What to keep human

  • Complaints and refunds.
  • Anything involving health, legal, or financial advice.
  • Upset customers who need empathy.

Research published by NBER found AI assistance helped support staff resolve issues faster, especially less experienced agents. These figures are third-party research for context, not a prediction of what any single business will see. Salesforce's SMB trends also track growing AI use among small teams.

Can AI fully replace customer service staff? +

No. AI handles routine questions well, but humans should own complaints, judgment calls, and emotional situations.

What is the best AI tool for small business support? +

It depends on your channels. Email teams benefit from AI-assisted helpdesks; high-traffic sites benefit from chat assistants.

Will customers know they are talking to AI? +

Be transparent. Disclose AI use and make it easy to reach a person.
