Stock Management for Growing FMCG Brands in Nigeria

Growing FMCG brands in Nigeria regularly encounter a specific pattern: the business is expanding into more retail accounts, production is increasing to meet demand, and then a stockout event occurs that cascades into a supplier reliability problem with one or more key retail accounts. The root cause is almost always an inventory system that has not kept pace with the complexity of the growing distribution network.

When a brand is supplying five stores, inventory management is manageable through intuition and a simple spreadsheet. When the same brand is supplying 50 stores with different delivery frequencies, different velocity profiles, and different minimum order quantities, the intuitive approach breaks down. Stockouts become more frequent, overstock builds in some accounts while others run dry, and the field team spends more time managing crises than building relationships.

A reorder point (ROP) is the stock level at which a replenishment order should be placed to ensure that stock arrives before the current inventory runs out. Calculating it correctly prevents both stockouts and the excess inventory that leads to expiry problems.

The formula is straightforward: ROP equals average daily sales multiplied by lead time in days, plus safety stock. If a store sells 20 units per day and your lead time from order placement to delivery is 3 days, your ROP is 60 units plus safety stock. Safety stock is typically calculated as average daily sales multiplied by the maximum lead time variation: if your lead time varies between 3 and 5 days, safety stock is 20 units multiplied by 2, or 40 units. The ROP in this example is 100 units.

Applying this calculation across every store and SKU in your network gives you a data-driven replenishment system rather than a reactive one. When stock at any location hits the reorder point, an order is placed. Without this trigger, orders are placed when someone notices the shelf is empty, which is always too late.

How your warehouse is organised determines how efficiently product moves from production to retail, and whether FIFO rotation is actually applied in practice. A warehouse where products are stored with the newest production runs accessible at the front and older stock buried at the back is a warehouse that will generate expiry problems regardless of how good the policy documentation says the rotation should be.

Organising the warehouse for FIFO compliance requires physical bin and shelf organisation that makes older stock easier to pick than newer stock. This often means a flow-through racking system, or at minimum a strict labelling and zone system that designates older stock in a designated pick-first area. The investment in proper warehouse organisation pays back quickly in reduced expiry write-offs and cleaner quality management.

The inventory challenge in modern trade distribution is that your effective inventory is not just what is in your warehouse. It is distributed across every retail location where your product sits. The stock in your warehouse, the stock on each retail shelf, and the stock in each store's back area all constitute your active inventory from a brand management perspective.

Managing this distributed inventory requires visibility into each location. Field visits that include a stock count at the store level, reporting back to your central inventory record, create the visibility needed to make rational replenishment decisions. Without this visibility, you are ordering based on what left your warehouse, not on what is actually available at each retail point.

Brands working with DALA as a distribution partner receive weekly store-level stock reports as part of the partnership, which provides the distributed inventory visibility that is otherwise expensive to generate independently.

Production constraints, planned or unplanned, are a regular feature of FMCG operations in Nigeria. Power interruptions, raw material delivery delays, and equipment maintenance requirements can all interrupt production runs at short notice. A brand with no buffer stock strategy when production stops has no ability to supply its retail accounts during the interruption.

Building a buffer stock strategy means maintaining a defined minimum inventory level, typically four to six weeks of average retail demand, that serves as the cushion between production and retail. When production is interrupted, the buffer absorbs the disruption for the period needed to resolve the production issue. When production resumes, the priority is restoring the buffer before accepting new retail orders beyond normal replenishment.

For brands with limited storage capacity, maintaining a multi-week buffer is not always feasible. In these cases, a documented production contingency plan, identifying alternative production capacity or a co-manufacturer who can step in during a disruption, serves a similar function. The plan needs to exist before the disruption occurs, not be created in the middle of one.
