Warehouse → Pack & ship. Connect EasyPost first, under Integrations.

**Connecting.** On the Integrations page, open **EasyPost** and paste an API key from your EasyPost dashboard (Account settings → API keys). A **test key** (EZTK…) buys sample labels at no charge and posts nothing to the books — use it to try the flow. A **production key** (EZAK…) buys real postage, charged to your EasyPost account. A company administrator connects it; see [Connecting Twilio, EasyPost and TaxJar with your own account](https://intubu.intuitivecapital-dai.com/docs/connect-integrations).

**How do I buy a label?**
1. Pack the order and *Close carton* with its box and weight (from the scale, or estimated from the items and box).
2. Press **Buy label** on the carton. The rates from your carriers are listed — carrier, service, days and price — cheapest first and already selected.
3. Choose one and press *Buy label*. The label opens in a new tab and the tracking number is saved on the carton, and carried onto the shipment when you ship-confirm.

A label needs the carton's weight, a complete ship-to address (street, city and postal code) on the sales order or the customer, and your company's address under Settings → Company as the ship-from.

**Print label** re-opens the label to print. **Refund** asks EasyPost to refund an unused label and reverses its postage in the books; it is available until the carton ships, after which a label counts as used. You can then buy another.

**What posts.** A real label posts its cost as a debit to **Postage & Shipping** (an expense) and a credit to **Postage Payable – EasyPost** (a liability). Both accounts are created the first time. When EasyPost charges your card, categorise that charge against Postage Payable – EasyPost to clear it.

**Without EasyPost** you type the carrier and tracking number from the carrier's own tool instead, and nothing is posted. You can also type a tracking number on a carton when EasyPost is connected.
