How Do I Send Each Print on Demand Order to the Best Print Partner Automatically?

Print on demand sellers using several print partners route orders by hand or by habit. We build routing rules by product, destination, cost and partner status.

Quick answer — TL;DR

Once you use more than one print partner, each order has a best destination depending on the product, the customer's country, the partner's cost and how backed up they are, but most shop integrations send everything to whichever partner the product was created with. We build a routing layer that picks the partner per order line by your rules, submits it, and lets you switch partners for a product or region without relisting.

Three partners, one habit

You started with one print partner. Then you added a second because their mugs were better, and a third with a production site in the US so American customers stop waiting weeks. Now an order comes in from Ohio for a T-shirt and a mug. The T-shirt is linked to your UK partner, because that is where the product was first set up, so it crosses the Atlantic. The mug goes to the mug partner. The customer gets two parcels, one of them late.

When your UK partner had a backlog before Christmas, you wanted to move T-shirt orders elsewhere for a fortnight. That meant relinking every product by hand, so you did not.

Products are tied to partners, not orders

Most print partner integrations work by creating a product in your shop that belongs to that partner. It is simple, and it locks the routing decision in at the moment you create the listing.

  • Each listing is connected to one partner's product and file.
  • The customer's country does not change where the order goes.
  • Partner costs and shipping rates change, but the routing does not.
  • A partner backlog or outage has no automatic effect.
  • Moving a product to another partner means recreating or relinking it.

So routing reflects the day you set up the product, not the order in front of you.

What fixed routing costs

Orders produced far from the customer take longer and cost more to ship, and slow deliveries mean reviews and 'where is my order' messages. Split orders ship in several parcels, often with separate shipping charges. During a partner's busy period or outage, orders sit in their queue while another partner could have printed them. The cost of switching keeps you with a partner long after it stopped being the best choice.

Margins suffer quietly as well. A partner that was cheapest when you set up may not be now.

The routing layer we build

  1. Each of your products is defined once, with the equivalent product, file and variant codes at each partner that can make it.
  2. Orders from your shop and marketplaces are received by the routing layer instead of going straight to one partner.
  3. Each line is matched against your rules: which partners can make it, which serve the customer's country, the current base cost and shipping, and whether you have paused a partner.
  4. Where one partner can make every line, your rules can prefer keeping the order together to avoid split parcels.
  5. The order is submitted to the chosen partner or partners through their APIs, with the right file for each product.
  6. Every routing decision is logged with the reason, and orders that match no rule go to a queue for a person.

The rules are yours and can be as simple as 'US to one partner, everything else to another'. The routing layer makes them apply to every order.

Routing that follows the order

The order from Ohio goes to the US partner, who makes both the T-shirt and the mug, so it ships in one parcel. When your UK partner warns of delays, you pause them for T-shirts in one click, and orders go to your second choice until you switch back. When a partner changes prices, the cost rule takes it into account.

The log shows why each order went where it did, which is useful when a customer asks why their parcel came from another country.

Signs your routing is stuck

  • Every order for a product goes to the partner it was first created with.
  • Overseas customers wait for parcels printed far away.
  • Mixed orders often ship as several parcels.
  • You did not move orders during a partner's backlog because relinking was too much work.
  • You are not sure which partner is cheapest for each product now.

FAQ

Frequently asked questions

The questions readers ask us after this guide.

Still have a question?

Ask us directly — a senior engineer will get back to you.

Ask about your project

Which partners can this route between?

Any partner with an order API, which includes the common ones such as Printful, Printify and Gelato. Partners without one can receive orders by file, with less automation.

Will my marketplace listings need to change?

Usually not. Listings stay as they are, and the routing layer receives the orders instead of each partner's own app.

Do I need matching products at each partner?

For a product to be routable, yes, each partner that may receive it needs an equivalent product and file. The file library helps with that.

What if a partner's product looks different from another's?

That is a real concern. You decide which partners are acceptable for each product, and routing never goes outside that list.

What drives the cost?

How many partners, channels and products you have, and how complex your routing rules are.
