Sample: BOM Line-Item Cleanup for a Manufacturer
This worked example shows one BOM line-item cleanup run for a manufacturer. It covers the messy bill of materials that went in, the standardised version that came back, and the judgement a human reviewer applied so nothing was merged or guessed by mistake.
The bill of materials
The manufacturer exported a 140-line BOM that had drifted over time:
- Part numbers in three different formats.
- The same fastener described three ways by three suppliers.
- Missing units on some quantities.
- Two blank manufacturer fields, and a few rows where the part number and description had been swapped.
A BOM in this state quietly causes double-ordering and wrong quotes. Cleaning it by hand is a day nobody has.
What came back
The service returned a standardised BOM in the manufacturer’s own column order:
- One part-number format across every row.
- Deduplicated descriptions mapped to a single canonical name per part.
- Units filled where they could be inferred from context.
- A change log listing every edited row and the reason.
The change log matters: cleanup is only trustworthy if the manufacturer can see exactly what was altered, rather than receive a tidy sheet they have to take on faith.
What the reviewer caught
Merging is where automated cleanup goes wrong, so the review pass focused there:
- Three fastener descriptions were confirmed to be the same part before they were merged — not assumed.
- Two rows with part number and description swapped were corrected.
- Eleven rows where the intended part was genuinely unclear were flagged for the manufacturer, not guessed into a confident-looking value.
A wrong merge is worse than a flagged row, because it hides. Review keeps the ambiguous cases visible.
The deliverable
The manufacturer got a clean BOM in their own format, a change log they could audit, and eleven rows to confirm — instead of a day of manual deduping and the risk of a silent wrong merge.
BOMs vary in size and messiness, and how aggressively descriptions are merged is agreed at intake.
