Interior Design Invoice Template: Bill Fees, Furniture, and Expenses

Short answer

An interior design invoice template should identify the client and property, project phase, consultation or design fees, procurement services, furniture and materials, contractor costs, travel, deposit, tax, balance, and payment terms. Separate professional fees from purchased products and pass-through expenses.

What to include

• Designer or studio business details.
• Client, property, room, and project reference.
• Invoice number, issue date, service period, and due date.
• Consultation, concepts, drawings, specifications, and project management.
• Procurement or purchasing fee.
• Furniture, fixtures, finishes, samples, freight, and installation.
• Contractor or specialist costs when billed through the designer.
• Deposit, previous payments, credits, tax, currency, and total.

Clear invoice line-item descriptions help clients match charges to the approved design proposal.

Example line items

| Description | Amount | | --- | ---: | | Concept design and space planning | $1,200 | | Furniture procurement service | $450 | | Dining table and freight | $1,850 | | Site visit and installation coordination | $300 | | Deposit paid | -$1,000 |

For larger projects, use an invoice installment payment plan tied to design, procurement, installation, and completion milestones.

Procurement and client approvals

State whether product costs include a markup, procurement fee, freight, or tax. Get written approval before ordering non-refundable products or adding work outside the scope. Keep supplier invoices and client approvals with the project records.

FAQs

Should furniture appear on the designer's invoice?

It may when the designer purchases it for the client. Show products, freight, procurement fees, and tax clearly.

Can interior designers invoice by milestone?

Yes. Milestones work well for concept approval, procurement, installation, and final completion.

How should travel be billed?

Follow the agreement and show approved travel as a separate line or reimbursable expense.
