Product Addons for Print & Sign Shops: Files, Sizes and Instant Quotes

Collect artwork, charge by the square metre and stop quoting over email — an addon setup that turns custom printing into self-service orders.

A print shop’s product page has a hard job: every order needs a file, most orders need a size, and the price depends on both. Handling that over email — “send us your artwork after checkout” — loses orders and creates support threads. Here’s an addon setup that collects everything up front, prices it live, and lands it all on the order line.

The addon setup

  • Your artworkFile Upload. Limit it to the formats your RIP can handle (pdf, png, tiff) and set a sensible size cap. Files land in a protected directory and are linked straight from the order for production.
  • Print sizeDimensions, priced by area. The customer enters width × height in cm; you charge per square metre. The math is shown as they type: 120 × 75 cm = 0.9 m² × $20.00.
  • MaterialMultiple Choice as image swatches. Vinyl, canvas, backlit film — each with its own price, shown as a picture rather than a word.
  • LaminationSingle Checkbox, flat fee or a percentage of the product price if it should scale with order size.
  • CopiesQuantity, priced per unit, for runs of the same print.
  • I have checked my artworkSingle Checkbox, required. A tiny field that prevents the most expensive mistake in the business: printing a typo.

Why it works

  • No more email ping-pong. The file, the size and the finish arrive together with the payment. The upload is required, so an order can’t exist without its artwork.
  • Quotes become self-service. By-area pricing turns “send us your dimensions for a quote” into a live total the customer calculates themselves — at midnight, without you.
  • Production reads the order, not the inbox. Every selection is order line meta: size, material, lamination, and a download link for the file, visible on the order screen and in the confirmation email.
  • Abandoned files clean themselves up. Uploads that never became an order are deleted automatically after a configurable number of days.

Build it
