Embroidery + screen-print + heat-press, how do you wire that at PDP?

Three decoration methods, three different pricing curves, all modeled as Magento custom options on the product.

Embroidery is the most complex. Custom options:

• Text (free-text input, max 30 chars) + position (left chest / right chest / sleeve / back yoke) + thread color (dropdown, I load the Madeira / Isacord color palette, 200+ codes with hex previews) + font (Block / Script / Times) + size (Standard / Large).
• Logo upload (file-upload custom option, .ai / .svg / .png / .eps, max 10MB). Triggers a one-time setup fee for digitizing if first-time.
• Pricing rule: base surcharge + per-1,000-stitches addition. Most logos are 8k, 15k stitches, so the per-piece embroidery cost lands around $4, $9. Native Magento custom-option pricing + a small before_save observer that calculates stitch count from the digitizing-file metadata when available.
• Lead-time: +3 to +7 business days on top of base shipping, surfaced as a "ships in N days" badge at PDP and in the cart.

Screen-print is tier-priced by run size: 1-11 pieces, 12-47, 48+. Cheaper per piece at higher run sizes. Modeled as a separate set of custom options with a Magento Catalog Price Rule that applies the tier discount once cart qty crosses each threshold.

Heat-press (vinyl or DTF) is single-piece friendly. Flat surcharge, fastest turnaround. Smallest custom-option set: text or upload + color + position.

The PDP renders a live preview canvas (HTML5 canvas + a Magento custom-option JS hook) showing the logo on the garment before add-to-cart. Order-routing splits the line items: embroidery shop pulls the embroidery-flagged lines, screen-print shop pulls the screen-print-flagged lines, warehouse fulfills the rest. Webhook-driven from Magento order events.
