Best Shipping Software
for Multichannel Sellers

ShipStation, Shippo, Pirate Ship, EasyShip. Four solid options with very different strengths. Here is how to figure out which one fits your business.

What multichannel sellers actually need from shipping software

Single-channel sellers just need discounted postage and a way to print labels. Multichannel sellers have a different problem. You have orders coming in from Etsy, Shopify, Amazon, eBay, or wherever else you sell. Each platform has its own order dashboard. You need a tool that pulls all of that together.

Here is what actually matters: automatic order import from every channel (so you stop logging into four dashboards every morning), carrier rate comparison so you always ship at the best price, tracking numbers pushed back to the selling platform automatically, and batch label printing so you are not clicking through one order at a time. Return labels should be easy to generate too. Everything else (automation rules, multi-user access, warehouse features) is nice to have until you hit enough volume that it becomes a necessity.

Last holiday season, a seller I know shipped 40 packages using four different seller dashboards and a mix of USPS and UPS accounts. She missed two tracking uploads, got two "item not shipped" cases, and spent three hours sorting it out. That is the problem shipping software solves. Here is how the four main options compare.

ShipStation

ShipStation is the most fully-featured shipping and fulfillment platform aimed at ecommerce sellers. It connects to 80+ platforms, supports all major carriers, and has enough automation to run complex fulfillment operations.

Pros

  • 80+ channel integrations
  • Powerful automation rules
  • Batch printing and scan-to-verify
  • Multi-warehouse support
  • Strong reporting
  • Branded tracking pages

Cons

  • Starts at $9.99/month (50 shipments)
  • Can be complex to set up initially
  • Pricing jumps quickly with volume
  • Overkill for very small sellers

Best for: Sellers shipping 100+ orders per month across multiple channels who want everything in one place and need automation to scale.

Pricing: $9.99/month (50 shipments) to $229.99/month (10,000 shipments). 30-day free trial.

Shippo

Shippo is built for simplicity. It has a free pay-as-you-go tier, solid carrier rates, and a clean interface. It also has one of the best developer APIs in the shipping space, which is why many apps are built on it.

Pros

  • Free pay-per-label plan available
  • Fast setup, minimal configuration
  • Excellent developer API
  • Good carrier rate comparisons
  • Solid returns management

Cons

  • Per-label fees add up at volume
  • Fewer channel integrations than ShipStation
  • Limited automation rules
  • No multi-warehouse support

Best for: Small sellers, developers, and businesses that ship fewer than 100 packages per month and want minimal overhead.

Pricing: Free pay-as-you-go (5 cents/label + carrier rate) or $19/month for the Professional plan.

Pirate Ship

Pirate Ship is the no-frills, no-fees option. It only supports USPS and UPS, but it offers the deepest USPS discounts available to small businesses, and it is completely free. No subscription, no per-label fees, just the carrier rate.

Pros

  • Completely free to use
  • Best available USPS rates (Cubic, etc.)
  • Simple, clean interface
  • No gimmicks or upsells
  • Batch label importing via CSV

Cons

  • USPS and UPS only (no FedEx or DHL)
  • Very limited channel integrations
  • No automation rules
  • Manual order import (CSV or manual entry)
  • Not built for multichannel order management

Best for: Sellers who primarily ship domestically via USPS and prioritize the lowest possible postage cost over platform integrations.

Pricing: Free. You only pay carrier rates, with no markup and no fees.

EasyShip

EasyShip is built around international shipping and carrier comparison. It connects to 250+ courier services worldwide, making it the strongest option for sellers who ship internationally or want access to a wider range of carrier options beyond the standard USPS/UPS/FedEx triad.

Pros

  • 250+ courier integrations
  • Strong for international shipments
  • Duty and tax calculation at checkout
  • Free plan available
  • Connects to major ecommerce platforms

Cons

  • Free plan is limited (100 shipments/month)
  • Paid plans are expensive ($29-$69+/month)
  • Interface can be overwhelming
  • Domestic-only sellers don't need most features

Best for: Sellers who ship internationally or want access to regional couriers and non-standard carriers.

Pricing: Free for up to 100 shipments/month. Paid plans start around $29/month.

Frequently asked questions

Which shipping software works with Etsy?
ShipStation, Shippo, Pirate Ship, and EasyShip all integrate with Etsy. ShipStation's integration is the deepest, automatically importing orders and pushing tracking back. Pirate Ship requires more manual steps for Etsy specifically.
Is Pirate Ship actually free, or are there hidden fees?
Pirate Ship is genuinely free. You pay only the USPS or UPS carrier rate, with no markup, no subscription, and no per-label fees. They make money through their relationship with USPS, not by charging sellers.
Does shipping software help with inventory management?
Shipping software handles the fulfillment side: labels, tracking, carrier rates. Inventory management (keeping stock levels accurate across platforms) is a separate function. For multichannel inventory sync, you need a tool like Commerce Kitty alongside your shipping software.
