Select multiple products and apply the same change — a price tweak, a description edit, a photo swap — across all of them at once, on every marketplace they're listed to.
There is no hard limit on how many listings you can put in one bulk edit. Closo queues the work and dispatches it at about 1 listing per second per marketplace to avoid rate-limit bans, and splits larger jobs automatically — so you can select your whole closet and let it run.
