Poor inventory management quietly erodes an SME's profitability. In this post, we cover the 5 most common mistakes we see — and how ISAR solves each one.

1. Tracking Stock in Spreadsheets

Spreadsheets work initially but break down at scale:

• Multiple employees editing the same file → version chaos
• Sales and stock integration is manual → high error risk
• No real-time visibility

ISAR solution: Sales, purchases, and transfers update stock instantly. Real-time inventory with per-warehouse tracking.

2. Inaccurate Cost Calculation

"I bought it for €10, sell it for €15, profit is €5" — this oversimplification misleads. Without factoring in shipping, storage, and returns, true margin is invisible.

ISAR solution: FIFO and average-cost methods for accurate profitability. Cost components per product.

3. Ignoring Minimum Stock Levels

"We're out of stock? Let's ship tomorrow." — That conversation costs you a customer.

ISAR solution: Minimum stock threshold per product. Automatic email + system alert when threshold is breached.

4. Failing to Manage Multi-Warehouse Operations

One warehouse in Amsterdam, another in Luxembourg, and a 3PL partner... Seeing all of them on one screen can feel impossible.

ISAR solution: Unlimited warehouse definitions, inter-warehouse transfers, WMS integration.

5. Infrequent or No Stock Counts

Annual stocktaking is no longer enough. Cycle counting catches errors early.

ISAR solution: Count module with instant recording, variance report, and automatic adjustment entry.
