Gross profit shows if your work is profitable; net profit shows if your business is. Learn the difference, calculations, and what margins mean.
Gross profit is revenue minus the direct costs of delivering the work—materials, contractors tied to the job, payment processing fees on that sale, and similar direct costs.
Formula idea: Gross profit = Revenue − Cost of goods/services sold. Gross margin = Gross profit ÷ Revenue.
If gross profit is weak, no amount of careful overhead management will save the business. Pricing and delivery cost come first.
Net profit is what remains after operating expenses, software, rent, insurance, marketing, administrative time, and other overhead.
You can have healthy gross margins on projects and still lose money overall if overhead is high or utilization is low.
Net profit answers: after running the whole business, did we actually keep anything?
You invoice $8,000 for a project. Direct contractors cost $2,000. Gross profit = $6,000 (75% gross margin).
That month you also pay $1,500 software/rent allocation, $500 marketing, and $2,000 owner draw is separate—but operating expenses of $3,000 leave $3,000 contribution before tax/owner pay modeling depending on structure.
The point: celebrate project margins, then check whether the business overhead still fits. Both views matter for pricing decisions.
If invoices ignore true direct costs (including your subcontractors), you may think a job is profitable when gross margin is thin.
Raise prices or cut delivery cost when gross margins shrink. Cut overhead or increase volume when gross is fine but net is not.
Track a few representative jobs each quarter. Guessing margins leads to busy-but-broke cycles.
Pick your last three completed projects and estimate gross profit simply. Then glance at monthly overhead.
Set a target gross margin for new work (for example 50–70% for many service businesses, depending on model).
