How a North American custom & electric vehicle manufacturer got real-time margin visibility with Odoo

The challenge

Running multiple manufacturing plants alongside a national dealer network meant every vehicle produced a trail of disconnected data. Vehicle Identification Number (VIN) history, warranty registrations, and production tags lived in siloed spreadsheets, so manufacturing, dealers, and support teams often worked from different versions of the truth.

Actual costing for each custom vehicle sale, including manufacturing by-products, was calculated manually and only finalized at month-end. By the time a margin problem showed up, the vehicles were already sold. Dealer sales orders arrived through external platforms with no connection to the ERP, forcing staff to re-key every order by hand. Customer credit limits were checked manually, and without automated Positive Pay files for Wells Fargo, batch payment processing was slower and less secure than it needed to be. On the support side, warranty claims and RMA requests were not linked to specific VINs, so tracing a defect back to its production batch took days.

Why Odoo and Why GritXi?

The client needed one system that could handle vehicle-level manufacturing costing, warranty tracking down to individual VINs, and live integration with dealer platforms and banking, a combination that off-the-shelf automotive software does not usually offer together.

They chose Odoo 16 Enterprise because its manufacturing (MRP), inventory, and accounting modules could be extended into a true vehicle-level costing engine, instead of bolting on a separate automotive-specific system. They chose GritXi because GritXi had already built the specialized pieces this required (including VIN-linked warranty tracking, by-product costing logic, dealer API endpoints, and Positive Pay banking file generation) rather than proposing generic workarounds.

The approach

GritXi built a connected Odoo ecosystem covering the vehicle life cycle from production to aftermarket support:

VIN and warranty management

Every vehicle gets a centralized record tracking its VIN, production stage, tags, and warranty registration. Support and manufacturing teams see the same vehicle history without reconciling spreadsheets across departments.

Manufacturing costing and product lifecycle

By-products from manufacturing are automatically costed and allocated, so actual margin per vehicle is visible in real time rather than at month-end. Product Lifecycle Management (PLM) tools support iterative vehicle engineering as designs evolve. Quality alerts and scrap tracking are tied directly into shop floor operations, so defects are caught and logged where they happen.

Warehouse costing and inventory control

A dedicated costing engine calculates the precise actual cost of each vehicle sold. Cycle counts run on a dynamic schedule, and inventory updates are automatically blocked when discrepancies exceed a set threshold, preventing bad data from ever reaching the books.

Dealer APIs, credit control, and support

Secure API endpoints connect external dealer platforms directly to Odoo, so sales orders and product catalogs sync automatically with zero manual re-entry. Customer credit limits are checked in real time, placing orders on hold automatically if a limit or due balance is exceeded. Helpdesk tickets and RMA requests are linked directly to the VIN in question, so support staff can trace any issue back to its exact production record.

Banking integration

Positive Pay files for Wells Fargo are generated automatically, and batch payments run through a multi-tier approval workflow, reducing fraud risk and speeding up payment processing.

Implementation timeline

Total go-live timeline: 17 months from project start to full multi-plant production across 2 plants and 87 dealers.

The results

A story from the shop floor

A dealer reported a recurring electrical fault across a small batch of vehicles. Before Odoo, tracing which production run the affected VINs came from meant searching through paper build sheets and cross-referencing spreadsheets across two plants, a process that had previously taken close to two weeks and delayed a fix while more units shipped.

After go-live, the support team opened the Helpdesk ticket, linked it to the reported VINs, and immediately saw the shared production batch and component supplier in the vehicle record. The affected batch was isolated and a quality alert raised on the shop floor the same day, stopping further units from shipping with the same fault before the fix was in place.
