Interior Design Client Onboarding Checklist: Documents, Scope, Approvals and Project Kickoff

Summary

A structured client onboarding process helps interior designers clarify project requirements, collect essential documents, define scope, and establish approval procedures before work begins. Use this practical checklist to organize your next project kickoff and reduce avoidable delays.

A successful interior design project starts before the first concept. Clear client information, agreed responsibilities and documented approvals help prevent misunderstandings, revisions and delays. Use this checklist to make onboarding consistent.

1. Collect Client Requirements

Record the client's contact details, property address, intended use of each space, preferred style, priorities, budget and target completion date. Ask what is not working and what success looks like. Identify who will review designs, approve materials, authorize changes and release payments. Agree how feedback will be consolidated when several people are involved.

2. Gather Essential Documents

Request the information needed to understand the site:

Existing floor plans, architectural drawings and services layouts.
Site measurements and photographs.
Relevant electrical, plumbing or HVAC information.
Building rules, access timings and renovation restrictions.
Budget, reference images, material preferences and items to retain.

Verify drawings against site conditions. Record gaps and arrange measurements when needed; do not assume old plans are accurate.

3. Define Scope and Deliverables

Document the spaces covered, design stages, drawings and schedules, review rounds, site visits and coordination responsibilities. Clarify whether procurement or execution supervision is included. List exclusions and explain how additional work or revisions will be priced and approved. A clear scope prevents different expectations.

4. Confirm Fees and Communication

Share the fee proposal and payment milestones before work begins. State when payments are due and how approved changes affect costs or timelines. Use an appropriate written agreement and seek professional advice when required.

Agree on communication channels, response times, meeting frequency and decision-makers. Record important decisions rather than leaving them buried in messages.

5. Establish the Approval Process

Explain how the client will review layouts, 3D views, drawings, finishes and material selections. Record each submission's version, feedback, approver and decision date. Proceed with procurement or execution only after the relevant approval.

Document changes requested after approval and confirm their effect on fees, procurement and schedule before proceeding. This helps prevent outdated drawings or unapproved materials reaching the site.

6. Conduct a Project Kickoff

Align everyone on objectives, budget, scope, milestones, responsibilities and next steps. Give every action an owner and due date. Confirm what the client must provide, what the studio will deliver first and when the next review will happen.

Before closing, check that the brief and site information are complete, payment terms are understood, approval responsibilities are assigned and the next meeting is scheduled.

7. Keep Project Information Organized

Store the brief, drawings, decisions, material selections, tasks and meeting notes in a shared workspace. Give collaborators role-appropriate access and make approved information easy to identify.
