Stock management for shops in Cameroon: the method to stop stock-outs and theft

A customer walks into your shop in Mokolo, asks for your best-selling item, and leaves empty-handed: it's out of stock. Meanwhile, at the back of the shop, boxes of a product that no longer sells have been gathering dust for eight months. And at the last stock count, the equivalent of 400,000 FCFA of goods was missing, with nobody able to explain why.

Stock-outs, overstock, unexplained discrepancies: these are the three diseases of a shop's stock. They have the same cause. You don't know, at any given moment, what you actually have on the shelves, what's selling, and what's disappearing.

For a retailer, stock is often the biggest item of tied-up money, ahead of cash. Poorly managed, it costs you three times: in lost sales (stock-outs), in idle money (overstock), and in stolen or lost goods (shrinkage).

This guide gives you a complete, practical method adapted to Cameroonian shops: the basic rules, how to calculate your reorder point, the ABC method to know where to focus your efforts, the controls that make theft drop, and the role of stock management software.

The 3 diseases of stock (and what they cost you)

1. Stock-outs: the sale you'll never see

A stock-out doesn't show up in any accounts: the sale simply didn't happen. The customer went next door, and next time, they may go straight there. Stock-outs almost always affect the best-selling products, precisely because they go quickly and aren't watched closely enough.

2. Overstock: money sleeping on your shelves

Every extra box is tied-up money you can't use to buy what sells. Overstock also takes up space, deteriorates (humidity, heat, dust), goes out of fashion (clothing, phones) or expires (food, cosmetics). In the end, it gets sold off cheaply or thrown away.

3. Shrinkage: stock that disappears

Shrinkage is the gap between theoretical stock (what you should have) and actual stock (what's physically there). It has four sources:

• External theft: customers hiding items.
• Internal theft: employees taking goods out, selling without recording, or "forgetting" to charge friends and family.
• Supplier errors: incomplete deliveries accepted without checking.
• Administrative errors: sales entered incorrectly, broken or expired items never recorded, counting errors.

An important point: without precise tracking, it's impossible to distinguish between these four causes. As long as you don't know where the gap comes from, you can't fix it.

Rule 1: every stock movement must leave a trace

All stock management rests on a single discipline: no item comes in or goes out without being recorded. The movements to track are:

• Stock in: supplier receipt (with quantity check), customer return.
• Stock out: sale, supplier return, breakage, expiry, internal use, donation or sample.
• Transfers: from a depot to a shop, from one shop to another.
• Adjustments: corrections after a stock count, always justified and approved by the manager.

If even one of these categories escapes recording, your theoretical stock becomes wrong, and so do all your calculations. That's why notebooks and Excel reach their limits so quickly: they depend on everyone's goodwill, on every transaction. We've put a figure on what this way of working costs in our article Managing your business with Excel: why it always ends up costing you.

Rule 2: focus your efforts with the ABC method

You may have 500 or 1,000 items. You can't watch them all with the same attention. The ABC method tells you where to look.

It's based on the Pareto principle: a small number of items, around 20% of your references, generally accounts for most of the value, often between 60 and 80% of revenue (definition detailed by the Office québécois de la langue française). You therefore sort your items into three groups:

How to do your classification

1. List your items with their revenue over the last 3 or 6 months.
2. Sort them from best-selling to worst-selling (by value, not quantity).
3. Add up the percentages: the items making up the first 80% are your A items, the next ones up to 95% are your B items, and the rest are your C items.

In a hardware store, the A items might be cement, roofing sheets and reinforcing bars. In a cosmetics shop, a handful of creams and hair extensions. In a general food store, rice, oil, sugar and drinks.

What it changes: your A items must never be out of stock, and they're the ones you count most often, because theft and errors affecting them cost the most. Stock management software does this classification automatically based on your sales.

Rule 3: calculate your reorder point (no more stock-outs)

The reorder point is the stock level at which you need to reorder so you don't run out before the next delivery. It's simple to calculate:

Reorder point = (average daily sales × delivery time in days) + safety stock

A concrete example

You sell an average of 8 cases of oil a day. Your supplier delivers in 5 days. As their lead times are sometimes irregular (roads, stock-outs on their side), you keep 3 days of safety stock.

• Stock used during delivery: 8 × 5 = 40 cases
• Safety stock: 8 × 3 = 24 cases
• Reorder point: 64 cases

As soon as your stock falls to 64 cases, you reorder. Not before (overstock), not after (stock-out).

Adapting safety stock to the Cameroonian context

Safety stock must reflect your real risks: the rainy season slowing deliveries, frequent stock-outs at the wholesaler, predictable increases in demand (back to school, end-of-year holidays, Ramadan, Tabaski). For your A items, be more generous. For your C items, stay at the minimum.

What software does: it continuously calculates your average sales, compares stock with the reorder point set for each item, and sends you a restocking alert. Some software even directly suggests a pre-filled supplier order list.

Rule 4: check deliveries (the forgotten theft)

Part of shrinkage comes in through the back door, with the supplier. A delivery of 50 cases invoiced, 47 actually dropped off: if nobody counts, the difference is lost.

Good practice:

1. Compare the delivery with the purchase order, item by item, before signing.
2. Count physically in the presence of the delivery person.
3. Note any discrepancies and damaged items on the delivery note, signed by both parties.
4. Record the stock receipt immediately, based on the quantities actually received.

With software, goods are received against the recorded order: the storekeeper enters the quantities received, and discrepancies appear automatically. The claim to the supplier goes out with proof.

