About PrntFlow
We built PrntFlow to solve the most frustrating problem in POD selling: manually uploading dozens of product mockups to Shopify. What should take minutes was taking hours.
Our Story
We're print-on-demand t-shirt sellers who've been exactly where you are.
You design mockups in Photoshop, Affinity, Canva, Photopea, or now with AI. Your POD provider generates the product variants. Then reality hits: you still need all those images in Shopify, attached to the right t-shirt product and color variant.
Shopify doesn't give you a native way to do that in bulk.
So you click through product after product, uploading mockups, selecting the matching color variant, and repeating the same steps over and over. For a catalog with hundreds of t-shirt products and multiple colors each, that quickly turns into dozens of hours of tedious, error-prone work.
The Moment We Decided to Build
CPC was rising and we needed a new mockup. Testing was easy. But then the drudgery of creating and uploading all new mockups set in. Just the thought of changing out the entire catalog was discouraging. We kept running uploads and had to reassign images because we applied it to the wrong variant. Forget about SEO and adding alt text to images. Every catalog refresh meant starting over.
We knew we weren't alone. Every POD merchant in the Shopify App Store community was facing the same bottleneck.
So we built PrntFlow - POD Mockup Uploader, a Shopify app that handles t-shirt mockups the way they should be: smart, fast, and consistent. Turn one winning mockup into a reusable template, apply it to your products, and let the app generate, upload, and assign the right image to every color variant.
Our Mission
