How the Shipping Line Item Works in Orders

3 min read · Updated June 2026

The Shipping line item is how you attach a shipping cost to an order. Here’s what it does, how it shows up at checkout, and how it works with automatic shipping rules.

TL;DR
  • The Shipping line item assigns a shipping cost to an order.
  • With Payments on, it’s shown to the customer and added to their total.
  • You can set it manually (flat, tiered, or exact) or let automatic shipping fill it in.

What the Shipping line item is

Inside every order, Thryft Ship lets you add a Shipping line item — simply a way to assign a shipping cost to that order.

  • If you accept Thryft Ship Payments: the shipping amount can be shown to your customer at checkout and included in the total they pay.
  • If you use third-party payments: you can still add shipping to keep track of what you charged, even though the payment happens elsewhere.

How it appears at checkout

When Payments is on, the shipping amount shows as its own line on the customer’s checkout and is rolled into their total — no separate request needed.

Adding a shipping cost manually

Open the order and enter an amount in the Shipping line item before sending the checkout link. Sellers typically use it three ways:

  • Flat rate — the same shipping price on every order.
  • Tiered / per-item — a base price plus a bit more per additional item.
  • Exact — the precise label cost. You don’t have to buy the label first — use the rate estimator or click Get Rates and go back to see the cost, then enter it.

Automatic shipping settings Most sellers let Thryft Ship fill the shipping line in automatically using a saved rule — flat rate, tiered, or a free-shipping threshold. Set it once in your Accept Payments settings and it applies to new orders (you can still override any order). Full details: How the Automatic Shipping Calculation Setting Works. Local pickup orders are automatically skipped — no shipping is charged.

A couple of notes Local pickup orders don’t need a shipping charge. And whatever a rule sets, you can always override the shipping amount on a specific order before checkout.
