Engineering change management software
Turn every ECO into a defensible decision.
DeltaLedger connects the BOM revision to inventory, WIP, open purchase orders, supplier evidence, and effectivity—so the change control board knows what is exposed, what can still be prevented, and what happens next.
ECO decision readiness
Evidence assembled
The missing decision layer
PLM controls the revision. ERP controls the transaction. DeltaLedger reconciles the decision.
Engineering change management breaks down when the technical change and the financial commitments already in motion are evaluated in separate systems, spreadsheets, and meetings. DeltaLedger creates one governed record without replacing either system of record.
Reconcile the change
Compare the current and proposed BOM without hiding uncertain replacements or identities.
Calculate exposure
Connect affected parts to inventory, WIP, open POs, currencies, and supplier obligations.
Choose the cutover
Compare immediate, dated, and controlled-runout scenarios against the same evidence.
Execute the decision
Assign mitigations, collect supplier responses, secure approvals, and preserve outcomes.
Where DeltaLedger fits
Not another ERP or PLM replacement.
| Capability | PLM | ERP/MRP | DeltaLedger |
|---|---|---|---|
| Primary record | Product definition and revision | Transactions and material planning | Cross-system change decision |
| Usually answers | What changed? | What do we own, owe, and plan? | What will this change cost and what should happen next? |
| Financial exposure | Often partial or external | Available but separated from engineering context | Reconciled per change with evidence quality |
| Supplier resolution | Typically outside the change record | Purchase-order execution | Terms, responses, mitigations, and outcomes |
| Starting path | Implementation and data governance | Existing ERP configuration | Reviewed CSV/Excel exports or API |
Calculate ECO cost
Separate gross affected value from known, estimated, avoidable, and unresolved financial exposure.

One change. Two exports. One defensible decision.
Begin with a current and proposed BOM plus an open-PO export. Add inventory, WIP, supplier terms, and effectivity evidence as the decision requires it.

Questions buyers ask
Clear answers before you begin.
What is engineering change management software?+
Engineering change management software coordinates how a proposed product or process change is evaluated, approved, released, and traced. DeltaLedger specializes in the financial and operational decision before release: connecting BOM changes to inventory, WIP, purchase commitments, supplier evidence, effectivity, mitigation, and realized outcomes.
What is the difference between ECR, ECO, and ECN?+
An engineering change request (ECR) proposes and evaluates a change. An engineering change order (ECO) authorizes and controls its implementation. An engineering change notice (ECN) commonly communicates an approved change. Terminology varies by company, so DeltaLedger preserves the organization’s own identifiers while maintaining one evidence-backed decision record.
Does DeltaLedger replace ERP or PLM software?+
No. ERP and PLM systems remain systems of record. DeltaLedger closes the decision gap between them by reconciling engineering, purchasing, inventory, production, supplier, and finance evidence for each change.
Can a manufacturer begin without an ERP integration?+
Yes. A current BOM, proposed BOM, and open-purchase-order export are enough to begin. Guided CSV and spreadsheet imports make a controlled first analysis possible before an API or ERP connector is justified.
How does engineering change software calculate financial impact?+
It should connect affected part identities to on-hand inventory, WIP, open PO lines, currencies, supplier terms, effectivity timing, and recovery options. DeltaLedger keeps gross affected value, net exposure, avoided loss, and unresolved evidence separate.
Can DeltaLedger evaluate a historical ECO?+
Yes. A sanitized historical change is often the safest way to evaluate the workflow. The resulting decision record can be compared with what the company actually spent, recovered, or wrote off.
