Print-on-demand affiliate programs get compared far less often than pricing or product catalogs, but for a seller who also has an audience, the referral income can outpace the storefront margin itself. Most of the well-known platforms treat affiliates as an afterthought, an external network bolted on rather than something built into every account. Here is how the built-in and third-party affiliate options actually compare.
Printify and Printful are fulfillment tools first, so their referral structures typically route through general affiliate networks rather than a program built into the seller dashboard itself. Custom Ink, being a bulk quote business, has no ongoing affiliate structure at all since there is no recurring subscription to share commission from. Marketplaces like Etsy and Redbubble do not pay sellers for referring other sellers.
| Platform | Affiliate program built into every account | Commission type | Recurring or one-time |
|---|---|---|---|
| Bear Grips Pro Shops | Yes, automatic on signup | 10% of referred vendor's subscription plus $1 per unit sold | Recurring, for as long as the referral stays subscribed |
| Printify / Printful | No, external affiliate network application required | Varies by network terms | Typically one-time or limited-window bonus |
| Custom Ink | No standing affiliate program | N/A | N/A |
| Teespring/Spring | Creator-focused referral tools, not a standing affiliate program for other sellers | Varies | Varies |
Every signup, whether on the free plan or a paid VIP tier, gets a shop and an affiliate link automatically, with no separate application. The link is customizable, so updating the code also updates the referral URL. Commission is 10% of a referred vendor's subscription for as long as that vendor stays subscribed, plus a $1 bonus per unit the referred vendor sells. Payouts run bi-weekly, and all tiers, not just the top paid plan, can earn.
Gym owners, coaches, and influencers who already talk to an audience of potential vendors get the most out of a recurring affiliate structure. A gym owner who tells a fellow box owner about their Pro Shop earns on that referral's subscription every month it stays active, not just once. That compounding is the practical difference between a one-time referral bonus and a true recurring program. See the gym platform comparison for how that stacks with the storefront itself.
Before treating any affiliate program as a real income stream, confirm three things: is the commission recurring or one-time, how often is it actually paid out, and does earning it require a separate application outside the normal seller account. Programs that answer all three cleanly are rare; most print-on-demand platforms fail at least one of them.
10% of every referred vendor's subscription forever, plus $1 per unit they sell. No separate application, paid bi-weekly.
Start FreeNo. Every signup, free or paid, gets a shop and an affiliate link automatically with no separate application.
Ongoing. It is 10% of a referred vendor's subscription for as long as they stay subscribed, plus $1 per unit that vendor sells.
Their referral structures typically run through external affiliate networks with terms set by that network, which commonly lean toward one-time or limited-window bonuses rather than a recurring share.
