DesignFee — Design Setup Fee App

Automatically charge a design setup fee for every unique customer design uploaded at checkout. Supports flat fees, tiered pricing by quantity, and per-unit pricing — all via Shopify Cart Transform.

• Unique design detection. Customers upload their artwork and a setup fee is added automatically per unique design — not per item quantity.
• Flexible pricing rules. Choose flat fee, tiered fee by quantity, or per-unit fee. Repeat designs are charged at a discounted rate you configure.
• Seamless Shopify integration. Fees appear as real line items in checkout via Cart Transform — no theme hacks, no draft orders, works with all payment methods.
