5 Things You Must Document in Your Business (Or Watch It Fall Apart)
The Head-Only Business
Let me tell you the truth: Many business owners keep everything in their head.
Nobody talks about it because it feels like strength—"I can handle everything myself."
But here's what really happens:
- Business information is scattered
- Mistakes repeat themselves
- The business becomes fragile
- Personal money and business money mix
- Nothing is steady
If you don't write things down, nothing stays stable.
The 5 Things Every Business Must Document
1. Sales Records
What to record:
- Who bought
- What they bought
- How much they paid
- When they bought
- How they paid (cash, transfer, POS)
Why it matters:
- Know your actual revenue (not guessed)
- See which products sell most
- Track who your best customers are
- Have proof for tax purposes
Simple format:
| Date | Customer | Item | Amount | Payment |
|---|---|---|---|---|
| 10/1 | Ade | Widget x2 | ₦5,000 | Transfer |
| 10/1 | Bola | Gadget | ₦3,500 | Cash |
2. Expenses and Costs
What to record:
- Every expense, big or small
- Category (transport, supplies, utilities, etc.)
- Date
- What it was for
Why it matters:
- See where money actually goes
- Without records, profits disappear mysteriously
- Find expenses to cut
- Claim proper deductions for tax
The rule: If money left your business, write it down. ₦100 or ₦100,000—record everything.
3. Stock/Inventory Levels
What to record:
- What you have
- How much of each
- Reorder level (when to buy more)
- Last count date
Why it matters:
- No stock should finish without your notice
- Know what's selling fast
- Don't tie up money in slow items
- Catch theft or shrinkage
Simple weekly check:
Count your main items every week. Compare to sales. The math should match.
4. Customer Data
What to record:
- Name
- Contact (phone/WhatsApp)
- What they usually buy
- Any feedback they've given
- Special preferences
Why it matters:
- Follow up on potential sales
- Remember returning customers
- Personalize service
- Build relationships that last
Basic customer list:
| Name | Phone | Usual Order | Notes |
|---|---|---|---|
| Ade | 0801... | Widget | Prefers delivery |
| Bola | 0803... | Gadget | Always pays cash |
5. Processes and Systems
What to document:
- How you take orders
- How you handle payments
- How you do deliveries
- How you close each day
- How you handle complaints
Why it matters:
- Work gets done the same way every time
- You can train others
- Mistakes reduce
- Business runs without you
Simple SOP format:
TASK: Taking an Order
STEPS:
1. Greet customer
2. Check stock availability
3. Quote price from price list
4. Confirm payment method

The Cost of Not Documenting
Every business that doesn't document eventually:
- Loses money without knowing where
- Runs out of stock unexpectedly
- Forgets customers and loses them
- Repeats mistakes
- Can't answer when FIRS asks questions
- Can't get loans (banks want records)
- Can't sell the business (no proof of performance)
