When a customer is connected to HubSpot and Stax Bill, the cards in HubSpot will display information from Stax Bill. You can click an action to perform from cards or click the Stax Bill link to go to the equivalent page in the Stax Bill UI for additional information.
Invoices, Purchases (products), Subscriptions, Line items, and Customer cards are displayed on the right side. The cards can be moved to your preference. For more information, consult the HubSpot documentation.
