To be able to allocate job request to your franchisee through the online booking form then you must have Online Booking addon enabled first.
Please refer to this article link that explains how you can activate and use the online booking form add-on.
Once the Online Booking add-on has been activated and configured then customers can now submit booking or job request through your online booking link.
When the enquiry is received from the online booking form it can be automatically routed to correct franchisee or manually allocated.
For Franchise Enterprise, enquiry will appear in the call center where you can manually choose an allocated franchisee, or close/delete the enquiry. Here's how you can acess it:
From the Dashboard, click Call Center
In the Call Center booking management shows online booking enquiry.
Enabling the head office's online booking form add-on will direct booking request into the call center booking window or allocate to closest franchisee and skipping the ServiceM8 Inbox of that account.
Note: You can change how the online booking be assigned to franchisee by going to Setting> Preferences> Enquiry Management.
