Understanding Product Costs in Repairs:

1. Repaired Product (Main Product):
   • No Cost Update by Default: The cost of the repaired product is not automatically adjusted after a repair unless manually accounted for in accounting or inventory valuation.
2. Consumed Components (Parts Used in Repair):
   • These are logged as stock moves (internal transfer) if Consume Materials is enabled.
   • If using real-time inventory valuation and the product has a standard or average cost, the value is reduced from stock.
3. Invoicing the Repair:
   • If invoicing is enabled, the customer is billed for labor and/or parts, but it does not update the cost of the main product.

Workaround / Enhancement Options:

• Custom Module: Extend repair.order to update product cost manually after repair completion.
• Landed Cost Entry: Manually apply a landed cost on the product if parts/labor impact the value.
• Use of Manufacturing App: For complex costing, consider using the MRP app for rebuilds instead of Repairs.

Technical Tip:

Stock moves in the Repairs app are stored under stock.move linked to repair.order. You can review cost impact per move for parts used.
