Ask for an example invoice
Give the provider a typical month of orders and ask it to show how the charges would appear. Discuss storage, extra picks, packing materials, returns, and minimums in the same conversation.
Agree on how changes are handled
Your order mix will change. Ask how the account team flags new fees or work outside the original scope, who approves that work, and where you can question a charge. Keep the explanation with the quote.
Reconcile one example month
Choose a normal month and list the activities that should appear on an invoice. Include receiving, storage, picking, packing materials, shipping, returns, and project work where applicable. Ask how minimums interact with those charges. Keep the provider’s original fee names beside your own cost categories. This lets you check the arithmetic without losing the conditions attached to a line item.
Agree on how the teams will work
Use the brief to start a conversation with the people responsible for the account. Discuss where questions go, who owns a difficult answer, and how updates reach your team. Write down the arrangement in language both sides understand. The goal is a working agreement that still makes sense on a busy day, when the usual contact is unavailable or an order needs attention.
Use this question in your next meeting:
Can another person trace the proposed total to quantities, rates, and written assumptions?
