The problem

Made-to-measure does not fit in a variant.

The catalog fills up

Every width, fabric and lining becomes another variant. Managing the product takes longer than selling it.

The quote goes cold

A shopper who has to wait for a price buys somewhere else. A live total checks out now.

The price can be edited

A number that only exists in the browser can be changed before checkout closes.

How it works

From a plain product page to a price that holds.

01

Install the app

From the Shopify App Store. A free plan lets you try it on a real product.

02

Build the calculator

Drag the fields into place and write the formula. Or let AI draft both from one sentence.

03

The shopper checks out

Size, colour and add-ons sit on the product page. The total is the one that reaches the cart.

Builder

Assembled without code.

Text, number, dropdown, swatch, date and upload. AI drafts the options and a formula from a description of the product.

  • Drag in as many fields as you need
  • AI proposes the options and the pricing formula
  • Styling follows the theme

Formulas

The price follows the size.

Width times drop, a price per square metre, a tier, or a table. Product metafields can sit inside the formula.

  • Formulas, variables and metafields
  • Lookup tables for width × drop
  • The total updates as the shopper chooses

Options

A swatch swaps the product photo.

Swatches, radios and dropdowns can carry their own image. The gallery follows the fabric the shopper picks.

  • An image on each choice
  • Combined with dimensions and add-ons
  • A price attached to every option

Preview

Type, a font and a file, on the product.

The shopper sees the personalisation on the photo and hands over a file. That file stays with the order.

  • Font and colour on the product photo
  • Upload for a print, a sticker or a drawing
  • Personalise without extra variants

Secure pricing

The formula beats the browser.

Turn on server-side validation. Before checkout the server recalculates with your formula and corrects a price that does not match.

  • A check on every calculated product
  • Optional, server-side, using your formula
  • The price and the formula cannot be edited in the browser

Great application that fills all our needs for a custom embroidery studio, where customers can select how many logos to add and where to place them on garments, and get the final price immediately. Easy to build the calculator and configure formulas. Also, great and helpful support!

Questions

Before you install.

Do I create a variant for every size?

No. Sizes, fabrics and surcharges are options on the product. The variant catalog stays small.

Can a shopper change the price in the browser?

With server-side validation on, the server recalculates with your formula and corrects a mismatched amount before checkout.

Which products is this for?

Anything priced by size, quantity or a choice. Curtains, furniture, stickers, print, glass, gifts with a line of text.

What is on the free plan?

The listing describes it as the Ultimate plan, free, with a 20-use limit. After that you pick Starter, Premium or Ultimate.

Can the product page be in more than one language?

Multilingual options are part of Starter. You write the labels per language.

Can you set the calculator up for us?

Ultimate includes a free setup. There is also an AI setup, and the documentation is available if you want to do it yourself. You can also hire Online Origins, the studio behind the app.

Start selling made-to-measure on Shopify.

Installation happens on the Shopify App Store. If you want the formula built for you, that is included on Ultimate, or you can bring in Online Origins.
