Features
Steps, rules, seven pricing types, layered previews and a signed checkout.
§01
Builder
Sheet 01 / 03
Everything a custom product needs, nothing it doesn’t.
Repeatable steps
Let shoppers add several charms, panels or names, each with its own options and price.
Variant mapping
Use your existing options, add your own steps on top, or mix both in one configurator.
Translations
Translate every label, option and message into your store’s languages.
Display options
Popup, side drawer or a dedicated, shareable page; progress bar, step chips and a sticky price.
Version history
Published configurators are fixed; drafts can be previewed, compared and restored.
§02
Pricing
Sheet 02 / 03
Seven ways to price, one engine everywhere.
The builder preview, the storefront and the server all run the same rules engine, so the price a shopper sees is the price they pay.
Fixed & percent
Add a flat amount or a percentage of the base price.
Per character
Price engraving by length, with or without spaces.
Per unit or area
Width × height, length or any number field, with a divisor.
Tiers
Quantity breaks or value bands.
Price tables
Look up a price from two answers — size by material, width by height.
Formulas
Safe expressions with min, max, round, ceil and if — no code runs on your store.
