This morning, business owners and managers from across Ruiru joined us at Ndanga International Hotel for our Inventory Mastery breakfast forum. Over coffee and a full room, we worked through the practical side of inventory management — not the textbook version, but the parts that quietly decide whether a business keeps its cash working or watches it sit frozen on the shelves. Whether you were there or are reading this for the first time, this is the full session in one place, written so you can come back to it whenever you need a refresher.
1. Stock Is Money Waiting
Start with a shift in how you see your shelves. Every item sitting there is cash you have already spent that has not yet turned back into a sale. A store full of stock is not the same as a healthy business — it can just as easily be a business with all its money locked up where it cannot be used. Managing inventory well is not about holding more; it is about holding the right things, in the right amount, at the right time, so your cash spends as little time as possible frozen on a shelf.
2. Both Ends of the Problem Cost You
There are two ways to get inventory wrong, and both are expensive. Carry too much and you tie up cash, fill your store with items that may expire or go out of style, and pay to store and insure stock that is not earning. Carry too little and you lose the sale the moment a customer asks for something you do not have — and often you lose the customer too, because they simply buy it from a competitor who had it. These look like opposite problems, but they share one root cause: not knowing your true stock position in real time. Fix the visibility and both ends start to correct themselves.
3. The 80/20 Rule
One of the most useful ideas in the room was also the simplest. In most businesses, roughly 20% of your products bring in about 80% of your money. The remaining 80% of your product lines barely move the needle — and a portion of them are dead stock, quietly costing you in storage and tied-up cash every single month. The moment you know which products sit in your top 20% and which sit at the bottom, your buying decisions change: you protect and prioritise the few that carry the business, and you stop pouring money into the many that do not.
4. Find Your Dead Stock: ABC and the Growth-Share Matrix
To turn the 80/20 idea into action, we used two simple tools. ABC analysis ranks your stock by value:
- A items — the money-makers you watch closely and never let run out
- B items — steady performers that need only occasional attention
- C items — the slow or dead stock where cash quietly disappears
The Growth-Share Matrix adds a second question — is demand for this item growing or fading? — sorting stock into Stars to grow, Cash Cows to keep steady, Question Marks to test carefully, and Dogs to clear out. The message underneath both tools was the same: if a product has not moved in months, it is not "just sitting there." It is cash you cannot use anywhere else in your business.
5. Watch for the Warning Signs
Some problems announce themselves if you know what to look for. The clearest is a sale going through against zero or negative stock — a report showing minus three of something you supposedly sold. That is not a system glitch; it is proof that the paper trail broke somewhere upstream. An item was sold before it was ever properly recorded as received, or a stock take was skipped, and now every number that depends on it is unreliable. The fix is discipline in the documents most businesses treat as optional:
- Purchase orders when you order
- Goods received notes when stock arrives
- Delivery notes when it leaves
- Regular stock takes to confirm the books match the shelf
That paper trail is what keeps every other number trustworthy.
6. Don't Over-Diversify
It is tempting to stock a bit of everything, because more variety feels like more opportunity. In practice, over-diversification usually just freezes your cash across too many slow movers, leaving too little for the products that actually sell. The answer is not necessarily a narrower range — it is buying smarter. Just-in-Time thinking means ordering smaller amounts more often, so stock arrives close to when you need it rather than sitting in your store for months. Your cash stays free and working, your stock stays fresh, and you can still carry variety without paying to warehouse it. It works best when you have reliable suppliers and a real sense of your demand — which is exactly what good records give you.
7. Stock and Cash Flow Are the Same Conversation
Perhaps the biggest shift for the room was seeing that inventory decisions are cash-flow decisions. When you reorder, how much you buy, the credit terms you give customers versus the terms your suppliers give you, whether you stock up ahead of a slow season — every one of these decides when money comes into your business and when it goes out. A reorder level set without a thought for cash timing can strain you at exactly the wrong moment. Set them together, and inventory stops being a cost you manage and starts being a lever you use.
8. Where TallyPrime Fits
Everything above is a discipline first, and no software will fix a broken process. But once the habits are in place, the right system makes them far easier to sustain — and that is where TallyPrime comes in:
- It links your paperwork automatically, so the order, goods received note, sale, and delivery note all connect without extra effort
- It shows an item's buying price at the point of sale, so pricing is based on real margin rather than a guess
- It ranks your fast and slow movers for you, turning ABC analysis into a report instead of a manual exercise
- It keeps your stock valuation consistent instead of reconstructed at year-end
Think of it as a multiplier on good habits, not a substitute for them.
The Bottom Line
Thank you to everyone who joined us this morning — the questions and real stories in the room are what made the session. If there is one thing to carry away, it is this: good inventory management is not a software feature. It is a habit of knowing what you have, tracking what moves, and watching where your cash gets stuck. Get that foundation right and everything else, including the tools, works better. If you would like a one-on-one look at how any of this applies to your own business, we are only a call away — reach us on +254 116 246 074 or book a free demo through our website.
