What Is Liberty Mutual Business Insurance?
Liberty Mutual spans small-commercial, commercial, specialty, surety, and reinsurance businesses. The insurer and distribution route depend on the product, so check the offer and policy before you compare terms. 1,2
What Is Pie Insurance?
Pie suits small businesses seeking workers’ compensation with online quoting and pay-as-you-go billing based on reported payroll, without an initial deposit; firms needing a broad technology or executive program should look elsewhere. 4,5,6
What Is Workers’ Compensation Insurance?
Workers’ compensation can pay medical care and part of an employee’s lost wages after a work-related injury or illness. If you have staff, check who is covered in each state; owners, contractors and some workers may be treated differently. 8,9,10,11
Key Differences in Workers’ Compensation Insurance
Who Underwrites and How You Apply
Pie says it underwrites workers’ compensation through its own carrier group, and its disclosure record identifies two group entities writing the line. Liberty Mutual lists workers’ compensation in its commercial catalogue and distributes products through brokers and agents, without naming the issuing insurer in the reviewed offering record. Pie also describes an online quote using business, payroll and class-code information; ask Liberty Mutual’s agent to identify its insurer and submission path. 3 5
Small-Business Services
Pie markets workers’ compensation to small businesses and says it can issue certificates of insurance and perform a post-term payroll audit. Liberty Mutual’s record does not describe comparable certificate or audit services. Confirm whether Liberty Mutual offers them and compare the treatment of estimated versus actual payroll. 3 5
What to Confirm in Workers’ Compensation Insurance Quotes
- Which Pie group entity will issue the quote and how will final payroll differ from the estimate at audit?
- Who underwrites Liberty Mutual’s offer and are certificates and payroll audits included?
