AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
An ice block business freezes clean water in nylon bags or moulds and sells the blocks to drink sellers, fish and meat traders, event caterers and households. The set-up is a few chest freezers and a clean water source, but power is the main daily cost: with Band A at ₦209.50 per kWh under NERC's July 2025 order for Ikeja Electric and petrol at an NBS average of ₦1,596.25 a litre in May 2026, generator hours decide whether a day makes money.
How the business works
Ice block sellers fill nylon bags or plastic moulds with water, freeze them overnight in chest freezers, and sell the blocks the next day. Buyers include drink and water sellers who chill bottles, fish and meat traders, event caterers, bar and lounge owners, and households during hot spells or power cuts. Demand is usually highest in the hottest months and around festive seasons and weekends with many events; it can fall away in cool, rainy spells.
Start-up cost: an example
Freezer prices vary by size and brand. This is an example; get quotes.
| Item | Example cost |
|---|---|
| Two large chest freezers | ₦1,400,000 |
| Petrol generator (backup) | ₦450,000 |
| Stabiliser and wiring | ₦120,000 |
| Water storage tank and filter | ₦200,000 |
| Nylon bags, sealer, cooler box | ₦60,000 |
| Total (example) | ₦2,230,000 |
Rent depends on where you operate; many start from home or a shop front with good access for buyers.
Water quality
Ice often touches food and drinks, so dirty water makes people ill. NAFDAC's guideline for packaged water facilities gives an idea of the standard it expects for water sold for consumption: a borehole of at least 150 feet with no dug wells, a water source at least 30 metres from any septic tank, treatment such as chlorination, reverse osmosis or ozone, and UV treatment before filling, plus medical tests for food handlers. That guideline is written for sachet and bottled water, not ice. Ask NAFDAC whether your ice needs registration before selling branded or packaged ice, and use treated, filtered water either way.
- Clean freezers, moulds and storage tanks on a schedule.
- Use new, food-grade nylon; reused bags carry dirt.
- Wash hands and wear clean gloves when bagging.
- Keep the area around the freezers dry and free of pests.
Power: the cost that decides profit
A freezer making ice works harder than one storing frozen food, because it has to remove heat from fresh water every day. Read the energy label on each freezer and measure real usage if you can.
Worked example: one day
This is an example with assumed figures.
| Line | Assumption | Amount |
|---|---|---|
| Blocks produced | 2 freezers × 40 blocks | 80 blocks |
| Sales | 80 blocks at ₦300 | ₦24,000 |
| Grid power | 2 freezers × 4 kWh = 8 kWh at ₦209.50 | ₦1,676 |
| Generator backup | 3 hours at 1.2 litres an hour = 3.6 litres at ₦1,596.25 | ₦5,746.50 |
| Water | ₦1,500 | |
| Nylon | ₦800 | |
| Total daily cost | ₦9,722.50 | |
| Daily profit if all blocks sell | ₦24,000 − ₦9,722.50 | ₦14,277.50 |
Two sensitivities matter. If power is poor and the generator runs six hours instead of three, fuel doubles to ₦11,493 and profit falls to ₦8,531. If only 60 blocks sell, revenue drops to ₦18,000 and profit to ₦8,277.50, and you hold 20 blocks that will need freezer space tomorrow. The grid tariff is from NERC's July 2025 Ikeja Electric order; check your own DisCo's tariff and band, and today's pump price.
Seasonal demand and planning output
Ice demand is not steady through the year. Many sellers find the hottest months and the run-up to festive periods busy, and cool, wet weeks slow. Plan for it rather than being caught out.
- In busy months, run every freezer at full output and take event orders early.
- In slow months, cut production to what regular buyers take and switch off a freezer rather than making blocks nobody buys.
- Use idle freezer space in slow months to store frozen goods for a neighbouring trader for a fee, if your hygiene allows it.
- Service freezers and the generator in the slow season so they do not fail in the busy one.
Keep a simple daily log of blocks made, sold and left, and the hours of grid and generator supply. After a few months it shows which days and seasons pay, and when you are running the generator for blocks that do not sell.
Pricing per block and finding buyers
- Check what other ice sellers near you charge by size, and price clearly per size.
- Offer a slightly lower price for regular bulk buyers such as fish traders and drink sellers who collect every day.
- Take event orders in advance and charge for delivery separately.
- On hot days with long power cuts, demand rises; make sure you have stock rather than raising prices sharply on regulars.
Some frozen foods shops add ice to use spare freezer space; see frozen foods shop start-up cost. The planned guide to the sachet water factory covers the related water trade.
What to check first
- Your feeder band and typical supply hours.
- Water source and treatment, and whether NAFDAC rules apply to your product.
- Five or more regular buyers within easy reach.
- Freezer energy use and generator fuel use per hour.
- A daily record of blocks made, sold and left over; see bookkeeping for small businesses.
Where Pryme fits
Prepaid meters can be topped up through electricity payments in the Pryme app, and regular buyers can settle weekly into a Pryme Business Account.
Questions people ask
How much do I need to start an ice block business?
Two chest freezers, a backup generator, water storage and bags came to ₦2,230,000 in our example. You can start with one freezer, but output falls with it.
How much profit can I make from ice blocks daily?
It depends on power and sales. In our example 80 blocks at ₦300 left about ₦14,000 profit, falling to about ₦8,000 with longer generator use or fewer sales.
Is ice block business profitable in Nigeria?
It can be in hot months and areas with good grid supply. Heavy generator use and weak demand in cooler months are the main risks.
Do I need NAFDAC to sell ice blocks?
Ask NAFDAC whether your product needs registration, especially for branded or packaged ice. Use treated, filtered water either way.
