How to Stop Spare Parts from Bleeding 30% Out of Your Workshop?
How to Stop Spare Parts from Bleeding 30% Out of Your Workshop?
The Hidden Problem Destroying Your Revenue
In an auto repair shop, spare parts management is a delicate balance between always having the necessary pieces and not accumulating dead inventory. On one hand, the customer arrives with a breakdown and needs the replacement available NOW. On the other hand, each part purchased and not sold is tied-up capital weighing on your shelves and your balance sheet.
The situation is even more complex when considering that spare parts have limited shelf life, many are incompatible with each other, and vehicle models change constantly. A shop can have hundreds of parts on its shelves, but not know which ones actually generate income, which are obsolete, or which are at the exact reorder point.
According to industry data, 20-30% of the value of spare parts in inventory at mechanical workshops is tied up or obsolete. This means if you have $10 million in parts, between $2 and $3 million are not generating any return. Meanwhile, business opportunities are lost because the replacement needed is not available.
But there's more: without traceability, it's impossible to know if a part installed in a transmission 6 months ago is working properly. If the customer returns with the same problem, was it because the part was defective or because the problem was something else? Without serialization, that answer is a mystery.
The Solution: Intelligent Spare Parts Management with Kardex Tauro
Kardex Tauro transforms spare parts management at your auto repair shop with powerful tools such as Warehouse Location, Add Serials, Create Shrinkage and Kits - BOM, designed specifically to address the unique challenges of the automotive sector.
With Kardex Tauro, every spare part in your workshop has a story: where it came from, how much it cost, how many units you have, exactly where it is located, when it was sold, and which vehicle or customer it was installed in.
How to Implement Full Spare Parts Control
The system offers several key features:
- Warehouse Location: Assign exact addresses to each spare part (Warehouse, Row, Column, Level). A new employee can find any piece in seconds without asking the expert.
- Part serialization: Record the serial number of each individual spare part (especially for high-value items like alternators, injectors, ECUs). If a part fails, you can trace exactly which batch it came from and avoid future problems.
- Batch control: If a spare part has an expiry date (such as oils, seals, or adhesives), record the batch and expiry date to rotate inventory correctly.
- Shrinkage management: If a part is damaged, lost, or found to be incompatible, record the exact cause with the Create Shrinkage window. You can identify loss patterns and take corrective actions.
- Kits and labor: If you perform complete maintenance, use the Kits-BOM window to define which parts are included in each service and control the profitability of each type of work.
Comparison: Workshop Without Control vs. Workshop with Kardex Tauro
| Situation | Without Control | With Kardex Tauro |
|---|---|---|
| Find a spare part | Employee asks the "expert" or searches for 20 minutes | Query exact location → find in 2 minutes |
| Defective part | No one knows where it came from or which batch | Full traceability of batch and supplier |
| Inventory turnover | 25% of parts never move | Low-movement alerts → promotion or reassessment |
| Theft loss | Found in monthly inventory | Shrinkage source "theft" → document with responsible person |
| Maintenance sale | Cannot track which parts are used | Pre-defined kits → cost and profitability control |
Real Workflow: Reception, Use and Control
The complete process with Kardex Tauro is intuitive and secure:
- Receiving parts: When receiving a purchase order, the system opens Add Serials automatically for items with serial numbers. Record the batch and location of each part.
- Storage: Assign an exact location in the warehouse. The system generates labels with the code and location.
- Use in repair: When invoicing a service, the system automatically deducts the used part from inventory and links it to the vehicle and customer.
- Tracking: If a part fails after installation, query the serial and check the complete history.
- Audit: Movement from outputs and shrinkage are recorded with cause and responsible person, ready for analysis.

Real Use Case: "El Maquinista" Workshop
This 12-employee mechanical workshop in Guadalajara implemented Kardex Tauro for managing its 800 parts in inventory. In the first month, they reduced parts search time from 15 minutes to 3 minutes thanks to warehouse location. In the second month, they identified 47 obsolete parts representing 12% of the total inventory value, which they would never have detected otherwise.
By implementing serialization for high-value parts (alternators, injectors, ECUs), they managed to track exactly which parts were installed on each vehicle. When a customer returned with a defective alternator 3 months later, they were able to identify the exact batch and contact the supplier for a free replacement, avoiding a cost of $180,000.
Beyond that, by recording shrinkage with specific causes, they discovered that 25% of losses were due to parts being incorrectly installed. They implemented a verification checklist and reduced that percentage to 5%, saving more than 20% in non-billable parts.
How to Prevent Parts from Being Lost?
The Create Shrinkage window is your best ally for maintaining control:
- Internal theft: If an employee takes a part, record the shrinkage with cause "theft". The system deducts stock and records the value lost.
- Damage during use: If a part is damaged during installation, record the cause and the responsible person.
- Incompatibility: If you discover that a part does not fit the vehicle, record the cause and avoid future purchases of the same item.
- Expiry: For parts with an expiry date, record the cause "expiry" and the system will track it automatically.
Conclusion: From Chaos to Full Control
In an auto repair workshop, every part without traceability is an invisible wound in your cash flow. Every hour spent searching for a piece is an hour not making money. Every defective part misidentified is a frustrating return with the customer.
Kardex Tauro not only helps you have spare parts at the right time, but also helps you understand which parts to have, how many, where, and when to reorder. It gives you full visibility into each piece, from its reception to its installation in a specific vehicle.
