A PRACTICAL GUIDE

How to use the Supplier Catalog Comparison Tool.

Catalog comparison needs an explicit matching key and change policy. Keep ambiguous matches separate from confirmed additions or removals.

Make the workflow fit your task.

Choose a stable matching key and align field meanings before comparing catalogs. Separate confirmed changes, additions, removals and ambiguous matches, retaining both old and new values for review.

What you provide
Two supplied catalogs and matching identifiers.
What you get
Added, removed and changed products with uncertain matches.

Decisions and troubleshooting.

Does an absent SKU always mean the supplier discontinued it?

No. The supplied update may be partial or filtered. Confirm coverage and the change policy before treating absence as removal.

Why are many records falsely appearing as new products?

Check key formatting, leading zeros and duplicate identifiers. Matching problems can look like widespread catalog changes.

Try it with your own source.
