Yes, add-ons are now available!
For the uninitiated, add-ons are additional services that your seller can provide at an additional cost on top of the main service (e.g. a hair wash on top of a haircut).
Here is a step-by-step guide on how to add these additional add-ons to your listing:
1. Simply click on "Your Services" in the merchant's portal. Then, click on the edit button on the specific listing that you want to add the add-ons to.
2. Scroll down and click on "Additional Services / Details".
3. Insert the title and surcharge of the add-on and finally click "Add".
