Shopify rates your shipping by product weight — but it never tells you which products have missing or wrong weights. Reweigh finds them, shows you the money at risk, and fixes them in bulk.
A blank or wrong weight means Shopify quotes the wrong price at checkout — so you either scare buyers off with inflated rates, or eat the difference on every order. Multiply that by your busiest SKUs and it's real money.
No spreadsheets, no editing products one by one.
Reweigh walks your whole catalog and flags every product with a missing, implausible, or duplicated weight — then estimates the monthly revenue at risk.
Each issue comes with a suggested weight and the reasoning behind it — from category data, title keywords, or AI for the tricky ones. You stay in control.
Fix one product or hundreds in a click. We double-confirm before writing, you can undo instantly, and every change is logged.
Bulk changes to a live store are serious. Reweigh treats them that way.
Missing, implausible, and duplicate-variant weights — caught automatically and ranked by the revenue they put at risk.
Category and keyword matching handle the common cases; an AI tier estimates the rest, always labelled so you know the source.
Applied something you didn't mean to? Revert the whole batch instantly — the reversal is recorded too.
A full audit trail of every weight change — who applied it and when — so an accidental edit is never a mystery.
Let Reweigh re-scan your catalog automatically so new and edited products never ship with bad data.
Use intentional weights for rate tiers? Dismiss those products and they stay out of every scan and bulk action.
