6 invoicing rules every interior designer should follow
Separate design fees from purchasing
Always use separate line items for design fees and procurement. Clients who see one combined total don't understand what they're paying for and often push back on markup. Transparent itemisation — 'Sofa: trade price $1,800 + 30% markup = $2,340' — builds trust and reduces disputes.
Require a design deposit before starting
Collect a deposit equal to 25–50% of your estimated design fee before the first site visit. This filters out window shoppers and ensures you're paid for discovery work. State the deposit on the invoice: 'Design deposit ($X) required prior to project commencement.'
Invoice purchasing funds in advance
Never use your own money to purchase items for a client. Send a purchasing invoice for the full procurement amount before placing any orders. Release the items on delivery after payment clears. This protects you from clients who cancel orders after goods have shipped.
Charge for all site visits and meetings
Site visits, contractor meetings, showroom visits, and client calls all take billable time. Either include them in your flat fee (and price accordingly) or bill hourly. Never treat site visits as free — each one is 3–6 hours of your day including travel.
Build your markup into the procurement line, not as a separate fee
Clients react better to 'Dining table: $4,200' than 'Dining table: $3,230 + 30% markup: $969'. The total is identical, but transparent markup percentage lines invite negotiation. Document your markup policy in your contract, not your invoice.
Send a closeout invoice for project hours on completion
For hourly projects, send a final hours reconciliation invoice when the project closes. List all hours by category (design, PM, admin), match against any retainer paid, and invoice the balance or refund the overpayment. Don't let unbilled hours accumulate for months.

- Purchasing amounts itemised (with attached quote/schedule)
- Site visit hours and dates
- Any deposits previously received (deducted)
- Total amount due — prominent and clear
- Payment method and account details
- Purchasing policy: 'Orders placed on receipt of purchasing deposit'
Frequently asked questions
Should interior designers charge sales tax on design fees?
It depends on your state and how your services are structured. Many US states exempt professional design fees from sales tax but tax product sales. Some states tax design fees that are bundled with product sales. Check your state's specific rules — misclassifying taxable and non-taxable services is a common audit trigger.
How do I invoice a client who cancels mid-project?
Your contract should define a cancellation clause. Invoice for all hours worked to date, any non-refundable deposits paid to vendors on the client's behalf, and a cancellation fee if specified in your agreement. If you purchased items that can't be returned, those are billed to the client at full value.
How do I invoice for an e-design project?
E-design is typically flat-fee: bill 50% upfront and 50% on delivery of the design package. The package should be clearly defined — number of rooms, what's included (mood board, floor plan, shopping list), and what's excluded (procurement, contractor coordination). Deliver via PDF or a client portal link.
What markup should interior designers charge on furniture?
Trade markup varies from 20% to 35% depending on your market, project type, and procurement volume. Residential designers typically mark up 25–30%. Always state your markup policy in your letter of agreement, not on individual invoices — invoice line items show the final price to the client.
What payment terms should interior designers use?
Design fees: Net 14 or due on presentation. Purchasing: 100% upfront before ordering. Project management: invoiced monthly in arrears, Net 7. Installation and styling: invoiced on completion, Net 7. Avoid Net 30 on any line — construction timelines are long enough already.
