DropMindYour customer ordered two things. The supplier sent two parcels. The marketplace is waiting for one number.
Nobody warns you about this until the first split order. Two items, two print providers, two parcels, two tracking numbers — and a marketplace order that was built to hold one.
A customer buys two things from you in one go. Good day. Then the supplier ships them as two parcels, from two places, on two different days, with two tracking numbers — and your marketplace order sits there waiting for a single one.
This isn't a malfunction. It is how print-on-demand fulfilment is built, and both of the big providers describe it in their own help pages.
Why one order becomes two parcels
Printful: «Not always. Some items are packaged separately to keep them safe and in good shape during shipping. Others might be sent from different fulfillment centers, so they'll arrive in separate packages».
Printify is even more direct, because on Printify the products in your shop can come from different companies entirely: «If an order consists of items from multiple Print Providers, there will be multiple shipments with separate tracking numbers».
That second one is worth sitting with. On Printify the print provider is chosen per product, so a T-shirt and a mug in the same order may be made by two unrelated businesses in two countries. There is no warehouse where the two ever meet before reaching your customer.
The sentence that causes the real damage
It comes right after, in the same Printify paragraph, and it is the one nobody quotes: «Please be aware that some shipments might use untracked carrier services, depending on the Print Provider».
Untracked. Not «tracking that updates slowly» — no tracking number at all for that parcel. And you find out which orders those are after they have shipped, not when you choose the product.
Now put that next to how a marketplace decides you were late. eBay considers an item late when two things are both true: the delivery scan happens after the last estimated date, and there is no carrier scan within your handling time. A parcel with no tracking can never produce a carrier scan — so on that half of the order, the second condition is permanently true.
What this does to your numbers
Three things, and they compound.
- You pay shipping twice. Printful says it plainly for the categories that always travel alone: «We recommend calculating the shipping fees for the product categories mentioned here assuming that they would always ship separately.» The second-item discount you were counting on does not apply when the second item leaves from somewhere else.
- Your customer thinks half the order is missing. They get one parcel and one notification. Nobody told them it was coming in two, because you didn't know either at the time of sale.
- The support message arrives before the second parcel does. And it arrives on the marketplace, where the clock is already running on your response time.
None of these is dramatic on its own. Together they turn a two-item order — the one you wanted, the one with the better margin — into the order most likely to generate a complaint.
What can actually be done
Not much about the splitting itself: that belongs to the supplier's network. What you can change is everything around it.
- Check which provider makes each product before you publish it. On Printify this is a choice, not a fact. Two products from the same provider ship together; two from different providers never will.
- Price shipping as if every item travels alone. It is the supplier's own recommendation for the categories that always do, and it is the safe assumption for the rest.
- Tell the buyer, in the listing, that a multi-item order may arrive in more than one parcel. It costs a line of text and removes the most common message you will otherwise receive.
- Build bundles from products made in the same place. If you are going to push people to buy two things, push them towards two things that can share a box.
- Treat the untracked shipments as the risky ones. They are the orders where you have no evidence of anything, on a platform that decides lateness by scans.
One thing we are not going to tell you is how to handle two tracking numbers inside a marketplace order that expects one. Whether their interface allows it, and what happens if you enter one and not the other, is a question for that platform's own help pages — and «just upload one of them» is the kind of advice that turns a shipping problem into an account problem.
Where DropMind fits
It doesn't decide how your supplier packs parcels, and it can't merge two shipments into one.
Where it helps is the part that comes before: knowing what you are publishing and at what real cost, across suppliers, so that a bundle you build on purpose isn't secretly two orders wearing one price. That check is the whole difference here, and it happens at publishing time — not when the parcels are already moving.
You can try DropMind for seven days before paying anything. Same software, no cut-down version.

From the Printful and Printify help centres and from eBay's seller performance page, opened on 3 and 4 September 2026. The eBay sentence is quoted in Italian in our companion article on printing times, because that is the language eBay publishes it in.
What this article does not cover, deliberately: how each marketplace handles more than one tracking number on a single order. We have not verified eBay's, Etsy's or Amazon's behaviour on that, and guessing would be worse than useless — the answer decides whether half your order counts as shipped.
