What a window and door office manager keeps track of
Every job runs on a special order, an in-home contract and, on older homes, lead-safe paperwork. This role keeps each piece filed and checks that the bill matches what was installed.
Lead records go out with the final bill
For houses built before 1978, EPA's rule sets a deadline for handing over the lead-safe compliance records: with the final invoice or within 30 days of finishing, whichever is sooner. A tenant-occupied home also needs a copy for an adult living there. Put that step on the billing checklist so the packet leaves with the invoice. Source: eCFR: 40 CFR 745.86, Recordkeeping and reporting requirements (EPA lead renovation rule).
Old-house files stay three years
The same rule says the company keeps every record needed to show it followed the lead steps for three years after the job is done, and hands them to EPA if asked. That covers pamphlet receipts and the proof the lead-safe steps were done. Scan them into the job file and set the purge date from the completion date, not the sale date. Source: eCFR: 40 CFR 745.86, Recordkeeping and reporting requirements (EPA lead renovation rule).
Save the rating label before it's gone
The NFRC label on a new window lists its rated performance, such as U-factor, which measures how well it keeps heat from escaping a room. The sticker usually comes off at cleanup. Have crews photograph each one at install and add the photos to the job file, so the office can answer an energy question or back a warranty claim later. Source: National Fenestration Rating Council: What the NFRC label tells you.
Check the maker's confirmation against the contract
Read each maker's order confirmation line by line against the signed contract: sizes, inside and outside colors, grid pattern, glass package and which way each door swings. A mistake caught here costs an email. One caught on install day costs a remake, a second trip and an unhappy homeowner.
How much windows & doors office managers make
The closest BLS group for windows & doors office managers is First-Line supervisors of office and administrative support workers. First-Line supervisors of office and administrative support workers who work for building finishing contractors earned a median of $32.00 an hour ($66,560 a year) in May 2025, according to the Bureau of Labor Statistics.

About 5,310 of the 1,436,680 First-Line supervisors of office and administrative support workers in that survey work for building finishing contractors.
Window companies usually salary this role and pay the template's bonus on clean billing and office efficiency. Even the template's top figure is short of what BLS lists as typical pay for building finishing firms' office supervisors.

Windows & doors office manager interview questions
Two of the 6 questions we'd ask, and what a strong answer sounds like. Ask every candidate the same questions, and rate each answer on your own before you compare notes.
Situational · Final payment disputes
A homeowner won't make the final payment until a torn screen is replaced, and the crew says it was fine when they left. What do you do?
A strong answer: Thanks the customer, asks for photos, books the fix quickly, agrees on when payment is due once it's done, and logs it so the pattern is visible.
Behavioral · Fixing billing errors
Tell me about a time a billing error reached a customer, like a deposit or lender payment not applied. What did you do?
A strong answer: Owned it with the customer, corrected it fast, and changed a step, such as a second check before invoices go out.
The template's targets are samples. Clock your office's current pace for a month or two, then set the bar from there.
Billing Accuracy
Tally invoices sent with an error in price, change orders, tax or customer name, plus payments posted to the wrong job. Check a sample against the signed contract monthly.
Document Processing Turnaround
Time-stamp each document as it arrives, such as a signed contract, a maker confirmation or a completion form, and again when it's filed in the job record. Track the gap.
Office Workflow Efficiency
Pick the office tasks that hold up jobs, such as order entry, confirmations and final bills, and track how many were done on the day they were due.
Customer Inquiry Resolution
Log each question from homeowners, crews and makers, when it arrived and when it got an answer, and set your own turnaround by type.
Career path
Billing coordinatorHandles invoices and payment posting while learning the order flow.
Office managerOwns the billing desk, the job records and the office staff.
Operations managerTakes on crews and the warehouse as well as the office.
General managerRuns the branch's sales, installs and profit.
How much product knowledge does a window office manager need?
Enough to read an order. They should know the window styles you sell, the main glass and color options, how door swing and handing are written, and what a mulled unit is, so a confirmation that doesn't match the contract jumps out. A day riding with a crew and an hour in the warehouse teach most of it.
How much does a windows & doors office manager make?
First-Line supervisors of office and administrative support workers who work for building finishing contractors earned a median of $32.00 an hour ($66,560 a year) in May 2025, according to the Bureau of Labor Statistics. The middle half earned between $53,880 and $81,370 a year. Pay also depends on your local market, experience and overtime.
Should CSRs report to the office manager?
At a company this size it usually works best. Booking mistakes show up later in the office manager's files and billing, so one person owning the scripts, the call notes and the calendar rules closes the loop. Write down which calls go straight to the dispatcher, such as a crew running late, so the line between office and dispatch stays clear.
When install work slows in winter, what should the office manager tackle?
Clean up the season: close open jobs, chase small balances, purge files past their keep date, and go over the billing checklist with the bookkeeper. It's also the time to update forms, price sheets and the CSR scripts before spring calls pick up.
What hands-on work comes with the office side of a window company?
Carrying a file box or a case of paper up to 15 pounds, walking documents between desks, and using computers, printers and phones all day. Describe those duties in the posting so applicants can tell you if any would call for an accommodation.
