FIELD GUIDE

What to measure in third-party fulfillment

A 3PL performs several jobs. Evaluate them separately before deciding whether the overall service works for your business.

Break down the work

Receiving, inventory control, picking, packing, dispatch, and returns each need a clear expectation. Ask what records demonstrate completion and which exceptions are excluded from a reported measure.

Check the customer consequence

Connect the warehouse result to a business outcome. A dispatch delay matters because it changes delivery expectations; an inventory mismatch can interrupt sales. Prioritize measures that help your team take a specific corrective action.

Follow one unit through the operation

Start with an incoming product and trace receipt, stock availability, order allocation, picking, packing, dispatch, and a possible return. Name the system record and human owner at each handoff. List the decisions your brand retains, such as replenishment, customer promises, and product instructions. This exercise helps turn a broad fulfillment service description into a division of work both teams can discuss.

Define a test before recording a score

Write the expected result, the sample, and the evidence you will accept. Keep a failed requirement separate from an unanswered question. Use the same test across providers where their proposed scopes are comparable. If the test changes, record why; otherwise an improved score may reflect an easier question rather than a better fit.

Use this question in your next meeting:
Which event changes the stock or order status, and who can resolve an exception?
