An ERP for engineered-to-order manufacturers.
If every order is designed before it is built, you run an engineered-to-order (ETO) shop. ARKcelerate handles the design → approve → build → ship loop without forcing it into a catalogue-product model.
The problem
ETO breaks catalogue-based ERPs.
Engineered-to-order and make-to-order work starts with engineering: a customer specification becomes drawings and a custom bill of materials, the customer signs off, and only then is it fabricated and commissioned. Catalogue ERPs assume the BOM already exists and never changes — the exact opposite of ETO reality.
So the most important parts of the job — the custom BOM, the approval round-trips, the engineering changes — end up tracked outside the ERP, and the system you paid for can no longer tell you what an order truly cost or where it stands.
How it works
Built for the design-to-dispatch loop.
A custom BOM per order
Build the bill of materials for each engineered item — no forcing a one-off into a catalogue product that does not exist.
Customer drawing approvals
Track every drawing revision and customer sign-off; the approved version drives the QC inspections downstream.
Change-safe revisions
Engineering changes version the BOM without breaking the manufacturing orders already in production.
Quote-to-cash on one project
A CRM quote becomes a project, a manufacturing order, a dispatch and an invoice — one thread from enquiry to payment.
Actual-vs-estimate costing
Because everything is tagged to the project, you can compare what the order was quoted at against what it actually cost.
FAQ
Common questions.
What is an engineered-to-order (ETO) ERP?
An ETO ERP is built for manufacturers who design each order before building it. It supports custom BOMs, customer drawing approvals, engineering changes and project-based costing, rather than assuming a fixed catalogue of products.
What is the difference between ETO and make-to-order (MTO)?
Make-to-order builds a known design only after an order is placed; engineered-to-order designs (or significantly re-engineers) the product for each order. ARKcelerate supports both, since both revolve around a per-order project rather than a stock product.
How are engineering changes handled?
Engineering changes version the bill of materials. Manufacturing orders already released keep their version, so a change never silently rewrites work already on the floor.
Is it suitable for project-based manufacturing in general?
Yes. Engineered-to-order is one shape of project-based manufacturing — see our project-based manufacturing ERP page for the broader picture.
