The fastest way to get paid on window and door work is to collect a substantial deposit before ordering the custom units, bill larger jobs in draws, and take the balance at the completion walkthrough while the new installs are right in front of the customer. Because windows and doors are custom, non-returnable orders, the deposit is your protection: installers who structure billing around the material order almost never get stuck financing a project. This guide covers the invoicing structure that fits measure-order-install work.
Key takeaways
- Collect a deposit of 30 to 50 percent to fund custom, non-returnable window and door orders.
- Bill multi-unit or whole-home jobs in draws tied to order and install phases.
- Take the balance at the completion walkthrough while the customer sees the finished work.
- Match invoices to the signed order (sizes, models, quantities) to prevent disputes.
- Digital invoices with a pay-now link get paid faster than mailed paper.
Why is the deposit so important for window and door jobs?
Windows and doors are made to order. Once you place the order with the manufacturer, that unit is cut to a specific size and finish and cannot be returned. If a customer backs out after you order, you eat the cost. That is why the deposit on window and door work runs higher than most trades: 30 to 50 percent at signing, enough to cover the manufacturer order. On a $14,000 whole-home window replacement, a deposit of $4,200 to $7,000 covers the material commitment before you place the order.
Tie the deposit directly to placing the order so it reads as fair: the customer is funding their own custom units, not paying for nothing. Check your state rules, since some cap residential deposits.
How should you structure progress billing?
Small jobs, a single door or a couple of windows, bill in two parts: deposit and balance at completion. Larger, multi-unit jobs should bill in draws tied to real phases:
- Deposit at signing (30 to 50 percent) to place the custom order
- Progress draw when the units arrive and installation begins, or when a defined phase (for example, all main-floor windows) is complete
- Final payment at the completion walkthrough and punch-list sign-off
On a $14,000 job, a structure of $5,000 down, $5,000 when units arrive and install starts, and $4,000 at completion keeps your cash in step with your costs. Each draw gets its own dated invoice.
How do you prevent disputes on custom orders?
Nearly every window and door dispute comes from a mismatch between what the customer expected and what was ordered. Your invoice and signed order should spell out exactly what is included: unit sizes, product line and model, frame material and color, glass package (for example, low-E, double or triple pane), grid pattern, and hardware finish. Anything the customer changes after signing, a color switch, an upgraded glass package, an added transom, becomes a written change order with its own price and approval before you reorder.
Because these are custom orders with lead times, confirm every measurement and selection in writing before the order goes in. A signed order plus signed change orders turns a five-figure disagreement into a simple reconciliation.
How do you get paid faster on every job?
- Collect the deposit before ordering so you never finance a custom order.
- Bill each draw the day the milestone is reached to keep cash flowing.
- Take the balance at the walkthrough with a digital pay-now link, not days later.

What does a whole-home draw schedule look like in dollars?
Numbers make the structure easy to run. Take a $14,000 whole-home window replacement of ten units. A clean schedule is a $5,600 deposit (40 percent) tied to placing the manufacturer order, a $5,600 progress draw when the units arrive and installation begins, and the final $2,800 at the completion walkthrough and punch-list sign-off. The heavy deposit lands where your risk is highest, at the moment you commit to custom units that cannot be returned, so you never finance the manufacturer order out of your own pocket. Each draw is its own dated invoice, and the deposit invoice should list every unit precisely (size, product line, frame color, glass package, grid, hardware) so the order and the invoice match exactly. On a small job, a single entry door or two windows, skip the middle draw: take a 40 percent deposit to place the order and collect the balance at the walkthrough.
How do you run the pre-order confirmation so nothing gets reordered?
The most expensive mistake in window and door work is a wrong custom order, so build a confirmation step before anything goes to the manufacturer. Sit with the customer and read back every selection: "Ten double-hung units, white exterior and interior, low-E double-pane glass, colonial grid, satin nickel hardware, this is what I am ordering, please confirm." Get that confirmation in writing before the order goes in, because once the units are cut to size they are yours if they are wrong. If the customer changes anything after signing, an upgraded glass package, a color switch, an added transom, it becomes a written change order with its own price and approval before you reorder, and the deposit on that changed unit rises to cover the new commitment. A signed order plus signed change orders turns a potential five-figure disagreement into a simple reconciliation. Keeping the order, change orders, arrival photos, and each draw invoice on one job, the way connected quoting and invoicing does, means the balance is ready to collect the moment the walkthrough is signed.
What are the most common invoicing mistakes on window and door jobs?
A few errors expose installers on custom, non-returnable orders. The first is taking too small a deposit, or none, then financing the manufacturer order yourself and eating the cost if the customer backs out; take 30 to 50 percent tied to placing the order. The second is billing a whole-home job as one lump sum at the end instead of draws tied to order, arrival, and completion, which strains your cash across a multi-week lead time. The third is placing the order without a written, read-back confirmation of every selection, so a wrong color or glass package becomes a reorder you cannot return. The fourth is treating a mid-job change casually instead of writing a change order with its own price and a raised deposit before you reorder. Handle those four, match every invoice to the signed order line for line, and a five-figure window job collects cleanly with the balance ready at the walkthrough.
