Before you move your stock, move the right information.

Moving stock is the visible part of changing a fulfilment provider. Moving the right information is what lets the next operation use that stock properly.

A transport booking does not explain which products are sellable, which orders have already been picked or which cartons contain several SKUs. Those details need an owner before the first transfer leaves. Treat the change as a series of handovers, with a clear record of what each party is expected to receive.

Start with a stock position everyone can explain

Ask for a stock file that separates available, allocated, damaged, returned and held goods. Agree when the figures were taken and which movements happened afterwards. A report is most useful when both teams understand what its statuses mean.

Then decide how the transfer will be checked. Will the receiving team count pallets, cartons or individual units? Will cartons remain sealed? What happens when an outside label and an inside quantity differ? These decisions affect the work, the timing and the confidence you can place in the opening balance.

Make the product master usable

A product name is not a complete warehouse instruction. Bring the SKU, barcode, unit of measure, dimensions, weight and relevant handling information together in a consistent file. Include a photograph or a clear description where similar variants could be confused.

Keep individual items, inner packs, master cartons and finished kits distinct. If a carton contains twelve sellable units, that relationship should be explicit. A system that sees one carton and an order that expects one item need a shared definition before they can work together.

Draw a line through orders already in motion

Choose a cutover method for new orders and a separate method for outstanding ones. An order can be received, allocated, picked, packed or dispatched. Those are different states, and each needs a decision during a move.

Agree who owns orders that are held, partly fulfilled or awaiting stock. Record how a cancellation or address change will reach the right team during the transition. Avoid leaving the same order active in two places without a clear instruction about which operation should fulfil it.

Bring the exceptions into the plan

Open returns, unidentified cartons, damaged stock and missing labels rarely become easier to understand after a transfer. List them before the move. Decide which goods can travel with the main stock and which need a separate review.

A short exception register can be enough: the item, the quantity if known, the question, the owner and the next action. Its purpose is to make unfinished work visible. It should not contain unnecessary customer information or become a substitute for the main stock record.

Test the orders that represent your business

Pick a small but meaningful set of test orders. Include your ordinary parcel, a multi-item basket, a branded pack and a wholesale order if those are part of the operation. Test an exception too: an unavailable item or a return needing inspection can reveal instructions that a straightforward order never touches.

Review the physical output as well as the data. Are the correct labels present? Does the kit contain the right components? Does the dispatch record contain the information your team needs? Agree who can approve a test and what must change before the operation starts.

Give the move a decision owner

The plan needs someone who can resolve questions across stock, customer orders, systems and commercial scope. A named contact on each side is more useful than a long email chain in which responsibility is unclear.

Keep the first operating period under review. Reconcile stock, inspect exceptions and revisit the work that differed from the original brief. A transition is complete when the agreed process is operating and the remaining issues have an owner, not simply when the transfer truck has arrived.
