Yes, you'll need to sync your customers' data with HubSpot and QuickBooks Online (QBO) to successfully pull up the customer names, Bob. Let me guide how to achieve this and how to generate an invoice URL.

Ensuring that your customer's data is synced in the HubSpot app is crucial for the customer's name to be displayed on your invoices. It's advisable to import all customers from QuickBooks Online into HubSpot as contacts to ensure the customer's name is included.

To address your other concern, custom field mapping in the HubSpot app is required to connect QuickBooks invoice fields such as the link URL. This will enable the syncing of values between HubSpot and QuickBooks.

Since the syncing process and the mapping of custom fields must be done through the HubSpot app, I'd recommend reaching out to Hubspot support as they can provide better assistance with enabling this feature and adjusting its settings.
