FBA vs. WFS vs. Third-Party 3PL and How to Choose a 3PL cover the fulfillment-model decision generally. This page names two specific, commonly shortlisted options that represent the two different approaches: running shipping yourself with software, versus outsourcing fulfillment entirely.
Two different categories, not direct competitors
ShipStation and ShipBob are often mentioned in the same breath, but they solve different problems. ShipStation is shipping software — you still hold and pack your own inventory, and the tool helps you compare carrier rates, print labels, and manage orders across sales channels faster than doing it manually. ShipBob is a 3PL — you send inventory to their warehouse network, and they handle storage, picking, packing, and shipping on your behalf. Comparing them isn't "which is better" so much as "which fulfillment model do you actually want," which FBA vs. WFS vs. Third-Party 3PL covers in more depth.
Side-by-side
| Dimension | ShipStation (self-service software) | ShipBob (outsourced 3PL) |
|---|---|---|
| What you're buying | Software to manage shipping you still do yourself | A warehouse and fulfillment network that does the physical work for you |
| Where inventory lives | Your own location(s) | ShipBob's warehouse network |
| Best fit | Sellers who want to keep fulfillment in-house but need multi-carrier rate shopping and order-management efficiency | Sellers who want to stop packing and shipping boxes themselves entirely |
| Setup effort | Lower — connect sales channels and carriers, start shipping | Higher — onboard inventory into their network before fulfillment begins |
| Cost structure | Software subscription plus the carrier rates you negotiate or access through them | Storage, pick/pack, and shipping fees charged by the 3PL |
| Control over the physical process | Full — you still pack every order yourself | Limited — you're trusting their warehouse operations and quality |
How to decide
If you're not ready to hand physical fulfillment to a third party — whether for cost reasons, product-handling requirements, or simply not being at the volume where it makes sense yet — shipping software like ShipStation makes your current in-house process faster without changing who does the physical work. See How Ecommerce Shipping Rates Work for what multi-carrier rate shopping actually saves.
If packing and shipping orders yourself has become the operational bottleneck, or you want to add fulfillment locations closer to customers without renting and staffing a warehouse yourself, a 3PL like ShipBob addresses that directly — see How to Choose a 3PL for the full evaluation framework before committing inventory to any single 3PL's network.
Many growing sellers use both at different stages, or even simultaneously across channels — self-fulfilling a marketplace channel with shipping software while using a 3PL for a DTC website's order volume, for instance. See Multi-Fulfillment Strategy for how that combination actually gets managed.
Common mistakes
Comparing a self-service shipping tool's price directly against a 3PL's fees without accounting for the labor cost of packing orders yourself — the "cheaper" option on paper isn't always cheaper once your own time is counted. Signing a 3PL contract before checking their location fit for your customer base — fulfillment speed depends heavily on warehouse proximity to where your orders actually ship. Switching fulfillment models at a high-volume moment (e.g., right before a peak season) rather than during a slower period, which is when the real work of switching inventory and processes is least risky.
