Door installers hang and replace interior doors, exterior entry doors, patio and sliding doors, storm doors, and garage man doors for homeowners, builders, property managers, and remodeling contractors. Invoices usually cover labor per door, the door and hardware if you supplied them, trim and finish work, and haul-away of the old unit.

Most door installers price per door, since a standard job has predictable steps. Interior slab or prehung doors are usually a flat fee per door, with a discount for multiple doors in the same visit. Exterior entry doors, sliding doors, and French doors are priced higher because of framing, flashing, sill work, and weight. Hourly rates ($50-100) are common for repairs, adjustments, and unknown conditions like rot or out-of-square frames. Doors and hardware you supply are billed at cost plus a markup, typically 15-30%. Extras such as new jamb extensions, lockset boring, painting or staining, and old door disposal are listed as separate lines. Builders and contractors often negotiate a per-door rate on volume and pay on net terms.

Notes: Payment due within 14 days. Doors supplied by customer; manufacturer warranty applies to the product. Installation labor is warranted for one year against defects in workmanship. Please call if any door sticks during seasonal changes and I will adjust it.
Listing 'master bedroom, 32x80, left-hand inswing' makes clear which door was done and helps with warranty claims or future service calls.
Separates your labor from product cost and makes clear who handles manufacturer warranty on defects or damage.
Shims, flashing tape, sealant, sill pans, and threshold parts add up, and clients and builders often want them shown.
Rot repair, out-of-square framing, or wall patching found after removal should be listed with the reason to avoid disputes.
Many states and cities require a license number on contracts and invoices, especially above a certain job value. Check your local rules.
Commercial and contractor clients often will not process payment without a PO, unit number, or job reference.
Stating the length and scope of your workmanship warranty sets expectations on sticking doors, gaps, and seal failures.
For retail homeowner jobs, many installers collect a deposit of 25-50% when the door is ordered, especially for custom or special-order doors that cannot be returned, with the balance due on completion. Small jobs under a few hundred dollars are often paid in full on the day of install. Builders and property managers typically pay on net 15 or net 30 terms, so state the terms on the invoice. A late fee of 1-1.5% per month is common if it is written in your agreement or on the quote. Accept checks, cards, and bank transfers, and consider requiring payment before leaving for new customers on larger jobs.
If you order the door, collect the full cost of the product or a large deposit before placing the order. Special-order doors are often non-returnable, and you do not want to be stuck with a custom size if the client backs out.
Quote a base price per door assuming a standard opening, then list rot, out-of-plumb framing, stucco or brick work, and trim changes as extras at an hourly or fixed add-on rate.
Old exterior doors are heavy and many dump facilities charge by weight. A flat disposal fee per door or per trip covers your time and fees.
Offer a lower per-door price when a client has four or more doors done in one visit. It wins the job and saves you setup and travel time, while still being profitable.
Take photos of flashing, sill pans, and the finished install before closing things up. If water problems appear later, photos protect you and support your invoice.
Use a flat per-door price for standard installs where conditions are known, and hourly for repairs, adjustments, and extra work found after the old door is removed. Many installers combine both on one invoice.
Yes. A markup of 15-30% is common to cover sourcing, pickup, handling, and the risk of returns or damage. Show the product as its own line item so the client can see what is labor and what is material.
Do not install it. Bill any trip or measuring time if it was not your error, and clarify in your quote who is responsible for verifying measurements and handedness. If you ordered it, you typically handle the return or claim with the supplier.
It depends on your state. Some states tax materials you sell, some tax labor on installations, and others tax neither in certain cases. Check with your state revenue department or an accountant, and show tax on a separate line when it applies.
Send a written reminder with the invoice and agreed terms, then follow up with a formal demand letter. Depending on your state and license, you may be able to file a mechanic's lien on larger jobs, and small claims court is an option for smaller amounts.
Send a Door Installer estimate for approval, then turn it into an invoice when the work is done.
