You have decided to start a business. You have the idea, the capital, maybe even your first customer lined up. The next legal step is registering with the Corporate Affairs Commission (CAC) and this is where many entrepreneurs, in their excitement, make mistakes that come back to haunt them months or years later.

Registration itself is now largely digital because the registration is done online and the documents come in softcopy and fairly straightforward. But “straightforward” does not mean “risk-free.” Below are the mistakes I see most often, and what to do instead.

1. Registering a Business Name instead of a limited liability company

Many new entrepreneurs default to a Business Name because it is cheaper and faster. What they don’t realize is that a Business Name has no separate legal identity from its owner meaning if the business runs into debt or a lawsuit, your personal assets (your car, your savings, sometimes your house) can be on the line. A Limited Liability Company, by contrast, is a separate legal person, it means the company can be sued, can owe debts, and can be liquidated without automatically dragging your personal property into it. If you are planning to raise investment, sign serious contracts, or simply want to protect your personal assets, don’t default to a Business Name just because it is the easier option or the cheap option.

2. Choosing a name without a backup and without checking it properly

CAC will reject a proposed name that is identical or too similar to an existing registered name, or that contains restricted words. Many founders submit only one name option, get rejected, and lose time and money starting the process again. Always submit a unique name, and avoid names that closely resemble big or well-known brands. It can be frustrating getting to know that the name you are known with is already taken.

3. Submitting incomplete or mismatched identification details

Since the CAC portal is now tied into the National Identity Management Commission’s database, every director or proprietor’s National Identification Number (NIN) must match their other documents exactly: names, dates of birth, everything. A small mismatch between your NIN details and your registration form is one of the most common causes of delay and query. Before you start, confirm that your NIN slip and your ID documents say exactly the same thing.  This mismatch even if it scales through CAC, it will affect your bank account opening process. I have clients who have come back to edit their details on CAC portal because of identification mismatch.

4. Treating the certificate as the finish line

This is perhaps the costliest mistake. Many people treat the CAC certificate as the end of the process, when it is really just the starting point for a new set of legal obligations:

1. Appoint auditors within six months of incorporation
2. Hold your first Annual General Meeting within 18 months of incorporation
3. File annual returns every year to confirm your company is still active

Skip these, and the CAC can strike your company off the register which means the “registered business” you worked hard to set up quietly stops legally existing, often without you even realizing it until you try to use the certificate for something important. Recently CAC has struck out many businesses from their register as a result of inactivity. CAC can be lenient in some cases but the leniency comes with penalty. To avoid any of these, do the needful as at when due.

5. Poor quality documentation on the portal

Because registration is now done entirely online, the accuracy and clarity of the documents you upload matters more than ever. Blurry scans, inconsistent formatting, or a personal email address instead of a professional one can slow down or sink your application. Keep clean digital copies of every document in PDF or JPEG format, and use a professional email address tied to your business name to avoid update on post incorporation as that can cost time and money.

6. Underestimating Share Capital

Many entrepreneurs register with the bare minimum share capital just to save on fees, without thinking about how this looks later. If you ever bid for a serious contract or approach investors, a company registered with the bare minimum can look weaker on paper than one that reflects real ambition. Share capital is not just a formality, it is a signal of your company’s scale, and it’s worth thinking through with proper advice rather than defaulting to the smallest figure allowed. Also note that the company yearly annual returns will be determined by the share capital. If your share capital is high, your annual returns will be high also.

7. Skipping professional guidance for complex structures

CAC’s self-service portal genuinely allows individuals to register a Business Name or simple company themselves. But once foreign ownership, higher share capital requirements, or an NGO/Incorporated Trustee structure is involved, the requirements multiply and mistakes at this stage are far more expensive to fix than the cost of proper guidance would have been. If your structure isn’t the simplest case, don’t gamble on a DIY registration. A client once hit the rock as she tried to register her company by herself and joined ordinary shareholder and preference shareholders together which ought not to be. Do not fall into the temptation of wanting to do your registration by yourself. Seek professional guidance to avoid double cost.

In conclusion, CAC registration is not just paperwork it is the legal foundation your entire business stands on. A mistake at this stage does not just cost you time; it can expose your personal assets, delay your account opening process, incur unnecessary penalties for yourself or even see your company struck off the register without your knowledge. Get it right from the start, and it becomes a one-time process that opens doors. Get it wrong, and it becomes a recurring, expensive problem.
