Wholesale distribution businesses live and die by inventory accuracy. Your inventory is likely your largest asset, and getting the accounting wrong means your financial statements are wrong. That affects everything from tax liability to borrowing capacity to understanding whether you’re actually making money.

The foundation is a perpetual inventory system that updates quantities in real time as products move in and out. When you receive a shipment from a supplier, the system increases inventory and records the cost. When you ship to a customer, it decreases inventory and moves that cost to cost of goods sold. This continuous tracking gives you current inventory values without waiting for a physical count.

Your inventory management software needs to sync with your accounting system. Many distributors run separate warehouse management systems that don’t talk to QuickBooks or their ERP. That disconnect creates reconciliation nightmares. Every time inventory moves physically, the financial records should reflect it automatically or through a reliable daily process.

Valuation method matters more than most distributors realize. FIFO assumes you sell oldest inventory first and works well when costs are rising because it keeps lower costs in COGS and higher-value inventory on your balance sheet. Weighted average smooths out price fluctuations and is simpler to manage. The method you choose affects your reported profits and tax liability, and you can’t switch methods casually.

Landed cost is where many distributors get sloppy. The cost of inventory isn’t just what you paid the supplier. It includes freight, customs duties, handling fees, and any other costs to get that product into your warehouse ready for sale. If you’re recording inventory at purchase price and expensing freight separately, your margins by product are fiction. True landed cost gives you accurate product-level profitability.

Physical counts remain essential even with perpetual systems. Shrinkage happens through theft, damage, receiving errors, and shipping mistakes. Most distributors do a full physical count annually and cycle counts throughout the year. The count results get compared to system quantities, and the differences become inventory adjustments that hit your income statement.

Reserve for obsolete and slow-moving inventory is an accounting requirement that many businesses ignore until audit time. Products sitting in your warehouse for two years aren’t worth what you paid for them. A proper obsolescence reserve reduces inventory value on your balance sheet to reflect what you can actually sell it for. This is a judgment call that requires someone with controller-level oversight to evaluate quarterly.

The inventory section of your balance sheet should reconcile to your inventory system reports. If your accounting software shows $1.2 million in inventory but your warehouse system shows $1.15 million, you have a problem. These systems need to match, and investigating discrepancies promptly prevents small errors from compounding into major restatements.

Cost of goods sold calculation flows directly from inventory accounting. Beginning inventory plus purchases minus ending inventory equals COGS. If any of those numbers are wrong, your gross margin is wrong. And gross margin is the number that tells you whether your pricing and purchasing decisions are working.

Wholesale distribution businesses in South Florida often carry significant inventory values relative to their revenue. That concentration of assets in inventory means accounting errors have outsized impact. A 5% error in inventory valuation on a business carrying $2 million in stock is a $100,000 misstatement on your financial statements.

The businesses that manage inventory accounting well have clear processes for receiving, counting, adjusting, and valuing. They reconcile frequently rather than discovering problems at year end. And they have financial oversight that catches issues before they become material misstatements.
