Standard of care

Standard of care refers to a professional's duty to act reasonably and provide quality services. If you fall short of the standard of care, a client usually has the right to sue.

What is standard of care?

In many industries, the standard of care refers to the level of skill, attention, and professionalism a reasonable business in your industry is expected to provide when delivering services. In simple terms, it’s what clients, courts, and insurance companies expect from a competent professional in your role.

If your work falls below this standard and causes a client financial loss, damage, or data exposure, you could face a lawsuit—often under professional liability insurance (also called errors and omissions or E&O), or cyber insurance claims.

Why is standard of care important for small businesses?

Meeting your standard of care isn’t just about doing good work, it directly affects your legal risk and insurance costs.

When you fail to meet industry expectations, clients may claim you were negligent. Even if the mistake was unintentional, it can still lead to:

Costly lawsuits
Reputation damage
Higher insurance premiums
Coverage restrictions or non-renewals

Insurance carriers assess how likely your business is to make mistakes that result in claims. Businesses with weak controls, poor documentation, or repeated errors are seen as higher risk and they pay more for coverage.

How do courts decide what your standard of care is?

Your standard of care depends on your industry and profession, experience level, what other similar professionals would reasonably do in the same situation, and any contracts or promises you made to the client.

For example:

An IT consultant is expected to follow cybersecurity best practices.
A bookkeeper is expected to follow accepted accounting standards.
A cleaning business is expected to use safe, appropriate products and procedures.

If your actions fall short of what’s considered reasonable in your field, it may be considered a breach of standard of care.

Industry standards and benchmarks

Additionally, your standard of care may also be measured against:

Industry best practices
Professional guidelines or certifications
Regulatory requirements
Technical frameworks (e.g., PCI DSS for payment data or HIPAA for healthcare-related services)

These benchmarks help define what “reasonable” looks like in your profession.

Examples of good and poor professional practices

Here are a few realistic business scenarios that show the difference between meeting your professional responsibilities and exposing your business to costly claims.

A marketing consultant documents client goals, confirms deliverables in writing, and reviews campaigns for accuracy before launch.	A web developer launches a client site without testing security settings, leading to a data breach.
A contractor follows local building codes and manufacturer installation instructions.	A cleaning service recommends a harmful chemical that causes permanent damage to a client's floor.

How does standard of care affect your insurance costs?

Insurance companies price your policy based on risk. Your business looks riskier to insure if you:

Have poor documentation
Lack internal controls
Don’t follow industry standards
Have a history of claims

That often leads to higher premiums, lower limits, or fewer carrier options.

On the other hand, businesses that clearly demonstrate strong risk management and quality controls often qualify for better pricing and broader coverage.

Risk controls that can lower your insurance costs

Here are practical steps that help you meet your standard of care and reduce your insurance risk:

Use clear written contracts: Define your scope of work, set realistic expectations, and include limitations of liability.
Document everything: Keep records of client communications, save approvals and changes in writing, and maintain project timelines and deliverables.
Implement quality checks: Use checklists before delivering work, review for errors or compliance issues, and catch mistakes before clients do.
Train your team: Provide ongoing education in your field, cybersecurity awareness training, and certifications when applicable.
Track and fix mistakes: Log errors internally, identify patterns, and improve processes to prevent repeat issues.

These controls signal to insurers your business is serious about risk, which can directly impact your premiums and eligibility.

How does insurance protect you from standard of care claims?

Even the best businesses can make a mistake. That’s why having the right insurance can protect you from a variety of risks, such as:

Professional liability insurance covers claims of negligence, errors, or failure to meet professional standards.
Cyber insurance helps cover costs related to data breaches, social engineering attacks, and digital mistakes.
General liability insurance may apply if your work causes property damage or bodily injury.

Ultimately, your standard of care is the baseline your clients and insurers expect you to meet. When you protect that standard with good processes, documentation, training, and the right insurance, you don’t just reduce lawsuits—you build a stronger, more insurable business.
