What Are My Options for Automated Packing in ShipStation?

Short answer: You have five options: ShipStation’s own Recommend Package rule, a self-serve add-on, a packing API, a managed service, or a WMS. Start with the native rule, because it costs you nothing extra to try. If it falls short, the choice mostly comes down to who will set the replacement up and keep it right. An add-on needs someone on your team, an API needs a developer, and a managed service needs neither. A WMS only makes sense if your real problem is running the warehouse floor.

I run one of these options, so read this with that in mind. I’ve tried to say where each one is the right answer, including when it isn’t mine.

The options compared

Option	Best for	Setup	Where it stops
Recommend Package	Boxed goods, good data	You	Picks the box for fit, not cost. Rate Shopper runs separately, after the box is set. Treats products as rectangles
Add-on	A team with an owner for it	You	Keeping it right as your catalogue and carriers change is your job
API	Teams with developers	Developers	You build and maintain the integration
Managed service	Teams with no time	Provider	Costs more, and you depend on the provider
WMS	Labour and picking problems	Project team	A large project to take on just for box selection

ShipStation’s own rule

Recommend Package computes a packing plan at import from your product dimensions and packages, including multi-box orders. Rate Shopper then picks the rate for that box. They work independently, so the box is set before anything is priced. If you ship boxed goods and your product data is good, this may be all you need. Try it first. The catalogue work you do for it will be useful whatever you choose next.

A self-serve add-on

These are software products that connect to your ShipStation account, work out the box and write it back. Some also rate shop, and some leave rates to ShipStation, so check which you’re getting. They’re usually priced by order volume, and many offer a trial.

This is a good fit if someone on your team likes owning this kind of system and will keep it current. The trade-off is that you’ve added a piece of software to run, and it’s your job when the catalogue or the carrier contracts change.

A packing API

A packing API takes your items and boxes and returns a plan. It gives you the most control, and it’s the right choice if you have developers and something unusual to connect, such as your own order system. The packing calculation is the part you’re buying. The integration around it, and everything that happens when it breaks, stays with you.

A managed service

Here someone else tunes the automation to your operation and keeps it working. Pro Automation is this kind of option: it’s pre-built automation that I tune to your SKUs, packaging and carrier contracts and then run for you, and your team keeps working in ShipStation.

It suits a team that’s already stretched and doesn’t want to swap one problem for another. It won’t be the cheapest route, and if you have someone who enjoys running this kind of system, you may not need it.

A WMS

A WMS is the right answer to a different problem. If you’re managing labour across a building, slotting or directed picking, you may need one. If your problem is mostly which box and which carrier, it’s a large project to take on for those decisions.

What to ask before you choose

These questions separate the options quickly, and they apply to mine too.

1. Does it choose the box and the rate together, or one after the other? If the box comes first, the rate can only price what’s already been chosen. That’s where cost savings get missed.
2. How does it split a multi-box order? Ask if it chooses the split that fits or the split that costs least, and if it creates a multi-package shipment or separate orders. That second part affects tracking, slips and accounting.
3. How does it handle products that aren’t rectangles? Ask about bags, pouches, hollow bins and bottles specifically, using your own products.
4. What happens when a product has no dimensions? Some tools skip the item or the order, so find out what your team would see.
5. Who keeps it right? New SKUs, new boxes and new carrier contracts will all change the answer. Decide who does that work.
6. How does it handle perishables? If you ship with coolant, ask how it uses the forecast.
7. What happens if you stop using it? Your ShipStation account should carry on without it, so ask what would need undoing.

How I’d decide

Try the native rule first, and compare its plans against what your packers do for a week. If it’s good enough, stop there. If it isn’t, ask who on your team will own the next option. If you have that person, a self-serve add-on is worth a trial. If you have developers and unusual systems, look at an API. If nobody has the time, a managed service is the option that doesn’t add to their job.
