Workflow Comparison
Wire harness BOMs vs spreadsheets
The problem is not that spreadsheets cannot store a BOM. The problem is that spreadsheets do not naturally stay true to a live harness design.
Who This Page Is For
Engineers who keep BOM ownership in spreadsheets even though the harness design is changing every day.
Where Manual spreadsheet BOMs breaks
- Late connector and wire changes force manual BOM reconciliation
- Revision history is implicit and hard to audit
- Manufacturing sees a BOM that can lag behind the actual design decision
Where WireIt helps
- Treats the BOM as an output of the design workflow
- Improves trust that the released BOM matches the design state
- Reduces manual cleanup before procurement and production handoff
Where WireIt is not yet the best fit
- Spreadsheet export still matters for ERP and procurement handoff
- Teams with deep ERP customizations may need post-export shaping
