Switching takes about thirty seconds. Open the Plan page in the app and pick the other plan. Upgrading to Pro shows Shopify’s standard approval screen; the moment you approve, Pro is on. Switching down to Free is even simpler: Free has no subscription, so there’s nothing to approve. The change is immediate either way, with no notice period, no support ticket, and no gap in coverage.
What actually changes
Your configuration never does. Rules, severities, custom messages, and blocklists carry over exactly as they are. The switch changes what’s enforced:
- Free → Pro turns on verification. From the next order, addresses are checked against carrier data and the buyer prompts start carrying the verified fix. Your rules keep working as before.
- Pro → Free turns verification off. Your rules keep enforcing on both surfaces — checkout blocks and the after-purchase warn prompts — and orders keep getting tagged and counted. What stops: addresses are no longer checked against carrier data, so typos pass unnoticed and prompts no longer carry a suggested fix. Charges stop entirely, since Free is never charged at all.
If you’re unsure which direction you should be going, Free vs Pro is the comparison.
About the $500 on the Pro approval screen
When you approve Pro, Shopify shows a $500 monthly maximum. This is not a fee and not something you’ll pay. Shopify requires every usage-priced subscription to carry a merchant-approved ceiling, so a runaway app could never bill you without limit.
Your actual cost is $0.04 per order, full stop. Reaching the $500 ceiling would take 12,500 orders in one month. If your store genuinely operates at that volume, email [email protected] and we’ll raise the cap (and talk volume pricing).
Billing mechanics worth knowing
- Everything bills through Shopify and appears on your regular Shopify invoice. We never hold your payment details.
- Free has no charge of any kind: no subscription, no order fees. Pro has no base fee either, just the $0.04 per verified order.
- Your first 100 orders are verified free regardless, and a plan switch doesn’t reset or consume that counter. How the trial works.
- Uninstalling the app cancels any subscription automatically. That’s standard Shopify behavior, and there’s nothing to cancel separately.
