5 Costly Contract Mistakes That Small Businesses Make (And How to Avoid Them)

Key Takeaways: 60% of small businesses have experienced a contract dispute that cost them money, relationships, or both. The five mistakes in this guide account for the vast majority of those disputes — and every one of them is preventable with better contract practices.

The Real Cost of Contract Mistakes#

Contract problems don't just cost legal fees. They cascade:

• Direct financial losses: An average small business contract dispute costs $11,000 to resolve (American Bar Association, 2024), not including the management time consumed
• Lost relationships: 68% of business relationships end permanently after a contract dispute
• Operational disruption: When a key vendor or client dispute goes south, the business impact extends far beyond the contract value
• Opportunity cost: The time you spend managing a dispute is time you're not spending on growing the business

Yet most small businesses don't have a lawyer on retainer, can't afford sophisticated CLM software, and rely on informal agreements or downloaded templates they barely read before sending. Here are the five mistakes that create the most damage — and practical fixes you can implement today.

Mistake 1: Working Without a Written Contract#

How often it happens: Shockingly common. A 2024 survey found that 43% of small businesses have completed work based on a verbal agreement or email — no formal contract signed.

Why it happens: The relationship feels good. You've worked together before. Writing a contract feels "too formal" or "slow." You're afraid the client will think you don't trust them.

What goes wrong:

• The client remembers agreeing to "$5,000 for the project" — you remember "$5,000 per month"
• The scope keeps expanding because neither party defined what was included
• When payment is late, you have no enforcement mechanism

Real example: A freelance web developer built a $12,000 e-commerce site on a handshake deal. The client requested 14 rounds of revisions, then disputed the final invoice because "it took way longer than expected and therefore the scope changed." Without a written contract specifying revision limits, the developer had no leverage and settled for $7,500.

The fix:

• Use a standard contract template for every engagement — no exceptions
• ZiaSign offers free, customizable contract templates you can send for signature in under 60 seconds
• Frame it positively: "I send contracts for every project — it protects both of us and makes sure we're aligned on expectations"
• For small projects, a 1-2 page agreement is sufficient. It doesn't need to be 20 pages of legalese

Mistake 2: Vague Scope of Work#

How often it happens: Even when businesses do use contracts, the scope section is often dangerously vague.

The problem statement: "Consultant will provide marketing services to Client" tells you nothing. How many hours? Which channels? What deliverables? What results are expected?

What goes wrong — scope creep:

• The client asks for "one more thing" — and keeps asking
• You feel obligated because the contract doesn't explicitly exclude added requests
• The project takes 3x longer than estimated, but the price was fixed
• By the end, both parties feel like they got a bad deal

How to write a bulletproof scope:

❌ Bad: "Design services for client's marketing needs"

✅ Good: "Design 3 social media templates (Instagram post, Instagram story, LinkedIn post) in Figma. Includes 2 rounds of revisions per template. Additional revisions billed at $150/hour. Templates delivered as source files and exported PNGs within 10 business days of project kickoff."

Elements of a strong scope:

1. Specific deliverables — numbered, named, and described
2. Revision limits — how many rounds are included, cost for additional rounds
3. Timeline — delivery dates or turnaround windows
4. Exclusions — what's explicitly NOT included (this prevents assumptions)
5. Change order process — how to add scope (written approval + adjusted pricing)

Mistake 3: No Cancellation or Termination Clause#

How often it happens: 35% of small business contracts have no cancellation provision.

What goes wrong:

• A client cancels a project halfway through, and you're left with half-finished work and no income
• A vendor ghosts you mid-project, and you have no contractual recourse
• A long-term retainer client wants to walk away with no notice

What to include:

• Notice period: 30 days' written notice for ongoing agreements
• Cancellation fees: A cancellation fee or "kill fee" that compensates for lost opportunity and work already completed
• Payment for work completed: All work performed up to the cancellation date must be paid for
• Deliverable handover: Work product completed to date is delivered upon full payment
• No penalty for cause: If one party breaches the contract, the other can terminate immediately without penalty

Mistake 4: Ignoring Intellectual Property Ownership#

How often it happens: 52% of freelancer and agency contracts don't clearly define IP ownership.

Why it matters: When you create something — a design, a piece of software, a marketing strategy, copy — who owns it? Without a clear clause, the default legal answer depends on your jurisdiction and employment classification, and it's rarely what either party expects.

Common scenarios that go wrong:

• A developer builds custom software for a client. The client assumes they own the code. The developer assumes they retain the rights to reuse components. Neither is explicitly stated.
• A designer creates a logo. The client uses it for 3 years, then discovers the designer also sold it to a competitor. The contract didn't address exclusivity.
• A company hires a contractor to write blog posts. The blogs rank well on Google. A year later, the contractor leaves and demands the content be taken down, claiming they retained copyright.

The fix — be explicit:

Upon full payment, all work product created under this agreement is assigned to Client as a "work made for hire." Client owns all rights, title, and interest in the deliverables, including copyright, trademark, and trade secret rights.

OR (if the creator wants to retain rights):

Creator retains all rights to the work product and grants Client a non-exclusive, perpetual license to use the deliverables for their business purposes. Creator may reuse, modify, or license the work to third parties.

Mistake 5: Not Getting Signatures Before Starting Work#

How often it happens: 28% of small businesses begin work before the contract is fully signed.

Why it happens: The client is eager to start. You're afraid of losing momentum. The contract is "almost ready" — you'll finalize it next week.

What goes wrong:

• You've completed 40 hours of work, and the client sends back the contract with significant changes to the payment terms
• The client decides not to move forward after you've already invested time and resources
• A dispute arises, and the client argues the unsigned contract doesn't apply

The fix:

• Make contract signing the trigger for work commencement — no exceptions
• Use ZiaSign to send and get contracts signed within hours, not days — speed removes the pressure to start before signing
• Include a clause: "Work will commence upon execution of this agreement and receipt of the initial deposit"
• If the client pushes back, frame it as protecting them: "The contract locks in your pricing and timeline — I want to make sure you're protected before we start"
