Stone, tile, and joinery can look right in the shop and still clash once Amman’s hard daylight hits, so the job starts with control and ends with a bill that matches what got agreed. This invoice gives a client one place to see what’s being charged, what the total comes to, and when payment is due.
The layout keeps the numbers upfront in Line items, then drops the payment wording underneath, so the client reads the charges before they get to the reminder about timing and late payment. The page uses a green-blue and olive accent with Raleway headings over Roboto body text, which keeps the invoice feeling like a site document, not a mood board.
- Line items Replace the placeholder entry with your own billed lines and prices so the client can see what each charge covers.
- Payment terms The written section states payment is due within 14 days, and it notes that late payment can pause work and add a late charge until the balance clears.
- Totals The totals block calculates what’s due from the line items so the client can read the final amount in one place.
Once the details are in place, you send the invoice to the client, and the same totals and terms travel with it so the amount due and the 14‑day window stay clear at the point they’re deciding how to pay.

Questions about this invoice template
What should an interior design invoice include?
An interior design invoice typically includes the billed line items, the total amount due, and payment terms that say when payment is due. This template includes line items, a totals block, and written terms that set a 14-day window.
How long should you give a client to pay an invoice for design work?
Many studios set a clear due window so the site schedule doesn’t drift while payment stays uncertain. The terms in this invoice ask the client to settle within 14 days of the invoice date.
Can an interior designer charge a late fee on an overdue invoice?
Late fees depend on what you put in writing and what local rules allow. The payment terms in this template say late payment may suspend further work and add a small late charge until the outstanding balance is cleared.
Can you stop work if a client hasn’t paid the invoice?
Studios often tie progress on site to keeping accounts up to date, because trades and materials keep moving either way. The written terms in this invoice say further work may be suspended if payment is late.
Do you need to itemize materials and services on an interior design invoice?
Itemization helps a client understand what they’re paying for and reduces back-and-forth when multiple purchases and trades are involved. The line items section is where you list each billed charge separately.
Can a client pay an invoice online?
Online payment depends on whether a payment method is connected on your side. The template notes you’ll need a payment method connected if you want the invoice paid online.
