VayaSoft implemented Odoo ERP to bring these activities together on one platform. The solution connected the complete process — from lead generation and quotation to solar installation, project completion, invoicing, and AMC service. This helped the company manage residential, commercial, and industrial solar projects with better visibility and control.
Key Challenges

The company faced several challenges while managing its solar EPC and installation operations:

Scattered Business Data

Customer, quotation, project, purchase, inventory, and service information was maintained in different systems or spreadsheets.

Difficult Project Tracking

It was difficult to track the progress of multiple solar installation projects, their activities, deadlines, and responsible teams.

Material Management Issues

Solar panels, inverters, batteries, mounting structures, cables, and other materials needed to be planned and tracked accurately for every project.

Site Survey Management

Site survey information such as customer requirements, installation location, capacity, and technical details was not connected properly with the quotation and project.

Procurement Delays

Purchase requirements were often identified manually, making it difficult to ensure that the required material was available before installation.

Field Team Coordination

Installation and service teams needed better visibility of assigned jobs, schedules, site details, and pending activities.

Billing & Payment Tracking

Invoices, project payments, advances, and outstanding amounts were difficult to track along with project progress.

AMC Management

After installation, managing warranty and AMC activities, service requests, scheduled maintenance, and customer history required additional effort.

Lead & CRM Management

Odoo CRM was used to manage enquiries from residential, commercial, and industrial customers.

  • New solar enquiries
  • Customer requirements
  • Follow-ups
  • Site survey requirements
  • Quotations
  • Sales opportunities
  • Conversion status

Solar Quotation & Sales

The sales team could prepare quotations based on the customer's solar requirements, including panels, inverters, mounting structures, batteries, installation services, and other required products or services.

Once the quotation was confirmed, the information could move directly into project execution and delivery processes.

Site Survey & Project Planning

Site survey information was connected with the customer and project, allowing the team to maintain important project details before installation.

Projects could then be planned with:

  • Project milestones
  • Installation activities
  • Responsible employees
  • Planned dates
  • Material requirements
  • Customer information
  • Project documents

Inventory & Material Management

Odoo Inventory was used to manage solar equipment and installation materials.

The company could track items such as:

  • Solar panels
  • Inverters
  • Batteries
  • Mounting structures
  • DC/AC cables
  • Electrical components
  • Installation accessories

Material movement from warehouse to project site could be tracked, providing better control over project consumption and stock availability.

Purchase Management

Odoo Purchase helped the company manage procurement based on project requirements. Purchase teams could create RFQs and purchase orders while maintaining visibility of required materials, suppliers, quantities, costs, and expected deliveries.

Installation & Field Service

Installation teams could manage site activities and service tasks through Odoo. Each project could have its own installation activities, assigned team members, planned dates, and completion status.

After installation, the same system could be used to manage customer service requests and maintenance activities.

Invoicing & Accounting

Odoo Accounting connected project activities with financial operations.

The company could manage:

  • Customer invoices
  • Advance payments
  • Project billing
  • Vendor bills
  • Payment tracking
  • Outstanding receivables
  • Project-related expenses

This gave management better visibility into both project progress and financial performance.

AMC & After-Sales Service

Once a solar project was completed, the customer could continue to be managed through Odoo's service workflows.

AMC operations could include:

  • Scheduled maintenance
  • Customer service requests
  • Preventive maintenance
  • Breakdown services
  • Service history
  • Warranty information
  • Technician assignment
  • Service completion tracking

This allowed the company to maintain a complete customer and installation history after the project was handed over.

Results

The implementation helped the solar company improve its overall business operations:

Centralized Operations

Sales, projects, purchasing, inventory, accounting, and service were managed through one ERP platform.

Better Project Visibility

Management could track solar projects from quotation through installation and completion.

Improved Material Control

Better visibility of project requirements, stock, and material movement reduced the chances of material shortages and unnecessary purchases.

Faster Project Execution

Connected workflows helped sales, purchase, warehouse, accounts, and installation teams work together more efficiently.

Better Field Team Management

Installation and service activities could be assigned and tracked from a central system.

Improved Financial Control

Project billing, payments, expenses, and outstanding amounts were easier to monitor.

Stronger After-Sales Service

AMC, warranty, maintenance, and service history could be managed from the same customer record.

Single Source of Truth

Management gained a complete view of customers, projects, materials, finances, and services without depending on multiple spreadsheets and disconnected systems.

Conclusion

A regional manufacturer of packaged snacks and spice blends replaced spreadsheet recipes, paper QC checklists, and a standalone billing tool with Odoo Manufacturing and Quality — bringing recipe control, batch traceability, and dispatch discipline into one system spanning purchase, production, and sales.
