In the automotive retail sector, fixed operations particularly the service and parts departments are a major contributor to dealership profitability. For dealers managing high-volume workshops, improving the efficiency of these operations is essential to maintaining profitability when vehicle sales fluctuate.

One of the most important indicators of workshop efficiency is service turnaround time (TAT): the time between a customer’s vehicle being received and the completed vehicle being invoiced and returned.

When vehicles spend unnecessary time waiting for parts, technician assignment, customer approval, warranty processing, or final checks, workshop throughput declines. Bay utilization suffers, technician productivity falls, and customers may face longer wait times.

For dealership groups operating across Latin America (LATAM), including Mexico, Brazil, Colombia, and Chile, these challenges can become even more complex. Multi-location operations, fragmented inventory, regional tax requirements, disconnected systems, and manual processes can create additional delays.

They require a comprehensive automotive workshop management module integrated within a unified Dealer Management System (DMS).

For dealer networks looking to improve workshop productivity at scale, Excellon Dealer Management System provides an integrated platform designed around the operational needs of automotive dealerships and dealer networks.

Why Service Turnaround Time Matters for Automotive Dealers

Service turnaround time is more than a workshop performance metric. It directly affects workshop capacity, customer experience, technician productivity, and dealership profitability.

Consider a vehicle that requires only 30 minutes of diagnostic work. If the service advisor then spends two hours waiting for customer authorization and another hour waiting for a required part, the vehicle’s total turnaround time becomes significantly longer than the actual repair time.

This highlights an important principle:

Reducing workshop TAT is not simply about making technicians work faster. It is about eliminating the waiting time between operational activities.

A dealership can increase throughput without expanding its physical workshop by reducing these unnecessary delays.

The objective is therefore to identify where vehicles, technicians, parts, and approvals are waiting and then connect the processes responsible for those delays.

Wrench Time vs. Idle Time: Where Workshops Lose Productivity

To systematically reduce TAT, workshop managers must distinguish between wrench time and idle time.

1. Wrench Time

The actual time a technician spends actively diagnosing, servicing, or repairing a vehicle. This is value-generating time.

2. Idle Time

Idle time is the period when a vehicle is waiting for the next operational step.

This may include:

• Waiting for vehicle reception or job-card creation

• Waiting for a service bay

• Waiting for technician assignment

• Waiting for parts

• Waiting for customer authorization

• Waiting for warranty processing

• Waiting for quality checks or final invoicing

In many dealerships, excessive idle time is caused by disconnected workflows.

When service advisors, parts teams, technicians, warranty personnel, and management rely on separate systems, spreadsheets, paper records, or manual communication, information has to move between people before work can continue.

A DMS addresses this problem by creating a connected operational environment in which information can move between departments as part of the same workflow.

Common Causes of High Automotive Workshop Turnaround Time

Before implementing technology solutions, dealership operations need to understand what is actually causing service delays. In high-volume automotive workshops, TAT is typically derailed by four recurring bottlenecks.

Four recurring operational challenges are particularly important.

1. Manual Vehicle Check-In and Paper-Based Repair Orders

In traditional workshops, service advisors may manually record vehicle information, customer complaints, inspection observations, and required work.

This creates several problems:

• Data has to be entered manually

• Information can be incomplete or inaccurate

• Vehicle history may not be immediately available

• Physical documents have to move between departments

• Technicians may wait for job information before beginning work

These seemingly small delays accumulate throughout the day.

How a DMS Helps

A modern DMS can digitize vehicle reception, service history, inspections, and repair-order workflows.

With Excellon DMS, dealerships can bring service-related information into a centralized dealership environment, helping service teams access relevant vehicle and customer information while reducing unnecessary manual handoffs.

The result is a more structured transition from vehicle reception → inspection → repair order → workshop execution.

2. Disconnected Parts and Service Operation

Parts availability is one of the most common reasons vehicles remain idle in workshops.

A technician may identify a required component, only to discover that the service team does not have immediate visibility into inventory. The parts department then has to check availability manually, locate the component, or determine whether it needs to be ordered.

If the part is unavailable, the repair can remain open while the vehicle occupies workshop capacity.

How a DMS Helps

An integrated DMS connects workshop and parts operations so that service teams can work with better visibility into parts availability.

