A bill of materials that's off by a little slips right past Business Central. No error, no warning. It just feeds wrong costs into every report downstream, and the system keeps handing you clean-looking numbers built on bad math.

In part 2 of 3, Business Central consultant Stephanie Clark, who came up as a cost accountant, follows a sloppy BOM all the way to a margin that doesn't match the bank account. She gets into why the data problems that hurt most are the ones the system never flags, what actually stops teams from getting BOMs clean, and why entering the same part into CAD, PLM, and ERP by hand is, in her words, death.
