Upload a print PDF you already have — business card, letterhead, badge. Mark the fields customers may edit, lock the rest, then share a link or embed it in your store. They personalize and pay; you get print-ready CMYK output. No design rebuild.

Hi Product Hunt, I'm Osi, and I build software.
Every web-to-print platform I've seen asks the shop to rebuild each design inside its own template editor before a customer can personalize anything. Most shops never do it, so they keep retyping business cards and letterheads by hand.
StackFill starts from the file you already have. Upload the press-approved PDF, click the fields customers may edit (name, title, phone, an office dropdown, a logo slot), and lock everything else. Share a hosted link or embed it in Shopify/WooCommerce. The output is print-ready: CMYK-aware, trim and bleed, PDF/X-1a with preflight — not a screenshot of a web page.
There's a free plan to try it on your own file. I'd love feedback from anyone who's run a print shop or wrangled brand templates for a team.
