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
A water tank dealer buys tanks from a manufacturer or distributor at a trade price and resells them, usually with delivery, to households, builders and estates. In our labelled example, selling 18 tanks a month across three sizes earns about ₦400,000 gross and about ₦160,000 after delivery, rent and staff, on stock worth about ₦2.6 million. Delivery and stock space decide whether the business pays.
How a tank dealership works
Plastic water tanks are bulky, light and awkward to transport, which shapes the whole business. Manufacturers sell through dealers who hold stock close to buyers, advise on size, and arrange delivery. A dealer's customers are mainly households replacing old tanks, builders and plumbers fitting new houses, estate developers, schools and churches, and businesses such as car washes and water vendors.
Many dealers add related plastic products: buckets, drums, pipes and fittings, chairs and storage boxes. These sell faster than tanks and share the same delivery runs.
Choosing which manufacturer to stock
Customers often ask for tanks by brand, so stocking a known name helps. But the brand on the tank matters less to your margin than the terms behind it. Compare manufacturers on these points:
- Build quality: wall thickness, number of layers, UV stabilisation for tanks that sit in the sun, and lid and outlet fittings.
- Certification: SON runs a MANCAP certification scheme for locally made products; in 2021, for example, it told gas plants that locally made cylinders must carry a MANCAP number. Ask each tank manufacturer whether its tanks are MANCAP certified and for a copy of the certificate.
- Warranty: what it covers, who handles claims, and whether you or the factory replaces a cracked tank.
- Size range: whether the factory makes the sizes your area buys most, and how often popular sizes go out of stock.
Sizes and what buyers ask for
Manufacturers publish their own size lists, and these differ, so stock against what your area buys rather than the whole catalogue. As a rough guide to demand, households replacing a roof tank tend to ask for the smaller and middle sizes, builders fitting new homes buy several mid-size tanks at once, and estates, schools and businesses buy the largest sizes or several tanks linked together. Keep a sales book for three months and you will see which two or three sizes make most of your money; hold those in stock and order the rest when a customer pays a deposit.
Ask buyers where the tank will stand. A tank on a high stand or roof needs a stronger stand and careful lifting, and that conversation often leads to a second sale: stands, fittings, pipes and installation by a plumber you trust.

| Volume rebates | Discount or bonus after a monthly or quarterly target |
| Payment terms | Cash before loading, or credit after you build a record |
| Delivery to you | Whether the factory delivers to your yard and at what charge |
| Territory | Whether another dealer will be appointed nearby |
| Display and branding | Signage or display stock provided by the manufacturer |

Worked example: one month (example figures)
Example only. Prices are illustrative. Use the trade and retail prices you are actually quoted.
| Size | Sold | Buy price | Sell price | Margin |
|---|---|---|---|---|
| 1,000 litres | 10 | ₦90,000 | ₦105,000 | ₦150,000 |
| 2,000 litres | 6 | ₦160,000 | ₦185,000 | ₦150,000 |
| 5,000 litres | 2 | ₦380,000 | ₦430,000 | ₦100,000 |
| Total | 18 | ₦400,000 |
Against that ₦400,000: 12 delivery trips at ₦15,000 cost ₦180,000, of which customers paid back ₦120,000 at ₦10,000 a delivery, leaving ₦60,000. Rent for a yard is ₦80,000 and a helper is ₦100,000. That leaves ₦160,000 for the month. Holding one of each sale in stock would tie up ₦2,620,000 (10 × ₦90,000 + 6 × ₦160,000 + 2 × ₦380,000), so the return on stock is modest unless sales grow or the manufacturer gives credit.
Delivery: where profit is made or lost
- Tanks are light but take up a whole truck bed; plan routes so one trip serves several customers.
- Charge delivery as its own line on the invoice so customers see what they are paying for.
- Strap tanks properly; a tank that blows off a truck is lost margin and a road danger.
- Agree whether your price includes carrying the tank to the roof or stand. Installation is often a separate charge.
- Customers paying ₦10,000 or more by transfer bear a ₦50 stamp duty from January 2026, deducted from the sender, so it does not reduce what you receive.
Register the dealership with the CAC before approaching manufacturers; many prefer registered dealers, and the May 2025 schedule put business name registration at ₦20,000. For more on collecting payment, see POS terminal or bank transfer and how to get paid in Nigeria.
Where Pryme fits
Builders and estate managers often pay part now and part on delivery. A Pryme Business Account includes invoicing with delivery as its own line, bank-transfer checkout, and verifiable receipts through our partnership with VerifyDoc.ai.
Questions people ask
How do I become a water tank distributor in Nigeria?
Contact the manufacturer's sales office, ask for its dealer requirements, minimum order and trade price list, and register your business with the CAC. Get the terms in writing before paying for stock.
What is the profit on a water tank?
It depends on the trade price you are given and local competition. In our labelled example margins ranged from ₦15,000 on a 1,000-litre tank to ₦50,000 on a 5,000-litre tank, before delivery and rent.
Which water tank brand is best in Nigeria?
Compare wall thickness, layers, UV stabilisation, warranty and SON certification rather than the name alone. Ask each manufacturer for its MANCAP certificate and warranty terms.
How much does it cost to deliver a water tank?
It depends on distance, vehicle and how many tanks share a trip. Charge delivery as a separate line, and plan routes so one trip serves several buyers.
