What Is Mylo Insurance?
Mylo suits small businesses wanting online quote comparisons or licensed-advisor help; firms needing complex program management should compare full-service brokers. Mylo says 95% of customers pay no fee, though some transactions carry fees. 4,5
What Is Professional Errors and Omissions (E&O) Insurance?
Professional liability can help pay defense costs and covered losses when a client says your advice or service caused financial harm. If customers rely on your work, list every service you provide and check the claims-made reporting and prior-work terms. 8,9,10,11
Key Differences in Professional Liability (E&O) Insurance
Coverage trigger and limit
Mylo explains that E&O can be written claims-made or occurrence and that tail coverage may extend reporting after a claims-made policy ends. It compares quotes from multiple business insurers rather than underwriting the policy. Markel describes miscellaneous E&O for selected small businesses, noting revenue up to $5 million and a $2 million maximum, but the reviewed claim does not specify its trigger or tail. If changing carriers, compare retroactive dates and reporting extensions with the quoted limit. 6 3
Professional types and terms
Mylo markets this line to businesses from app development and financial planning to beauty services and describes bodily injury, property damage, financial loss and consequential-damage claims arising from client relationships. Markel describes miscellaneous E&O for professional-services claims and its targeted small-business market. Ask each to map your service agreement and requested damages to the policy definition. 6 3
What to Confirm in Professional Liability (E&O) Insurance Quotes
- Ask Mylo which carrier and trigger its quote uses, and whether the proposed retroactive date and tail meet your needs.
- Ask Markel what claims-made or occurrence form it offers, available limit and eligible professional classes.
