In the aggregates sector, where precision is not optional but essential, Gravas y Derivados, commercially known as Grader, has been making a difference since 1965. This family business from Castellón, also a national benchmark, has been committed to quality and innovation since its foundation. And it was precisely this desire to innovate that led them to take the next step: digitizing their processes and centralizing all their management on a single platform.
The challenge was no small feat. Grader needed to unify scattered tools, eliminate manual tasks, and gain traceability and control, especially in critical areas such as scales, vehicle fleet, contracts, and invoicing.
Its goal: more efficient, connected, and error-free operations.
For its part, Transgrader, its subsidiary dedicated to waste rental and management, was looking for a solution that would allow it to manage sales and rentals accurately and automatically, with customized rates and detailed tracking of containers and services.
Odoo: the ERP that adapts to you
After analyzing different options, the Grader team was clear: they needed an ERP that adapted to their business, not the other way around. That's why they decided to take the plunge with Odoo. Its open-source nature and the flexibility offered by apps such as Studio made it the perfect choice for Grader.
Odoo, together with Nexta DS, was the perfect combination. A flexible, modular, and powerful platform that allows you to connect all processes, eliminate duplication, and obtain a global view of the company in real time.
The solution: customized digitization
Nexta DS is Odoo's official partner responsible for implementing Odoo at Grader. Nexta DS has configured a fully customized Odoo environment for Grader and Transgrader, focused on automation and operational control.
Scales connected in real time
They connected the scales directly to Odoo. When a truck is weighed, the system automatically collects the data and generates a sales order based on the weight received.
Fleet, trailers, and load control
They digitized the entire logistics circuit, including:
Registration of trucks, trailers, and drivers, with their updated information.
Tare and total weight control, including alerts if the limit is exceeded.
Integration with cameras and scales to manage the entry, exit, and loading of trucks in an automated way.
Contracts, delivery notes, and invoicing
They automated the flow from order to invoice:
Contracts are generated automatically with the order information.
Delivery notes can be printed directly from orders.
Carriers can digitally sign delivery notes from a trackpad, further streamlining the process.
Customized contacts
They modified the contacts module to adapt it to the customer's actual operations:
Construction sites appear as billing addresses.
Depending on the labels, contacts are displayed in different locations within the system.
Customized maintenance and work orders
They created a maintenance system tailored to their needs:
Operators record tasks, sections they work on, and kilometers traveled.
Mechanics can indicate what materials they have used and how much stock they have consumed.
All of this is linked to the vehicles, with comprehensive control of preventive and corrective maintenance.
Customized forms and documentation
They also adapted the system's forms and documents (such as delivery notes and contracts) to fit their operations and legal requirements.
Transgrader: waste management and rental, hassle-free
Nexta DS also designed specific solutions for Transgrader, Grader's rental and waste management subsidiary. Because no two businesses are alike.
Sales tables by service type (delivery, exchange, collection).
Smart rental: billing starts 30 days after actual delivery, not registration. If removed earlier, no charge.
Container tracking: full control of movements with a view tailored to your operations.
Customized rates: each customer has their price negotiated annually, and if there is a special one, it always prevails.
The result: efficiency, control, and connected growth
With Odoo and Nexta DS, Grader and Transgrader have taken the definitive leap into digital management. Thanks to their joint efforts, Grader now has complete centralization of all information in a single ERP; automated and traceable processes; reduced errors and greater efficiency; and absolute control of every movement.
All these improvements have streamlined Grader's daily operations, allowing them to have greater control, faster decision-making, and an immediate overview of their company.
Now, the company is not only a leader in aggregates, but also in technology, vision, and smart business management.
Grader would recommend working with Odoo for its ability to connect processes and people, as well as drive growth. They would also recommend working with an official Odoo Partner to adapt the software and tailor it to your needs.
