Key Differences in Professional Liability (E&O) Insurance
Which Professional Work Is Named
TechInsurance says its E&O policies are claims-made: the policy must be active when the incident happens and when the claim is filed. MMA’s overview does not state whether its professional lines are claims-made or occurrence-based, so buyers comparing older work need to establish the retroactive date and reporting options in each quote. 3 7
Placement Scope and Buying Route
TechInsurance gives a median premium of $88 per month and says price depends on profession, limits, deductible, staff, claims history, and income. MMA publishes no universal price or limit in the reviewed overview; compare actual premiums with the limits and retentions offered. 3 7
