Carriers & packaging

Settings → Carriers & packaging (/settings/carriers) holds the three things that turn a picked order into a parcel somebody collects.

Carrier accounts

A carrier account is what turns a packed parcel into a bought label. Connect the accounts you actually ship with; Shipping then shows every rate across all of them, sorted by price and speed.

Freight carriers are configured here too — a ShipEngine LTL account for less-than-truckload, or Uber Freight for full-truckload. Uber Freight is apply-gated: request access first.

Try it with the test carrier

No carrier connected yet? Choose Use the test carrier — here, on the empty shipments list, or at the pack bench when a label cannot be bought. It is built in: nothing to sign up for, nothing to type.

• Its one service, Test label, costs 0.
• Its label is a real PDF you can print and reprint: the ship-to, the order, a TEST-… number, and in its largest type TEST LABEL: NOT VALID FOR SHIPPING. Voiding it only marks it void.
• A parcel fulfilled with a test label is fulfilled in Shopify without tracking, even if a number is typed in, and no shipping confirmation goes to the customer — not from Shopify, not from Floormode. Webhooks and Shopify Flow hear nothing of a test label. Trying it on a real order never e-mails a tracking link that leads nowhere.

Caution

The test carrier never ships anything. Connecting a real carrier turns it off, so a test draft left over is never bought by itself. Turn it on again to make another test label: the real carrier stays the default, and no checkout option or shipping rule can choose the test carrier.

Label printers

Label printing goes through PrintNode. With it connected, a bought label goes straight to the station printer; a picker never touches a file dialog.

Note

A printer is optional. Without one you download the label as a PDF and print it by hand — slower, but complete. Packaging, carrier and printer are not setup steps; they are one link away on the You’re live screen and under Settings.

Bin label printing from the Bins tab uses the same connection.

The box catalog

The box catalog is the set of packaging you actually own — each with its dimensions and, where relevant, its cost.

CartonizationCartonizationChoosing the cheapest suitable box for an order from your box catalog, using item dimensions — and splitting into several boxes where one will not do. Read more → at the pack step chooses from this catalog: the cheapest suitable box for the items being packed, split across several where one will not do.

Two things make it work well:

1. A complete catalog. A box you use but never entered cannot be chosen.
2. Item dimensions on your products — see Item dimensions & capacity.

Without any boxes at all, nothing can be cartonized, which is why adding your boxes comes right after going live.
