Can I compare a BOM before creating an account?

Yes. BOM Compare lets anonymous visitors use the sample demo and run one real browser-local comparison before creating an account.

Are raw BOM files uploaded by default?

No. BOM Compare processes files locally in the browser by default and does not store raw BOM files unless a future customer-controlled storage feature is explicitly enabled.

Does the Team trial require a credit card?

No. The 7-day Team trial is described as no-credit-card-required.

Compare a revised BOM

Use the guided flow to load an original export, load the revised export, confirm columns, and export a revision-impact report.

Picture guide

The first report, step by step.

These are the exact checkpoints most teams need: load two exports, confirm the columns, then export the revision-impact report. No raw file rows are stored by default.

1. Load two exports

Choose the original BOM and the revised BOM. The files are read in your browser.

2. Confirm columns

Match item number, quantity, description, unit, and any group column you use.

3. Export the report

Review added, removed, and quantity-changed material before material moves.

Common fixes

If something looks off, check these first.

Most first-run issues come from export shape: extra header rows, renamed columns, duplicate detail rows, or lines that need review before handoff.

The column match looks wrong

Open column review and choose the item number, quantity, unit, and description columns yourself. If the export has extra header rows, remove them before uploading.

Rows need review

Rows need review when a line is missing a trusted item number, has a low-confidence match, or has an unusual quantity. Review these before ordering or fabrication.

Duplicate rows appear

Turn on cleanup and consolidation. BOM Compare separates repeated detail rows from actual added, removed, and quantity-changed material.

Before you contact support

Use `.xlsx`, `.csv`, or `.txt` exports with one header row.
Make sure both exports use the same item number and quantity columns.
If duplicate rows appear, turn on consolidation before exporting the report.
For supplier quote checks, use the preview workflow only for review until it is ready for purchase-order decisions.

Still stuck?

Send the question, workflow, and the step where you got stuck. Do not send raw BOM or supplier quote files unless a controlled support process is explicitly arranged.
