14-day free trial • billed by Shopify
What it does
- Shows estimated shipping rates in the cart — shoppers see shipping costs before they reach checkout.
- Destination selection (Country → Province/State) — shoppers choose where they’re shipping to. If a country requires a province/state, the widget will prompt for it.
- Postal/ZIP input for accuracy — shoppers can enter a Postal/ZIP code to get the most reliable estimate for their destination.
- Countries shown match your store’s shipping destinations — the country picker only shows destinations your Shopify shipping setup supports, so customers don’t try unsupported locations.
How it works
- Runs as a Theme App Extension and displays inside the cart or cart drawer.
- Uses your store’s existing shipping zones and rates in Shopify to generate estimates.
- If enabled, Geo-IP auto-detection can pre-fill an initial destination estimate and always falls back to manual selection/entry when needed.
- Merchants can choose a Readability size that fits their cart/drawer layout: X-Compact, Compact, Default, or Large.
- Privacy-safe — the app does not store customer addresses.
Key benefits
- Fewer surprises → fewer abandoned carts.
- Clear shipping costs earlier in the journey.
- Builds shopper trust before checkout.
- No developer time — install and go.
FAQ
Does FP1 – Cart Shipping Calculator work with my theme?
Yes. It’s designed to work automatically with most Shopify 2.0 themes without requiring edits.
Do I need to add any code or make theme changes?
No. The app installs as a Theme App Extension. After you enable it under App embeds in your theme, it appears in the cart without any code edits or Liquid changes.
Which countries appear in the country picker?
The picker is limited to destinations supported by your store’s Shopify shipping setup. If a country doesn’t appear, it usually means you don’t ship there (or it isn’t included in your shipping zones).
Why does it ask for a province/state sometimes?
Some countries require a province/state to accurately determine which shipping rates apply. If needed, the widget will prompt the shopper to select one.
Can shoppers enter their own Postal/ZIP code?
Yes. Shoppers can always enter a Postal/ZIP code manually. This is the most reliable way to show accurate estimated rates before checkout.
What is Geo-IP auto-detection?
Geo-IP is an optional setting. If enabled, the widget tries to estimate a shopper’s country/region from their IP address to speed up the first estimate. If it can’t, or if the estimate isn’t usable, shoppers can select their destination and enter a Postal/ZIP code manually.
Can I adjust the widget text size?
Yes. In the app’s Settings, you can choose a Readability size (X-Compact, Compact, Default, Large) to fit your cart page and drawer layout.
Does it support international destinations?
Yes, as long as your Shopify shipping setup supports those destinations. For best results, shoppers should select the correct destination and enter their Postal/ZIP code.
Does it slow down my cart?
No. It’s lightweight and designed to keep the cart fast and responsive while displaying estimated rates.
Is any customer data stored?
No. The app does not store customer addresses. Destination details are used only to retrieve an estimate, and final totals are confirmed at checkout.
How does billing work?
The app includes a 14-day free trial managed by Shopify Billing. You’ll be asked to approve billing to unlock the widget in your store. Charges begin after the trial unless you uninstall or cancel before that date. Uninstalling stops future renewals. Shopify doesn’t automatically prorate unused time in the current billing period.
