Free Invoice Template for Interior Designers

Interior design invoices often combine professional fees, procurement pass-throughs, and project management. Clear separation of each keeps clients informed and protects you professionally. Include:

• Project name and room(s) in scope
• Design phase — concept, space planning, detailed design, procurement, installation, styling
• Service description — mood board, FF&E schedule, technical drawings, contractor coordination
• Your design fee — clearly separated from any procurement or product costs
• Procurement items — furniture, fabrics, lighting, accessories passed through to client
• Your trade discount or markup — disclosed transparently
• Payment milestone — what triggers this invoice

Flat design fee: A fixed fee per phase or room — most transparent for clients. Covers all design work for the defined scope regardless of time. Works well for well-scoped residential projects.

Hourly rate: Good for consultations, revisions, project management overruns, or exploratory work with undefined scope. Senior interior designers typically charge £75–£200/hour in the UK.

Procurement commission: Many interior designers receive trade discounts of 20–40% from suppliers and pass the goods to clients at retail or with a transparent markup. Disclose your commission policy in your contract and reference it on the invoice.

Day rate: Used for site visits, contractor meetings, and installation supervision. Specify what "on-site day" includes.

When you procure goods on behalf of a client, invoice them separately from your professional fee:

• FF&E (Furniture, Fixtures and Equipment): List each item — product name, supplier, quantity, unit price, and your markup. "Sofa — Maker&Son — 1 × £3,200 + 15% procurement fee = £3,680"
• Fabrics and soft furnishings: Invoice by the metre or per item, noting the supplier and colourway
• Delivery and installation charges: Pass through at cost or with a coordination fee
• Trade account deposits: If you pay a supplier deposit on the client's behalf, invoice for this immediately — don't fund client purchases from your own cash

Interior design services are standard-rated professional services for tax purposes:

• UK interior designers: Register for VAT at £90,000 turnover. Both professional fees and any goods procured and sold to clients are VATable at the standard rate (20%).
• EU interior designers: Standard VAT rates apply to both services and goods. If you buy goods from EU suppliers and resell them, you need to understand the relevant VAT rules for goods procurement.
• Procurement income: Your trade discount/commission is taxable income — it's not just a pass-through. Keep clear records of trade purchase prices and client sale prices.
