Separate cost from price
Labour, materials, subcontractors, hire, waste, and access need to be visible before the client sees the final number.
Choose markup or gross margin
Markup adds profit on top of cost. Gross margin shows profit as a share of the final selling price. Mixing them up quietly loses money.
Track the live job after acceptance
The calculator checks the quote. QuoteBuild keeps actual spend tied to the original estimate once work starts.

Quick answers.
What is a good construction margin?
It depends on job type, risk, overhead, and how busy you are. The key is setting the margin deliberately instead of hoping it survives the job.
Is markup the same as margin?
No. Markup is added to cost. Gross margin is profit as a percentage of the selling price. A 20% markup is not a 20% gross margin.
