How to Use HubSpot Integration With QuickBooks Online Easily 2026

Log into QuickBooks Online first and take stock of what's already there — the Business overview shows bank balances, profit and loss, and outstanding invoices in one glance. You don't need to change anything here before connecting HubSpot, but knowing your current invoice and customer counts gives you a baseline to check against once records start syncing in from HubSpot. This is also a good moment to make sure your customer list in QuickBooks doesn't already have duplicate entries, since the integration will try to match by name and duplicates on either side create messy matches.

Log into HubSpot and you'll land on its home dashboard, with meeting prep, marketing automation prompts, and open tasks laid out across the page. The left-hand navigation is organized into CRM, Marketing, Content, Sales, Revenue, Service, Data Management, Automation, and Reporting — the QuickBooks connection lives under the App Marketplace, reachable from Data Management or by searching "QuickBooks" directly in HubSpot's marketplace search. This is the opposite direction from most accounting integrations, where the connection usually starts on the accounting side.

Find the QuickBooks Online listing in HubSpot's App Marketplace and click through to connect it. HubSpot redirects you to Intuit's sign-in page to authorize access to your QuickBooks company — the same OAuth handoff QuickBooks uses for any third-party app, so your QuickBooks password never passes through HubSpot directly. Once authorized, sign back into HubSpot and you'll land on a confirmation modal.

A "QuickBooks Online is connected" modal appears once authorization succeeds, showing your connected QuickBooks company name and the email tied to the account, with a checkmark against "Connect QuickBooks Online" and a second step below it labeled "Set up sync" still unchecked. This two-step layout matters: being connected is not the same as being synced. Click Continue setup rather than closing the modal, since leaving it half-finished means HubSpot and QuickBooks are authorized to talk but nothing is actually flowing between them yet.

The sync setup walks you through which objects move between the two systems — typically contacts, companies, products, and invoices — and in which direction. Decide early whether HubSpot or QuickBooks should be the source of truth for customer records, because syncing both ways without a clear priority leads to fields silently overwriting each other. Most teams sync contacts and deals from HubSpot into QuickBooks as customers and invoices, while letting payment status flow back from QuickBooks into HubSpot so sales can see who's actually paid.

Once sync setup finishes, give it time to run its first pass and then check both systems rather than assuming it worked. In QuickBooks, look for new or updated customers matching your HubSpot contacts; in HubSpot, check that invoice status or payment fields are populating on the relevant deal records. If a contact doesn't match cleanly — a typo in a company name, or a contact that exists in one system but not the other — the sync usually flags it for manual review instead of guessing, so check the integration's error or sync-log view for anything sitting unresolved.
