Changing US fulfilment warehouses: reconcile stock and open orders before cutover

Set the cutover decision and its owners

Changing a US fulfilment warehouse means moving physical stock while deciding which team completes each outstanding order. Set a cutover reference, a dated decision point with timezone, and owners for stock, orders, platform settings and customer communication. Define which SKUs and channels are included. Shopify is the example platform in this guide; confirm the software and operating arrangements that apply to your merchant account.

Aakash Modh's LinkedIn migration article provides a supplier-practitioner perspective on accountable owners and recorded approvals. Use those planning suggestions to name who can approve each change, then obtain acknowledgements from both warehouses. Record any work that must remain with the old team.

Give every open order line one fulfilment owner

Export or assemble the outstanding order lines through your agreed process. Keep the original channel order, line quantity, warehouse task, physical phase, current owner and latest instruction time. Separate unpicked, partly picked, packed and handed-over work. An order already partly fulfilled may need different decisions for its remaining lines; do not treat its order number as one indivisible task.

Before sending a line to the new warehouse, request an old-task stop and record the acknowledgement, affected quantity and actual goods location. A changed platform assignment cannot prove picking stopped. Where a stop is unconfirmed, keep that line with an exception owner instead of creating a competing instruction. Preserve previous labels and parcel references for any authorised rework.

Capture the stock baseline by state and location

Create a stock snapshot at the agreed timestamp, recording SKU, variant, sale unit, location and physical check depth. Compare quantities using the same unit: a supplier carton and an individual sale item need an explicit conversion. Include goods in pick staging and quarantine where they belong to the chosen location boundary. Retain both the recorded balance and any observed discrepancy.

Shopify's inventory adjustment history defines On hand as Available plus Committed plus Unavailable; Incoming is separate. An order reservation does not make a physical unit disappear. Record state totals beside the physical quantity, and identify who approves any difference. Inspect the relevant history by variant and location rather than forcing several screens to match an unexplained export.

Separate transfer paperwork from physical movement

Give each movement its origin, destination, SKU quantities, transfer reference and shipment reference. Retain departure counts, packing references and destination observations separately. Several shipments may belong to one transfer; a single summary status should not conceal a shipment still awaiting receipt. Agree how goods in transit remain excluded from the new warehouse's physical available stock.

Shopify documents Draft, Ready to ship, In progress and Transferred states. Ready to ship commits origin stock; In progress records destination Incoming. These platform states are not transport evidence. Its guidance reserves immediate Mark as transferred for goods already physically moved. Follow the workflow applicable to your account; the reviewed page does not establish every partial-receipt or in-transit cancellation procedure.

Reconcile a timed example before approving release

Use this invented planning exercise, with all times in UTC. At 13:00, SKU A has 120 units at the old warehouse: 18 committed, seven unavailable and 95 available. The approved movement is 80 of the available units. At 14:00, the departure check records 80, leaving 40: the 18 order units, seven held units and 15 residual units. The old warehouse retains the 18-unit order workload.

At 15:10, the destination count records 79 against the movement's 80. Record a one-unit discrepancy with a receiving reference and review owner. Do not create the missing unit to match the plan. The 79 observed units and old-site 40 are confirmed physical balances; one remains unresolved. Decide separately whether the checked destination units can be released while the discrepancy is investigated. These quantities illustrate reconciliation, not a real customer case.

Review location settings before accepting new work

Shopify's location guidance says a new location defaults to allowing online fulfilment and joins the end of the routing list. Check those settings against the intended cutover, together with product stocking and actual receipt approval. The transfer guide also warns that transferring inventory does not automatically activate products at the destination. Receiving a platform quantity and authorising fulfilment require separate checks.

Before deactivating the old location, review its default-location role, assigned orders and transfers, relevant permissions and app-location restrictions. Deactivation does not empty its inventory or document a physical stop. Obtain the warehouse's own acknowledgement. Keep any unsupported routing or order reassignment action as a question for the actual account owner rather than presenting a universal button sequence.

Keep returns and late receipts in the transition ledger

List expected replenishment and returns that may reach either address after the cutover decision. Give each a reference, expected destination, receiving contact and disposition owner. Confirm which published return instructions and outstanding authorisations need updating. Existing labels may still send a customer parcel to the old site, so agree how it will be identified, recorded and forwarded or held.

A refund does not authorise restocking, and a location setting cannot establish where a return arrived. Capture quantity, condition observation, physical location and the approved next action before changing availability. Shopify permits return restocking at an inactive location; therefore, an inactive old location should remain in the reconciliation until its residual receipts, held stock and outstanding work are resolved.

Release the agreed scope and review the first balance

Approve the cutover against recorded evidence. Select a first review time and compare new orders, old-owned work, movements, receipts and stock changes with the baseline. If a line is duplicated or a quantity is unresolved, stop the affected instruction and assign the next decision. Bring the ledger to a Jeton US fulfilment discussion so handling, communication and any connection work can be agreed for the project.

• Confirm one active instruction and one owner for each outstanding order line.
• Retain destination counts, discrepancy decisions and authorised releasable quantities.
• Check location availability and routing against the approved physical scope.
• Keep residual stock, returns and first-review exceptions assigned until closed.
