Install Calcurates, set up your first shipping method, and add Calcurates to your Shopify shipping profiles so rates appear at checkout. A basic setup takes a few minutes.

Before you start

Your Shopify plan needs the third-party carrier-calculated shipping (CCS) feature. Shopify counts any app that returns calculated rates as third-party shipping, including the custom rates you build in Calcurates. Without CCS, Shopify doesn't call Calcurates and doesn't list it as a rate app.

Step 1. Install Calcurates

1. Open Calcurates on the Shopify App Store.
2. Click Install.
3. Review the requested permissions and approve them.
4. Wait for the installation to finish. Your Shopify store connects to your Calcurates account automatically.

One Shopify store connects to one Calcurates account.

Step 2. Set up your shipping in Calcurates

1. In your Shopify Admin, open Apps > Calcurates.
2. Add at least one Origin, the location you ship from.
3. Create at least one Shipping Option and make sure it is enabled.

You can add Areas, Segments, Rules and advanced features later. Basic shipping configuration: steps to follow covers each one.

Step 3. Add Calcurates to your Shopify shipping profiles

Shopify doesn't add a newly installed rate app to your shipping profiles. Until you add Calcurates to a shipping zone, customers in that zone see no Calcurates rates.

1. In your Shopify Admin, go to Settings > Shipping and delivery.
2. Under Shipping, open the shipping profile you use. For most stores this is General shipping rates.
3. Find the shipping zone where Calcurates rates should appear and click Add rate.
4. Select Use carrier or app to calculate rates.
5. In the shipping rate list, select Calcurates.
6. Under Services, select the Calcurates shipping methods to show in this zone.
7. Click Done, then Save.

Important: Repeat these steps for every zone in every shipping profile. If a product belongs to a custom shipping profile without Calcurates, customers who order it get no Calcurates rates.

Step 4. Test your checkout

1. In Calcurates, run Test Your Rates to check how your options, methods and rates calculate. → How to check your configuration with Test Your Rates
2. On your storefront, add a product to the cart and go to checkout.
3. Enter a shipping address inside one of the zones you set up in Step 3.
4. Check that your Calcurates shipping methods appear.

Tip: To test on your live checkout without showing a method to customers, set the Shipping Option to Test mode, then enter Calcurates as the First name at checkout. Only you see Test mode options.

Troubleshooting

Calcurates doesn't appear in the Shopify rate list

• Check that CCS is enabled on your Shopify plan. → How to enable third-party shipping in Shopify
• Check that the installation finished: Calcurates should appear under Apps in your Shopify Admin.

Calcurates methods don't appear at checkout

• Calcurates is missing from the shipping zone, or from the shipping profile your product belongs to. Repeat Step 3 for that profile.
• The shipping address falls outside the zones you set up.
• The Shipping Option is disabled or in Test mode.
• A Shipping Area or Shipping Rule hides the method for that address or cart. Find the request in the Activity Feed to see which Rules applied.

Customers see duplicate shipping methods
Shopify's own flat or manual rates are still active in the same zone. Remove or disable them.
