Small business insurance: a starter guide for owners
The usual starter set for a small business: a BOP, then workers' comp, auto, professional and cyber coverage, with ISO BOP limits and a staged buying plan.
Most small businesses begin with a business owner's policy (BOP), which bundles property, business income and general liability for a small or midsize operation, and then add workers' compensation when they hire, commercial auto when a vehicle is used for work, and professional liability or cyber when they handle advice or data. That sequence fits the large majority of Main Street companies: shops, offices, salons, light contractors, restaurants. What follows is the starter set, what a standard BOP does and does not do, and a staged plan for adding coverage as the business grows.
Who this covers
The SBA Office of Advocacy's 2026 edition of its small business FAQ counts about 36.2 million small businesses in the United States, and most of them have no paid employees. That range is wide: a freelancer with a laptop and a 40-person machine shop share a label but not an insurance program. Use this guide as a map, then follow the links for your type of business: insurance for sole proprietors and the self-employed, insurance for freelancers and independent contractors, insurance for a side business or part-time venture, startup insurance: what founders need at each stage or home-based business insurance: why a homeowners policy falls short.
The starter set
| Stage | Coverage to put in place | Why |
|---|---|---|
| Open the doors (lease, inventory, customers) | A business owner's policy: property, business income, general liability | The landlord will ask for it, and it covers the premises and the most common third-party claims |
| Hire the first employee | Workers' compensation, usually required by state law | Medical and wage benefits for work injuries; the thresholds and exemptions vary by state |
| Anyone drives for the business | Commercial auto, or hired and non-owned auto at minimum | A BOP does not cover vehicles you own; see Hired and non-owned auto (HNOA) coverage: what it covers and who needs it |
| You give advice, design or manage something for clients | Professional liability (E&O) | General liability does not respond to financial-loss claims |
| You keep customer data or take cards and payments online | Cyber; crime and funds transfer fraud | The base BOP has only small, limited electronic data coverage |
| Revenue and contracts grow | Umbrella, higher limits, management liability, EPLI | Customers and lenders ask for higher limits as you grow |
What business insurance do I need? A checklist by risk goes deeper on the "why" for each row, and is business insurance required by law? sorts what is legally required from what is merely smart.
What a BOP includes, and where it stops
The ISO Businessowners Policy is built on the Businessowners Coverage Form BP 00 03. ISO's own February 2025 overview describes it as a self-contained package for small and midsize "Main Street" businesses, and states that for most eligible classes the design limits are 35,000 square feet of floor area and $6,000,000 of annual gross sales at each location (Verisk ISO Businessowners overview). Class rules are stricter in places: contractors, for example, must have annual payroll of $300,000 or less, may not work above three stories, and may not subcontract more than 10% of sales, while full-service restaurants are capped at 7,500 square feet and 150 seats. Individual carriers publish their own BOP eligibility, which can be narrower or wider.
Within those limits, the ISO form includes, among many other features:
- Property for the building (if you own it) and your business personal property on a replacement cost basis, subject to an 80% insurance-to-value requirement; the base property deductible is $500.
- Business income and extra expense for up to 12 consecutive months of actual loss sustained, plus up to 60 additional days of extended business income.
- Small built-in extensions such as $10,000 for electronic data restoration, $10,000 for valuable papers, and $5,000 for business income from a dependent property.
- Liability for bodily injury, property damage and personal and advertising injury, with defense costs outside the limit and a medical expenses coverage of $5,000 per person.
The liability limit deserves a closer look. In the ISO program the basic limit is $300,000 per occurrence, which can be increased to $500,000, $1,000,000 or $2,000,000, with an aggregate of twice the occurrence limit. Many leases and customer contracts ask for $1 million per occurrence, so the first thing to check on a BOP quote is whether the limit meets your contracts, not just whether it is cheap. A carrier's own BOP may start higher or lower.
What a BOP does not include is the other half of the starter set: workers' compensation, commercial auto, professional liability, most cyber and flood or earthquake.

A hypothetical example
Say a coffee shop leases 1,400 square feet, has five employees, $450,000 in annual sales, and takes cards on a point-of-sale system. The numbers fit comfortably inside the ISO eligibility limits, so a BOP is the natural base: property for the espresso machine, furniture and inventory, business income if a kitchen fire closes the shop, and general liability for a customer's burn or slip. The owner then adds:
- Workers' compensation, because the shop has employees, with the premium based on payroll and the state's class codes.
- Hired and non-owned auto, because staff sometimes pick up supplies in their own cars.
- Cyber coverage, because card data and customer email lists are an exposure the BOP's $10,000 electronic data limit does not address.
- Higher liability limits or an umbrella, if the landlord's lease asks for more than the BOP provides.
The same exercise for a coffee shop or a retail store takes an hour with a broker, and the output is a short list, not a thick folder. That is what a good starting program looks like. This is a hypothetical, not a quote.
A staged plan
- Before you sign a lease or open: ask the landlord for the insurance clause, list what you own, and decide your entity. An LLC does not replace insurance (Does an LLC need business insurance?).
- Before opening day: have the BOP bound and certificates ready for the landlord and any lender. A certificate of insurance is proof of coverage; it does not change the policy.
- At the first hire: add workers' comp. Check workers' comp and benefits requirements by state for your state's rules and workers' comp for small businesses for how the premium is built.
- At the first vehicle or delivery: talk to your broker about commercial auto before the first trip. commercial vs personal auto: when you need a business auto policy explains why a personal policy may not respond.
- At the first big customer: read their insurance clause and run it through the contract insurance requirements checker before you sign.
- Every renewal: update payroll, sales, vehicles and locations using the annual business insurance review: what to update.
How to buy it
Gather your application information once and reuse it: legal name and entity type, years in business, description of operations, annual sales and payroll by job classification, square footage and construction of the building, vehicles and drivers, prior carriers and loss history for five years, and any contract requirements. Then compare quotes line by line, not by price alone, using the business insurance quote comparison worksheet and how to compare business insurance quotes line by line.
You can buy through an independent agent or broker who shops several carriers, from a carrier's captive agents, or online. Each has trade-offs, set out in independent agent, broker, captive agent or direct? and buying business insurance online: what works and what to watch. Whichever route you choose, ask who is licensed in your state, which carrier issues the policy, and how the carrier handles claims.
Mistakes that cost small businesses
- Guessing at payroll and sales. Workers' comp and general liability premiums are usually estimated at the start and trued up in a premium audit. A low guess becomes a bill later.
- Reading only the declarations. The declarations show limits and premium; the exclusions and endorsements show what happens in a claim. how to read a commercial policy: declarations, forms and endorsements helps.
- Treating a BOP as everything. It leaves out the employee, vehicle and professional exposures above.
- Not telling the carrier when things change. A new location, a delivery service or a product line can alter coverage or eligibility.
- Buying the cheapest limit. A $300,000 liability limit can be exhausted by one serious injury claim.

Key takeaways
- Start with a BOP for the premises, then add workers' comp, auto, and professional or cyber coverage as the business takes on employees, vehicles, advice and data.
- ISO's BOP is designed for small and midsize businesses within size and class limits, with a $300,000 base liability limit that you should raise to match your contracts.
- The BOP leaves out workers' comp, commercial auto and professional liability, so those need their own policies.
- Give your broker accurate payroll, sales and operations; mistakes surface at the premium audit or at claim time.
- Review the program at every renewal and whenever you hire, add a vehicle, sign a major contract or open a location.
