Quick answer
Never compare 3PLs on pick fees alone. Compare the modeled cost of your actual order profile. Use the same SKUs, dimensions, weights, units per order, destinations, seasonality, returns, projects, and service levels in every quote.

Label platforms
Shipping software
If you pack orders yourself, the decision is shipping software rather than a 3PL. These tools buy discounted labels, sync orders and tracking with your store, and automate packing presets. Subscription prices below were checked on each vendor's pricing page on Oct 7, 2026; postage is extra.
| Tool | Pricing model | Entry point |
|---|---|---|
| ShipStation | Subscription by monthly shipments | Starter from $14.99/mo (50 shipments); own carrier accounts need Standard ($29.99+) |
| Shippo | Free tier, then subscription by label volume | Free to 30 labels; Pro from $19/mo billed monthly ($17 annual) |
| PitneyShip | 5% of label price, or flat Premium | $0 + 5% per label; Premium $34.99/mo |
| Sendcloud | Plan fee + per-label fee (EU/UK merchants only) | Free to 20 parcels; Lite €28/mo + €0.10/label |
Compare software cost at 100 to 6,000 shipments a month, including free options such as Veeqo and Pirate Ship, in ShipStation alternatives, or read Shippo vs ShipStation.
