Retail Product Sales in Salons: Tracking Cost of Goods Sold

For many successful salons and spas, retail product sales represent 15% to 25% of total revenue. From an accounting perspective, selling physical products introduces a layer of complexity that service-based businesses often struggle to manage: inventory tracking and Cost of Goods Sold.

Understanding COGS

When you buy a bottle of shampoo for $10 and sell it for $25, the $10 is your Cost of Goods Sold. Gross profit on that item is $15. The accounting challenge: you do not deduct the $10 when you buy the shampoo — you deduct it when you sell the shampoo. If you buy 100 bottles in December but do not sell them until January, the cost sits on your balance sheet as an asset (Inventory). It only moves to the income statement as an expense (COGS) when the sale occurs.

Why accurate COGS tracking matters

Many salon owners treat all supplier purchases as immediate expenses. If you buy $5,000 of retail products right before fiscal year-end and expense it all immediately, you artificially lower profit and underpay tax. The CRA strictly prohibits this — you must account for inventory still held at year-end.

Without accurate COGS, you also cannot determine true profit margins. If retail sales are $10,000 a month, but you do not know whether those products cost $4,000 or $7,000, you cannot make informed decisions about pricing, discounting, or purchasing.

The role of POS systems

Modern salon POS systems track inventory perpetually — every product scanned and sold is deducted from inventory and recorded as COGS. But the POS is only as accurate as the data entered. When a shipment arrives, the new inventory must be entered immediately, including any price changes. If a stylist takes a bottle of retail shampoo off the shelf to use at the backbar (for a service), it must be manually transferred out of retail inventory into professional supplies. Without that, retail COGS is overstated and inventory counts never match reality.
