ServiceTitan is built for larger HVAC, plumbing, and electrical companies: dispatch, memberships, inventory, and business units. QuickBooks Online keeps the books. ServiceTitan sends its transactions to QuickBooks in exports, not a live two-way sync, and how you set up the mapping decides whether QuickBooks can tell you which part of the business makes money.

Five points. Each one is explained below.
The connection runs one way, from ServiceTitan into QuickBooks. It carries invoices, payments, and sales tax. ServiceTitan’s team turns the integration on, and an administrator connects it.
There are two ways it runs.
Customers are created in QuickBooks when their first invoice exports, matched by name. Payments land in Undeposited Funds until you record the bank deposit.
ServiceTitan’s own articles disagree on whether vendor bills and payments export in every setup. Confirm with ServiceTitan support for your account before relying on it.
Example: An HVAC and plumbing company has three business units: HVAC service, HVAC install, and plumbing. Each one maps to its own QuickBooks class. The QuickBooks profit and loss by class now shows that installs carry most of the revenue and service carries most of the margin. That shapes where the next technician goes.
Payments wait in Undeposited Funds. When the money reaches the bank, record the deposit in QuickBooks against those payments. Card deposits arrive net of processing fees, so the fee goes on its own line. Voids and refunds after a deposit also lower what hits the bank.
Example: On Monday, $12,500 of card payments export to QuickBooks. On Wednesday, $12,140 lands in the bank. A $150 refund came out of the batch, and $210 went to fees. The deposit matches the $12,500 of payments, less the $150 refund and $210 of fees.
ServiceTitan’s job costing reports work by job and by business unit, and they are the best place to price work. In QuickBooks, business units carry through only as classes on invoices and payments. Bills do not carry the class. So job costing inside QuickBooks is partial, and ServiceTitan should stay the source for job profit.
One rule from ServiceTitan matters here: edit technician hours in ServiceTitan, not in the payroll system. Otherwise job costing shows profit that is not real.
Yes, through Intuit’s Web Connector. Desktop does not take purchase orders. QuickBooks Online takes them, but every line comes over under one generic item. Inventory across several warehouses needs Desktop’s Advanced Inventory add-on.
We keep dispatch and job costing in ServiceTitan and the books in QuickBooks Online, and we close the gap between them every month.

In the standard setup, no. You batch, post, and export. The touchless option exports invoices, payments, and bills on its own within minutes.
As classes, once you create the classes in QuickBooks and assign each one to a business unit.
No. It builds a pay file for your payroll company. Payroll reaches QuickBooks through the payroll provider.
QuickBooks matches customers by exact name. A small difference, like a comma, creates a new customer. Rename the duplicate in QuickBooks.
Yes. ServiceTitan connects to your own QuickBooks account.
