Stop Doing Business on Handshakes: Why Every Tax Professional Needs Written Agreements

If you've spent any time in tax professional groups lately, you've probably seen the posts.

"I completed the work, and they never paid me."

"They changed the agreement after the project was finished."

"They're refusing to pay the final invoice."

"They're using my work without paying for it."

Unfortunately, these stories are becoming far too common.

And almost every time I read one, I find myself asking the same question:

Was there a written agreement?

More often than not, the answer is no.

Put Everything in Writing

Every. Single. Time.

No exceptions.

I don't care if:

• You've known the person for years.

• They're a friend.

• They're another tax professional.

• They seem trustworthy.

• It feels awkward to ask them to sign something.

The moment money, services, or business expectations are involved, you need a written agreement that clearly outlines what both parties have agreed to.

A handshake may build a relationship.

A contract helps protect it.

Why Written Agreements Matter

Many business owners assume they'll never need a contract because they trust the other person.

The problem is that disagreements don't always happen because someone intended to be dishonest.

Sometimes expectations simply aren't communicated clearly.

Questions like these can quickly become points of conflict:

• What work was actually included?

• When is payment due?

• How many revisions are allowed?

• Who owns the finished work?

• What happens if the project is canceled?

• What if someone misses a deadline?

A written agreement answers those questions before they become problems.

If a Dispute Ends Up in Court

Here's something every business owner should understand.

If a disagreement ends up before a judge, the conversation usually changes from:

"But they told me..."

to

"Can you show me what was agreed to?"

Judges rely on evidence.

A written contract provides documentation of:

• The services to be performed

• Payment terms

• Due dates

• Responsibilities of each party

• What happens if someone fails to fulfill the agreement

Memories fade.

Text messages get deleted.

Phone conversations are difficult to prove.

A signed agreement tells the story.

Written Agreements Protect Both Parties

Many people think contracts exist because someone doesn't trust the other person.

That's not the purpose.

A good agreement protects everyone involved.

It establishes expectations.

It reduces misunderstandings.

It provides clarity if questions arise later.

When both parties know exactly what's expected, business relationships are often stronger—not weaker.

Documentation Can Become Valuable Evidence

There's another side to this conversation that doesn't get discussed enough.

If someone asks you to do something unethical or illegal—and they put that request in writing—that communication may become important evidence if the situation escalates.

Documentation doesn't just protect you when people honor agreements.

It can also protect you when they don't.

Create Standard Contracts for Your Business

If you regularly outsource work or provide services, don't start from scratch every time.

Develop standard agreements for common situations, such as:

• Independent contractors

• Virtual assistants

• Marketing consultants

• Tax preparation services

• Bookkeeping services

• Business coaching

• Speaking engagements

• Training programs

• Referral partnerships

Each agreement should clearly define:

• Scope of work

• Payment terms

• Deadlines

• Deliverables

• Confidentiality expectations

• Ownership of work product

• Cancellation policies

• Dispute resolution procedures

The more clearly expectations are communicated, the less room there is for confusion.

Pay Attention When Someone Refuses to Sign

Here's something I've learned over the years.

If someone immediately becomes uncomfortable with signing a reasonable agreement, pay attention.

That doesn't automatically mean they're dishonest.

However, it is information worth considering.

People who fully intend to honor an agreement rarely object to putting those expectations in writing.

Sometimes hesitation simply means they have questions.

Other times, it may be a warning sign that expectations aren't aligned.

Either way, it's a conversation worth having before work begins—not after problems arise.

Professional Businesses Operate Professionally

As tax professionals, we encourage our clients to maintain good records, document transactions, and protect their businesses.

We should hold ourselves to the same standard.

Professionalism isn't just reflected in the services we provide.

It's reflected in how we conduct business.

Contracts.

Engagement letters.

Invoices.

Policies.

Documentation.

These aren't signs that you expect problems.

They're signs that you've built a business designed to prevent them.

Final Thoughts

Good faith is important.

Trust is important.

Relationships are important.

But none of those should replace sound business practices.

Protect your time.

Protect your income.

Protect your reputation.

Protect your business.

Because the tax professionals sharing stories about unpaid invoices, broken agreements, and business disputes often have one thing in common:

Nothing was ever put in writing.

The best time to establish expectations is before the work begins.

Your future self will thank you for it.
