Managing inventory is one of the most critical — and most mismanaged — aspects of running a small or medium-sized business in Nigeria.
Whether you sell electronics in Onitsha, run a supermarket in Abuja, or operate a fashion store on Lagos Island, these mistakes could be quietly eating into your margins.
1. Not Tracking Stock in Real Time
Many SMEs still rely on notebooks or Excel spreadsheets updated once a week. By the time you realise you've run out of a product, you've already lost sales.
Fix: Use a point-of-sale system like Inventino that automatically deducts stock with every sale, so your count is always current.
2. Ignoring Reorder Points
Waiting until a shelf is empty before ordering is a reactive — and costly — approach. It results in stockouts and dissatisfied customers.
Fix: Set a minimum reorder quantity for every product. When stock hits that level, your system should alert you — or even trigger a purchase order automatically.
3. Lumping All Products Under One Category
When every product is just "goods purchased," your reports are useless. You can't see which categories are driving profit.
Fix: Structure your products into clear categories (Electronics, Groceries, Clothing, etc.) so you can analyse performance by category.
4. Ignoring Expiry Dates
This is especially critical for food, cosmetics, and pharmaceuticals. Selling expired goods risks your customers' health and your business licence.
Fix: Track expiry dates for every perishable SKU. Set alerts for items approaching expiry so you can run promotions before they're wasted.
5. Over-Ordering "Safe Stock"
Trying to avoid stockouts by ordering excess inventory ties up capital and creates storage costs — especially during Nigeria's unstable FX environment when import purchases are involved.
Fix: Use historical sales data to forecast demand accurately. Inventino's reports show you average daily sales per product so you can order smarter.
6. Skipping Regular Stock Counts
Some businesses only do a physical stock count annually. Discrepancies caused by theft, breakage, or recording errors go undetected for months.
Fix: Schedule monthly mini stock counts — or spot-check your top 20 products weekly. Reconcile with your system records.
7. Not Tracking Units of Measure
Buying in cartons but selling in units without proper conversion tracking leads to inaccurate stock levels and incorrect COGS calculations.
Fix: Set up unit-of-measure conversions in your inventory system (e.g., 1 carton = 24 pieces).
8. Forgetting to Account for Returns
Returned items often get placed back on shelves without being re-entered into the system, causing a mismatch between physical and system stock.
Fix: Always process returns through your POS. Inventino's return flow automatically restores stock to the correct quantity.
9. Ignoring Supplier Lead Times
If your supplier takes 2 weeks to deliver but you only reorder when you're completely out of stock, you'll have 2 weeks of zero sales on that product.
Fix: Factor lead time into your reorder point calculation: Reorder Point = (Average Daily Sales × Lead Time) + Safety Stock.
10. Not Locking Down Access
Allowing all staff to adjust stock quantities or delete transactions is an open invitation to fraud and errors.
Fix: Use role-based access control. Cashiers should only record sales; only managers should be able to approve adjustments.
