On-Time In-Full. It is a supply chain metric used by major retailers to measure supplier performance. You must deliver the exact quantity ordered (In-Full) within a specific delivery window (On-Time).

How much safety stock should a food brand carry?

It depends on the shelf life of the product and the lead time of the manufacturer. For ambient products with a 12-month shelf life, brands typically carry 4 to 8 weeks of safety stock. For short-shelf-life refrigerated products, safety stock might only be 1 to 2 weeks.

Can a retailer fine me for a stockout if it was my co-packer's fault?

Yes. The retailer's contract is with your brand, not your co-packer. You are responsible for the OTIF fines, though you may try to pass those fines back to your co-packer if your manufacturing agreement allows it.

The True Cost of a Stockout for CPG Brands

When a food brand stocks out of a core SKU, the immediate reaction is to calculate the lost revenue. If you sell 1,000 units a week at $5 each, a two-week stockout costs $10,000. But that calculation only captures a fraction of the true financial damage. In grocery retail, the ripple effects of a stockout can cripple a brand for months.

1. The Retailer Penalty (Fines and De-listing)

Major retailers do not tolerate empty shelves. Walmart, Target, and Kroger enforce strict OTIF (On-Time In-Full) requirements. If you fail to deliver the full quantity ordered, you will be hit with a chargeback, often 3% to 5% of the cost of the missing goods.

Worse than the fine is the threat of de-listing. Retailers allocate shelf space based on velocity. An empty space generates zero velocity. If you stock out frequently, the category buyer will simply replace you with a competitor during the next category review. You lose the shelf space permanently.

2. The Destruction of Slotting ROI

You likely paid tens of thousands of dollars in slotting fees to get your product on that shelf. The ROI on slotting fees is calculated over years of continuous sales. If you are de-listed due to stockouts, your slotting investment drops to zero. You paid for real estate you are no longer allowed to occupy.

3. The Distributor Out-of-Stock Spiral

If you sell through UNFI or KeHE, a stockout creates an administrative nightmare. When the distributor stocks out, the independent grocery stores that order from them don't receive your product. Those store managers assume your product is discontinued and remove your shelf tag.

When you finally get product back into the distributor's warehouse, the stores don't automatically start ordering it again. Your sales team has to call every single store manager, explain the stockout, and convince them to put the tag back up. A two-week stockout can cause a six-month dip in velocity.

4. The Expedited Freight Tax

To fix a stockout, operations teams panic. They pay their co-packer a rush fee to produce a batch over the weekend. They pay for expedited LTL freight (or even air freight) to get the product to the distributor. These emergency logistics costs destroy the gross margin on the product you are rushing to sell.

Preventing the Stockout

Stockouts are rarely caused by a sudden, unpredictable spike in demand. They are almost always caused by a disconnect between the sales forecast and the purchasing team. Preventing them requires operations software that automatically translates sales forecasts into Material Requirements Planning (MRP), factoring in the lead times of your slowest ingredient suppliers.
