Businesses are establishments with 20 to 499 employees (U.S. Census Bureau, County Business Patterns 2023), the small and mid-sized range MSPs sell to; the SBA Office of Advocacy counts firms under 500 employees as small businesses. Change and concentration: U.S. Bureau of Labor Statistics, Quarterly Census of Employment and Wages, private ownership, 2025 Q2.

Manufacturers run larger in Columbia than across our 100 metros, which puts more of them in Tier 1. Private schools and education providers, law firms, architecture and engineering firms and real estate brokerages and property management offices run smaller, so those groups need a seat-count question before a meeting is booked.

• Construction contractors are the largest group in Columbia with 184 businesses of 20 to 499 employees, fewer than Charleston has (216): close to the national mix, up 40 establishments in a year, and typical in size (15% with 50 or more employees).

• Medical, dental and outpatient practices are the second-largest group in Columbia with 181 businesses of 20 to 499 employees, fewer than Charleston has (216): close to the national mix, up 35 establishments in a year, and typical in size (11% with 50 or more employees).

• Manufacturers are the third-largest group in Columbia with 179 businesses of 20 to 499 employees, more than Charleston has (138): close to the national mix, up 19 establishments in a year, and larger than across our 100 metros (43% of those with 10 or more employees have 50 or more, against 32%), so plan on two or three contacts per account.

• Wholesale distributors are the fourth-largest group in Columbia with 156 businesses of 20 to 499 employees, more than Charleston has (128): less concentrated than nationally (0.81x), down 5 establishments in a year, and typical in size (18% with 50 or more employees).

• Nonprofits and member organizations are the fifth-largest group in Columbia with 99 businesses of 20 to 499 employees, more than Charleston has (62): close to the national mix, down 2 establishments in a year, and typical in size (15% with 50 or more employees).

• Private schools and education providers are the sixth-largest group in Columbia with 46 businesses of 20 to 499 employees, fewer than Charleston has (62): close to the national mix, flat over the year, and smaller than across our 100 metros (18% have 50 or more employees, against 25%), so confirm the seat count early on the call.

After those six come law firms (39), architecture and engineering firms (38), accounting, tax and bookkeeping firms (17), insurance agencies and brokerages (17), real estate brokerages and property management offices (13) and wealth management and investment firms (3), smaller groups to work by fit rather than volume.

Where a rule or a client review puts a date on security work in Columbia: medical, dental and outpatient practices (181, HIPAA), manufacturers (179, CMMC where they supply defense work), law firms (39, client security questionnaires), accounting, tax and bookkeeping firms (17, the FTC Safeguards Rule), insurance agencies and brokerages (17, carrier and state insurance data security requirements) and wealth management and investment firms (3, SEC and FINRA exams); together, 436 businesses where the first message can lead with the requirement instead of the service.

407 IT services firms are based in the Columbia metro. That is 28 fewer than a year ago. When an IT firm closes or sells, its customers go looking for a new one. The IT services industry is at about the national concentration. 2.4 target businesses per IT firm puts Columbia 62 of 100 markets, and 2 of 3 in South Carolina. That sits mid-pack: real room to grow, but the best accounts are contested. If you can serve Greenville, it has more target businesses per IT firm than Columbia.

Tier 1 covers construction contractors, medical, dental and outpatient practices and manufacturers with 50 to 499 employees.

Richland County and Lexington County hold 93% of the target businesses across the 6-county metro. The other 4 counties split the remaining 7%, which is where Tier 1 accounts justify the drive and smaller sites do not.

A new office or location needs network, devices and security set up before people move in, and the provider who does that work is in the best position to support it after.

• Construction contractors: 40 more establishments than a year ago

  In this category the usual openings are office growth, a new branch, job site connectivity problems, a wire fraud attempt, a cyber insurance renewal.

• Medical, dental and outpatient practices: 35 more establishments than a year ago

  In this category the usual openings are a new location, a HIPAA risk assessment, an EHR or practice management change, a security incident.

• Manufacturers: 19 more establishments than a year ago

  In this category the usual openings are an ERP upgrade, a ransomware incident in the industry, a defense supplier CMMC requirement, a new line or facility.

• Real estate brokerages and property management offices: 26 fewer establishments than a year ago

  An acquisition puts a business under new owners, who usually review who runs IT and fold it into their own systems.

• 28 fewer managed service providers than a year ago

  Clients of an IT firm that closed, retired or sold have to decide who supports them next.

More questions for every prospect type, and how to follow up after the meeting, are in the MSP prospecting playbook.
