COGS Controls UAE: Preventing Margin Leakage in Trading Businesses

Are your sales increasing while your gross margin is getting weaker? 

For UAE trading businesses, margin leakage can come from purchasing errors, inventory movements, landed costs, returns and incorrect cost allocations. Strong COGS controls UAE help ensure every product sold carries an accurate and properly supported cost. This improves gross-margin reporting, inventory valuation and financial decision-making while supporting reliable accounting records for UAE Corporate Tax calculations.

So, how can UAE trading businesses strengthen COGS and prevent avoidable margin leakage? Let’s explore the key controls.

What Is COGS in a Trading Business?

Cost of Goods Sold represents the cost associated with products that a business has sold during a particular period. For a trading company, COGS generally connects three key components:

Opening inventory + Purchases and directly attributable costs − Closing inventory = COGS

For example, suppose a UAE distributor starts the month with AED 500,000 of inventory, purchases AED 1 million during the month and finishes with AED 600,000 of inventory.

Its basic COGS calculation would be:

AED 500,000 + AED 1,000,000 − AED 600,000 = AED 900,000

If sales for the same period are AED 1.3 million, the gross profit would be AED 400,000 and the gross margin would be approximately 30.8%.

However, the calculation is only useful when the underlying purchasing, inventory and costing data is accurate.

The Federal Tax Authority’s Determination of Taxable Income guide also provides examples where cost of goods sold is presented as an expenditure in determining accounting income.

What Is Margin Leakage?

Margin leakage occurs when a business loses expected profit through costs, pricing issues, operational errors or transactions that are not properly controlled. In a trading business, some common causes include:

• Incorrect product costs
• Unrecorded freight or customs-related costs
• Incorrect inventory quantities
• Stock damage and unexplained shortages
• Purchase-price differences
• Incorrect sales returns
• Discounts not properly accounted for
• Wrong SKU or product mapping
• Duplicate purchase entries
• Incorrect inventory adjustments
• COGS posted to the wrong accounting period

For example, a company may believe that a product costs AED 100 because that is the supplier invoice price. But after freight, insurance and other directly attributable import costs, the actual landed cost may be AED 108.

If the product is sold for AED 120, the business may believe it is earning a 20% gross margin based on its purchase price. The actual margin is lower once the complete product cost is considered. This is why COGS controls should not be treated as a purely bookkeeping exercise.

Why COGS Controls Matter for UAE Trading Companies

Trading companies can have hundreds or thousands of SKUs, multiple suppliers, frequent imports and constantly changing purchase prices. Without appropriate controls, management may receive a gross-margin report that looks precise but is based on incomplete costing data.

Strong COGS controls can help businesses:

• Improve gross-margin accuracy
• Detect purchasing inefficiencies
• Identify unusual product-level losses
• Improve inventory valuation
• Detect stock discrepancies
• Monitor supplier pricing
• Reduce accounting errors
• Strengthen Corporate Tax documentation
• Support better pricing decisions

The UAE Ministry of Finance explains that accounting income is generally the starting point for determining taxable income, followed by the adjustments required under the Corporate Tax rules. This makes reliable accounting data particularly important for businesses preparing their financial statements and Corporate Tax computations.

Key COGS Controls to Prevent Margin Leakage

1. Match Purchase Orders, Goods Receipts and Supplier Invoices

One of the first controls should be a three-way matching process. The accounting team should compare:

Purchase Order → Goods Received Note → Supplier Invoice

The objective is to confirm that:

• The correct quantity was ordered.
• The correct quantity was received.
• The supplier billed the correct quantity.
• The agreed purchase price was applied.
• Any discrepancies are investigated before final posting.

For example, if a company orders 1,000 units at AED 50 each but receives only 950 units, an invoice for 1,000 units should not automatically be posted without investigation. Small differences repeated across multiple suppliers can materially affect inventory and COGS.

2. Capture the Complete Landed Cost

For UAE importers, purchase price alone may not represent the complete cost of bringing goods into inventory. Depending on the transaction and applicable accounting treatment, businesses may need to consider costs associated with importing and bringing inventory to its required location and condition.

Potential components can include:

• Supplier purchase price
• Freight
• Insurance
• Customs-related costs
• Clearing charges
• Other directly attributable costs

If these costs are excluded or incorrectly expensed, product-level margins can become distorted.

