Where the margin went
The windows went in on time. The builder paid. Nobody made a mistake you could name. And the profit you planned still didn't show up. This is the habit that finds it - plus a real window and door order, quoted against actual, for you to run yourself.

Pricing isn't math you do once
Ask the owner of a window and door shop whether they know what they truly made on each job, and the honest answer is almost always no. "I know we're making money. My accountant's happy. But I couldn't tell you which jobs the profit came from, or what I should have made." If that's you, this page is for you.
The margin rarely disappears dramatically. It goes quietly: the order goes out on time, the install goes fine, and the profit still lands short of plan. Most owners treat pricing as math you do once, at the desk, before the job. That's the mistake. The number is only as honest as what you feed it, and what you feed it comes from the jobs you've already built. Pricing isn't a formula. It's a loop that runs through the whole job.
Most shops do step one and stop. The margin leaks out through the other three, too small to see until the bank balance does the costing for them. Here's what that looks like on a real window and door order.
Two orders. Same shop. Different money.
A 20-item order for a builder: ten aluminium windows, six sliding doors and four pairs of hinged doors, all powder coated, quoted at a 35% margin the honest way: cost ÷ 0.65. Every item has its own fab sheet: two dozen extrusion cuts, as many hardware and fixing lines, a run of gaskets and pile. Every one of those lines is a price that can move. Order #1 is already filled in below, the way the shop first quoted and built it - clear it out and run your own last job through it instead.

No single line here is big enough to notice on its own - a few extra hours on the bench, full bars bought for cut lengths, a hardware price list nobody updated, the gasket and screws nobody counted. That's what a quiet leak looks like.
Order #2: the same builder's next house, a different mix of windows and doors. Fifteen minutes reading order #1's numbers moved three lines - hours per item, hardware prices, an offcut allowance on the bars - and margin kept went from 27% to 34%. Same crew. Same shop rate. The only thing that changed was where the quote started.
Winning work at a lower margin while planning your year on a higher one is how a shop goes broke busy. Priced from the truth, you're choosing your margin instead of discovering it after the invoice.

Margin is the slice of the price you keep. Markup is what you add to your cost to get there. Keep 35% and you need to add 54% to your cost, not 35%, or you'll quietly undercharge every job.
