Jobs look profitable
until materials, labor, and other costs are fully accounted for.

Most small contractors stay busy, but don’t know which jobs actually make money.

The problem
What’s actually hurting contractor cash flow?
A full schedule doesn’t always mean a profitable business. Without clear job costing, it’s easy to miss where the money is going.
Labor runs over budget
and the extra hours quietly eat into your margin.
Change orders and added costs get missed
leaving you to absorb expenses that should have been billed.
One or two bad jobs
can wipe out the profit from several good ones.

What clarity actually looks like
Imagine opening QuickBooks and already knowing:
- Which jobs actually made money.
- Which customers are your most profitable.
- Whether you can afford to hire another employee.
- That payroll, taxes, and supplier invoices are already accounted for.
- How much you can safely pay yourself this month.
- Whether this month was actually profitable — not just busy.
Why Northstone
Bookkeeping should answer real business questions.
Good bookkeeping isn't just about keeping transactions organized. Your numbers should help you understand what's happening in your business.
Northstone focuses on the questions contractors actually need answered:
01Which jobs are making money?
02Where is our cash going?
03Are labor costs getting out of control?
04Can we afford to hire?
05Are we charging enough?
06Is the business actually becoming more profitable?
Your books shouldn't just tell you what happened. They should help you decide what happens next.
