| Requirement | New Hampshire rule |
|---|---|
| Employee threshold | Every employer with any employees, full-time or part-time, must cover them with workers' compensation insurance written by a carrier. |

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.
Does getting a quote affect my current policy or credit?
No. Business insurance quoting does not involve a credit pull in most states and never touches an existing policy. Owners routinely re-quote at renewal to keep their carrier honest.
How fast can coverage start?
Online carriers commonly bind coverage the same day. If a landlord or client is waiting on a certificate of insurance, the COI typically arrives by email within an hour of purchase.
Are online quotes as accurate as an agent's?
They are built from the same underwriting inputs - trade, payroll, revenue, location, claims. The price is bindable, not an estimate. What an agent adds is judgment on coverage shape, which matters most for unusual or high-risk operations.
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 Portsmouth ask for it before signing - carriers email it same-day, usually free.