An integrated DMS connects parts and workshop processes within the same dealership environment, helping dealerships coordinate service requirements with parts operations and reduce delays caused by disconnected information.

For multi-location dealer networks, centralized visibility can also help teams identify inventory available elsewhere in the network, where supported by the dealership’s operating model.

This changes the workflow from:

Technician requests part → service team checks manually → parts team searches inventory → vehicle waits

to:

Repair requirement identified → inventory visibility → parts coordination → repair proceeds

The fewer manual handoffs involved, the lower the potential for unnecessary waiting time.

3. Inefficient Technician Allocation

Not every repair requires the same technician expertise.

A complex diagnostic job may require a highly experienced technician, while routine maintenance can be handled by technicians with different skill levels. When work is assigned manually without a clear view of technician availability and workshop capacity, dealerships can experience:

• Technician idle time

• Uneven workloads

• Scheduling conflicts

• Underutilized bays

• Delayed repair completion

How a DMS Helps

Workshop management capabilities within a DMS can help managers organize repair orders, technician activity, and workshop capacity more systematically.

Excellon DMS provides dealerships with a centralized environment for managing workshop operations, helping managers improve visibility into ongoing work and coordinate service activities more efficiently.

The objective is not simply to assign more jobs. It is to ensure that available workshop capacity is used effectively while minimizing unnecessary waiting between jobs.

4. Delayed Customer Approvals

In traditional setups, obtaining authorization for additional repairs requires the service advisor to call the customer, leave a voicemail, and wait for a callback. During this waiting period, the vehicle occupies a valuable service bay while no active work is being performed, completely halting workshop momentum.

How a DMS Helps

A connected DMS can help service teams manage estimates, repair information, customer interactions, and approval-related workflows as part of the overall service process.

By reducing reliance on disconnected manual communication, dealerships can help move repair decisions forward more efficiently.

For dealerships using digital communication channels, these workflows can also support a more transparent customer experience by giving customers clearer information about recommended repairs and associated costs.

How a Dealer Management System Reduces Workshop Turnaround Time

The most effective approach to reducing TAT is to connect the operational processes that influence vehicle movement through the workshop.

1. Digitize Vehicle Reception and Vehicle Health Checks

The first opportunity to reduce delay occurs when the vehicle enters the dealership.

Electronic Vehicle Health Checks (eVHC) allow service advisors to capture inspection information digitally rather than relying entirely on paper-based processes.

A digital workflow can help service teams:

• Access vehicle service history

• Record inspection findings

• Capture relevant observations

• Share repair information with workshop teams

• Create or update repair orders

• Reduce repetitive data entry

With Excellon DMS, dealerships can centralize service-related information and create a more connected workflow from vehicle reception through workshop execution.

This helps reduce the administrative friction that can occur between the customer handover and the start of actual workshop activity.

2. Connect Workshop Scheduling with Technician Capacity

A workshop’s capacity depends on more than the number of physical bays.

Managers also need visibility into:

• Available technicians

• Current workloads

• Repair-order status

• Job progress

• Workshop capacity

• Technician productivity

A DMS can provide a centralized view of workshop activity, allowing managers to make more informed decisions about job allocation and workload.

With Excellon DMS, workshop operations can be managed within the broader dealership environment rather than relying on disconnected scheduling tools.

This gives dealership management greater visibility into where work is progressing, where operational delays are developing, and where workshop capacity may be underutilized.

3. Integrate Parts Inventory with Workshop Operations

Few things increase TAT more than a vehicle waiting for a part.

A connected DMS can provide visibility between workshop requirements and parts inventory, allowing dealerships to coordinate parts availability with repair orders.

The process can include:

Repair requirement identified → Parts availability checked → Part coordinated/reserved → Technician receives required component → Repair continues

For dealer networks operating multiple locations, centralized inventory visibility can provide another advantage.

If a part is unavailable at one location but available elsewhere in the network, the dealership can identify the potential source and coordinate the appropriate transfer process.

Excellon DMS is designed to support connected dealership operations across sales, service, parts, and other core functions, helping dealer networks reduce the operational gaps that can contribute to workshop delays.

4. Accelerate Customer Estimates and Repair Approvals

Customer approval is another point where workshop operations can stop.

A modern DMS can help service teams manage repair estimates and customer communication within a connected workflow.

