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
Both sachet and bottled water plants must meet the same NAFDAC packaged water facility guideline: a fenced site with at least four rooms, a borehole of at least 150 feet, and treatment ending in UV and a 0.5 micron filter. The difference is in machines and selling: in our labelled examples a sachet plant costs about ₦20.1 million and earns ₦70 a bag, while a bottled plant costs about ₦34 million and earns ₦290 a pack of 12. Sachet suits high-volume local markets; bottled suits areas with offices, events and shops that pay more per litre.
What both factories have in common
NAFDAC's guideline for registering a packaged water facility (FSAN-GDL-002-01, effective 1 June 2018) applies to sachet and bottled water alike. Whatever you package, you build the same foundations, and that part of the budget does not shrink because you choose sachets.
- A fenced facility with at least four rooms, kept separate from living areas.
- A borehole of at least 150 feet, no dug wells, sited at least 30 metres from any septic tank.
- Treatment by chlorination (2 to 4 ppm), reverse osmosis or ozone, with UV before filling and a final 0.5 micron filter.
- A certificate of analysis from an analyst registered with the Institute of Public Analysts of Nigeria.
- Medical tests for food handlers (sputum, hepatitis B, Widal, stool and urine) and a technical officer with at least an OND.
- Quarterly fumigation certificates and CAC registration documents.
NAFDAC's 2019 tariff, the most recent full schedule we found, listed laboratory analysis at ₦40,000 for bottled water and ₦20,000 for sachet water. In January 2024 NAFDAC said it had cut renewal processing fees for local manufacturers to ₦44,200. Treat both as dated and confirm the current invoice with NAFDAC when you apply.
Where the two plants differ
| Sachet water | Bottled water | |
|---|---|---|
| Packaging machine | Form-fill-seal machine using printed sachet film | Bottle blower (or bought-in bottles), filler, capper, labeller, shrink-wrapper |
| Packaging inputs | Sachet film and bags | Preforms, caps, labels, shrink film |
| Example set-up cost (our guides) | about ₦20.1 million | about ₦34 million |
| Example cost per unit | ₦180 per bag | ₦810 per pack of 12 |
| Example price to distributor | ₦250 per bag | ₦1,100 per pack |
| Example margin per unit | ₦70 per bag | ₦290 per pack |
| Typical buyers | Distributors, kiosks, households, markets, motor parks | Supermarkets, offices, events, hotels, restaurants |
| Main risk | Price wars between nearby plants | Slower sales and higher packaging cost per litre |
The example figures come from our detailed guides to a sachet water factory and a bottled water business, where every line is labelled and explained. They are examples, not market prices.
Comparing margins fairly
Example only. At 1,000 units a day, the sachet plant earns a gross margin of ₦70,000 a day and the bottled plant ₦290,000. On those numbers, the sachet plant's set-up cost equals about 287 days of gross margin (₦20.1 million ÷ ₦70,000) and the bottled plant's about 117 days (₦34 million ÷ ₦290,000), before rent, salaries and maintenance.
That looks like a clear win for bottled water, but the comparison hides the hard part: selling 1,000 packs of bottled water a day is far harder than selling 1,000 bags of sachets in most neighbourhoods. A bottled plant that sells 300 packs a day earns ₦87,000, only a little more than the sachet plant at full volume, on much more capital. Margin as a share of cost is close in both examples (about 39% for sachets and 36% for bottles), so the decision turns on how many units you can sell, not on which product is "more profitable".
Running costs that behave differently
The set-up budget gets the attention, but running costs decide whether a plant survives its first year. Some costs are shared and some are not.
- Packaging
- Sachet film is cheap per litre. Preforms, caps, labels and shrink film make packaging the largest single cost line in the bottled example.
- Power
- Both plants run pumps and treatment. Bottled lines add bottle blowing and capping, so power per litre is higher.
- Staff
- A sachet line needs packers and loaders; a bottled line needs operators who can set up the blower and filler, and more careful quality checks.
- Compliance
- Fumigation, staff medicals, laboratory analysis and registration renewals apply to both, product by product.
- Transport
- Sachet bags sell close to the plant in large numbers; bottled packs travel further to shops and offices, so delivery costs more per sale.
A useful test is to work out how many units you must sell each day just to cover monthly overheads. Divide the month's rent, salaries, maintenance and renewals by the margin per unit and by working days. If that number is close to what you can realistically sell, the plant is fragile whichever product you choose.
Decision guide
- Count your buyers first. List the distributors, shops and offices within delivery range and ask what they buy now and from whom.
- Match capital to risk. If your budget barely covers a bottled line, a sachet plant leaves room for working capital and a delivery vehicle.
- Check your competitors. Many areas already have several sachet plants; a bottled brand may face less direct competition but needs shelf space.
- Price your power. Bottle blowing and filling use more energy per litre; work out power cost per unit, not per month.
- Plan to add the other later. The facility, borehole and treatment are shared, so many owners start with sachets and add a bottling line when distributors ask for it.
Distribution is its own business; see pure water distribution for the other side of the trade.
Where Pryme fits
Distributors often pay daily by transfer. A Pryme Business Account can give each distributor their own virtual account so payments match the right customer, and invoicing covers supermarket and hotel orders.
Questions people ask
Which is more profitable, pure water or bottled water?
Neither by default. In our labelled examples the margin as a share of cost was similar (about 39% sachet, 36% bottled). Bottled earns more per unit, but you must sell enough packs; volume decides the answer.
How much does it cost to start a pure water factory in Nigeria?
Our labelled sachet example came to about ₦20.1 million including borehole, treatment, machines and working capital. Your figure depends on land, building and machine choice.
Do sachet and bottled water need the same NAFDAC requirements?
Yes. NAFDAC's packaged water facility guideline applies to both: fenced site, at least four rooms, 150-foot borehole, UV and 0.5 micron filtration, analyst certificate and staff medicals. Laboratory analysis fees differed in the 2019 tariff.
Can I produce sachet and bottled water in the same factory?
Many owners do, because the facility, borehole and treatment are shared. Each product still needs its own registration and analysis; confirm the details with NAFDAC.
