Frequently Asked Questions

Why can’t I see my rates at checkout?
Why does it say some items can’t be shipped?
I changed my Locations/Profiles and now my rates are broken!

We have designed our app so that you should rarely need to adjust your Shopify shipping rates once Parcelify is installed. Less pages to visit, less settings to worry about, and more time to spend growing your business!

However, occasionally these settings get changed on accident or due to edits to your store after our app is installed. If you believe any of the situations above apply to your checkout, please follow this guide: Shipping Profiles Troubleshooting

Can I use Parcelify in conjunction with another service provider?

Yes! However, please bear in mind that one cannot restrict the other from showing up rates. All rates defined within Parcelify will work independently from rates defined elsewhere.

When a client goes through checkout Shopify will request rates from all shipping rate providers you have configured and display them from least to most expensive.

Can I use this app if I don’t have Carrier-Calculated Shipping?

Not yet, and it’s not because we don’t want you to! This is a restriction imposed by Shopify.

How can I acquire Carrier-Calculated Shipping?

There are three methods to acquire Carrier-Calculated Shipping (CCS):

  1. Enroll into the Shopify Plus plan
  2. Switch to annual billing
  3. Simply contact and ask to have the Carrier-Calculated Shipping added to your shop for a monthly fee

Can Parcelify block rates from Shopify’s carrier rate providers such as USPS, FedEx, and Canada Post?

No. All rates in Parcelify will work independently from rates defined elsewhere. The opposite is also true: two shipping apps cannot interfere with one another.

Can I use distances to limit rates, such as a radius of 10km around my office?

No, Parcelify does not directly support shipping areas by distance. You can approximate this functionality by building a postcode list that represents a circular shipping area.

Can I set a custom message when there’s no rate available?

Absolutely, though this is not a feature of Parcelify. You can change your theme to give a more meaningful error to your customers when no shipping options are presented through the Shopify admin panel. You can find the text string to change by following the instructions here:

  1. Go to your Shopify Admin page
  2. Click on ⚙️ Settings
  3. Click on 🛒Cart
  4. Scroll to the very bottom of the page and click [Manage Checkout Language]
  5. Search for a line (Ctrl or Command + F in most browsers) named, “No rates for cart or destination notice”

The text you put there will display when no rates are available.

Why are my rates not updating at checkout?
Why am I getting an error message after changing my rates?

There are many possible causes for this. A common reason is Shopify will cache rates between checkouts to save time looking up new shipping options when the customer has not made any changes to their cart or address. While this feature saves time and resources on Shopify’s end, it doesn’t help when you are rapidly adjusting and checking your Parcelify shipping options.


Changing part of the address, your name, or the products in the cart will force Shopify to request new shipping rates from us. This way, you are always seeing your most up-to-date rate settings at checkout.

Does Parcelify work with discounts?

Unfortunately, Shopify calculates discounts after they have sent us the address and cart information. We have no way of calculating or filtering rates based on these discounts as we never receive them. This limitation applies to all third-party apps, not just Parcelify.

Note: this limitation only applies to 3rd party rate providers. Any rates you build directly in Shopify will be calculated after discounts as expected.

Can I use customer tags?

Currently we can not offer filtering based on customer tags. Shopify doesn’t share customer tag information when they send a rate request so there is no way for us to tell who is logged-in to your shop. Again, this limitation applies to all third-party shipping rate apps, not just Parcelify.

How often are Products and Collections synchronized?

Product information and Collections are synchronized in real time via webhooks from Shopify. This information includes:

  • SKU
  • vendor
  • Product tags

There is one scenario where real-time updates do not occur: Automatic Collections. Automatic collections are dynamic collections based on set of rules. If a Product is updated and becomes added or removed from the Automatic Collection, Shopify does not notify us of the change.

In addition to real-time updates, we do full synchronizations of our merchants’ data once every 24 hours. This daily sync includes Automatic collections.

Can I force a synchronization of Products and Collections?

Not directly. Our synchronization system has been built to always be up to date and not require manual requests to synchronize.

If you have any concerns that Parcelify is out of sync, please contact our support with information about what product you suspect is not up-to-date and we’ll check it out!

Can I use Parcelify to add Taxes/tariffs/VAT?

While it is possible to add a percentage of the order total to your shipping rates, we recommend against using this to implement taxes and tariffs. The prices we provide are included in the shipping rate amount rather than its own separate line item.

Still have questions?

We have a robust documentation that we are constantly updating and amending based on the feedback from customers like you. Please feel free to contact us if you have further questions about Parcelify.
