Odoo for Engineering Firms
Engineering ERP: engineer-to-order projects, BOM revisions, and billable time
Talk to an engineering consultantEngineering work does not fit a catalogue
An engineering business sells a promise before the design even exists. The quote is really an estimate, the bill of materials shows up weeks later, and it typically changes twice more before anything ships. Catalogue-style ERP systems paper over this by assuming the design was already known at order time, and that mismatch is why so many engineering firms end up running the ERP for accounting while the real project lives in a spreadsheet.
Engineer-to-order without pretending the design exists
At quote time, a configured or bespoke product simply doesn't exist in any catalogue to pick from. Teams patch around that with placeholder products and manual adjustments, leaving the link between what was quoted, what got designed, and what was actually built dependent on whoever happens to remember.
Our engineer-to-order setup gives each project its own bill of materials, built after the order is placed and linked back to the original quotation. Because estimated and actual cost stay visible throughout the project rather than getting reconstructed afterward, a job that's going wrong shows up while there's still time to do something about it.
BOM revisions and change orders that stay traceable
Designs change, that's a given. But when revision control only lives inside the CAD system, purchasing can end up ordering parts against a superseded revision, production builds against a drawing that's already been superseded, and afterward nobody can say for certain which revision the delivered unit was actually built to.
With Odoo's engineering change orders, each bill-of-materials revision goes through an approval step and comes with an author, a date, and a reason attached. Purchasing and production always work from the current approved revision, while units built under an earlier one stay traceable back to it, and that traceability is exactly what makes a warranty claim or a field failure something you can actually investigate.
Billable time, fixed fee, and milestone billing
Engineering revenue rarely comes from one source, it's often a mix of hourly, fixed-fee, and milestone billing within a single project. If timesheets live in one tool and invoicing in another, utilization becomes a guess, and fixed-fee work ends up quietly subsidizing the hourly side without anyone noticing.
When timesheets, project budgets, and invoicing all run in one system, an approved hour turns into either a billable line or a cost against a fixed fee, depending on the rule attached to that task. Milestone billing gets scheduled against the project's stages, and utilization and realized rate become something you pull up as a report instead of piecing together every quarter.
What we implement for engineering firms
- Engineer-to-order projects with per-project bills of materials
- Engineering change orders with approval workflow and revision history
- Estimated against actual cost tracking, visible during the project
- Timesheets feeding billable invoicing, fixed fee, and milestone schedules
- Analytic accounting for profitability by project, phase, and engineer
- Document management linking drawings and specifications to the job
- Integration to the CAD or PLM system you already run
Bring us a project that went wrong
The most useful conversations tend to start with a job that lost money. Tell us where the estimate and the actual numbers diverged, and we'll show you which parts of that gap come down to a systems problem, and which don't.
Talk to an engineering consultantEngineering ERP: frequently asked questions
01
What is an engineering ERP?
It's an ERP configured for work where nobody knows the design yet when the order comes in. What sets it apart is project-level bills of materials built after the sale, revision control through formal change orders, per-project tracking of estimated against actual cost, and billing that can mix hourly, fixed-fee, and milestone models. None of that exists as a first-class concept in a catalogue-driven ERP.
02
Can Odoo integrate with our CAD or PLM system?
Yes, through the standard API. Typically the CAD or PLM system stays the authority on design and pushes released bills of materials and revisions into Odoo, while Odoo takes ownership of purchasing, production, and cost. Trying to flip that, making the ERP the design authority, is both the more common mistake and the costlier one.
03
How does Odoo handle change orders?
An engineering change order versions the bill of materials through an approval step, recording who changed what and why along the way. Purchasing and manufacturing then work from the approved revision, and units built earlier stay traceable to whichever revision they were built under, which is exactly what lets you investigate a field failure.
04
Can we track profitability per project?
Yes, analytic accounting handles that. Labor from timesheets, purchased materials, subcontracted work, and allocated overhead all post against the project, which means margin stays readable during the job instead of being assembled after the fact. Of everything we implement, this is usually the first change engineering firms actually notice.
