Start with a point-of-sale system that tracks inventory, not just sales. Square, Shopify POS, Lightspeed, and Clover all have inventory features built in. When you ring up a sale, the system should automatically reduce your stock count. If your current POS only processes payments, you’re missing half the picture.

Set up every product correctly from the beginning. Each item needs a SKU or barcode, a category, the cost you paid for it, and your selling price. The cost matters because that’s how you calculate actual profit margins. Entering products without costs means your reports look good but tell you nothing useful about which items actually make money.

Physical counts are unavoidable. Even with a perfect POS system, the count on your screen will drift from what’s actually on your shelves. Theft, damage, receiving errors, and cashier mistakes all create discrepancies. Most retail businesses should do a full physical count quarterly and cycle counts of high-value or fast-moving items monthly or weekly.

When you count, reconcile the differences. Your system says 24 units but you count 21. That’s shrinkage. Investigate why, adjust your system to match reality, and track the shrinkage rate over time. A climbing shrinkage percentage tells you something is wrong before it becomes a serious problem.

Connect your POS to your accounting software. Inventory accounting requires your books to reflect what you’re buying, selling, and holding. Most POS systems integrate with QuickBooks so inventory adjustments, cost of goods sold, and purchase orders flow automatically. Without this connection, you’re either duplicating data entry or your financial statements don’t reflect your actual inventory value.

Set reorder points so you don’t run out of popular items. Your POS should alert you when stock drops below a threshold. Stockouts cost sales and frustrate customers. Overstocking ties up cash in products sitting on shelves. The right reorder point depends on how fast items sell and how long your suppliers take to deliver.

Use your inventory reports to make decisions. Which items sell fast and which sit for months? What’s your actual margin by product category? Are certain items consistently showing shrinkage? These answers are in your data if you’re tracking inventory properly.

If you’re running a retail shop without real inventory tracking, you’re guessing at profits and ordering based on gut feel. That works until it doesn’t. Setting up proper tracking takes effort upfront but pays off in better margins, fewer stockouts, and books that reflect reality.

Most retail owners know they should track inventory better but don’t have time to set it up right. If that sounds familiar, getting help with the initial setup and ongoing bookkeeping services in the MetroWest area can get your systems working together so you can focus on running your store.
