Engineer-to-Order (ETO) ERP Software
Built for the operational pattern most ERPs were never designed for — engineering, procurement, and production happening concurrently on a single contract, with change orders that ripple through partially-built work.
Engineer-to-order manufacturers face an ERP problem most platforms can't solve: the BOM doesn't exist when the work order opens. Engineering designs while procurement orders long-leads while production starts the structural work — and a customer change in week 8 ripples through everything in flight. Generic ERP assumes the BOM exists at order entry. ETP-specialized vendors usually charge enterprise pricing for the privilege.
Volvsoft builds custom ETO ERP for US manufacturers of capital equipment, custom industrial machinery, marine vessels, large-format fabrications, and other true engineer-to-order operations. We model concurrent engineering and procurement, late-stage BOM evolution, and contract-level cost accumulation as first-class data — not as awkward customizations on top of a make-to-stock platform.
What you get
Concurrent engineering & procurement
Long-lead procurement starts before BOM is final. Material reservations against engineering progress, not finished BOM.
Late-stage BOM evolution
BOM grows and refines over the life of the contract. Effectivity dates honor what's already in production.
Project-based job costing
Costs accumulate per contract across all engineering, procurement, fabrication, assembly, and commissioning activities.
Change order management
Customer change orders priced, routed, approved, and propagated through engineering, BOM, schedule, and production.
Engineering-to-production workflow
Released drawings flow from CAD/PLM to ERP. Routing definition follows engineering release. No re-keying.
Percent-complete revenue
ASC 606 / IFRS 15 compliant percent-complete revenue recognition tied to the actual work-in-process state.
Why ETO breaks generic ERP
ETO operations have a structurally different planning rhythm than make-to-stock. The places generic ERP fails are predictable:
- MRP assumes complete BOMs. ETO MRP needs to plan from incomplete-but-evolving BOMs
- Job costing assumes a defined operation sequence. ETO operations are defined progressively
- Inventory allocation assumes order at receipt. ETO procurement happens before sales-order entry sometimes
- Engineering changes are exception flows. ETO change orders are the operational norm
- Revenue recognition assumes shippable products. ETO often uses percent-complete with milestone billing
Engineering integration
ETO ERP that's not tightly integrated with engineering systems creates more work than it saves. We integrate at the data layer.
- PLM — Windchill, Teamcenter, Aras, Solidworks Manage (BOM and revision source)
- CAD — SolidWorks, Inventor, Creo, NX (drawing and assembly link)
- Engineering calculations — MathCAD, Excel, custom configurators
- Document control — engineering release with effectivity to production
- Change order flow — engineering to procurement to production with rollup tracking
Project accounting requirements
ETO operations need project accounting that most manufacturing ERPs treat as an afterthought.
- Cost accumulation per contract / project across all phases
- Estimate-at-completion (EAC) and estimate-to-complete (ETC)
- Percent-complete via cost-to-cost or milestones
- Customer billing by milestone, deliverable, or progress payments
- Backlog reporting at the contract level
Frequently asked questions
How does this differ from project ERP like Deltek or IFS?
Deltek and IFS are strong project ERP — and expensive. We're an alternative when the ERP-class pricing is unjustified for the volume, or when you need deeper manufacturing-specific functionality than generic project ERP offers.
Can you handle commissioning and field service after delivery?
Yes. Field service module covers commissioning, warranty, and post-delivery service work. Service tickets tie back to the as-shipped configuration for parts and service-bulletin matching.
What about percent-complete accounting?
ASC 606 / IFRS 15 compliant. Cost-to-cost or milestone-based percent-complete with revenue recognition entries posted to your GL of choice.
How does this work with our existing engineering tools?
We integrate, not replace. Engineering stays in PLM and CAD; ERP receives BOM and routing as engineering releases them. The data flow is one-way (engineering → ERP) for design data, two-way for cost and schedule data.