Example

A business imports goods with a supplier invoice value of AED 200,000. It also incurs:

• Freight: AED 15,000
• Insurance: AED 2,000
• Customs/clearing-related costs: AED 8,000

If the relevant costs are appropriately attributable to inventory, the accounting team needs to ensure they are captured consistently within the company’s costing methodology.

A product that appears profitable based only on the supplier invoice may therefore have a substantially different true margin.

3. Reconcile Inventory Subledger to the General Ledger

One of the most important COGS controls UAE businesses can implement is a monthly inventory-to-GL reconciliation. The inventory subledger should be compared with the relevant general-ledger accounts.

Investigate differences caused by:

• Manual journal entries
• Stock adjustments
• Goods received but not invoiced
• Invoices posted without receipts
• Returns
• Transfers between warehouses
• Damaged stock
• Duplicate transactions
• Incorrect SKU mapping

The reconciliation should not simply identify a difference. It should document why the difference exists and how it was resolved.

4. Perform Regular Physical Stock Counts

System inventory should be tested against physical inventory. A business can perform:

• Full physical stock counts
• Cycle counts
• High-value SKU counts
• Random warehouse checks
• Slow-moving inventory reviews

Suppose the system shows 5,000 units of a product, while a physical count finds only 4,900 units. The 100-unit difference needs investigation.

Possible causes include:

• Theft
• Damage
• Picking errors
• Unrecorded sales
• Warehouse mistakes
• Incorrect receiving
• Data-entry errors

Ignoring such differences can cause both inventory and COGS to become unreliable.

The Federal Tax Authority provides guidance on understanding taxpayer obligations and maintaining relevant tax information and records.

5. Control Sales Returns and Purchase Returns

Returns can create significant COGS errors if they are not processed correctly. For a customer return, the business should determine whether:

• The product is returned to saleable inventory.
• The product is damaged.
• The product requires inspection.
• The item must be written off.

A returned product should not automatically be treated as normal inventory. Similarly, supplier returns should be properly removed from inventory and reflected in the relevant supplier and inventory records.

A monthly return report can help identify unusual patterns by supplier, product or sales channel.

6. Monitor Purchase-Price Variances

Supplier prices frequently change. A business that purchases the same SKU at AED 40, AED 43 and AED 48 during different months should monitor those movements.

A purchase-price variance report can show:

SKU	Previous Cost	Current Cost	Variance
Product A	AED 40	AED 42	+AED 2
Product B	AED 75	AED 73	-AED 2
Product C	AED 100	AED 115	+AED 15

Large variances should trigger investigation. The business may need to determine whether the change resulted from:

• Supplier price increases
• Currency movements
• Different purchase quantities
• Freight changes
• Product specifications
• Incorrect invoice entry

This information is particularly useful for pricing decisions.

7. Review Product-Level Gross Margins

Company-wide gross margin can hide serious problems. Suppose a trading company reports a 25% overall gross margin. That does not necessarily mean every product line is profitable. One product may generate a 40% margin while another produces only 5%.

Therefore, management should periodically review:

Sales price − product cost = gross profit

and

Gross profit ÷ sales price × 100 = gross margin percentage

Product-level reporting can help identify:

• Underpriced products
• High-cost suppliers
• Loss-making SKUs
• Unexpected discounts
• Incorrect product costing
• Margin deterioration

8. Investigate Unusual COGS Movements

A monthly COGS variance report can identify problems before they become significant.

Management can compare:

• Current month COGS vs previous month
• Actual COGS vs budget
• COGS percentage vs sales
• Product margin vs target
• Purchase prices vs standard costs
• Inventory adjustments vs previous periods

For example, if sales remain relatively stable but COGS suddenly increases from 70% to 82% of revenue, management should investigate. The increase may be genuine, but it could also indicate:

• Incorrect inventory valuation
• Missing sales invoices
• Incorrect purchase posting
• Unrecorded purchase returns
• Stock shortages
• Wrong costing method
• Cut-off errors

9. Strengthen SKU and Master-Data Controls

Incorrect master data can create COGS problems without being immediately obvious. Each SKU should have clearly defined information such as:

• Product code
• Product description
• Unit of measure
• Supplier
• Standard or moving cost, where applicable
• Product category
• Warehouse
• Tax classification where relevant

Duplicate SKUs are particularly dangerous. If the same product exists under multiple codes, inventory may become fragmented and management may receive misleading margin information. Master-data changes should therefore be controlled and reviewed.

