Invoice clients for design consultations, project management, and procurement services with a professional template built for interior designers.
An interior designer invoice is a billing document that records design services and related costs for residential or commercial projects. It covers initial consultations, concept development, space planning, material sourcing, procurement, and project management. Interior designers often invoice in phases tied to project milestones, helping clients understand costs at each stage and giving designers predictable cash flow on longer engagements.

| Initial Design Consultation | $150 - $350 | per hour |
| Full Room Design Package | $1,500 - $6,000 | per room |
| Space Planning and Layout | $500 - $2,000 | per space |
| 3D Rendering | $300 - $1,000 | per render |
| Procurement / Purchasing Fee | 10% - 30% markup | on goods |
| Project Management | $100 - $200 | per hour |
| FF&E Specification (per item) | $50 - $150 | per item |
Interior design projects typically span weeks or months, so milestone invoicing is the most practical approach. Common milestones include: initial deposit at project start, concept approval, design development completion, and final installation. For hourly engagements, invoice bi-weekly or monthly with a detailed timesheet attached. Procurement is usually billed at cost plus a markup (10-30%) or a flat purchasing fee. Reimbursable expenses like travel, fabric samples, or permit fees should be invoiced separately with receipts. For large projects, requiring a retainer upfront and drawing against it as work progresses gives both parties financial clarity.
