Field-by-field breakdown
- From: Firm name, professional membership (ASID, IIDA), studio address, and billing email.
- To: Homeowner or client and the project address.
- Project reference: Name the specific rooms and scope.
- Design fees: Consultation, space planning, renderings, and project management. These are your professional services.
- Product procurement: Each furnishing item listed with the vendor name and client price (your cost plus markup).
- Markup disclosure: Industry standard is 20-35% over trade/wholesale cost. Some designers disclose the markup method; others show only the client price.
- Freight: White-glove delivery is a significant cost that should be its own line item.
- Tax: Products are taxable in Louisiana. Design services may or may not be, depending on the state.
Common line items for interior designers
| Line Item | Typical Rate Range |
|---|---|
| Initial consultation (1-2 hours) | $150 -- $500 |
| Concept and design development (flat fee) | $1,500 -- $10,000 |
| 3D renderings (per room) | $500 -- $2,000 |

Variations
- Flat fee vs. hourly: Some designers charge a flat project fee; others bill hourly for design time plus product markup.
- Cost-plus model: Disclose trade cost and add a transparent percentage markup (e.g., "trade cost $3,600 + 30% = $4,680").
- Retail model: Quote client price only without disclosing trade cost. Simpler for the client.
- Commercial projects: Bill by square foot for space planning and use purchase orders for FF&E procurement.
Tips for interior design invoicing
- Separate design fees from product costs so clients understand what they are paying for your expertise vs. furnishings.
- Require deposits before placing orders -- you should never front the cost of custom furniture.
- Include lead times in your notes so clients know when to expect delivery.
- Invoice at each project phase (concept, procurement, installation) rather than one lump sum at the end.
FAQ
Q: Should I charge sales tax on design fees? A: It depends on the state. Many states exempt professional design services but tax product sales. Louisiana taxes products but not most professional services. Consult your accountant.
Q: How do I handle a client who wants to source their own furniture? A: Offer a design-only fee structure at a higher hourly rate to compensate for lost product markup. Specify in your design agreement that you are not responsible for sourcing, delivery, or quality of client-sourced items.
Q: What if a custom order arrives damaged? A: File a claim with the vendor or freight company. Note on your invoice that product warranties are through the manufacturer, not your firm.
