A warehouse is not a storage room but a ledger kept in items instead of riyals. It has inputs, outputs, documents and balances, and it is reconciled exactly as accounts are.
1 The core warehouse movements
| Movement | Document | Effect on the balance |
|---|---|---|
| Receipt from a supplier | Goods receipt note linked to a purchase order | Increase |
| Issue for a sale | Picking note / delivery note | Decrease |
| Issue for internal use | An approved requisition from the department | Decrease |
| Return from a customer | Return note and credit note | Increase |
| Return to a supplier | Supplier return note | Decrease |
| Transfer between warehouses | A two-sided transfer note | Decrease here, increase there |
| Stocktake adjustment | Approved count minutes | Increase or decrease |
| Write-off | Disposal minutes by a committee | Decrease |
The one-sided transfer
Goods left branch one and the issue was recorded; nobody recorded the receipt at branch two. The result: a shortage here and a surplus there, and a group total that hides two errors. A transfer is not closed until receipt is confirmed, and until then it sits in “goods in transit”.
2 The item master
- Item code: a fixed reference that never changes and is never reused.
- A standard description in an agreed format that stops one item being created twice.
- Unit of measure and the conversion factor between carton and piece.
- Default location inside the warehouse.
- Levels: minimum, reorder point and maximum.
- Control attributes: is it tracked by batch? by serial number? by expiry date?
- Approved supplier and the usual lead time.
The duplicated item: a silent enemy
“3 inch nail”, “Nails 3” and “3in screw” — three records for one item. One of them runs out while another sits on the shelf, an item already in stock gets bought again, and every turnover report becomes meaningless. A single naming policy and the right to create items restricted to one person prevents this at the root.
3 Location coding and shelf layout
Zone
A · B · C
Aisle
01 · 02 · 03
Rack
A · B · C
Level
1 · 2 · 3
A location such as “B-03-A-2” gets a new employee to the item without asking anyone
- Fast-moving items go near the despatch door to cut walking.
- Heavy low, light high — safety before tidiness.
- Oldest to the front so it is issued first, especially for items with an expiry date.
- A quarantine area for goods pending inspection and for rejected goods, kept apart from sellable stock.
- Clean, well-lit aisles — most count differences come from goods sitting in the wrong place.
4 Controls that are not relaxed
A technician needs a part urgently and the storekeeper has gone home. He takes it and says, “I will record it tomorrow.” That happens eight times a month across five employees:
| Unrecorded movements per month | 40 |
| Average value per part | 350 |
| Expected annual count difference | 168,000 |
And nobody stole anything. The whole difference comes from real movements with no document. The remedy is not harsher penalties but making issue possible around the clock with a simple document approved afterwards — because a procedure that blocks the work will always be bypassed.
| Control | Why |
|---|---|
| No issue without an approved document | Without it the book balance means nothing |
| Restricted access to the warehouse | Custody cannot be controlled in an open space |
| Whoever issues does not count | So they cannot cover their own shortage |
| Record the movement as it happens | Deferral is the origin of most differences |
| Periodic reconciliation of system to reality | Catch the error while it is small |
Lesson summary
- The balance is the result of documented movements, not a number typed or corrected by hand.
- A transfer between warehouses is not closed until receipt is confirmed.
- The item master settles the unit, the location, the levels and the tracking method.
- A duplicated item corrupts turnover and causes repurchase of what is already there.
- Location coding makes the warehouse independent of individual memory.
- Most count differences come from real movements without a document, not from theft.
5 Test your understanding
Three quick questions
Pick the answer you believe is correct and you will see the result immediately.
1. An issue was recorded at branch one and no receipt was recorded at branch two. The result:
A transfer is a two-sided movement, and it is not closed until the receiving side confirms receipt.
2. One item is recorded under three different names. The most serious effect:
Splitting the item separates demand from the balance, and every inventory measure loses its meaning.
3. A large count difference is traced to parts issued out of hours with no document. The best remedy:
A procedure that blocks the work will be bypassed; the answer is to make documenting easy, not to forbid the need.
