Mastering Inventory Planning for CPG Brands

For scaling food and beverage brands, inventory is your largest use of cash. The goal of inventory planning is not simply to avoid stockouts; it is to optimize your cash conversion cycle. Holding excess inventory ties up working capital and increases the risk of expiration and write-offs, while running too lean exposes you to out-of-stocks and retailer penalties.

The Complexity of Multi-Node Supply Chains

As brands grow, their supply chains fracture across multiple nodes. You might have raw materials arriving at a port, packaging sitting at a 3PL, and finished goods being produced at two different co-packers. A basic inventory calculator cannot manage the lead times and transit times between these nodes. You need a dynamic system that tracks inventory in transit and allocates it to specific production runs.

Safety Stock vs. Working Capital

How much safety stock should you hold? The answer depends on the variability of your demand and the reliability of your suppliers. For a staple ingredient with a highly reliable domestic supplier, a two-week safety stock might be sufficient. For an imported organic ingredient with volatile transit times, a six-week safety stock might be necessary to protect production.

Moving to Material Requirements Planning (MRP)

When you reach the operational inflection point where spreadsheets can no longer handle your SKU complexity, the next step is implementing an MRP system. MRP takes your sales forecast, your current inventory levels, and your supplier lead times, and automatically generates purchasing recommendations—ensuring you buy exactly what you need, exactly when you need it.
