Engineer‑to‑Order ROI

See how rule‑driven design automation slashes quote‑to‑cash by 50 % and pays back in 12 months.


Custom equipment builders regularly spend 60–80 % of engineering capacity on orders that differ only 10 % from previous jobs. Rulestream’s engineer‑to‑order (ETO) automation turns that overhead into margin.


Why Traditional ETO Hurts

  • Manual sizing and Excel BOMs slow quoting cycles.

  • Engineering bottlenecks push delivery dates.

  • Tribal knowledge walks out the door with senior staff.


Rulestream in Action

  1. Config‑price‑quote (CPQ) to CAD/BOM – Customers configure online; valid options generate 3D models, drawings and cost instantly.

  2. Rule‑based calculations – Sizing, clearances and compliance checks run automatically.

  3. Closed‑loop to ERP – Approved orders push clean BOMs and routings straight into SAP or Oracle.
