How do I prove my cold-chain deliveries meet customers' temperature requirements?

Start with the promises. For each customer, write down what they expect, in their words, and where it is stated: a contract, an email or a verbal arrangement. Make sure your own notes match theirs. If two customers have different expectations for the same product, say so plainly.

Next, pair each promise with its proof. Pull temperature logs, delivery times, alarm notes, device checks and the steps your drivers follow. Take a sample of several deliveries per customer and put the evidence side by side. Explain any gaps before the buyer finds them, and show what you changed afterwards.

Then make it easy to follow. Put the set in a folder with an index and a one-page description of your routine. Add short notes about any complaints and how you settled them. A buyer’s adviser will test a few deliveries from start to finish, so be ready for that. Ask your lawyer to review how you describe your obligations, so you do not promise more than your contracts say.

Key takeaways

• Write each customer’s expectation in their words, and note where it is stated.
• Pair every promise with logs, times and alarm notes for sample deliveries.
• Explain gaps yourself, and show what changed after them.
• Index the folder so a buyer can follow it without you, and keep a copy for yourself.
