Key takeaway: Informal business agreements — verbal commitments, texted agreements, "we'll figure it out" arrangements — create gaps that insurance policies are not designed to fill. When work is performed without a written contract, you lose more than legal standing in a dispute. You may lose the coverage you thought you had. This applies to Spokane service businesses, contractors, freelancers, vendors, and any small business that regularly works with clients or subcontractors on trust.
Most small business owners who get burned by an informal agreement say the same thing: "We've worked together for years. I didn't think I needed something in writing."
That's exactly when it happens.
A general liability policy covers a lot. A professional liability policy covers a lot more. But both of them are built around a foundational assumption — that there was a defined scope of work, a clear understanding of who was responsible for what, and some documented basis for what was promised. When that foundation doesn't exist, the claim gets complicated fast. Sometimes it gets denied.
This is not a scare tactic. It's what actually happens in disputes where the paper trail ends at a text message from four months ago.
Outline
What "Informal Agreement" Actually Means in a Business Context
An informal agreement is any arrangement between two parties where the terms — scope, price, timeline, liability, deliverables — were not put in writing and signed by both sides. That includes verbal agreements, text exchanges, email threads that were never formalized, and handshake deals at the end of a job site walkthrough.
Oral contracts are technically enforceable under Washington State law. The problem isn't legality. The problem is proof. When a client says you promised to include something you never agreed to include, or when a subcontractor says you owe them for work outside the original scope, the dispute becomes your word against theirs. Without a written agreement, neither party has documentation of what was actually agreed. That means any resolution — whether through negotiation, mediation, or litigation — starts from scratch. And if insurance is involved, the carrier's first question is going to be: what did the contract say?
If the answer is "there wasn't one," that's where the conversation gets difficult.
The Most Common Places Spokane Businesses Skip the Written Contract
Service businesses and subcontractor arrangements
A landscaping company that brings in a part-time crew during the summer. A cleaning service that hires a friend to cover overflow accounts. A general contractor who regularly uses the same plumber without updating a subcontractor agreement. These relationships feel stable because they've worked before. The written agreement gets treated as a formality that no one gets around to completing.
Then someone gets hurt on the property. Or the subcontractor damages something. Or the work isn't finished and the client wants their money back. Suddenly the question of who was responsible for what matters a great deal — and there's no document that answers it cleanly.
Vendor relationships and recurring supplier deals
A restaurant that orders from the same food supplier on a verbal understanding of price and delivery terms. A retail shop that stocks product on a handshake consignment deal. A property manager who uses the same HVAC company without a formal service agreement in place. Routine relationships tend to stay informal the longer they go on, because nothing has gone wrong yet.
When something does go wrong — wrong delivery, damaged product, a billing dispute — the lack of a written agreement means the dispute defaults to whoever can produce the most documentation. That's usually the larger party.
Side work and referral-based jobs
In Spokane's small business community, a lot of work comes through word of mouth. Someone calls a contact, describes what they need, gets a number, and the job gets done. The invoice goes out after the fact. Nobody signed anything. For low-dollar, low-stakes work, this is usually fine. For anything involving property, professional judgment, or physical labor where an injury or mistake could occur — it's a real exposure.
What Happens When a Dispute Has No Paper Trail
A dispute without documentation doesn't just go to court. It goes through every uncomfortable stop before court: the frustrated phone call, the threat of a bad review, the demand for a refund, the insurance claim notice.
At each of those steps, the other party's version of events is as valid as yours because neither of you has a document that says otherwise. That's true even if you are completely right about what was agreed. Being right and being able to prove it are different things.
The small claims court limit in Washington State is $10,000 [verify current limit — Washington Courts website]. A lot of disputes between small businesses fall under that threshold, which means they're accessible, fast, and easy to file. A former client with a grudge and no legitimate case can still cost you a day of work and a filing response just by showing up.
Above that threshold, the legal costs of proving what was agreed to — without a written contract — can exceed the value of the original job.
The Insurance Problem Nobody Talks About
Why your GL policy may not respond the way you expect
A general liability policy covers bodily injury and property damage you cause to third parties. What it does not cover is a contractual dispute about whether you completed the work you promised, whether you owe a refund, or whether your subcontractor's error is your responsibility.
Here's where informal agreements create a specific problem: if there's no written contract, it's harder to establish that you and your client had a clear understanding of scope. That matters because GL policies often include coverage for work completed — but "work completed" implies there was a defined scope. Without a contract, the carrier has less to work from when evaluating whether the loss falls inside your policy's coverage territory.
This doesn't mean your claim gets denied automatically. It means the investigation takes longer, the documentation burden falls on you, and the outcome is less predictable.
