Job costing
See what every job earned.
Service calls, installs, and maintenance visits don’t earn the same. Job costing in QuickBooks Online keeps each job’s invoice, parts, and technician time together, so you can see which kinds of work pay best and which only keep the crew busy.
We set it up as part of your monthly bookkeeping, with every account reconciled against your bank and card statements each month.
What matters in your books
Built around how a service company runs.
Trucks and parts
Every truck carries parts, fuel, insurance, and often a loan payment. Recorded the same way every month, they show what it really costs to keep a truck on the road.
Technicians on payroll
For most service companies, payroll is the biggest cost. When it lands in the right accounts each pay period, the profit you see is real.
The heating season
The heating season runs from fall through winter. Books kept current through the rush show whether the busy months are carrying the slower ones.
Customers who pay later
Condo associations and property managers often pay on terms. A monthly look at who owes you, and for how long, keeps the money coming in.
How it works
Set up right. Kept right every month.
First we rebuild your books around how your company earns and spends. Then, every month, we record and reconcile every transaction, keep each category accurate as your work changes, and go over the numbers with you.
Talk it through

Set it up right
We clean up the file, split your income by type of work, separate materials and labor from overhead, and set bank rules so each charge lands in the right place.
Every month
Every transaction recorded and checked, every account reconciled, and a review of the month with you: which work paid, what materials and labor cost, and what to watch next.

We clean up the file first, going back as far as necessary. Then we split your income by type of work, such as installs, service calls, and maintenance, separate materials and labor from overhead, and connect bank feeds with rules so each charge lands in the right place. From then on, we keep it accurate every month and go over the numbers with you.
Yes. Job costing tracks the income and costs of each job separately, as a project or a sub-customer in QuickBooks Online, so you can see which jobs make money. Not sure how your file is set up? A QuickBooks Evaluation reviews it and ends with a one-hour call on what we found.
Yes. Monthly bookkeeping is done in QuickBooks Online. If you’re on QuickBooks Desktop, a QuickBooks Conversion handles the migration first, with your records checked before, during, and after.
Yes. A cleanup goes back as far as necessary, sometimes only to the last tax return, and then monthly bookkeeping keeps the books current from there.
No. We’re based in Hanover and work entirely online. Documents are shared digitally, and questions are handled by phone or email, so nobody leaves a job site.
It depends on your books: the volume, the complexity, and what you need. After a free consultation, you get a recommendation and a quote before any work begins. How pricing works.
