Frequently Asked Questions
Separate each service type into distinct line items: initial consultations, space planning, color scheme development, furniture selection, custom design work (window treatments, layouts), sourcing and procurement, and project management. This clarity helps clients understand what they're paying for and justifies your fees. Itemizing services also makes it easier to track billable hours and adjust pricing for future projects based on which services take the most time.
Yes. Separate your design labor (hourly or flat-rate consulting fees) from product sourcing and procurement. Clearly itemize furniture, fabrics, finishes, and materials with their costs. Many designers apply a markup (typically 20–50%) to sourced products to cover procurement time, vendor relationships, and project coordination. Transparency prevents client confusion and justifies why their total investment includes both your expertise and product costs.
Interior designers typically use hourly rates or flat-rate consultations. Initial consultations range from $100–$300 per hour depending on your market and experience; flat rates work well for fixed consultations. Specify the consultation type: discovery meetings, space assessments, or follow-up reviews. This approach is clearer than bundling consultations into project fees, and it helps you bill accurately whether the client is an individual or commercial client with multiple phases.
Most interior design projects use a three-payment structure: a 50% deposit to begin work and secure materials, 25% at the midpoint or upon client approval of selections, and the final 25% upon project completion. Some designers use milestone billing tied to project phases. This protects your cash flow and ensures clients are committed. State payment terms clearly on your invoice: due date, late payment policy, and accepted payment methods.
Define your revision policy upfront: include 1–3 rounds of revisions in your initial design fee, then charge separately for additional revisions (typically $75–$150 per round). Invoice revision work as a separate line item labeled "Additional Design Revisions" with the hourly rate or flat fee. This protects against scope creep and helps clients understand that ongoing changes require additional investment beyond the original agreement.
This depends on your business model. Some designers act as retailers, purchasing all furnishings and materials, then invoicing clients for those items plus design fees. Others provide sourcing recommendations and clients purchase directly. If you're invoicing for materials, include them as separate line items with your cost and markup clearly shown. If clients purchase directly, invoice only your design services, consultation hours, and sourcing time.
Invoice at key project milestones rather than at the end. Send invoices for the design deposit immediately after the client signs the agreement, invoices for each project phase (concept, selections, installation coordination) as work completes, and a final invoice upon project closeout. Milestone invoicing accelerates cash flow and aligns payments with your actual work completion, which is especially important for projects spanning weeks or months.
Add a rush fee as a separate line item on your invoice, typically 15–50% above your standard hourly rate or project fee depending on how compressed the timeline is. Label it clearly: "Rush Project Surcharge" or "Expedited Design Fee." Discuss rush pricing before starting work so clients expect the additional charge. This compensates you for prioritizing their project and coordinating vendors under tight deadlines.
