A 3PL migration becomes difficult when stock figures disagree. The ecommerce platform, warehouse report and latest stocktake may each show different numbers, so the brand needs a reliable position before anything moves.
An inventory audit before exit creates a defensible closing position. The aim is to identify what should move, what should not move and which differences need explanation before the handover begins.
The safest approach is to check inventory before leaving a 3PL, rather than discovering unexplained differences after stock reaches the new warehouse.
Step 1: Freeze a reference point
Choose a specific date and time for the audit snapshot. Export SKU-level inventory from your ecommerce platform and request the corresponding warehouse report from the current 3PL. Include available, allocated, damaged, quarantined and returned stock where those statuses exist.
Open orders must also be separated. Units already allocated to customer orders should not be counted as freely transferable inventory.
Step 2: Standardise the SKU file
Old or duplicate SKUs can cause serious receiving problems at the new warehouse. Create a master list showing the correct SKU, barcode, product name, size, colour and status. Identify discontinued products and confirm whether they should be transferred, liquidated, returned or written off.
Step 3: Ask for physical verification
A system export is not a physical count. For valuable or high-risk lines, request a cycle count or full count before release. If the current provider will not perform one, decide which SKUs should be counted on arrival at the new facility.
Freckl’s inventory accuracy process describes barcode-scanned receiving, rolling cycle counts and discrepancy investigation. Whatever provider you choose, the incoming process should establish a clean opening balance rather than automatically copying the old number.
Step 4: Separate non-saleable stock
Damaged units, samples, marketing stock, returns awaiting inspection and obsolete products should be labelled separately. If these items are mixed with saleable units during transport, they can accidentally become available for customer orders.
Make a decision for every non-saleable category before collection. Moving clutter to a new warehouse only increases freight and receiving work.
Step 5: Reconcile packaging and consumables
Branded mailers, boxes, tissue, inserts, labels and gift packaging are inventory too. Count them and decide what will transfer. Missing packaging can delay go-live even when product stock arrives perfectly.
Step 6: Build a transfer manifest
Create a manifest for each pallet or shipment showing carton count, SKU range and expected quantities. Number the pallets and retain copies of dispatch documents. When the new 3PL receives the transfer, differences can then be traced back to a specific load rather than investigated across the entire range.
A structured 3PL migration plan should connect this stock work with the integration, cutover and testing schedule. Inventory is only one workstream, but it is the workstream most likely to cause oversells if it is treated casually.
A useful discrepancy rule
Do not silently overwrite differences. Record the expected figure, received figure, variance, investigation result and final adjustment so discrepancies can be explained and repeated problems identified.
Conclusion
A clean exit starts with knowing what you own and where it is. By standardising SKUs, separating stock statuses, physically verifying important lines and using detailed transfer manifests, a brand gives its new 3PL an accurate starting point instead of an inherited mystery.
FAQs
1. Should a brand perform a full stocktake before switching 3PLs?
Not always, but high-value, fast-moving and historically inaccurate SKUs should be physically verified. Larger discrepancies may justify a full count before stock leaves the existing warehouse.
2. What inventory reports should the outgoing 3PL provide?
Request SKU-level on-hand stock plus allocated, damaged, quarantined and returns statuses. Also request open-order information so committed units are not mistakenly included as transferable stock.
3. What happens if stock received by the new 3PL does not match the old report?
The variance should be logged and investigated before the opening balance is finalised. Shipping documents, open orders, late returns and physical counts can help explain the difference.
4. Should obsolete stock be transferred?
Only if there is a reason to keep it, migration is a good opportunity to dispose of obsolete, damaged or unsaleable inventory rather than paying freight and future storage for it.
5. Do packaging materials need to be included in the audit?
Yes. Branded packaging, inserts and labels can be essential to fulfilment. Count them separately and make sure sufficient quantities reach the new warehouse before go-live.