Instead of treating the approval process as a separate administrative activity, dealerships can make it part of the service workflow:

Inspection → Additional repair identified → Estimate prepared → Customer informed → Approval received → Work continues

The objective is simple: reduce the time between identifying an additional repair and receiving the customer’s decision.

For dealerships, this can help keep vehicles moving through the workshop rather than allowing them to remain inactive while service advisors manually chase approvals.

5. Streamline Warranty-Related Workflows

Warranty repairs can introduce additional administrative steps into an already complex service process.

Service teams may need to validate coverage, document repairs, process claims, and coordinate with OEM requirements.

When these activities are handled through disconnected systems, warranty administration can become another source of delay.

An integrated DMS can connect dealership service activity with warranty-related workflows, helping service teams manage the required information more efficiently.

For OEM-authorized dealer networks, Excellon DMS brings dealership operations into a unified platform and supports connected OEM-oriented processes, helping reduce the administrative friction associated with service and warranty operations.

How Excellon DMS Helps Automotive Dealer Networks Reduce Workshop Turnaround Time

Identifying operational delays is only the first step. Solving them requires an infrastructure that connects every department in real time. This is where Excellon DMS offers a broader approach than standalone scheduling tools. By integrating service, parts, CRM, and accounting into a single platform, Excellon’s automotive workshop management software helps address the operational causes of idle time.

1. Mobile Vehicle Health Checks (eVHC)

The DMS equips service advisors with mobile capabilities to conduct electronic Vehicle Health Checks (eVHC) right at the vehicle. Instead of using a clipboard, advisors use a tablet to pull up the customer’s full service history instantly, capture photos or videos of required repairs, and generate a digital repair order in real-time.

Because Excellon DMS is a unified system, this data entry doesn’t just stay at the front desk. It is immediately pushed to the workshop floor. The assigned technician can review the diagnostic data and visual evidence before the vehicle even reaches their bay, shaving crucial minutes off the initial intake process.

2. Intelligent Bay and Technician Scheduling

Excellon’s workshop management module automates bay scheduling by aligning repair orders with technician skill sets, certification levels, and real-time bay availability.

Instead of a workshop manager manually assigning tasks on a whiteboard, Excellon DMS helps workshop managers coordinate repair orders with technician availability and workshop capacity. Technicians use the mobile interface to clock in and out of specific jobs. This provides management with precise data on standard time versus actual time, helping to identify training needs and workflow adjustments. By ensuring the right technician is on the right job at the right time, Excellon minimizes bay downtime.

3. Unified Parts Inventory and Predictive Ordering

A core strength of Excellon DMS is the seamless integration of parts and service workflows. When a technician identifies a necessary repair, they do not need to walk to the parts counter. They check parts inventory electronically from their bay workstation.

Excellon DMS immediately reserves the part in the warehouse, triggering a digital pick ticket for the parts department. If a part is out of stock, Excellon’s intelligent inventory algorithms analyse historical demand and lead times to generate predictive reordering alerts. This ensures high-turnover parts are always available when needed, directly reducing the dreaded “waiting on parts” status that destroys service turnaround times.

4. Automated Customer Communication via WhatsApp

To solve the customer approval delay particularly in the LATAM market where messaging apps dominate communication Excellon DMS features omnichannel CRM capabilities.

When a technician discovers that a vehicle needs brake pad replacements during a routine service, the advisor can trigger an automated WhatsApp message or SMS directly from the Excellon platform. The message includes an itemized digital estimate, a video or photo of the worn brake pads, and a simple approval link. This reduces the approval cycle from hours to minutes, keeping the vehicle moving through the service pipeline without tying up a service bay.

5. Streamlined OEM Warranty Claim Processing

Handling warranty repairs is historically heavy on administration. Excellon DMS integrates directly with Original Equipment Manufacturer (OEM) portals. This architecture allows the workshop to automatically validate warranty coverage, retrieve standard repair times, and submit structured digital warranty claims directly from the repair order. Automating this data exchange ensures the dealership gets reimbursed faster and reduces the time vehicles spend in the lot waiting for OEM authorization.

Addressing LATAM-Specific Workshop Challenges

Automotive dealer networks operating across Latin America face unique operational hurdles that generic scheduling tools simply cannot resolve. Managing high-volume operations across Mexico, Brazil, Colombia, and Chile requires an enterprise automotive DMS built for Latin America where cross-location inventory flow and stringent fiscal mandates directly dictate vehicle turnaround time.

