Seven bulk editing mistakes

Bulk editing failures are remarkably consistent. Almost none of them are about the tool; they are about the selection, the arithmetic or the absence of a way back.

1. Trusting the filter without reading the preview

The rule is usually right. The selection is what surprises people. Read the match count, and read a sample of the products — especially at the edges of the filter.

2. Compounding percentages by accident

Three successive 20% cuts leave you at 51% of the original price, not 40%. If you have a margin floor, calculate the final stage from cost rather than applying another percentage.

3. Forgetting compare-at price

Cutting the price without setting the reference means no sale badge and no visible discount. Setting the reference without cutting the price means a discount that does not exist — which is worse.

4. No end time

A promotion without a revert time relies on a person remembering. Set both timestamps when you create the task.

5. Editing while a feed is running

If a sync app owns your inventory or prices, a manual bulk edit can be overwritten minutes later. Decide which system owns which field, and edit accordingly.

6. No way back

A CSV import with no prior export cannot be undone. If your workflow is file-based, take the export every single time, even when you are sure.

7. Changing handles without redirects

Shopify does not create redirects when a URL handle changes. Indexed pages and existing links simply break. Plan redirects before the task, not after the traffic drops.

The pattern behind all seven

Each one is a failure to check something that takes thirty seconds: the preview, the arithmetic, the second field, the timestamp, the owner of the data, the export, the redirects. Bulk editing is fast; the checks are what keep it from being fast in the wrong direction.
