Connecting ServiceTitan, Housecall Pro or Jobber to QuickBooks

You dispatch in ServiceTitan, or Housecall Pro, or Jobber. You invoice from it, take payment on it, and it syncs to QuickBooks. Two systems, one connection, and the assumption that the numbers agree.

They usually do not, and the gap is rarely where people look for it.

What the sync actually moves

Broadly, these integrations push invoices, payments, customers and sometimes items or inventory into your accounting file. What they generally do not do is reconcile anything. The sync is a data transfer, not a control.

That distinction is the whole article. A transfer that runs successfully every night can still leave you with two systems that disagree, because nothing is checking.

Where it goes wrong

Payment processing deposits. Your customer pays $1,000 on a card. The processor deposits $971 after fees. The field system records a $1,000 payment; the bank shows $971. Unless the $29 fee is booked, the accounts will not reconcile — and that gap repeats on every card transaction, every day.

This is by far the most common reconciliation problem in service businesses, and it compounds quietly.

Batched deposits. Processors often deposit several days of payments as one lump. Matching a single bank line to eleven invoices is not something a sync does for you.

Refunds and partial payments. These frequently sync incorrectly or not at all, leaving invoices showing as open when they were settled, or paid when they were refunded.

Duplicate customers. "Smith, John", "John Smith" and "J Smith" become three records, and receivables get spread across all three so nobody looks overdue.

Items mapped to the wrong accounts. A new service added in the field system maps to a default income account and disappears into a bucket. Your revenue split — install versus service, insurance versus retail — silently stops being accurate the moment someone adds a service type without checking the mapping.

Timing. Field system reports by service date, accounting by invoice or payment date. Month-end comparisons will differ, and both can be right.

What good reconciliation looks like

Every month, three checks:

Bank to books. The closing balance in accounting matches the bank statement exactly. Not approximately.

Processor to bank. Gross payments taken in the field system, minus fees, equals what actually landed. The fees are an expense and must be booked, not netted invisibly.

Field revenue to book revenue. Total revenue in the field system for the period agrees with the accounting file, with any timing difference explained rather than shrugged at.

If all three tie, you can trust both systems. If any does not, you are running on numbers that look precise and are not.

Getting the mapping right

Worth doing once, properly:

• Map service types to the income accounts that match your chart of accounts — install, service, agreements, insurance, retail
• Map material and part costs to cost of goods sold, not overhead
• Give processing fees their own expense account
• Set a rule that new service types get a mapping decision before they are used, not after

Miss that last one and your revenue split degrades gradually, which is worse than breaking outright because nobody notices.

Which software matters less than you think

ServiceTitan, Housecall Pro, Jobber, FieldEdge — they differ in features, and any of them can feed clean books. What decides whether your numbers are right is not the product. It is whether someone reconciles it monthly and owns the account mappings.

We work with all of them. The setup differs; the discipline does not.
