Maintain a record of all correspondence and quality reports for future reference. To prevent recurrence, review and reinforce quality control procedures with the supplier, and consider implementing incoming inspection protocols at your end. Building strong supplier relationships and clear contractual clauses can streamline dispute resolution.
