5 Contract Mistakes That Cost Startups Thousands

Startups Move Fast. Contracts Shouldn't Be an Afterthought.

When you're building a product, hiring your first employees, and trying to land your first customers, contracts feel like paperwork that slows you down. So you skip them, or rush them, or use a template you found on Google without reading it properly.

Then, six months later, something goes wrong. A co-founder leaves. A client refuses to pay. A contractor claims ownership of your code. And suddenly, that contract you didn't bother with is the most important document in your business.

Here are the five contract mistakes we see startups make over and over again — and how to avoid each one.

Mistake #1: The Verbal Agreement

"We shook hands on it." "We agreed over email." "Everyone knows what the deal is."

Until they don't. Verbal agreements are technically enforceable in the UK, but proving what was agreed is nearly impossible. When memory fades and incentives change, you need a written record.

The fix: Get it in writing. Every time. It doesn't need to be a 20-page legal document — a clear one-page agreement covering scope, payment, and timeline is infinitely better than nothing. Send it for e-signature the same day you agree on terms.

Mistake #2: Unsigned Agreements

This one is more common than you'd think. A startup drafts a perfectly good contract, emails it to the other party, and... never follows up on the signature. The project starts, work gets done, money changes hands — all without a signed agreement.

An unsigned contract is barely better than no contract at all. If there's a dispute, the other party can simply say they never agreed to those terms.

The fix: Make signing frictionless. If signing requires printing, scanning, and emailing back, people will procrastinate. Use e-signatures — send a link, they click and sign in their browser. No excuses, no delays. Tools like SignVow make this free for up to 10 documents a month.

Mistake #3: Missing IP Assignment Clauses

Here's a scenario that keeps startup lawyers up at night: you hire a freelance developer to build your MVP. They do great work. Six months later, they claim they own the code because your contract didn't include an IP assignment clause.

Under UK law, the default position for freelancers and contractors is that they own the IP they create unless there's a written agreement saying otherwise. This is the opposite of employees, where the employer typically owns work product by default.

The fix: Every contractor agreement must include an explicit IP assignment clause. The language doesn't need to be complicated: "All intellectual property created under this agreement is assigned to [Company Name] upon creation." Have your lawyer review it once, then use it in every contractor engagement.

Mistake #4: No Termination or Exit Clauses

Everything is great when a business relationship is working. Nobody thinks about what happens when it stops working. But relationships do end — clients pivot, contractors underperform, partnerships dissolve.

Without clear termination clauses, you can end up stuck:

• Locked into a vendor contract with 12 months remaining and no exit clause
• Unable to fire a contractor without paying out the full contract value
• Arguing about who owns what when a co-founder leaves
• Paying for services you no longer need because the cancellation terms are ambiguous

The fix: Every contract should answer three questions: How can either party end this? How much notice is required? What happens to work-in-progress, payments, and IP when it ends? Address these upfront, while everyone is still friendly.

Mistake #5: No Audit Trail

You have a signed contract. Great. But can you prove when it was signed? Can you prove the signer actually saw the document before signing? Can you prove the document wasn't modified after signing?

If you're relying on email attachments and scanned signatures, the answer to all of these is "probably not." And in a legal dispute, "probably not" is expensive.

The fix: Use a signing platform that creates a proper audit trail. A good audit trail records:

• When the document was sent
• When the recipient opened it
• When they gave consent to sign electronically
• When they signed
• Their IP address and browser at each step
• A hash of the original document to prove it wasn't altered

This isn't paranoia — it's basic due diligence. Every serious e-signature platform provides this automatically.

The Common Thread

Notice a pattern? All five mistakes share the same root cause: friction. Contracts feel like a hassle, so founders skip steps, cut corners, or procrastinate. The solution isn't to become more disciplined — it's to make the process so easy that cutting corners is harder than doing it properly.

That means:

• Having template contracts ready for your most common scenarios (client engagement, contractor agreement, NDA)
• Using e-signatures so sending and signing takes minutes, not days
• Making it a rule: no work starts without a signed agreement

"The best time to sort out your contracts was before you started your company. The second best time is today."

Getting Started

You don't need a law firm on retainer to fix these issues. Here's a practical starting point:

1. Get templates. Have a lawyer draft (or review) three templates: a client services agreement, a contractor agreement with IP assignment, and an NDA. This is a one-time cost.
2. Set up e-signatures. Choose a tool that's free and frictionless. Upload your templates, save them, and use them every time.
3. Make it policy. No work starts, no money changes hands, no code gets written without a signed agreement. No exceptions.

It takes an afternoon to set up and saves you from the kind of disputes that cost thousands in legal fees and months of stress. Your future self will be very glad you did.
