What is the best free shipping software?
Pirate Ship is the only platform on this list that is genuinely free forever — no monthly fee, no per-label fee. It is US-only and limited to USPS and UPS, but for US-domestic small sellers it is mathematically the cheapest way to print a label. Shippo's Starter tier (30 labels/month) and ShipStation's Free Plan (10 shipments/month) are the best multi-carrier free options.
What is the best shipping software for international shipping?
If you ship cross-border and need duty and tax calculated or displayed at checkout, Easyship is the closest fit — calculation is on the Free tier and display-at-checkout is gated to Premier and above. ShipStation has the deepest carrier ecosystem (200+) and explicit US/UK/AU/Canada presence. For UK and EU outbound, Sendcloud's pre-negotiated Royal Mail, Evri, InPost UK and DPD UK rates make it the strongest regional option.
Does shipping software calculate duties and taxes?
Most do not. Of the seven platforms on this list, only Easyship advertises automatic duty and tax calculation as a core product feature, with checkout display gated to Premier. Shippo, ShipStation, Pirate Ship, Sendcloud and Starshipit do not offer landed-cost calculation in their software. If you only need to estimate duty before shipping, a free landed-cost calculator is usually a better pairing than upgrading a shipping plan.
What's the best shipping software in the UK?
Sendcloud is the UK and EU specialist — 170+ couriers with named UK rates from Royal Mail (£2.22), Evri (£2.49), InPost UK (£2.49) and DPD UK (£4.99). ShipStation has a UK presence with a localised site. Shippo and Easyship both ship to and from the UK with named UK carriers.
What's the best shipping software in Australia?
Starshipit is AU and NZ-anchored, with explicit Australia Post and NZ Post integrations and a 60+ courier roster. Its pricing model is bring-your-own-carrier-rates with no per-label markup, which suits AU sellers with negotiated Australia Post contracts. Shippo also supports Australia Post and Sendle for AU sellers; Easyship works in AU but doesn't surface Sendle as a carrier.
Should I use a 3PL or shipping software?
They solve different problems. Shipping software (Shippo, ShipStation, Easyship, Pirate Ship, Sendcloud, Starshipit) helps you buy and print labels for orders you fulfil yourself. A 3PL (ShipBob) takes inventory into its own warehouses and ships orders for you. Most growing brands use shipping software up to a volume tipping point, then hand fulfilment to a 3PL once warehousing becomes a bottleneck.
ShipStation vs Shippo — which is better?
ShipStation has more integrations (400+ partners), more carriers (200+), and stronger automation rules — best for sellers running multiple stores or marketplaces. Shippo is simpler, has a better entry-level free tier (30 labels/month vs 10), and Pro starts at $17/month vs ShipStation Starter at $20/month. Pick ShipStation for multi-channel scale; pick Shippo for simplicity and price.
Is Pirate Ship really free?
Yes. Pirate Ship has no monthly fees, no per-label fees, and no payment fees — it earns commission from USPS and UPS rather than from users. It is US-only and supports two carriers, which keeps the model viable. For US-domestic USPS-heavy sellers it is the cheapest path to a label.
Does shipping software work with Shopify, Etsy or Amazon?
All seven platforms on this list integrate with Shopify and most major marketplaces. Shippo and ShipStation have the broadest direct integrations (eBay, Etsy, Amazon, Walmart, BigCommerce, WooCommerce). Shopify Shipping is built into Shopify itself but locks you into one channel; the platforms here let you ship from multiple channels in one tool.
How do I pick between these seven platforms?
Start from your bottleneck, not the feature list. If labels are too expensive: Pirate Ship (US) or Shippo Starter. If you ship across many stores: ShipStation. If buyers in foreign markets keep getting surprise customs bills: Easyship. If your warehouse is full: ShipBob. If you sell mostly in the UK or EU: Sendcloud. If you sell in AU or NZ: Starshipit.
