Small business insurance can feel like alphabet soup — GL, BOP, E&O, workers' comp. Here's what each of the common policy types actually covers, in plain language, so you can figure out what your business actually needs.
General Liability (GL)
This is usually the foundation. General liability covers claims that a third party — a customer, a vendor, a visitor — was injured or had property damaged because of your business. Think: a customer slips in your store, or your work accidentally damages a client's property.
It typically covers:
- Bodily injury to non-employees
- Property damage you cause to someone else's property
- Legal defense costs if you're sued over either of the above
It generally does not cover your own employees' injuries (that's workers' comp) or mistakes in the professional advice or service you provided (that's E&O — more on that below).
Almost every small business, regardless of industry, benefits from having some level of general liability coverage — many landlords and client contracts actually require proof of it before you can even rent a space or sign a deal.
Business Owner's Policy (BOP)
A BOP is essentially a bundle — it combines general liability with commercial property coverage (protecting your building, equipment, inventory, and furniture) into a single, usually more affordable package. It's built for small-to-midsize businesses that want the core protections without buying and managing several separate policies.
A BOP is often a good starting point for brick-and-mortar or product-based businesses, since it covers both "someone got hurt" scenarios and "our stuff got damaged or stolen" scenarios in one policy. It typically doesn't include professional liability or workers' comp — those are usually added separately if needed.
Errors & Omissions (E&O) / Professional Liability
This one is aimed at businesses that provide advice, services, or expertise — consultants, agencies, accountants, real estate agents, and similar. E&O covers claims that your professional advice or service caused a client financial harm, even if you didn't make an obvious "mistake" — sometimes it's just a client claiming the work wasn't what was promised.
If your business sells expertise or services rather than physical products, E&O is usually more relevant to you than general liability alone, since GL doesn't typically cover claims about the quality or outcome of professional work.
Workers' Compensation
If you have employees, this is likely required by your state, not optional. Workers' comp covers medical costs and a portion of lost wages if an employee is injured or becomes ill because of their job. In exchange for this coverage, employees generally give up the right to sue their employer directly over a workplace injury — it's designed to be a faster, more predictable system for both sides.
Requirements vary significantly by state — some require it starting with your very first employee, others have thresholds. Worth confirming your specific state's rule directly, since it changes the calculation of whether this is "nice to have" or legally mandatory for your business.
So which ones do you actually need?
A rough way to think about it:
- Have any employees? Workers' comp is probably required, not optional — check your state's rule.
- Do customers or vendors ever physically visit your space, or could your work damage someone else's property? General liability is worth having.
- Do you own or lease a physical space, equipment, or inventory? A BOP may cover you more efficiently than piecing together separate policies.
- Is your business primarily advice, consulting, or a professional service? E&O is worth a serious look, since GL alone likely won't cover a claim about your work itself.
Most small businesses end up needing some combination of these rather than just one. The right mix really comes down to what your business actually does day to day — a boutique with foot traffic has a different risk profile than a solo consultant working from a laptop.
The takeaway
None of these policy types are one-size-fits-all, and the acronyms alone don't tell you what you need — the actual activities of your business do. A conversation with a licensed agent who asks about your specific operations is the fastest way to land on the right combination without over-insuring or leaving a real gap.
