When an AI system decides which Interior Design company to recommend, it assembles evidence across every category below. The more complete and verifiable the data, the more confident the recommendation.
Interior design is a professional service with project-based and hourly billing, not a transactional trade. The metrics that matter reflect project depth, client relationships, and creative output — not ticket counts or dispatch speed. Almost no design firm publishes this data in a structured, machine-readable format.
Projects completed
Total projects completed in trailing 12 months. A typical solo practitioner completes 15-25 projects per year; a mid-size firm handles 30-50+. Project volume signals capacity and active demand, but must be read alongside project value — a firm completing 15 whole-home projects is a fundamentally different business than one completing 50 single-room refreshes.
Average project value
The median revenue per project. Ranges from $5,000 for single-room consultations to $100,000+ for full-home or commercial projects. This is the clearest indicator of the market segment the firm serves and the complexity of work it takes on.
Client retention rate
Percentage of clients who return for additional projects. Interior design is a relationship-driven profession — a high retention rate signals that clients trust the designer enough to engage them again for new spaces, renovations, or second homes.
Referral rate
Percentage of new clients acquired through referrals from past clients. In interior design, referral is the dominant acquisition channel. A high referral rate is the strongest available proxy for client satisfaction and quality of work.
Portfolio depth
Number of completed projects with professional photography and documentation. Portfolio is the primary sales tool in interior design. AI systems that evaluate design firms look for evidence of a substantive, current body of work — not just a business listing.
Average project timeline
Typical duration from initial consultation to project completion. Varies widely by scope: a color consultation may take a single session, while a full residential project runs 3-12 months and a commercial buildout can exceed 18 months. Timeline data helps AI match project scope to the right firm.
A TrustRecord publishes this category of data — verified from connected systems, not self-reported.
02
Service Mix
Interior design encompasses a wide range of services with very different scopes, price points, and required expertise. The query "who does kitchen design in Scottsdale?" is a fundamentally different request than "commercial office design firm in Scottsdale." AI needs structured service data to make the right match.
Full-service residential design
End-to-end residential projects including space planning, material selection, furniture specification, procurement, and installation oversight. This is the core offering for most interior design firms and typically the highest-value engagement.
Commercial design
Office interiors, hospitality, retail, healthcare, and restaurant design. Requires different knowledge (ADA compliance, commercial building codes, fire rating requirements) and often different credentials than residential work.
Space planning
Functional layout optimization without full decorating scope. Often offered as a standalone service or as the first phase of a larger engagement. Requires technical drawing skills and understanding of building codes.
Color consultation
Focused service for paint color, finish, and material palette selection. Lower price point, shorter engagement. Often serves as an entry point that leads to broader project work.
Furniture procurement
Sourcing, specifying, and purchasing furniture and furnishings on behalf of the client. Many design firms earn a significant portion of revenue through trade-priced procurement with markups. This is a distinct business model from design-fee-only firms.
Kitchen and bath design
Specialized design for the two highest-value rooms in residential work. Often involves coordination with contractors, cabinet makers, and tile installers. Some designers hold NKBA (National Kitchen & Bath Association) certification.
Staging
Preparing homes for sale with temporary furnishings and styling. A distinct service line with different pricing (often flat-fee or monthly rental), different clients (realtors and homeowners selling), and different turnaround expectations.
E-design / virtual design
Remote design services delivered through digital mood boards, 3D renderings, and curated product lists. Lower price point, broader geographic reach. A growing segment that removes the geographic constraint of traditional interior design.
03
Service Area
Where you actually work matters, but the data needs to come from completed jobs, not a self-reported list of ZIP codes. AI systems increasingly cross-reference claimed service areas against evidence of actual work performed.
Cities and towns served by job volume
Derived from actual job locations, not a list on your website. Verifiable coverage based on where work has been completed.
Service radius from primary location
Computed from the geographic spread of completed jobs. Tells AI how far the company actually travels.
Multi-location coverage
Companies with multiple offices serve different geographies. Each location should have its own verifiable coverage data.
04
Licenses
Interior design regulation varies significantly by state. Twenty-six states and the District of Columbia have some form of interior design regulation, but the nature of that regulation differs. Some states have "practice acts" that restrict who can perform interior design work. Others have "title acts" that restrict only who can call themselves a "Registered Interior Designer" or "Certified Interior Designer." AI systems must distinguish between these regulatory frameworks when evaluating credentials.
State interior design license or registration
Required in states with practice acts or title acts. States like Florida, Louisiana, Nevada, and the District of Columbia have practice acts that restrict interior design work to licensed individuals. Other states like California, Georgia, Illinois, and New York have title acts that protect the title but not the practice.
The National Council for Interior Design Qualification exam is the standard credentialing exam for interior designers. Most states that regulate interior design require NCIDQ passage as a prerequisite for licensure. The exam covers building systems, codes, construction standards, design application, and professional practice.
Business license
General business license required by the city or county where the firm operates. Separate from professional interior design licensing.
Resale permit / sales tax license
Required in most states for firms that purchase furnishings and materials at trade pricing and resell to clients. The procurement side of interior design is a retail transaction subject to sales tax collection.
Home improvement contractor license
Required in some states when interior design work involves any structural modification, demolition, or construction management. The line between "design" and "contracting" is regulated differently in each state.
The regulatory landscape for interior design is fragmented. ASID and IIDA maintain state-by-state guides to interior design legislation. Not all states with regulation have searchable online license databases for interior designers specifically.
