A window and door installer in Mandan, ND can carry supplier deposits with a line of credit sized to the jobs it has booked, and pay for a machine such as a vacuum glass lifter with construction equipment financing. This post follows three invented houses from the window order to the builder's payment. A funding partner sets any terms.
Special-order windows are paid for in two parts before the builder pays the installer. An invented three-house schedule shows how high the balance climbs, what a line draw costs, and how a glass lifter fits equipment financing.
Supplier Deposits on Special-Order Windows Before the First Payment
An installer who works for home builders orders windows and patio doors made to each house's sizes. A supplier may ask for half of a special order when it is placed and the rest when the units ship, weeks before the installer sends its own invoice. The builder then pays on its terms after the units are in.
That order of events is the gap: the installer pays for materials twice before it is paid once. Morton County had 100 new housing units authorized by building permits in 2025, and all 100 were in single-unit buildings (Census Building Permits Survey).
In the first invented job, the windows and doors cost $18,764: a deposit of $9,382 on day 0, the same again when the units ship on day 42, and the builder's payment on day 77 in this invented schedule.
A Credit Line Sized to the Job Pipeline
One house is manageable from the bank account. Three overlapping houses are where a line of credit helps, because the amount out on materials rises and falls as jobs start and get paid.
| House | Order | Deposit day | Ship day | Builder pays |
|---|---|---|---|---|
| First | $18,764 | 0 | 42 | 77 |
| Second | $15,980 | 21 | 63 | 98 |
| Third | $21,270 | 42 | 84 | 119 |
In this invented schedule, the materials paid for and not yet repaid peak at $45,379 from day 63 until the first builder payment arrives on day 77. A line request near that peak covers the deepest point; a limit sized to one house would run out by day 42 in the invented example.
If every deposit and every shipping payment were drawn from the line at a 13.41% annual rate, simple daily, and each builder payment cleared its own house's draws, the interest across the three invented houses would be $1,152.45. The first house alone accounts for $386.06 of that invented total.
Dates move. If the first builder paid one week late in this invented example, the $18,764 drawn for that house would cost another $48.26 at the same invented rate, and the next house's deposits would sit on top of it for longer. Asking each builder for its payment terms in writing, and tracking them job by job, keeps the line request close to what the schedule needs.
Each builder payment also carries the installer's labor and margin, not just the windows. Paying the house's draws first and keeping the rest in the account is what lets the line fall back toward zero between rounds of orders.
Construction Equipment Financing for a Vacuum Glass Lifter
Large patio doors and picture windows are heavy, and setting them by hand takes several workers. A battery-powered vacuum glass lifter on a small lifting frame lets two installers place a unit, and it works for years, which is the shape equipment financing is built around.
In this invented example, the lifter and frame cost $11,780. The invented lifter loan runs 36 months at an 11.18% annual rate: $386.67 each month, $13,920.12 across the term, and $2,140.12 in interest.
Keeping the lifter on its own agreement leaves the credit line open for deposits, so the line balance falls back as builders pay rather than carrying a machine for three years. The lifter also earns on jobs that never touch the line, such as replacement windows in houses that are already lived in. For gaps that are not tied to one job, a working capital loan is another route.
Job Files a Funding Partner May Ask an Installer For
A funding partner may ask how the deposits and the builder payments line up. These records show it:
- Signed install agreements or work orders from the builders, with the price for each house
- Supplier order confirmations showing each deposit and the amount due at shipping
- Business bank statements for recent months, showing builder payments as they arrive
- A list of booked jobs with expected order, shipping and install weeks
- The glass lifter quote, with the frame and battery charger listed
Together, these let a reviewer rebuild the schedule in the invented table: when money leaves for each house, when it comes back, and how many houses overlap. An installer that keeps a simple job sheet with those dates can update it each week and have the current version ready if a partner asks for it, so the amount asked for and the records behind it tell the same story.
