How to Control Inventory Using ERP Software
Published 7 November 2026 · Cirumtech ERP team
For most trading, distribution and manufacturing businesses, inventory is the largest asset on the balance sheet after receivables. Poor stock control shows up as cash tied up in slow-moving items, lost sales from stock-outs, and unexplained differences at every stock count.
ERP software gives you the tools to control inventory, but only if they are set up and used properly. Here are seven practical techniques.
1. Build a clean item master
Everything starts with the item master. Each product should exist once, with a clear code, description, category, unit of measure and, where relevant, variants such as size, color or style. Duplicate items ("Bolt 10mm" and "10mm Bolt") are the most common cause of wrong stock figures.
- Use a consistent naming and coding convention.
- Group items into categories and sub-categories for reporting.
- Mark items that need serial numbers or batch tracking.
- Deactivate obsolete items instead of reusing their codes.
2. Organize stock by warehouse and location
Set up each physical place where stock is kept (warehouses, shops, factory stores, even bins or racks) as a location in the ERP. Every receipt, transfer and issue then names a location, so you always know not only how much you have, but where it is.
3. Set reorder levels and maximum levels
For each important item, define a minimum (reorder) level and a maximum level. A simple starting point:
Reorder level = average daily usage × supplier lead time in days + safety stock
For example, if you sell 40 units a day, the supplier takes 10 days to deliver and you keep 100 units of safety stock, the reorder level is 40 × 10 + 100 = 500 units. The ERP's reorder report then tells purchasing exactly what to buy and when. Review the levels each season if demand changes.
4. Track batches and serial numbers where they matter
Batch tracking is essential for products with expiry dates, dye lots or quality grades. Serial numbers are essential for high-value items and anything under warranty. With tracking switched on, you can follow every unit from the vendor to the customer.
5. Make every stock movement a document
Stock should only change through a document in the system: goods receipt, transfer, issue to production, delivery, return or adjustment. Avoid informal movements ("we'll enter it later"). Use approvals for adjustments and write-offs so that no one can quietly change stock figures.
6. Count regularly with cycle counts
An annual stock-take finds problems too late. Instead, count a small group of items every week, with fast-moving and high-value items counted most often. Enter counts in the ERP, investigate differences immediately and post approved adjustments. Over time, the reasons for differences become clear and can be fixed.
7. Use inventory reports every week
- Stock on hand by location: what you have and where.
- Reorder report: items below their reorder level.
- Slow-moving and dead stock: items with no movement in 90 or 180 days.
- Stock valuation: the value of inventory for the balance sheet.
- Stock movement history: every transaction for an item, to investigate differences.
Connect inventory to purchasing, sales and accounts
Inventory control works best when it is not a separate system. In an integrated ERP, purchase orders create expected receipts, sales orders reserve stock, deliveries reduce it, and every movement posts its value to the general ledger. Stock in the warehouse and stock in the accounts then always agree.
