This looks like a geography filter and it is really one problem with two halves, both created by cash on delivery. Shopify treats it as a manual payment method, listing cash on delivery alongside money orders and bank transfers, and an order placed that way sits marked as unpaid until you say otherwise. Nothing is verified when it is placed. So half of this category exists to confirm the order before anything ships, by automated call or text, and half exists to book the shipment with a local courier once it is confirmed.

The courier half runs into a specific gap. Shopify builds a tracking link automatically only when the fulfillment names a carrier it recognizes, and its list is country-specific: it covers Indian carriers by name and none of Pakistan's, so an app has to supply the tracking URL itself for a customer to get a working link. Shopify's own label buying is a separate service whose eligibility varies by carrier and country, which is why every listing here is a booking integration against an account you hold rather than a way to buy postage inside Shopify.

What to look for in a Post Ex app

Confirmation before dispatch: If a meaningful share of your cash-on-delivery orders never get accepted at the door, this is where the money is. Look at what happens to an unanswered call: how many attempts, whether it falls back to a text, and whether the outcome is written onto the order as a tag your fulfillment process can filter on.
Your courier, by name: These are individual carrier integrations, not a generic shipping layer. Match the app to the account you actually hold, and check whether it books, prints and tracks or only does one of the three.
What the customer can follow: Since Shopify will not resolve the tracking link for these carriers on its own, the app has to supply it. Confirm that the number lands on the order with a working URL, and see what the tracking page looks like before you point customers at it.
Catching the order you should not ship: Duplicate orders, addresses that cannot be delivered to and repeat refusers are the recurring loss here, and several listings on both sides of this category address them. Treat that as a feature to compare rather than a bonus.

What does the Built for Shopify badge mean?

Built for Shopify
Built for Shopify is the highest level of recognition Shopify awards an app. To earn the badge, an app must meet Shopify's standards for safety, performance, ease of use, and proven usefulness: it cannot slow down the admin, storefront, or checkout, must integrate seamlessly into the Shopify admin, and must demonstrate quality through installs, reviews, and ratings over time. When comparing similar apps, preferring ones with the badge is a safe default. Learn more about the Built for Shopify badge →
