Imagine you sell frozen foods from a rented shop and a hotel wants to buy from you regularly. Their finance team asks for your CAC documents and a company account to pay into. If all you have is your personal account and a handwritten receipt, you may lose the deal. This is the situation where registering a business name earns its keep.
This guide explains how registering a business name with the Corporate Affairs Commission (CAC) works in practice, what to prepare, what can go wrong, and what to do afterwards. I haven't listed fees or timelines, because they change. Check the official site for current figures.
What CAC does and why registration matters
According to its website, the CAC was established under the Companies and Allied Matters Act (CAMA) of 1990 and the law was re-enacted in 2020. It is Nigeria's corporate registry and handles companies, business names and incorporated trustees. It also keeps a public register of registered entities and oversees compliance, including annual returns.
The CAC says registration gives you legal recognition under Nigerian law. It lets you open a corporate bank account, sign official contracts, and access government or financial services. It also makes your business verifiable to partners, clients and investors.
Registration is not a business plan, and it does not bring customers. It is a foundation. A registered business with no sales is still a business with no sales.
Business name or limited company?
Most small traders, caterers, tailors and shop owners start with a business name (sometimes called an enterprise). A limited company is a separate structure with directors, shareholders and more reporting. Here is a rough comparison of the general idea. Confirm details with the CAC or a licensed adviser.
| Point | Business name | Limited company |
|---|---|---|
| Best for | One owner or a small partnership, simple trade | Growing firms, outside investors, larger contracts |
| Structure | Business is closely tied to the owner | Company is a separate legal person |
| Paperwork | Lighter | Heavier, with more compliance |
| Typical start | Most first-time sellers | When you have partners, investors or big clients |
If you are testing an idea with a few thousand naira of stock, a business name is usually enough. You can move to a company later.
Before you start: what to prepare
- Two or three name options. Your first choice may already be taken or too close to an existing one.
- A clear description of what you do. Registration asks for your line of business, so decide it in plain words.
- Your business address. Use a real address where you can receive correspondence.
- Your personal details, including your NIN and a valid ID. Use only your own. Never register with someone else's identity.
- A passport photograph and signature, as requirements commonly include these. Check the portal for the current list.
- A working phone number and email that you control, since updates and documents are sent there.
Step-by-step: registering a business name
- Go to the official site. Type cac.gov.ng into your browser yourself. Don't follow links from WhatsApp or social media, because fake registration sites exist.
- Search your names. The homepage offers a business search and a name generator. Search each option to see whether something similar is already registered.
- Pick the right type. Choose business name registration rather than company or incorporated trustees.
- Fill in the form carefully. Enter your details exactly as they appear on your ID. A spelling mismatch is a common reason for delays or later problems with banks.
- Upload documents. Use clear scans or photos, not blurry shots taken in a dark room.
- Pay through the official portal. Pay only the amount shown on the platform and keep the receipt.
- Wait for review. If the CAC queries something, respond quickly and exactly as asked.
- Download and save your certificate. Keep a digital copy in email and cloud storage, and print one copy.
Using an agent
The CAC site lists accredited or trusted agencies. If you are not comfortable with the portal, using one is reasonable. Confirm the agent on the official site, ask for the total price in writing, and make sure the business is registered in your name with your email attached. Never hand over your NIN to someone you found in a random comment section.
A hypothetical example
Say Ada sells baked snacks in Enugu and wants to supply an office canteen. These numbers are made up to show the thinking, not to quote real fees.
- She assumes registration, agent help (if any) and a few printed copies cost ₦A in total.
- She assumes a corporate account needs a small opening deposit of ₦B.
- The canteen contract is worth ₦C a month in gross sales.
Her question is simple: will ₦C over a few months clearly cover ₦A plus ₦B plus the cost of the stock? If the canteen order is only a possibility, she might wait or start with a smaller test. Get current quotes from the CAC portal, your bank and an agent before putting real numbers in.
After registration: what many people skip
- Open a business account. Banks usually ask for your certificate and ID. Requirements differ by bank, so ask before you go.
- File annual returns. The CAC lists oversight of annual returns and compliance among its functions. Missing them can lead to trouble, so put a reminder in your calendar and confirm the current rules on the portal.
- Update changes. If you move or change your details, the CAC offers post-incorporation services such as changes in company information.
- Think about tax. Registration and tax are separate matters. Ask the relevant tax authority or a licensed accountant what applies to you.
- Check sector permits. Food, drugs, cosmetics, transport, and similar trades often need extra approvals from other agencies, and local governments may charge levies. The CAC certificate doesn't replace them.
Common mistakes
- Choosing a name first and printing signage later. Printing banners before approval can mean paying twice.
- Using a name too close to a famous brand. It may be rejected or cause legal problems later.
- Mixing personal and business money. A certificate won't fix this. Keep simple records; see our bookkeeping guide for a small shop.
- Paying for guaranteed approval. Nobody can honestly guarantee it. Treat that claim as a red flag.
- Treating registration as the finish line. Many businesses fail on cash flow and pricing, not paperwork. Read why small businesses fail and how to price for profit.
How it differs by situation
If you trade informally in a market and your customers are individuals, registration may not be urgent. If you want corporate clients, bank loans, grants or tenders, it often is. If you run a POS outlet, you also need approvals beyond CAC; see our POS business guide. Readers in Ghana, Kenya and South Africa should note that CAC covers Nigeria only; each country has its own registry.
Frequently asked questions
Do I need a registered business to start selling?
Not always. Many people test an idea first. Register when clients, banks or platforms ask for proof, or when you are ready to separate business from personal finances.
Can I check whether a business is registered?
Yes. The CAC homepage has a search for existing businesses. Use it before paying a supplier or partner who claims to be registered.
Is a business name the same as a company?
No. A company is a separate legal entity with more obligations. Ask a licensed adviser if you are unsure which fits.
Can I register from abroad?
The process is online, but requirements for identity and address may apply. Check the portal or an accredited agency for current rules.
Your next step
Write down three possible names and your one-line business description, then search each on the CAC homepage today. That costs nothing and tells you whether you are ready to move forward.
