Stock Out Resolution SOP

Standard procedure for identifying, resolving, communicating, and documenting stock outs, including backorders, customer communication, expediting, and root cause review.

Steps

• Identify the stock out
  The inventory coordinator verifies that the item is unavailable by checking on-hand quantity, allocated quantity, open orders, and any pending receipts. Record the affected SKU, quantity short, location, and time discovered. If the shortage is confirmed, proceed to impact assessment.
• Assess customer and operational impact
  The operations manager reviews open orders, promised ship dates, production schedules, and service commitments to determine the impact of the shortage.
• Create or update backorders
  The customer service representative creates or updates backorders for affected orders and records the expected replenishment date if known. The representative flags any priority accounts or expedited orders for escalation.
• Communicate the shortage to affected parties
  The customer service representative notifies affected customers or internal stakeholders using approved communication language. Include the item name, impact, estimated resolution date if available, and next update time. Log the communication date, recipient, method, and summary in the contact record.
• Escalate urgent replenishment needs
  The procurement specialist reviews supplier lead times, alternate sources, transfer options, and available safety stock. The specialist expedites replenishment when the shortage threatens service levels, production continuity, or contractual commitments. Escalate to the operations manager if no replenishment path is available within the required tolerance.
• Document the resolution and root cause
  The warehouse supervisor records the resolution method, such as receipt of replenishment, transfer from another location, substitution, or order cancellation. The supervisor identifies the root cause category, such as forecast error, supplier delay, picking error, data mismatch, or demand spike. Record corrective actions, preventive actions, owner, and due date for any non-conformance.
• Verify closure and archive records
  The operations manager verifies that all affected orders are updated, customer communications are complete, and the root cause record is saved in the approved system. The manager confirms that the event is closed only after all required documentation is complete.
