What Technology E&O Insurance Requirements Apply in Washington?
RCW 4.16.040 gives six years for an action upon a contract in writing, or a liability express or implied arising out of a written agreement, except as provided in RCW 64.04.007(2). The same section gives six years for an action upon an account receivable, defined as any obligation for payment incurred in the ordinary course of the claimant’s business or profession, whether arising from one or more transactions and whether or not earned by performance. RCW 4.22.070 makes each defendant’s liability several only, and not joint, except where persons acted in concert or one is an agent or servant of the other, and except where a fault-free claimant’s judgment defendants are jointly liable for the sum of their proportionate shares. A signed technology agreement uses the six-year writing period unless the real-estate exception applies. A negligence injury uses the several-liability rule. Policy notice is a third clock.
What Is Tech E&O Insurance?
Technology errors and omissions coverage can help pay when a customer claims your software, hosting, installation or technology advice caused financial loss. If you provide tech products or services, check each activity; cyber incidents and unrelated professional work need separate review. Read the national Technology errors and omissions (E&O) guide.
What Should You Watch for With Tech E&O Insurance in Washington?
The six-year contract period is for a writing, with a real-estate exception
Subsection (1) reaches a contract in writing and a liability express or implied arising out of a written agreement. It excepts what RCW 64.04.007(2) provides. An oral change order is not subsection (1). A master services agreement and a signed statement of work are. The 2012, 2007, and 1989 amendments are noted on the section. Do not treat the six years as the E&O retroactive date. 1
Unpaid invoices can be an account receivable even before the work is earned
Subsection (2) defines an account receivable as any obligation for payment incurred in the ordinary course of the claimant’s business or profession, whether from one or more transactions and whether or not earned by performance. A technology firm’s unpaid invoices can be this action. The notes say the 2007 change applies to causes of action on accounts receivable whether commenced before or after July 22, 2007. The filing period still does not satisfy a policy notice condition. 1
Joint liability is the exception; a fault-free claimant can collect all shares
RCW 4.22.070(1) states that liability of each defendant shall be several only and shall not be joint, except the cases the subsection lists. Responsibility for another’s fault arises where both acted in concert or where one is the agent or servant of the other. A claimant who is free of fault can hold the judgment defendants jointly liable for the sum of their proportionate shares. Subsection (2) addresses contribution between jointly liable defendants and the effect of a settlement. Read that subsection before you assume one insured owes only its percentage. 2
Which Tech E&O Insurance Providers Have Washington License Records?
These providers publish a national listing for Technology errors and omissions (E&O); the license records below name the licensed entities and roles. Some records rely on company-reported information rather than independent regulator verification. A national listing does not confirm the product is available in Washington. Check the regulator’s license lookup and confirm state availability for your business when requesting a quote.
At-Bay
At-Bay Insurance Services LLC
At-Bay’s license page lists P&C producer and surplus-lines broker license numbers for all 50 states and the District of Columbia. These are company disclosures and do not establish product availability in each jurisdiction. 8

Corgi
Corgi Insurance Services, Inc.
Corgi’s company producer-license table lists 50 jurisdictions: 49 states and the District of Columbia, including DC license 3003091619.

The company-reported table has no stated as-of date and does not establish product availability. 10

Risklytics

TechInsurance
Specialty Program Group LLC
TechInsurance’s current licensing page names Specialty Program Group LLC / SPG Insurance Solutions and lists state license numbers, but labels Rhode Island “Individual licenses” rather than identifying a license for the named agency. RI is omitted because this disclosure does not establish agency authority there; this is a search limitation, not an assertion that the company is unlicensed. The remaining state entries are company-reported and are not an insurance product availability map. 14
TechInsurance arranges technology errors and omissions and cyber coverage for technology businesses.
Vouch
Vouch Specialty Insurance Services, LLC
Vouch’s licenses page, effective January 16, 2025, lists producer licenses in all 50 states and DC. Its separate surplus-lines table includes Idaho number 870820, while a footnote says Georgia and Idaho do not issue agency-level surplus-lines licenses. Because those statements conflict for Idaho, this record keeps Idaho producer-only and does not treat the table number as established agency surplus-lines authority. The page is company-reported and does not establish product availability. 15
Vouch lists technology errors and omissions among the core coverages in its technology-company programs.
