The cost of stock-out and the cost of over-stock

Every distribution business in Ethiopia knows the pain on both sides. Stock-out: lost sales, customer churn, scrambled emergency purchases at premium prices, supplier-relationship strain. Over-stock: cash tied up that could fund growth, warehouse space consumed, write-downs on aged or expired stock, FX losses on inventory bought at unfavorable rates.

Good inventory software shifts both failure modes to "rare". Automated reorder points are the mechanism.

The reorder-point formula

The basic formula:

`Reorder point = (Average daily consumption × Supplier lead time in days) + Safety stock`

Where:

• Average daily consumption is computed from recent history (typically the last 30, 60 or 90 days, depending on volatility).
• Supplier lead time is the average days from PO to received-and-cleared-into-stock.
• Safety stock is a buffer to absorb consumption spikes and supplier delays.

When current stock dips below the reorder point, a purchase order is raised. The order quantity is typically set to bring stock up to a max level: max stock minus current stock.

NYLOS computes all of this automatically per item per warehouse, using rolling historical data.

Why "automatic" is harder than it sounds

Three reasons a naive reorder-point formula fails in Ethiopian operations:

1. Lead times vary. Local supplier vs imported supplier differ by weeks. A static lead time misses this.
2. Consumption is seasonal. School-year peaks for stationery; holiday peaks for F&B; rainy-season peaks for construction. A static daily average misses seasonality.
3. Safety stock is too often a guess. Properly computed safety stock factors in consumption volatility and lead-time volatility statistically — but most ops teams use round numbers.

NYLOS supports both basic and dynamic reorder configurations. The basic mode uses static values that work for stable inventory. The dynamic mode adjusts the reorder point based on recent consumption trends and observed lead-time variance.

Configuring NYLOS reorder

Per item, per warehouse, NYLOS lets you configure:

• Reorder method: static (fixed reorder point) or dynamic (rolling computed).
• Min stock: the reorder trigger.
• Max stock: the order-up-to ceiling.
• Lead-time days: the typical supplier lead time.
• Safety stock days: buffer expressed in days of consumption.
• Preferred supplier: who to order from automatically.
• Approval workflow: who needs to approve the auto-generated PO before it's sent.

The PO workflow

When stock dips below the reorder point:

1. NYLOS auto-generates a purchase requisition for the order quantity.
2. The procurement officer is notified.
3. The PO is reviewed, edited if needed (e.g. switching to an alternate supplier), and approved.
4. The PO is sent to the supplier — by email or printed for delivery.
5. Goods receipt closes the loop with three-way matching against the PO and supplier invoice.

This workflow keeps a human in the loop — the auto-generated PO is a proposal, not a commitment.

Multi-warehouse complication

In multi-warehouse operations, the calculation gets harder. Should reorder be triggered at the branch level or the central level? Should branch stock-outs be served from another branch's surplus, or from the central depot?

NYLOS supports both patterns:

• Branch reorder: each branch maintains its own reorder points, and POs are raised per-branch directly.
• Central reorder: the central planner sees consolidated demand, raises consolidated POs, and allocates received stock to branches.

Most NYLOS customers run hybrid: high-volume SKUs are central-reordered; long-tail SKUs are branch-reordered.

Imports and FX

Imported items add another wrinkle. Lead times stretch to weeks or months. FX volatility means the cost of the next PO is uncertain at the time of trigger. Customs clearance adds variability.

NYLOS handles imports with extended lead times in the same framework. Multi-currency POs are recorded at expected rates; landed cost is captured at receipt; cost variances are surfaced for review.

For high-FX-exposure imports, NYLOS customers commonly use larger safety stock buffers and accept the higher inventory holding cost in exchange for lower stock-out risk.

Common pitfalls

Five patterns to avoid:

1. Reorder points set once and never reviewed — consumption shifts, lead times change, but the static values stay.
2. Same reorder point across branches — branch consumption patterns differ.
3. Auto-PO without approval — purchase commitments going out without human review.
4. Min stock set lower than safety stock — guaranteed stock-out before reorder triggers.
5. Reordering one item at a time — every PO has a fixed cost (admin, freight); consolidate where supplier and timing permit.

How NYLOS handles automated reorder

NYLOS computes reorder triggers per item per warehouse on a continuous basis, raises auto-generated POs with full approval workflow, supports branch and central reorder patterns, factors in supplier lead times and import cycles, and preserves the full audit trail of why each PO was raised — useful when reviewing procurement effectiveness over time.
