Sync is easy on day one and quietly wrong on day ninety: a webhook is missed, a variant renamed, an edit lands in the wrong store. StoreTwin copies products, variants and stock one way, from the store that owns the catalogue to the store that sells it. Then it keeps checking: hourly for what changed, nightly the whole catalogue, field by field. Differences are named by product and field with both values, and repaired. Nothing is ever deleted, and nothing is copied until you approve it twice.

• Hourly and nightly checks compare both catalogues field by field
• Every difference is named by product and field, with the value from each store
• Nothing is ever deleted in either store, by design
• A product it cannot match with certainty waits for you instead of duplicating
• Stock is compared per location: the locations you choose, added up

A bad import or a wrong bulk edit can undo a day of work. StoreVault keeps point-in-time copies of your products, collections, content, inventory and themes. Restores are precise: pick one record, approve a plan that lists exactly what changes, and only that record is written. Any restore can be rolled back. Stored copies are re-read and compared with your live store, and the result is emailed either way. Orders and customers are archived and exportable, never called restorable.

• Restore one record after a bad edit, without touching the rest of the store
• Approve a plan first: see exactly what will change before anything is written
• Undo a restore: the state before every write is saved automatically
• Emailed drills prove your backup works before you ever need it
• Export everything as JSONL or CSV, including orders and customers
