ProShip vs ShipStation API (ShipEngine) (2026): which should you pick?

Pick ProShip if

• Fits if you are a high-volume shipper that wants rate shopping and carrier compliance handled for you
• Works for a business that already runs Manhattan Associates

Look elsewhere if

• Not for you if you are a small seller: it is sold through discovery calls and implementations
• Not for you if you want a published price: it depends on complexity, engineering and an annual maintenance agreement
• Skip it if you ship outside North America on WorldLink: other regions need Enterprise
• Not for you if you want a free plan or trial: none is listed

Pick ShipStation API (ShipEngine) if

• Fits if you are a developer adding labels and tracking to a store or platform
• Works for teams that want discounted carrier rates with no monthly fee

Look elsewhere if

• Skip it if nobody on your team writes code
• Tight if you have your own carrier contracts, as those need Advanced at $75 a month
• Pricey if you grow: $325 at 5,000 labels and $600 at 10,000
• Watch out: ShipEngine's own site now redirects to ShipStation, and Enterprise is only for 25,000+ shipments a month through sales

ProShip

• No prices are published. The vendor says WorldLink pricing depends on software complexity, engineering needs, an annual maintenance agreement and license type.
• ProShip is sold through discovery calls and implementations, so it is not a self-serve app for small sellers.
• WorldLink covers North American shipping; the vendor points shippers needing other regions to the Enterprise product.

ShipStation API (ShipEngine)

• ShipEngine's site now redirects to ShipStation, and the docs say ShipStation API was formerly ShipEngine.
• Bringing your own carrier accounts needs the Advanced plan.
• Usage over the monthly allowance is billed per extra label, or pay-as-you-go for API calls.
• Enterprise is for volumes above 25,000 shipments a month and is sold through sales.
