Essential Elements of an Interior Design Invoice Template

When creating your interior design invoice template, you want to make sure all the details are clear and easy to understand for your clients. At the same time, it's important to have all business-related information in place to help you keep your accounting records organized. For flawless invoices every time, include the following essential elements on your invoice template.

Business Information

Start your interior design invoice template with a section for your contact details such as your full name (and business name if it is registered differently), phone number, street address, email address and website. If you offer any specialized services such as lighting design, sustainable interior design, retail design, etc., add a few lines in this section to mention them.

For more professional invoices, include your interior design business logo, industry-related imagery and any other branding elements.

Client Information

Next, include a section for your client's information starting with their full name (or company name), phone number, billing address, and email address in case you're sending the invoice through email. If you are doing interior design work for large corporate clients, make sure to also address the invoice to the person in charge of the accounts payable department to avoid payment delays. You may also add a client ID number if you maintain a database.

Invoice Number and Date

Make sure to assign a unique invoice number to all of your invoices. This will help you keep better organized accounting records, not to mention large clients usually don't accept invoices without an invoice number. Additionally, include the date when the invoice was sent out, which you can use as a reference to set a payment due date and apply any late fees accordingly.

Project Details

Include a section to briefly describe the interior design project you're charging for such as kitchen renovation, retail store interior design, office reinstatement, etc. You may also mention any other relevant details such as the address, square foot area, and dates in which the project took place. Especially if you are billing your client on different projects this addition will help you keep better track of the services provided and avoid confusion.

Services Provided

Your interior design invoice template must have enough space for a detailed list of the services provided along with a short description of each. If you are charging on an hourly basis, be clear about how many hours were spent on each task, the total hours spent on the project, rate per hour and finally the total labor cost. You may add a timesheet to the invoice so your clients can easily understand how the time they're paying you for was invested.

You want to also specify all the materials, supplies, furniture, and any other items chargeable to your client, including quantities, unit price and total cost for each.


On the totals section of your interior design invoice template, you want to have separate lines to specify the cost of services and materials before taxes (subtotal), then add the applicable taxes, and provide the total amount to pay. This is also the ideal section to include any applicable discounts for regular clients, referrals, etc., by subtracting the discounted amount from the subtotal before you add the taxes.

Payment Details

If you want to increase your chances of getting paid quickly, pay close attention to this section of your interior design invoice template. You want to provide your clients with all the accepted payment methods such as debit/credit cards, checks, cash, ACH transfers or online payments. Add the corresponding account numbers, account holder's name, payment links, and mailing address for the checks.

Add a few more lines to this section to disclose your payment terms including the invoice due date, partial payments, payment arrangements available and late fees that may apply to overdue accounts. Make sure the payment instructions are crystal clear and it's easy for your clients to make payments.


Save a little bit of space at the end of your interior design invoice template to add a personal note, or a message to thank your clients for their business. You may also use this space to encourage referrals, good reviews, or offer a promotion for a second project. All this can help you strengthen client relationships and can easily lead to more business.
