Shopify Delivery Customizations And Custom Order Fulfillment
Delivery customizations let you hide, rename, and reorder the delivery options customers see at checkout, but you nee...
If you sell print on demand products, Printful and Printify keep their own delivery profiles in your store. After you move to market based shipping, their rates show alongside the shipping options you create, and each market has a toggle for them. Check every market so customers are not charged twice or left without a rate.
Print on demand apps create their own delivery profile in Shopify. This profile belongs to the app. It is not something the upgrade created, and it is not something you built by hand.
You will see it in Settings, Shipping and delivery, where profiles are listed. Do not delete a profile that belongs to an app unless you plan to stop using the app.

Once your store uses market based shipping, the app rates show alongside the rates you create in each market. Each market also has a toggle that decides whether those app rates are included.
This gives you control, and it also gives you a job to do. You now decide, market by market, whether customers see the app rates, your own rates, or both.
The POD (Print on Demand) apps will add their shipping rates automatically to your Shopify shipping options.
Rates from separate shipping options can still add together at checkout. If you leave the app rates on and also add a flat rate that applies to the same products, a customer may pay both.
Test the mixed cart. It is the one that shows you the real shipping charge.
If you sell in several countries, each market has its own toggle. A market you set up last month will not necessarily match the one you set up today. Walk through every market and confirm the toggle and the options.
If a rate is missing for a destination, the cause is usually on the app side, such as a product not available for that country or a missing fulfillment provider. Contact Printful or Printify support with the product and destination. Note that their rates and fulfillment locations change over time, so I do not list any here.
The app owns its delivery profile, so its rates continue to appear. Each market has a toggle that controls whether they show.
No, not while you use the app. The profile belongs to the app, and removing it can stop its rates from working.
Rates from separate shipping options can add together. Limit your own option to products you ship yourself, and test a mixed cart.
Yes. Turn off the app rates for that market and create your own option, then price it high enough to cover what the app charges you.
Yes. Each market has its own settings, so confirm each one.
