A quickly delivered wrong reference can delay a repair more than a transparent later commitment for the correct item. Review performance with the parts counter and qualified workshop team together. ## Define a correct delivery Compare the item, condition, source description and quantity with the accepted offer. Record approved substitutions separately from unreviewed differences. A part that fills the order line numerically should not count as complete if its suitability remains unresolved. Preserve the workshop's technical enquiry and any clarification history. A mismatch may result from incomplete vehicle information as well as supplier error, and the review should identify the evidence before assigning responsibility. ## Track availability and communication Measure delivery against confirmed stock and timing commitments, not a provisional estimate that was never accepted as firm. Record how early the trader warned of shortages or source changes. Useful notice can allow the garage to replan a job even when the original item becomes unavailable. For example, a trader may report high dispatch performance while repeatedly changing the offered condition after order. The service review should make those changes visible rather than count every parcel as successful fulfilment. ## Review return and core closure Track wrong-item returns, fault assessments and exchange-core credits with their relevant dates and next actions. Distinguish the supplier's response from a technical assessment that requires evidence. Keep physical collection and financial closure separate. Look for recurring issues by part family or sourcing route. Do not infer a product defect or authenticity problem from incomplete data; refer material technical concerns to qualified investigation. ## Use the results to refine the approved range Identify categories the trader handles well and areas requiring tighter enquiry or receiving controls. A supplier may be dependable for routine consumables but less suitable for special-sourced mixed-condition assemblies. Preserve that distinction rather than rely on one overall score. Agree specific actions such as clearer condition descriptions, earlier availability confirmation or a core-return register. The objective is a more predictable repair supply process, with technical decisions supported by accurate information. A useful review reduces avoidable returns and uncertainty rather than rewarding rapid delivery while the garage repeatedly absorbs the cost of correcting the order. ## Related buying guides - [Spare-parts quotation warning signs for UAE workshops](/blog/spare-parts-quotation-warning-signs-for-uae-workshops)- [Receiving workshop parts and recording exchange cores](/blog/receiving-workshop-parts-and-recording-exchange-cores)- [How to choose a UAE spare-parts trader for an independent garage](/blog/how-to-choose-a-uae-spare-parts-trader-for-an-independent-garage)[Browse all Auto Spare Parts & Accessories guides](/blog?category=Auto%20Spare%20Parts%20%26%20Accessories).
