Workers' compensation is the one coverage where South Carolina law, not prudence, sets the floor. In South Carolina, workers' compensation is required once a business has 4 or more employees. The national median cost is $54 a month, but the real driver is payroll and job class - office payroll costs cents per hundred dollars, roofing payroll costs dollars.
Unlike general liability, workers' comp is not optional once you cross your state's employee threshold. In South Carolina, workers' compensation is required once a business has 4 or more employees. Premiums are quoted per 100 dollars of payroll by job classification, which is why the $54 national monthly median stretches widely across trades.

Common questions
Is the cheapest business insurance good enough?
Only if the carrier actually pays claims. Before comparing price, check two public numbers: the insurer's AM Best financial strength rating (A- or better) and its complaint index with state regulators (1.0 is average - lower is better). The difference between a good payer and a bad one is usually a few dollars a month; the difference at claim time is everything.
Is business insurance required by law in South Carolina?
Two lines can be legally required: workers' compensation once you reach the state employee threshold, and commercial auto liability for business vehicles. General liability is not state-mandated, but leases and client contracts routinely require it.
What is a certificate of insurance?
A one-page proof-of-coverage document carriers issue on request, listing your policy types, limits and dates. Landlords, GCs and clients in Irmo ask for it before signing - carriers email it same-day, usually free.
What makes premiums go up the most?
Trade risk class, payroll size, revenue, claim history and coverage limits - roughly in that order. A single recent claim can move pricing more than every discount combined, which is why deductible choices matter.
Does an LLC need insurance too?
Yes - the LLC protects your personal assets from business liabilities, but the business's own assets stay exposed. Insurance pays claims; the LLC just keeps them away from your house. Most owners carry both.
