Know the cost of a design change before approving it.
DeltaLedger connects engineering changes to inventory, work in progress, purchase commitments, and supplier terms—then turns the evidence into a decision.

Watch one change become a defensible financial decision.
See the manufacturing problem, the signed-in workspace, the AI Exposure Analyst, and the leadership decision layer in one minute.
One source of truth
Engineering, procurement, operations, and finance review the same frozen evidence.
Confidence, made explicit
Known, estimated, and unresolved figures stay separate from calculation to report.
Value that survives the meeting
Every mitigation and realized outcome remains traceable after the change closes.
One example is the proof. The workspace runs every change.
A subscription is not a collection of static reports. It is the operating system for importing changes, resolving evidence, working with suppliers, approving decisions, and proving value across the entire portfolio.

“Which active changes depend on unconfirmed supplier cancellation terms?”
Illustrative portfolio preview · fictional data
From change to decision
Five teams. One connected decision record.
Engineering
The change is proposed and diffed.
Current and proposed BOMs are imported and compared. A replacement — one part swapped for another — is always paired explicitly by an engineer, never inferred.
Procurement
The commitments are made visible.
Open purchase orders, supplier cancellation terms, and exchange rates are brought in alongside the BOM — the commercial fact base exposure is calculated from.
Operations
Identity is resolved, exposure is calculated.
PLM part numbers are mapped to ERP part numbers with a confidence score. Every dollar of exposure is then classified — known, estimated, or unresolved — with full evidence behind it.
Finance
Mitigation is tracked to a real outcome.
Cancellations, redirections, and negotiated outcomes are recorded against the frozen figures — cost avoided versus loss realized, never blended.
Executive
The evidence becomes a decision.
A report leads with the conclusion, then the confidence, then the next step — with every supporting figure still one click from its source.
What this means in practice
A complete operating layer for engineering-change exposure.
Engineering change management
Import current and proposed BOMs and get a deterministic diff. A replacement — one part swapped for another — is always paired explicitly by an engineer, never inferred.
Financial impact analysis
Every dollar of exposure is calculated against real open purchase orders and classified — known, estimated, or unresolved — so a number is never presented with more certainty than the data actually supports.
Cross-functional collaboration
Engineering, procurement, supply chain, and finance work from the same evidence inside one workspace — not a spreadsheet stitched together after the fact from four separate exports.
Decision support & cutover planning
Model different cutover strategies against real on-hand inventory, WIP, and open PO terms, and see the financial and operational consequence of each before committing to one.
Traceability & auditability
Nothing is ever edited in place. Corrections supersede prior records, and every action is recorded in an append-only audit trail — a defensible answer to "how did we get this number," months later.
Executive Briefing
A leadership view brings financial exposure, priority decisions, supplier concentration, and realized value together across the active portfolio.
Value Ledger
Projected mitigation, accepted loss, cost avoided, and realized outcomes remain traceable across every change — creating an evidence-backed record of value delivered.
Executive decision package
A decision-ready report leads with release readiness, confidence, effectivity, and the material plan, with every supporting figure traceable to its source.
Start with one decision
The full workspace is the destination. The $500 sprint proves the route.
Bring one agreed engineering change. In three business days, receive a line-level exposure register, evidence gaps, one effectivity or mitigation scenario, and an executive decision record. Activate a workspace within 30 days and the sprint fee is credited.