Rule 5: the controls that make theft drop

Internal theft is a sensitive subject, but one you can't avoid. It's not about suspecting everyone: it's about setting up a system where stealing becomes difficult and visible. Most honest people stay honest, and the others think twice.

The 7 most effective controls

1. No sale without a receipt or invoice. Every sale goes through the till or the software, which automatically removes the item from stock. An "off-the-books" sale creates a discrepancy that will eventually show up.
2. Personal logins. Each salesperson has their own account. Sales, discounts and cancellations are linked to a person. No more "it wasn't me".
3. Cancellations and discounts under control. Above a certain amount, a sale cancellation or a discount must be approved by the manager. It's one of the most common fraud techniques: record a sale, collect the money, then cancel it.
4. Daily till closing. Every evening, the money counted (cash + Mobile Money) is compared with the sales recorded. A discrepancy is dealt with the same day, not at the end of the month.
5. Justified non-sale withdrawals. Breakage, expiry, internal use: each withdrawal is recorded with a reason and approved.
6. Surprise cycle counts. Rather than one big annual stock count, count a small selection of items every week, prioritising A items, at an unannounced time. A discrepancy on a specific item, for a specific week, is much easier to trace than an overall discrepancy over a year.
7. Storage of sensitive items. Small, valuable items (phones, accessories, perfumes, branded cosmetics) are kept behind the counter or in a locked display case.

Cameras have a real deterrent role, but they don't replace these controls: a camera shows a gesture, not a stock discrepancy.

💡 The telltale sign: when you install stock management software with personal logins and one of your employees strongly resists it, take the time to understand why. Traceability rarely bothers those with nothing to hide.

Rule 6: rotate your stock

First in, first out

For products that expire or deteriorate (food, drinks, cosmetics, medicines, batteries), apply the FIFO rule (first in, first out), or better still, FEFO (first expired, first out): the items with the nearest expiry date go first. When putting away a delivery, the new items go at the back and the old ones stay at the front.

Software can manage batches and expiry dates, and alert you to items approaching their date, early enough to organise a promotion rather than a loss.

The indicators to track

• Stock turnover: how many times your stock is renewed over a period. The higher it is, the less your money sits idle.
• Stock coverage: how many days of sales your current stock represents. 15 days of coverage on an A item is comfortable. 200 days on a C item is tied-up money.
• Dead stock: items with no sales at all for 60 or 90 days. These are your candidates for promotions, bundles, supplier returns or delisting.
• Shrinkage rate: the gap between theoretical and actual stock, by value, relative to your purchases. Track it after each stock count: it's the barometer of your controls.

Why stock management software changes everything

All the rules above could theoretically be applied with a notebook and a lot of discipline. In practice, in a shop making dozens or hundreds of sales a day, it's impossible to keep up. Software applies them automatically, on every transaction:

Action plan: get your stock back on track in 30 days

Week 1: the starting point. Do a complete physical stock count, with the shop closed or outside opening hours. This is your opening stock, the only reliable basis. Use the opportunity to clean up your item list (duplicates, inconsistent names, items that no longer exist).

Week 2: the tool and the rules. Install your software, import the counted stock, create personal logins. Set the rules: no sale without recording, cancellations approved by the manager, deliveries checked.

Week 3: priorities. Draw up your ABC classification based on recent sales. Set a reorder point for each of your A items, then for the B items.

Week 4: the routine. Start weekly cycle counts on A items and daily till closing. List your dead stock and decide on an action for each item (promotion, bundle, return, discontinuation).

Then: the ritual. Every Monday, 20 minutes: restocking alerts, results of the cycle count, the week's till discrepancies. That's it. Your stock is under control.

FAQ

How often should you do a stock count? A full stock count at least once a year (it's also an accounting requirement for the year-end close), supplemented by weekly cycle counts on A items. Cycle counts let you spot discrepancies quickly, while they can still be explained.

What shrinkage rate is "normal" for a shop? It depends heavily on the sector and the organisation. The right reflex isn't to compare yourself with an average, but to measure your own rate after each stock count, then bring it down. A rate that doesn't fall after controls are put in place signals a specific problem to investigate.

Will my employees resent the introduction of controls? Present them as protection for everyone: with personal logins and till closings, an honest employee can no longer be wrongly suspected. Explain the rules, train the team, and apply them to everyone, including yourself.

Can you manage several shops with a single piece of software? Yes: stock per shop or per depot, tracked transfers between sites, and a consolidated dashboard for the manager. It's actually one of the cases where software adds the most value.

What if the internet connection drops? Choose software that works offline: the shop keeps selling and recording stock withdrawals, then everything syncs when the connection returns. Software that freezes at every outage pushes your salespeople back to the notebook, and your stock becomes wrong again.

Conclusion: controlled stock means money recovered

Stock-outs, overstock and theft aren't an inevitable part of retail in Cameroon. They're the symptoms of stock you can't see. Six rules are enough to take back control: track every movement, classify your items, calculate your reorder points, check deliveries, make theft difficult and visible, and rotate your stock.

Stock management software makes these rules automatic, even in a very busy shop. At Alivaon, in Douala, we design stock and inventory management software adapted to Cameroonian shops and businesses: real-time stock, restocking alerts, barcodes, multiple shops, batches and expiry dates, stock counts on your phone and offline operation. It integrates with your till/POS, your DGI-compliant invoicing and your sales management.
