You need to change something across four hundred products - prices, a shipping class, a phrase in the title, a discontinued line. Doing it one at a time is a week of clicking and a week of mistakes.I do the bulk change properly: you tell me the rule in plain English, I apply it across the catalogue, and I show you exactly what changed before anything is committed. Formats stay consistent, variants are handled as variants, and anything ambiguous gets flagged rather than guessed.Step by step:You describe the change and the rule behind it.I run it in draft, send you the before/after list, and you approve.I apply it live and confirm the counts match your expectations.One bulk edit pass on one catalogue. Rules that differ per product, or anything touching prices at volume where a mistake is expensive, get a dry run you sign off first as standard.
