The ₦15 Million “Misunderstanding”: Why Proper Business Documentation Matters

“We’ve been friends for years. We don’t need a formal contract.”

It sounds harmless. In fact, many business relationships in Nigeria begin this way. Two friends agree on a deal, business partners shake hands, or a client and consultant reach an understanding over a phone call. Everyone trusts each other, so putting everything in writing seems unnecessary.

Until something goes wrong.

A handshake may build a business relationship, but when a dispute arises, proper documentation can make the difference between a quick resolution and a long, expensive legal battle.

Consider a recent situation involving a high-value consultancy project worth millions of naira.

The consultant had successfully completed a major project for a client and expected to receive the outstanding 70% of the agreed professional fee. Instead, the other party refused to pay, arguing that a significant part of the work carried out was outside the original scope of the engagement.

What initially appeared to be a simple disagreement quickly became a serious payment dispute.

Without proper documentation, the matter could easily have turned into a classic “he said, she said” situation. The consultant could insist that the work had been agreed upon, while the client could maintain that the additional work was never authorised. If neither party could produce reliable evidence, resolving the dispute could become considerably more difficult.

Fortunately, this consultant had maintained a proper documentation process from the beginning.

The original onboarding brief clearly set out the scope of the consultancy services. The approval emails showed that the client had reviewed and approved the various stages of the work. Most importantly, there was a signed variation note documenting the additional work, showing that it had been requested and separately priced.

The documents told the story clearly.

Rather than relying on verbal recollections or arguments about what had supposedly been agreed, the parties could look at the written records. The evidence demonstrated what the original agreement covered, what had subsequently been requested and what had been approved.

A formal demand was then issued, setting out the position and attaching the relevant documentation.

The dispute was settled within 48 hours.

The outstanding payment was cleared within two business days, without the need for prolonged litigation.

This is one of the reasons business documentation is so important in Nigeria. Contracts, emails, invoices, approval records, meeting notes, variation agreements and other business documents are not merely administrative paperwork. They can become crucial evidence when a disagreement arises.

Why Verbal Agreements Can Become Risky

It is important to understand that not every contract must necessarily be written to be legally binding. Depending on the nature of the transaction and the applicable law, a contract may be formed through oral agreement or conduct.

The real problem, however, is often proving exactly what the parties agreed.

People remember conversations differently. Circumstances change. Business relationships deteriorate. A person who readily agreed to something six months ago may have a very different recollection when a substantial payment becomes due.

Written documentation reduces that uncertainty.

A properly drafted contract can establish the parties’ obligations, payment terms, scope of work, timelines, deliverables and consequences of breach. Where circumstances change, a written variation or amendment can record the new agreement instead of leaving the parties to rely on memory.

Even emails and other business correspondence can become valuable records of what was discussed, approved or agreed.

Documentation Can Protect More Than Your Money

Proper documentation is not simply about preparing for a lawsuit.

It can prevent disputes from arising in the first place.

When both parties have a clear written understanding of their obligations, there is less room for confusion about what was promised, what has been delivered and what remains outstanding.

This is particularly important for consultants, contractors, service providers, suppliers, business partners and companies handling high-value transactions.

For example, if a client requests additional services outside the original scope of a project, the safest approach is not to rely solely on a verbal conversation. The additional work should be documented, including its cost, scope and any effect on the original timeline.

That simple step can prevent an “I never agreed to that” argument later.

Your Business File May Become Your Best Evidence

The ₦15 million dispute illustrates a simple but important business lesson: trust and documentation are not opposites.

You can trust your business partner, client or friend and still put your agreement in writing.

In fact, proper documentation can help preserve business relationships because it removes unnecessary uncertainty. Instead of arguing over what someone remembers saying months earlier, the parties can refer to the records.

A well-organised business file should tell the story of a transaction from beginning to end: how the relationship started, what was agreed, what was changed, what was delivered, what was approved and what was paid.

When a dispute arises, that record can be invaluable.

The goal is not to assume that every business relationship will end in conflict. The goal is to ensure that if a disagreement does arise, your position is supported by evidence.

Trust may start the relationship, but documentation protects the transaction.

Before your next handshake deal, ask yourself one question: if the other party changes their story tomorrow, what evidence will you have to show what was actually agreed?

Because when millions of naira are involved, “I thought we agreed” is rarely enough.
