Is ShipStation's Recommend Package Rule Enough, or Do You Need More?

Short answer: Often, yes. If you ship boxed goods and every product has accurate dimensions, ShipStation’s Recommend Package rule action will pick the box at import and build multi-package shipments without anyone opening the order. Try it first. It stops short in four places: it solves for fit rather than cost, it treats bags as rigid blocks, it counts the space inside a product as solid, and it knows nothing about temperature. If those cases are a large share of your orders, you need something that can make those decisions.

What Recommend Package does well

Recommend Package applies Packing Recommendations, ShipStation’s packing calculation. It computes a plan from your product dimensions, weights and packages, uses the fewest packages the order needs, and applies the result on every order the rule matches, including which items go in which box.

Before this existed, the choice was to write rules that guessed the box from item count, or to leave it to your packers. For many catalogues, this rule replaces both. It needs dimensions and weights on your products and a maximum weight on your packages, and it should sit above any Set Rate Shopper rule so the rate is priced against the plan.

If your orders are mostly rigid boxed goods and you’ve never tried it, that’s your next step. It costs you some catalogue work, and that work pays off whatever you do later.

Where it stops

Fit isn’t the same as cost. It finds the fewest packages that hold the order. Once dimensional weight applies, two or three smaller boxes can bill less than the plan with the fewest boxes, and it won’t choose them. Rating also happens after the box is set, so a carrier’s flat-rate box can’t win unless the order was already packed into it.

Products that give. A rectangular model treats a bag of coffee or a folded garment as a rigid block. Those orders can end up in a bigger box than your packers would use.

Products with room inside them. The inside of a bin and the space around a bottle’s neck count as solid, because ShipStation’s product record has nowhere to store that space.

Decisions that depend on outside information. A packing plan knows dimensions and weight. It doesn’t know the forecast at the destination, so it can’t decide whether an order needs an insulated box, more coolant or a faster service.

How the two compare

Decision	Recommend Package	Pro Automation
Choosing the box for a mixed order	The fewest packages that fit	The cheapest box that fits, chosen together with the rate
Dividing an order across boxes	The fewest packages	The split that costs least
Flat-rate boxes	Priced after packing	Priced side by side with your own cartons
Bags, pouches and apparel	Treated as rigid blocks	Packed as products that give
Bottles, bins and hollow products	Treated as solid	Other items can use the empty space
Perishable orders	Not considered	Decided from the forecast at the destination
Who sets it up and keeps it right	You	I do

How to tell which side you’re on

Turn the rule on for a week and compare its plans against what your packers actually do. Watch for three things:

• Packers keep overriding the plan. If they keep swapping the box for the same products, those products probably aren’t rectangles to the model.
• The plan looks right but costs too much. Check multi-box orders and anything near a dimensional weight or cubic boundary.
• The exceptions are growing. If someone keeps a list of orders the rule gets wrong, that list is the job it can’t do.

If you see little of that, you’re finished, and ShipStation’s rule is the right answer. If you need more, here are your options for automated packing.

If those cases are a meaningful share of your orders, that’s what Pro Automation is for. It’s pre-built automation that I tune to your SKUs, packaging and carrier contracts and then run for you. Your team keeps working in ShipStation, and you can run it free for 30 days on your real orders once it’s right.
