What the action buys and what you set
Shopify's changelog announced the Purchase shipping label action on October 15, 2026. It runs after a trigger that carries a fulfillment order, such as Fulfillment order ready to fulfill, and each run buys one label for one order fulfillment, ready to print from your Shipping labels page. You set four fields:
- Shipping service — per Shopify's help, the cheapest available, or one fixed service.
- Saved package — per Shopify's help, one you choose, or the recommended package if unset.
- Total weight — the line items' assigned weights, or one custom weight.
- Send shipping confirmation to buyer — the date that notification is sent.
- Apps
- Flow
Bulk buying — looping through a list of order fulfillments — needs a For each loop, and its list can't have more than 1,000 items; past that, the workflow fails and no action after the loop runs.
Which orders does the action skip?
Conditions pick which orders reach the purchase step: a tag, certain products, single-item orders or any combination of order attributes. Orders that don't match are left alone.
Available carriers and services depend on package weight, order destination and your fulfillment locations; label eligibility itself is covered in why you can't buy a shipping label on Shopify.
How Flow and Shopify Shipping labels are billed
Flow itself is free: as of October 2026 Shopify calls it “a free app available on the Basic, Grow, Advanced, and Plus plans,” installed from the Shopify App Store.
The action buys its label through your Shopify admin. Shopify Shipping labels bought in your Shopify admin are billed to the credit card on file for your Shopify account, with invoices based on threshold billing.
