## At-Bay vs TechInsurance Professional Liability (E&O) Insurance Summary

TechInsurance publishes a company-reported $88 median monthly premium; At-Bay publishes a $5 million MPL ceiling, giving buyers different screens before requesting a quote. [5](https://www.techinsurance.com/errors-omissions-insurance "Errors & Omissions (E&O) Insurance") [1](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite")

## What Are the Key Differences Between At-Bay and TechInsurance Professional Liability (E&O) Insurance?

### A Published Price Versus a Published Limit

TechInsurance puts a number on the table up front:

TechInsurance says its E&O policyholders pay a median of $88 per month, or $1,051 a year, with the exact premium depending on location, profession risk level, coverage limits, deductible, employee count, claims history and annual income. [5](https://www.techinsurance.com/errors-omissions-insurance "Errors & Omissions (E&O) Insurance") (Evidence: Company-reported; scope: Errors and omissions product page cost section; a company-reported median from TechInsurance's own book of business, not a published rate table..)

At-Bay answers a different question on its own page. Instead of a price, it publishes a limit ceiling of up to $5 million for Miscellaneous Professional Liability (MPL). [1](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite")

So a buyer comparing the two sees what TechInsurance's typical customer pays, but has to ask At-Bay separately what a policy at that $5 million ceiling would actually cost.

### Who You're Actually Buying From

TechInsurance arranges E&O as a standalone policy for businesses that provide professional services or advice, sold directly to that business. [5](https://www.techinsurance.com/errors-omissions-insurance "Errors & Omissions (E&O) Insurance")

At-Bay instead distributes MPL through its own disclosed producer, At-Bay Insurance Services LLC. Its product page is aimed at licensed insurance professionals submitting business, not a retail buyer going it alone. [1](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") [2](https://www.at-bay.com/licenses/ "Licenses")

That difference matters for how you'd actually start: a direct online purchase versus a submission through a producer.

### Keeping Past Work Covered

TechInsurance recommends keeping an E&O policy active, or setting a retroactive date, so that work performed before the current policy started stays covered under its claims-made structure. [5](https://www.techinsurance.com/errors-omissions-insurance "Errors & Omissions (E&O) Insurance")

At-Bay's page names a different set of mechanics already built into MPL, including an 80/20 hammer clause for settlement disputes, without a comparable discussion of retroactive dates. [1](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite")

## What Should You Confirm in At-Bay and TechInsurance Professional Liability (E&O) Insurance Quotes?

- Ask TechInsurance how your specific profession, location, and claims history would move the premium away from its published median. [5](https://www.techinsurance.com/errors-omissions-insurance "Errors & Omissions (E&O) Insurance")
- Ask At-Bay directly which insurer would issue your MPL policy, since the product page does not name one. [1](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite")
- Ask TechInsurance which insurer would issue your policy, since its page does not name one either. [5](https://www.techinsurance.com/errors-omissions-insurance "Errors & Omissions (E&O) Insurance")
- Ask At-Bay for its published $5 million limit ceiling and any state restrictions that apply to your business. [1](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite")
- Confirm whether TechInsurance can set a retroactive date that covers your past work before you switch from a prior policy. [5](https://www.techinsurance.com/errors-omissions-insurance "Errors & Omissions (E&O) Insurance")
