Free Interior Design Invoice Template
An interior design invoice covers line items, a totals section, and payment terms that say when payment is due and what happens if it’s late.
A layout looks right on a rendering, then the contractor opens a wall and the real conditions show up. Drawings get revised, permits get reworked, and the budget needs to stay explainable to a landlord or reviewer while the scope keeps moving. This interior design invoice gives the client a clear bill for design work without rebuilding the wording every time.
The invoice keeps the pricing up front in Line items, then follows with the payment terms in Payment is due 14 days from… so the due date and the pause-on-late-payment rule don’t get buried. Headings use Zilla Slab with Roboto body text, with muted olive and a near-neutral rose accent, so the page reads more like a project memo than a marketing piece.
- Line items Replace the placeholder line with your own services and prices before you send it.
- Payment is due 14 days from… States the 14-day due date, plus what happens if payment doesn’t arrive on time.
- Totals Shows the final amount due in a dedicated totals block.
- Thanks for trusting me with your permit-ready plans. Closes the invoice with a short sign-off line the client sees after the numbers and terms are clear to them first.

What this invoice contains
1) Line items
Holds the billable services and the price you’re charging. The template ships with a placeholder line, so the real work is replacing it with your own description and amount.
2) Payment is due 14 days from…
Spells out the due date and the late-payment response: pausing work, notifying the client, and possible late charges or rescheduled site-work charges. Keep this section aligned with how you actually run payment follow-ups.
3) Totals
Calculates and displays the final amount due in one place. Check the total before sending so the client sees the same number you’re expecting to be paid.
4) Thanks for trusting me with your permit-ready plans.
Ends the invoice with a short closing line after the totals and terms. Leave the sign-off as-is or adjust it to match the project phase you’re billing for.
Who it is for
Interior designers billing for commercial interiors, residential design, or styling & staging work when the project needs a clean invoice the client can approve and pay against.

Questions about this invoice
What should an interior design invoice include?
An interior design invoice typically lists the services as line items, shows a total amount due, and states payment terms like the due date. This template includes line items, a totals block, and written payment terms.
How do you write payment terms for interior design work?
Payment terms usually state when payment is due and what happens if payment is late. The included terms set payment due 14 days from the invoice date and explain that work may pause with possible late or rescheduling charges.
Is 14 days a normal payment window for an invoice?
Fourteen days is a common net term for service invoices, but the right window depends on how you run billing and cash flow. This invoice already states a 14-day due date, so you’d only change it if your terms differ.
What do you do if a client doesn’t pay an interior design invoice on time?
A typical approach is to notify the client, pause work, and apply late charges if your terms allow it. The payment terms in this invoice spell out that exact sequence so the expectation is in writing.
Do you need to list materials and site work on the invoice line items?
The line items should match what you’re billing for, whether that’s design services, site visits, or reimbursable charges. This template ships with a placeholder line, so you replace it with the exact services and prices for the job.
Can clients pay an invoice online from this template?
Online payment is available if a payment method is connected in your workspace. Without a connected payment method, the invoice still works as a bill with totals and written payment terms.