Professional liability and the contract connection
Professional liability insurance — also called errors and omissions, or E&O — covers claims that your advice, service, or professional work caused a financial loss to a client. Consultants, designers, accountants, IT professionals, and anyone who provides expertise for a fee should carry it.
E&O policies are built around the concept of a defined engagement. Who hired you? For what? What were you supposed to deliver? When a claim comes in, the carrier goes looking for the document that answers those questions. A signed engagement letter or service agreement is that document. Without one, you're describing the scope of your own work to a carrier that has every reason to ask follow-up questions.
I've seen E&O claims take months longer to resolve — and settle for less — simply because nobody could produce a clear record of what the client actually paid for.
What Washington State Says About Oral Contracts
Washington recognizes oral contracts as legally binding in most circumstances. The main exception is the Statute of Frauds, which requires written agreements for specific categories: real estate transactions, contracts that can't be performed within one year, and a handful of others.
For most small business transactions — service work, vendor agreements, subcontractor arrangements — an oral agreement can technically be enforced. The statute of limitations for written contracts in Washington is six years; for oral contracts, it's three.
That shorter window matters if a dispute surfaces later than you expect. And "legally binding" doesn't mean easy to prove. It means you have the right to try.
What a Written Agreement Actually Needs to Do (It Doesn't Have to Be Long)
A written contract doesn't need to be a multi-page legal document drafted by an attorney for every job. For most small business work, a short service agreement that covers six things will do the job:
- What is being done. Scope of work, as specifically as possible.
- What it costs. Fixed price, hourly rate, or estimate — and how changes to scope affect price.
- When it's done. Completion date or project milestones.
- Who pays for what. Materials, third-party costs, incidentals.
- What happens if something goes wrong. Dispute resolution process, limitation of liability.
- Both signatures. Dated.
That's it. A one-page document with those six elements is enforceable, produces a paper trail, and gives your insurance carrier something to work with if a claim comes in.
For larger engagements, recurring relationships, or work involving subcontractors, it's worth having an attorney review your template once. That cost is trivial compared to what a single undocumented dispute can cost.
If you're not sure whether your current agreements are protecting you — or whether the work you're doing is covered by your existing policies — that's a conversation worth having before something goes sideways.

Frequently Asked Questions
Does a text message or email count as a written contract in Washington State?
It can. Courts have found that text and email exchanges constitute enforceable agreements when they contain the key terms of a deal — scope, price, parties, and acceptance. The problem is that a thread of texts is much harder to produce cleanly in a dispute than a single signed document. If you're doing business over text, at minimum send a follow-up email summarizing the agreed terms and ask the other party to confirm.
Will my general liability insurance cover me if a client claims I didn't complete the work?
No. GL insurance covers bodily injury and property damage to third parties — not contract disputes or claims that work wasn't finished. A dispute over the quality or completeness of your work is a professional liability or breach of contract issue, not a GL claim.
What's the difference between a handshake deal and a verbal contract?
Legally, not much. Both are oral contracts, and both can be enforceable in Washington State. The practical difference is documentation. A handshake deal typically has no supporting record at all. A "verbal contract" may have been reinforced by emails, texts, or witnesses. The more supporting context exists, the stronger your position in a dispute — but neither beats a signed written agreement.
Can I use a free contract template I found online?
For simple, low-dollar work, a basic template is better than nothing. For anything involving ongoing services, physical property, subcontractors, or professional advice, have an attorney review it at least once. A template that doesn't account for Washington State law or your specific industry may have gaps you won't find until you need the contract to hold up.
Does my insurance carrier require written contracts?
Most policies don't require written contracts as a blanket condition of coverage. However, some commercial policies — especially professional liability — do require documentation of engagements as part of the claims process. And even when it's not required, the absence of a written agreement makes claims harder to investigate and slower to resolve.
What happens if a subcontractor I hired causes damage and there's no written agreement between us?
You may be held responsible. If the subcontractor was acting on your behalf, the injured party could come after you — and your GL carrier will want to understand the relationship. A subcontractor agreement that establishes scope, liability allocation, and proof of their own insurance coverage protects you. Without it, you're exposed to whatever the subcontractor's mistake costs.
How short can a service agreement be and still be legally useful?
Short enough to fit on one page. The goal isn't length — it's specificity. A half-page agreement that clearly defines scope, price, timeline, and dispute resolution is more useful than a five-page template filled with generic language. What matters is that both parties signed it and the terms are clear.
Should every small business job have a written contract?
Not necessarily. For very small, low-risk transactions — a one-time job under a few hundred dollars with someone you know well — the overhead of a contract may not be worth it. But for anything involving significant money, physical property, professional judgment, or an ongoing relationship, the answer is yes. The threshold most attorneys suggest: if a dispute over this job would affect your business or require you to get a lawyer, it needs a contract.
