PackOS Labels
Discounted labels for any store. Margin on every one.
No Shopify required. No carrier contract. Connect a store, upload a CSV, or just type an address — then rate shop USPS, UPS, and FedEx, buy in batches, and see exactly what each shipment made or lost. Free account; you pay for labels.
DHL Express, DHL eCommerce and Canada Post are on the rate list too, an unused label can be voided for a carrier-confirmed refund, and the software itself costs nothing: no subscription and no markup on postage.
No subscription · fund your wallet only when you are ready to buy a label

The honest pitch
A modern label platform built around your margin
Most label tools treat shipping as a line item. PackOS Labels treats it as a P&L column. Every label is stored with the carrier, the service, the price you paid, and — when the order came in with a checkout rate attached — the margin against what your customer paid. Nothing is marked up on the way through: you pay the carrier price the screen showed you. Wallet credit is spendable on PackOS labels.
Real-time margin analytics
Every label that came in with a checkout rate is tagged with what the customer paid for shipping and what the label cost. Your shipping margin, per label — calculated automatically.
What's included
Everything you need to ship
Rate shop, buy, print, void, and analyze — all in one place.
| Discounted carrier ratesRate shop discounted USPS, UPS, FedEx, DHL Express, DHL eCommerce and Canada Post services without signing a carrier contract. Every rate is shown before you buy, so you always see the exact price. |
|---|
| Multi-carrier rate shoppingCompare rates from every connected carrier side-by-side for every shipment. Filter by cheapest, fastest, or best value. Buy the label in one click. |
| Batch label printingSelect your orders, pick rates, and print them all in one batch. 4x6 thermal, letter-size, or packing slips bundled. Prints on any thermal or desktop label printer. |
| Void and refund any labelBought the wrong label? One-click void within the carrier window. Refunds land back in your PackOS wallet automatically — no support ticket, no phone call. |
Built like a platform
Free does not mean thin
PackOS Labels is free, always — and it is still the account structure a growing shipping operation needs, not a single-user label printer.
| Teams, with rolesInvite the people who actually pack and the people who actually pay. Owner, Admin, Operations Manager, Warehouse and Viewer roles decide who can buy a label and who can see the money. |
|---|
| More than one warehouseSave every ship-from address you dispatch out of and pick the right one per shipment, instead of editing one address all day. |
| SSO for the whole accountPoint PackOS Labels at your identity provider and let people in with the login they already have. |
| Two-factor authenticationTurn on an authenticator app for any account. Buying labels moves money, so it is protected like it. |

Who we built it for
We built PackOS Labels for the shippers every Shopify-only tool ignores
You do not need a Shopify store, a carrier contract, or a developer. If any of these describe you, the free account is the whole evaluation.
- Etsy, eBay, Amazon and Faire sellers who ship their own orders
- Retailers running a mail-order line beside the shop floor
- Small 3PLs shipping for more than one client
- WooCommerce, BigCommerce and Squarespace merchants
- Shopify merchants who want more than Shopify Shipping gives them
- Anyone shipping without a store at all — one address, one box, one label
