In manufacturing, margin lives in the line items
Every part has a contracted price, a goods receipt, a supplier invoice, a standard cost, an actual cost and a customer order behind it. Every supplier has a rebate tier. Every tool and mold has an amortization schedule. Every shipment has a delivery note that may or may not match the invoice. The data lives across the ERP, MES, supplier portals, customer EDI and production records — and the variance between them is where the margin hides.
2–5%
Of supplier spend recoverable via rebates
3–10%
BOM cost variance between standard and actual
Years
Tooling amortization rarely tracked to completion
Structural failures in manufacturing finance
Margin is calculated component-by-component, supplier-by-supplier and tool-by-tool, and standard costs drift away from actual costs every day the BOM isn't reconciled.
Data Heterogeneity
ERP, MES, supplier portals and customer EDI all speak different languages
The ERP holds POs and standard costs. The MES tracks production and consumption. Supplier portals issue invoices in their own formats. Customer EDI sends delivery instructions and payment remittances. BOMs sit in a separate engineering system. None of these share a unified part-level identifier.
Every cost variance, rebate and three-way match starts with manual data assembly
Time Lag
Rebate periods, tooling amortization and BOM updates run on different clocks
Standard costs are updated annually, actual prices change weekly. Supplier rebate tiers settle at year-end, purchase volumes accrue daily. Early-payment discount windows close in 10–30 days while invoice variances are still being investigated. Finance teams miss windows that have already closed.
Discounts and rebates expire before variance can be resolved
Header-Level Blindness
Aggregate invoices and BOM rollups hide individual component-level variance
A €380K supplier invoice clears 3-way match at header until you open the lines: a price deviation on three component parts, a partial delivery billed in full, a missed early-payment discount. A standard-cost BOM rolls up to a clean unit cost until you compare it to actuals: one component drifted 11%, another supplier missed a rebate tier.
