What to Include on a Interior Designer Proposal
Billing Tips for Interior Designers
Disclose your procurement markup percentage in writing before the first purchase. The industry standard is 20-35%, and clients who discover the markup after receiving a vendor invoice will feel deceived. Transparency upfront turns your markup into a feature (you handle sourcing, logistics, and quality control) rather than a hidden fee.
Separate your design fee from procurement costs on every invoice. Your creative expertise is billed hourly or as a flat project fee, while procurement is a separate line item with the markup shown. This two-track billing model lets clients see the value of your design work independently from product costs.
Collect a procurement deposit before placing any vendor orders. Furniture and materials often require 50% deposits that come out of your cash flow if you front the money. Structure your contract so the client funds a procurement account that you draw from, eliminating the need to carry vendor costs yourself.
Bill for site visits, travel time, and installation supervision as separate line items. These are legitimate work hours that clients often overlook. By listing them transparently, you set expectations and avoid absorbing costs that should be part of the project budget.

Frequently Asked Questions
- Should an interior design proposal include a mood board?
- A preliminary mood board or visual direction board demonstrates your aesthetic sensibility and helps the client visualize your approach. It is one of the most persuasive elements of a design proposal and distinguishes you from competitors who only submit text-heavy documents.
- How do I present procurement budgets in a design proposal?
- Provide a budget range per room or zone (e.g., Living Room: $8,000-$12,000) rather than exact figures. This allows flexibility during the design development phase while setting realistic expectations for the client's total investment.
- How many design concepts should I include in a proposal?
- Offer two to three initial concept directions with distinct visual themes. More than three overwhelms the client and increases your unpaid speculative work. Specify that the chosen concept will be developed further in the design development phase.
- Should I disclose my markup percentage in the proposal?
- Yes. Transparency about your procurement markup builds trust and prevents uncomfortable conversations later. Frame it as a service: you handle vendor sourcing, quality control, logistics, and returns so the client does not have to.
- How do I scope a proposal for a full-home interior design project?
- Break the project into rooms or zones, each with its own scope, timeline, and budget range. Prioritize rooms and offer to phase the project if the total budget exceeds the client's comfort level. This modular approach makes large projects feel manageable.