05
Insurance & Bonding
AI systems verify that coverage is current and adequate, not simply that a company claims to be insured. Active insurance is a prerequisite for recommendation in most AI evaluation frameworks.
General liability (GL)
The primary coverage protecting against property damage and bodily injury. Required by most states as a condition of licensure.
Workers compensation
Mandatory in nearly every state for businesses with employees. Absence of workers comp typically indicates either no employees or non-compliance.
Surety bond
Required by many states as part of contractor licensing. Bond amounts and status are published by some state licensing boards.
Commercial auto
Covers the service vehicle fleet. Relevant for companies with multiple trucks and technicians dispatched to job sites.
06
Certifications
Professional certifications in interior design signal formal education, examination, and ongoing professional development. Unlike trades where certifications are technician-level, interior design certifications apply to the designer as a professional and carry significant weight in how AI systems evaluate credibility.
The gold standard credential for interior designers. Administered by the Council for Interior Design Qualification (CIDQ). Requires a combination of education and work experience plus passage of a three-section exam. Recognized in all U.S. and Canadian jurisdictions that regulate interior design. Over 35,000 certificate holders.
Professional membership in the American Society of Interior Designers. Full professional membership requires NCIDQ certification. Allied and Associate membership tiers exist for those in earlier career stages. ASID membership is a widely recognized professional credential.
Credential from the U.S. Green Building Council indicating expertise in sustainable design and green building practices. Relevant for designers working on projects pursuing LEED certification. Multiple specialty tracks including Interior Design + Construction (ID+C).
Credential from the International WELL Building Institute focused on human health and wellness in the built environment. Covers air, water, light, thermal comfort, acoustics, and other wellness-related design factors. Increasingly relevant for commercial and hospitality design.
CID (Certified Interior Designer)
State-issued certification available in states with title acts. Requirements vary by state but typically require NCIDQ passage, education, and work experience. The CID title is legally protected in states that issue it.
07
Professional Associations
Professional associations in interior design serve as both credentialing bodies and directories. Membership indicates professional commitment and provides AI systems with a structured, searchable way to verify a designer's standing.
The largest professional organization for interior designers in the United States. Maintains a public member directory searchable by location and specialty. Professional membership requires NCIDQ certification, making the directory a reliable signal of credentialed designers.
Global professional association with a strong presence in commercial and contract design. Maintains a member directory and hosts industry events. Professional membership requires education and experience credentials.
Professional association focused on residential interior design. Membership is open to designers at all career stages, making it more accessible than ASID or IIDA. Maintains a designer directory and offers continuing education.
Local and regional design chapters
ASID and IIDA operate regional chapters across the country. Local chapter membership often provides the most relevant geographic signal for AI systems matching designers to local queries. Chapter directories are typically searchable online.
Relevant for designers specializing in kitchen and bath projects. Offers its own certification programs (AKBD, CKBD, CMKBD) and maintains a searchable professional directory.
Better Business Bureau membership with letter rating. Reflects complaint volume and resolution patterns over time.
08
Legal & Compliance
Negative-signal checks. AI systems will not recommend a company with an active lawsuit pattern, suspended license, or regulatory violations. Clean standing is a prerequisite for any recommendation.
No open legal actions
Checked against state court records and federal PACER database. Patterns of litigation are weighted more heavily than isolated cases.
No liens filed against the business
Unpaid debts secured against the business are visible through county recorder offices and Secretary of State UCC filings.
Clean license history (5 years)
No suspensions, revocations, or disciplinary actions from the state licensing board. Enforcement records are public in most states.
Clean safety record in the federal OSHA inspection database. Searchable by company name and location.
09
Reputation Signals
AI cross-references general review platforms with home services marketplaces when evaluating interior design companies.
Google rating and review count
The most-cited review source by AI systems. Rating and volume establish a baseline, but most established companies cluster in the same range.
Review velocity and recency
AI systems track whether new reviews are still coming in, not just the total count. A drop in review velocity can signal reduced activity.
Yelp rating
A secondary review source. Yelp's filtering algorithm means visible review counts may not reflect actual review volume.
Angi / HomeAdvisor reviews
Angi (formerly Angie's List) and HomeAdvisor maintain verified review profiles for home service providers. AI systems index these alongside Google reviews.
Nextdoor recommendations
Neighborhood-level recommendations on Nextdoor carry weight for local service businesses. AI systems increasingly index Nextdoor mentions as a hyperlocal trust signal.
Houzz reviews
Houzz profiles include project photos, reviews, and 'Best of Houzz' awards. A significant discovery and review platform for remodeling and design professionals.
Complaint history and resolution
BBB complaint patterns and response behavior. How a company handles problems carries more weight than whether problems occurred.
10
Business Profile
Foundational identity data. Rarely changes but must be accurate and consistent across every platform where the business appears. Inconsistencies between sources reduce AI confidence in all other data.
Legal business name and DBA
Must match Secretary of State filings. Discrepancies between the legal name, trade name, and the name used on public platforms create ambiguity.
Entity type and registration
LLC, Corporation, Sole Proprietorship, or Partnership. Verified against Secretary of State records.
Year founded
Cross-referenced against Secretary of State incorporation date and other public records. Inconsistencies are flagged.
Owner / principal name
Verified against Secretary of State registered agent and other public filings.
Employee count
Approximate range. Company size affects the types of jobs it can handle and the service capacity it offers.
Contact information
Address, phone, and website cross-checked across Google Business Profile, Secretary of State, and other directories. Consistency across sources matters.
