When Creating a customer in Stax Bill, you can link the new customer to an existing customer or company in HubSpot or create a new customer or company in HubSpot.
In Stax Bill, create a customer as you normally would on the Create Customer page. In the HubSpot section, select Create New Contact or New Company to create a new entity in HubSpot. Enter the entity's ID in the appropriate field to link to an existing entity. Click Save.
If a new contact or company is selected, that entity will appear in your HubSpot interface.