• Multi-Location Inventory Visibility Across Dealer Networks

In multi-location dealer networks, a vehicle often sits idle in a bay waiting for a part that is out of stock locally, even if a sister branch in the same city has three on the shelf. An integrated platform for multi-location dealer management breaks down these operational silos. If a workshop in São Paulo or Bogotá needs a component, central inventory visibility allows service teams to instantly locate, reserve, and transfer stock across the network, keeping repair lines moving.

• Built-in Localization and Tax Compliance

A vehicle’s turnaround time does not end when the technician puts down their tools; the job is only complete when the vehicle is invoiced and handed back to the customer. In LATAM, administrative friction during billing frequently inflates total TAT.

Whether managing CFDI electronic invoicing within a dealer management system in Mexico or navigating complex tax structures within automotive dealer software in Brazil, manual calculations and disconnected accounting tools create severe delivery bottlenecks. By integrating localized tax compliance directly into the automated invoicing workflow, dealership groups can process payments instantly, ensure full regulatory compliance, and hand keys back to customers without administrative delays.

• Key Performance Indicators (KPIs) to Track for Workshop Efficiency

Implementing an automotive workshop management module like Excellon provides dealership leadership with real-time analytics to continuously monitor operations. To sustainably reduce TAT, management should monitor the following KPIs via their DMS dashboards:

• Technician Utilization Rate: The ratio of hours a technician is actively working on vehicles compared to their total available shift hours.

• First-Time Fix Rate (FTFR): The percentage of vehicles successfully repaired on the first visit without returning for the same issue. Excellon helps track this by linking repair histories to specific technicians and parts.

• Parts Fill Rate: The percentage of times a requested part is immediately available from the dealership’s internal inventory.

• Average Service Turnaround Time: The definitive measure of overall efficiency, segmented by repair type (e.g., routine maintenance vs. heavy repair).

Why Dealer Networks Need More Than Workshop Scheduling Software

Standalone workshop scheduling software can be useful for managing appointments and basic job allocation.

But workshop turnaround time is influenced by far more than the appointment calendar.

A vehicle can be scheduled perfectly and still experience delays because:

• The required part is unavailable

• The technician is not available

• Vehicle history is difficult to access

• Customer approval is pending

• Warranty information requires manual processing

• Finance and invoicing workflows are disconnected

• Another dealership location has the required inventory but the workshop cannot see it

This is the fundamental difference between basic workshop scheduling software and a comprehensive Dealer Management System.

A DMS connects workshop operations with the wider dealership ecosystem.

For dealer networks, this broader integration is critical because the objective is not simply to schedule more vehicles.

The objective is to move each vehicle through the dealership with less waiting, fewer manual handoffs, better information flow, and greater operational visibility.

Why High-Volume Dealerships Trust Excellon Software

Reducing workshop turnaround time requires more than isolated automation. It requires the service, parts, customer, warranty, and operational processes that influence vehicle movement to work together. This is where Excellon DMS provides value.

By connecting core dealership operations within a unified platform, Excellon helps dealer networks move from fragmented processes toward a more coordinated operating model.

The result is a foundation for:

• Faster vehicle reception

• Better workshop visibility

• Improved coordination between service and parts

• More efficient technician utilization

• Reduced administrative handoffs

• Better visibility across dealer locations

• More connected OEM-related processes

• Data-driven workshop performance management

For dealerships looking to increase workshop throughput without simply adding more bays or technicians, improving the flow of information can be one of the most effective places to start.

Final Thoughts

Reducing automotive workshop service turnaround time is not about forcing technicians to work faster. It is about eliminating the unnecessary waiting that occurs between operational activities.

Manual vehicle reception disconnected parts operations, inefficient technician allocation, delayed customer approvals, warranty administration, and fragmented multi-location processes can all contribute to longer TAT.

A modern Dealer Management System addresses these challenges by connecting the processes that move a vehicle through the dealership.

For automotive dealer networks, Excellon DMS provides a centralized platform for connecting workshop, parts, customer, OEM, and dealership operations. By reducing operational fragmentation and improving visibility across these processes, dealerships can create a more efficient service environment.