10. Apply Cut-Off Controls at Month-End

Month-end cut-off is another important area. The accounting team should confirm that purchases and sales are recorded in the correct accounting period.

For example, goods received before month-end but invoiced later may need appropriate accounting treatment under the company’s accounting policies.

Similarly, goods dispatched before year-end should not be left in inventory if the relevant sale has been recognised.

Incorrect cut-off can distort both:

• Inventory + COGS + Revenue + Gross Profit

for the reporting period.

COGS, Inventory and UAE Corporate Tax

COGS controls are primarily an accounting and management control, but accurate accounting records can also support tax compliance. The UAE Corporate Tax framework generally starts the taxable-income calculation from accounting income, followed by specified tax adjustments.

The FTA’s Determination of Taxable Income guide demonstrates COGS as an expenditure item and separately illustrates adjustments relating to unrealised inventory losses. This is an important reminder that accounting treatment and Corporate Tax treatment should not automatically be assumed to be identical in every situation.

Businesses should therefore maintain supporting records that allow COGS and inventory figures to be traced back to underlying transactions.

What Records Should a UAE Trading Business Maintain?

A strong COGS control environment should create an audit trail from the financial statements back to individual transactions. Depending on the business, this may include:

• Purchase orders
• Supplier invoices
• Goods received notes
• Shipping documents
• Customs documentation
• Freight and clearing invoices
• Inventory reports
• Stock-count records
• Sales invoices
• Credit notes
• Return documents
• Inventory adjustment reports
• General-ledger reports
• Bank/payment records
• COGS reconciliation schedules

The FTA has also issued FTA Decision No. 4 of 2026, covering rules and requirements for maintaining information contained in accounting records and commercial books. The decision was published by the FTA on 20 August 2026.

Businesses should review the official decision and applicable tax legislation to understand the requirements relevant to their circumstances.

A Practical Monthly COGS Control Checklist

Before closing each month, a UAE trading company can use the following checklist:

Purchasing

• Are supplier invoices matched to purchase and receiving records?
• Were purchase-price variances reviewed?
• Are missing invoices identified?

Inventory

• Does the inventory subledger agree with the GL?
• Were stock adjustments reviewed?
• Were physical counts or cycle counts performed?
• Are damaged and obsolete items identified?

COGS

• Is the COGS calculation supported?
• Were landed-cost components captured appropriately?
• Are product costs consistent with the company’s accounting policy?
• Were unusual COGS movements investigated?

Sales

• Are sales returns correctly processed?
• Are discounts and credit notes properly recorded?
• Is revenue recorded in the correct period?

Reporting

• Has gross margin been reviewed by product or business segment?
• Are loss-making SKUs identified?
• Have significant margin changes been explained?

This checklist can turn COGS review from a year-end exercise into a continuous management control.

Frequently Asked Questions

1. What are COGS controls?

COGS controls are accounting and operational procedures used to ensure that the cost assigned to goods sold is complete, accurate and properly supported. They can include purchase matching, inventory reconciliation, stock counts, landed-cost reviews, and margin analysis.

2. Why is COGS important for UAE trading companies?

COGS directly affects gross profit and gross-margin reporting. Incorrect COGS can make products appear more or less profitable than they actually are and can lead to unreliable management reports.

3. Should freight and customs-related costs be included in COGS?

The appropriate treatment depends on the nature of the cost and the applicable accounting framework and company accounting policy. Trading businesses should assess costs associated with bringing inventory to its required location and condition rather than automatically treating every import-related charge as a period expense.

4. How often should a company reconcile inventory and COGS?

A monthly reconciliation is generally a strong control for businesses with regular inventory movements. Higher-volume businesses may also benefit from weekly exception reporting or cycle counts for important SKUs.

5. Does accounting COGS automatically determine UAE Corporate Tax?

Not necessarily. Accounting income generally provides the starting point for determining taxable income, but Corporate Tax rules may require adjustments. The FTA’s official guidance should be reviewed for the specific transaction and circumstances.

Conclusion

For UAE trading businesses, margin leakage can remain hidden when COGS is treated simply as an accounting number rather than a controlled business process. Strong COGS controls UAE practices connect purchasing, landed costs, inventory, sales returns, stock counts and financial reporting so that management can see the real profitability of its products. Regular inventory-to-GL reconciliations, purchase-price variance reviews, physical stock counts, product-level margin analysis, and month-end cut-off checks can help identify errors before they become costly.
