Under the relevant service, select Add an option. Edit an existing option using its name.
Describe the extra clearly
Enter the option’s details and price/time adjustments. Use wording that makes clear what is included and what is optional.
Save and preview the total
Save the option, then select the service and add-on from the booking page. Check the combined price and duration before selecting a time.
Check the final appointment
Make a fictional test booking. Compare the selected option and total in the review, confirmation and owner appointment details.
What success looks like
The client can understand the optional extra and the full time and price before confirming.
If it doesn’t work
Fewer times appear with the option
Extra duration needs a longer continuous opening. Check the combined visit and buffers, rather than shortening the service just to expose a slot.
I expected a separate service
Create a service if clients should book it on its own. An add-on is part of its parent service.
