How to stop rebuilding BOMs in Excel

Rebuilding a BOM in Excel after CAD approval is a second design process — slower, and usually wrong in one cell. Spectr generates the BOM from the design file so engineering, purchasing, and the shop share one product list.

Key facts

  • The Excel BOM is almost never the same revision as the PDF on the wall.
  • Purchasing from a typed list is how you order the wrong color or the wrong core.
  • Spectr’s design flow is built to kill that retype step.
  • Once products exist, inventory allocation and cutlists hang off the same records.

How shops handle this

  1. Ban “just this job” takeoffs
    One exception becomes the process.
  2. Generate from CAD in Spectr
    Issue products the shop can scan.
  3. Make Excel an export, not a source
    Analysts can still pivot. The floor cannot.
  4. Measure rework that started as a typo
    That number is your business case.

Common questions

Our estimator still needs Excel.

Estimating can stay there. Awarded, approved drawings should not go back into a blank workbook.

What if CAD is messy?

Fix the issued drawing once. Do not launder a messy model through a messier sheet.
