A few days ago, a small business owner posted on Threads that she was removing all of the AI-generated images from her website. She was transparent about it — the replacement images might not be as polished, but they would be real. One of her customers replied that she loved the teas, happened to do web design, and would gladly redo the website in exchange for a few pounds of tea. She even acknowledged the obvious: the website work was worth more than the tea, but she was happy to make the trade.
It was a genuinely lovely exchange. The kind of organic, community-driven collaboration that happens when someone builds a real brand with real customers.
I commented one thing: don’t forget the written barter agreement.
Because as warm and mutual and low-stakes this was, from a legal standpoint the two were entering into a contractual agreement. Two parties exchanging goods or services of agreed-upon value. And like any contract, what happens when something goes wrong is determined entirely by what was documented before the work began.
Why a Handshake Barter Creates Real Legal Exposure
The informality of barter arrangements is exactly what makes them legally risky. When money changes hands, both parties tend to be more careful — there are invoices, payment confirmations, and a natural paper trail. When the exchange is goods for services or services for services, the transaction feels more like a favor than a business deal, and documentation gets skipped.
But the absence of documentation doesn’t change the legal nature of what happened. A barter is a contract. And an undocumented contract is an enforceable contract — it’s just an enforceable contract where the terms are whatever each party remembers them to be.
This creates three categories of exposure that business owners in barter arrangements consistently underestimate.
Disputes over scope. In a paid engagement, scope is usually defined — at least loosely — by what the invoice says. In a barter, the scope is often defined by what each party assumed at the outset. The web designer in the Threads exchange may have been thinking three pages and basic SEO. The tea company owner may have been thinking a full redesign with product photography integration. Both assumptions are reasonable. Neither was documented. When the work is delivered and one party feels the exchange wasn’t equal, the dispute isn’t about bad faith — it’s about two different understandings of what was agreed.
Disputes over value. The customer in that exchange acknowledged that the website work was worth more than the tea. That acknowledgment matters legally — it establishes that the parties understood the exchange was not equivalent in market value. But it also raises questions that a written agreement would answer: what was the agreed-upon value of each party’s contribution? Is the difference a gift, a discount, or an obligation that carries forward in some form? Without documentation, the answer depends on what each party is willing to assert.
Tax implications neither party planned for. This is the exposure most people in barter arrangements don’t see coming. The IRS treats bartered goods and services as taxable income at fair market value. If a web designer provides $3,000 worth of services in exchange for $200 worth of tea, the designer has $3,000 of taxable income — not $200. The tea company has a business expense equal to the fair market value of the web services received. Neither party in an informal barter is typically thinking about any of this when they shake hands, and the absence of documentation makes the tax accounting significantly harder to reconstruct later.
What a Written Barter Agreement Needs to Address
A barter agreement does not need to be complicated. It needs to be specific enough that both parties are operating from the same understanding — and documented enough that a third party could reconstruct what was agreed if the relationship becomes adversarial.
Here is what a complete written barter agreement should cover.
The parties and the date. Who is involved and when the agreement was made. This seems obvious, but informally arranged barters often skip it entirely.
A description of each party’s contribution. What is being exchanged, with enough specificity that “web design” and “tea” become something a stranger could evaluate. For services: what deliverables, in what format, within what timeframe, with how many rounds of revision. For goods: what product, what quantity, what quality standard, and when delivery is expected.
The agreed-upon value of each contribution. Document what each party’s contribution is worth in market terms. This is important for two reasons. First, it establishes the basis for the exchange so neither party can later claim the terms were different. Second, it creates the documentation needed for accurate tax reporting. If the values are unequal and the difference is being treated as a gift or a discount, say so explicitly.
Delivery terms and timeline. When does each party perform? Who goes first? What happens if one party delivers and the other does not? A barter arrangement where the web designer completes the site before receiving the tea is a fundamentally different risk profile than one where delivery is simultaneous. The agreement should address what constitutes performance from each party and what the timeline expectations are.
What happens if the exchange falls through. If one party cannot or does not perform, what are the remedies? Does the other party get their contribution back? Is there a cash equivalent owed? Is there a cure period — time to fix the problem before the agreement is considered breached? These are not pleasant things to think about when an exchange feels collegial and low-stakes. They are exactly the things that need to be documented before the work begins.
Intellectual property ownership. For any exchange involving creative work — web design, copywriting, photography, graphic design, content creation — the agreement should address who owns the work product once the exchange is complete. The same rules that apply to paid contractor agreements apply here. The web designer owns the work she creates unless the agreement specifically transfers that ownership. A barter arrangement doesn’t change copyright law.
Confidentiality. If either party shares sensitive business information in the course of the exchange — client data, business strategy, proprietary processes — a confidentiality provision establishes that the information stays between the parties.
The Moment It Stops Feeling Low-Stakes
Most barter arrangements feel manageable right up until the moment they don’t.
The web designer delivers a site the tea company owner doesn’t love. The tea company owner sends a variety the designer finds undrinkable. The timeline slips on one side and the other party feels the exchange is now unbalanced. Someone’s business circumstances change and the agreed exchange no longer works the same way.
None of these scenarios require bad faith to create a genuine dispute. They require only that two reasonable people had different assumptions about what was agreed — and that nothing written down can resolve the disagreement.
The written agreement doesn’t make the barter transactional. It makes it clear. Both parties still get the warmth and community of an organic exchange. What they also get is a shared understanding of what that exchange actually consists of, documented in a way that protects both of them if the relationship gets complicated.
The Barter Arrangement That Looks the Most Informal Is Often the Highest Risk
This is the counterintuitive truth about barter arrangements: the more casual and community-driven the exchange feels, the less likely either party is to document it — and the more likely an undocumented misunderstanding is to damage a relationship that both parties valued.
A barter between a business owner and a customer she genuinely likes is not low-stakes. It is an exchange between two people who have an existing relationship worth protecting. A written agreement doesn’t add distance to that relationship. It protects it.
The Threads exchange was a perfect illustration of what barter looks like in practice for growing businesses — organic, mutual, built on genuine appreciation. The only thing it was missing was a document that made sure both parties were starting from the same place.

If you want a template you can work from, MARKEDlegal’s Barter Agreement is available on our resource site, MARKEDlegal. It covers the essential provisions and is written for the kinds of exchanges service-based business owners actually make.
If your barter arrangement involves significant value, intellectual property, or an ongoing exchange — rather than a one-time swap — having an attorney review the agreement before you sign is worth the time. Off the Mark’s document review service starts at $550 for up to 10 pages.
