Odoo DMS for Multi-Branch Auto Dealer

How a 5-Branch Auto Dealer Group Centralised Operations with a Custom Odoo DMS

Fast-growing dealership groups often outgrow disconnected spreadsheets, WhatsApp groups, and legacy DMS software long before they realise it.

This case study shows how a multi-brand automobile dealer group operating across five branches unified operations, improved reporting visibility, and accelerated decision-making with a custom Odoo DMS implementation.

Within six months of go-live, the group achieved faster monthly closing cycles, better inventory visibility, and a measurable improvement in lead-to-delivery conversion.

At a Glance

• Industry: Automobile Dealership (Multi-Brand, 5 Branches)
• Region: Western India
• Implementation Timeline: 14 weeks
• Modules Implemented: CRM, Sales, Inventory, Accounts, Service, HR, Custom DMS Dashboard, WhatsApp Integration
• Result: Unified reporting across all branches with faster operational visibility

The Story Behind the Transformation

The client operated five dealership branches across two states, selling both new and pre-owned vehicles while also managing a large service business.

By 2025, the group was selling more than 250 vehicles every month, but management still lacked a real-time view of operations across branches.

Each branch relied on its own spreadsheets, WhatsApp groups, and a legacy DMS that did not connect properly with accounts or inventory.

Monthly business reports were only available by the middle of the following month after heavy manual consolidation.

The leadership team realised the business could not continue scaling efficiently without a unified operational system.

The Operational Challenges

During the discovery phase, several operational gaps became immediately visible across branches.

• No shared inventory visibility between branches
• Sales leads routed manually over calls and WhatsApp
• Customer follow-ups managed through personal employee phones
• Test drive bookings maintained in branch notebooks
• Service records disconnected from vehicle sales history
• Accounts teams struggling with delayed reconciliation and branch consolidation

The lack of a single source of truth created delays, duplicate work, lost sales opportunities, and poor operational visibility.

Why the Client Chose a Custom Odoo DMS

The dealership group evaluated multiple off-the-shelf DMS solutions but found them expensive, inflexible, and poorly suited for multi-branch workflows.

The client specifically wanted:

• A single integrated system across all departments
• Custom workflows aligned with existing operations
• Predictable long-term software costs
• The flexibility to scale as more branches opened

Odoo’s modular architecture allowed the system to be customised around the dealership’s actual workflows instead of forcing the business to adapt to rigid software limitations.

How the Implementation Was Executed

Phase 1: Discovery & Process Mapping

The implementation began with detailed workflow mapping inside branches and head office operations.

Every sales, service, inventory, and accounts process was documented to identify duplication, delays, and manual dependencies.

Phase 2: Configuration & Customisation

Odoo CRM, Sales, Inventory, Accounts, Service, and HR modules were configured with branch-level controls and custom workflows.

Key custom developments included:

• Unified DMS dashboard with live branch reporting
• Automated WhatsApp confirmations for test drives
• Inter-branch inventory transfer workflows
• Linked service and sales history records
• RTO and finance tracking workflows

Phase 3: Data Migration & Training

Historical customer, inventory, and accounting data was migrated into Odoo with audit tracking.

Training sessions were conducted branch-wise for sales teams, service advisors, accountants, and management staff.

Phase 4: Go-Live & Hyper-Care

The rollout happened branch by branch over a controlled 10-day go-live period.

Sunray engineers remained onsite during the initial rollout phase to resolve issues quickly and support user adoption.

The Results After Six Months

Operational Improvements

• Monthly closing reduced from 12–15 days to 3–5 days
• Lead-to-delivery conversion improved by approximately 25%
• Inter-branch inventory visibility reduced lost sales significantly
• Automated WhatsApp reminders reduced test drive no-shows
• Service retention improved with linked customer history

Management Improvements

• Directors gained access to live operational dashboards
• Management meetings shifted from reconciliation to decision-making
• Accounts teams saved nearly 60 hours per month
• Customer data remained within the organisation instead of personal devices

Cultural Improvements

One of the biggest changes was operational alignment between branches and head office.

Instead of debating whose numbers were correct, every team worked from the same live system and the same operational data.

Key Lessons from the Project

Walk the Floor Before Configuring

Real dealership workflows are often very different from what gets described in meetings.

Roll Out Gradually

Branch-wise rollout allowed the project team to identify issues early without disrupting the entire group.

Integrate WhatsApp into Daily Operations

Automotive sales teams already operate heavily through WhatsApp. Integrating it into approvals, reminders, and customer communication dramatically improved adoption.

Build for Future Expansion

Because Odoo is modular, the dealership group can now add new branches and business verticals much faster.

What This Means for Other Dealer Groups

For dealership groups operating multiple branches, disconnected systems eventually become a growth bottleneck.

A properly implemented Odoo DMS creates one operational backbone across CRM, inventory, service, finance, and management reporting.

The result is faster decisions, cleaner data, improved customer experience, and operational scalability.
