Shopify price protection

Protect your Shopify store from dangerous pricing mistakes

Price Firewall monitors product price changes, detects risky updates, and can automatically restore the last safe price before a pricing error causes damage.

View documentationHow it works
Price Firewall catches a price change from 100 dollars to zero and restores the safe price

Pricing mistakes are quiet and expensive

Shopify accepts whatever price it is given. Price Firewall watches for the changes that are most likely to be mistakes.

Price set to zero

A variant that sold for $49 is suddenly free.

Large accidental drop

$100 becomes $50 after a typo or a wrong percentage.

Unexpected large increase

$80 becomes $200 and the product stops selling.

Invalid compare-at price

A compare-at price at or below the price shows a fake or negative discount.

Incorrect bulk edit or import

A spreadsheet or bulk edit changes many variants at once.

How it works

Monitor

Price Firewall tracks price and compare-at price changes on your product variants.

Detect

Rules compare every change with the variant's last safe price and identify suspicious ones.

Protect

Alert you by email, or on Pro automatically restore the last safe price.

Choose how much control you want

Safe

Alerts only. Suspicious changes are recorded and alerts can be sent. Prices are never changed automatically.

Protect Pro

Automatic protection with recommended safeguards: a price set to zero or dropped by more than 40% is restored automatically; other suspicious changes are reported.

Custom Pro

You choose the thresholds and the action (Ignore, Alert or Automatic rollback) for each rule.
