Edit prices and compare-at prices of thousands of products and variants. Filter the products, pick a rule, and see the exact before/after of every variant — how many will change, stay the same or are blocked — before anything is written. Every value is saved before it changes, so a task can be undone in one click while its backup is kept, with a warning if something moved since. Tasks run in the background within Shopify API limits and resume by themselves. Run as many tasks as you need.

• Before/after preview of every variant with change, no-change and blocked counts
• One-click undo while the backup is kept, conflicts shown first
• Price rules: percent, amount, fixed, compare-at, swap, cost-based, round to .99
• CSV export and import, with the same preview and one-click undo
• Background tasks that respect Shopify rate limits and resume after a throttle
