Appify Custom Product Options for Shopify

Advanced Pricing, Product Design, and Print-Ready Output

Create calculators where options drive price, preview, design, proofing, and print-ready files — all before checkout.

  • Full-screen design studio — customers add text, clipart, shapes, and images on a real artboard, then save before add to cart.
  • Built-in photo editor — crop, filter, enhance, annotate, and swap backgrounds on uploaded photos — no separate app.
  • Calculator-driven canvas — size, material, pattern, and finish options update the design live through canvas bindings.
  • Production-ready output — proof PNG, print-ready PNG with bleed, cut-line SVG, canvas JSON, and a production manifest.
  • International-ready — fully translatable editor UI, same multi-language workflow as the rest of your calculator.

Complex Shopify pricing without being technical

Built for serious Shopify pricing:

AI clears the cliff — setup, formulas, tables, structure, styling, translations & more —

Pro-level power, fewer dead ends, faster launches.

  • Pricing engine that goes past “simple options” — formulas, 50+ functions, 1D/2D pricing tables, quantity rules (1D/2D), fees, and conditional adjustments.
  • Customer-friendly configurators — multi-step flows, show/hide logic, limits, and validation so big products don’t feel impossible to buy.
  • Transparent totals — optional price summary so shoppers see how the number was built (not a black-box total).
  • International-ready — translations and Shopify Markets currency so the same calculator can travel with your business.
  • AI on the painful parts — calculator build, formula writing, styling, and translation gaps—while you still ship a calculator that matches your rules.

Formula Engine

Stop hitting limits when your pricing logic gets too complex for basic calculator apps.

  • Write formulas for simple or complex pricing.

  • Combine product data, options, customer inputs, and variables in one formula.

  • Set pricing by size, quantity, date-related choices, and other conditions.

  • Use the same formula logic for totals, fees, and adjustments.
 Try Appify Custom Product Options

50+ Built-In Functions

Math, logic, lookups, and rounding in one formula — match how you really price, with less syntax to memorize.

DATA INPUTS

Use customer choices, measurements, variables, and table lookups in your formulas.

Logic & Math

Use IF, AND/OR, comparisons, min/max, powers, and roots in the same formula.

Safe Numbers

Round, clamp, cap ranges, and divide safely so edge cases don’t break pricing.

Text & Strings

LEN, CONCAT, character counts for text-based pricing.

6 ready to use, fully customizable template

Start from a polished look, then tune colors, spacing, and type with simple controls—without fighting your theme.

Version Control & History

Stop live editing — Work in draft — publish when ready — restore anytime

  • Edit in draft—shoppers stay on the last publish until you publish the new version.

  • Every publish saves a new version — so you always have a trail of what went live.

  • Save checkpoints (with notes) before big changes—no publish required.

  • Restore any older version—load it as draft, preview, then publish when it’s right.

  • Pin key versions so important releases are easy to find.

  • Go not-live to hide the calculator while you fix things—without losing your work.

Pricing Variables

Split complex pricing into clear, reusable pieces.

  • Replace giant formulas with a short list of building blocks, each doing a single clear job.

  • Reuse the same calculated value for totals, fees, adjustments, and options —without copying the same math everywhere.

  • Change one block when rules shift instead of untangling a long formula in multiple places.

Pricing Tables

Keep rate sheets and price grids separate from your formulas—then look up the right price in one step.

  • Use 1D tables for simple lookups (one key → one value, like material or size band).

  • Use 2D tables for grids (two keys → one value, like width × height or qty band × option).

  • Choose how lookups match — exact match, nearest key, or interpolation for numeric ranges.

  • Share one table across calculators when the same rates apply to many products, or keep a table local to one calculator when it does not.

Calculator, summary, and tiers — your layout, your theme

Three theme blocks—calculator, summary, tiers—drag to arrange, tweak width and spacing in block settings. No code; fits beside your existing sections.
  • Place three dedicated blocks—calculator, price summary, and quantity tiers—and arrange them like any other theme blocks (stacked, side-by-side, or across sections, depending on your theme).

  • Dial in layout from block settings—for example summary beside the calculator (above, below, left, or right), spacing, and width where the calculator block exposes those controls.

  • Go full width or narrow columns by how you add the section and blocks—same workflow merchants already use for the rest of the page.

  • Ship without developers—everything is configured in the Theme Customizer; no HTML/CSS required for standard layout.

2D Quantity Discounts

When discount depends on quantity and something else — (area, width, or weight)

  • Use different quantity breaks for different sizes or ranges — so a big configuration doesn’t share the same discounts as a small one.

  • Avoid one-size-fits-all volume rules that would over-discount hard jobs or under-discount easy ones.

1D Quantity Discounts

Simple volume pricing: better price when customers buy more.

  • Set quantity thresholds and what happens at each one (percent off, dollars off, or target price per unit).

  • Control how quantities combine in the cart — per line, per product, or same calculator.

  • Apply discounts automatically at in cart and at checkout (no discount codes).

Fixed fees

Add extra charges on top of the calculated product price — setup, handling, rush, or anything else you need to bill separately.

  • Add one or more named fees with either a flat amount or a formula so the fee only applies when your rules say so.

  • Show each fee as its own line in the price summary so customers see what they’re paying for.

  • Keep fees out of product discounts—quantity discounts and calculator discounts apply to the product price, not to fees.

  • Hide a fee automatically when its formula works out to zero, so customers only see charges that actually apply.

  • Convert prices automatically when your store sells in more than one currency.

  • Keep options, fees, and the breakdown in sync so everything matches the same currency.

  • Use Shopify for rates and regional pricing—you set it up once in Shopify, not again inside the calculator.

Conditional visibility

Show the right fields at the right time with advanced visibility options that can also set min, max and required fields.

  • Limit allowed values (ranges, max selections, allowed choices, text length, date windows) when conditions match.

  • Show or hide whole options based on what was selected or entered elsewhere.

  • Hide or reveal specific choice values for dropdowns, radios, swatches, and similar controls.

  • Require fields only when relevant dynamically instead of making customers guess what’s mandatory.

  • Change content blocks based on other options - dynamically swap help text, notes or any html content when options change

Price adjustments

Add conditional price changes when specific selections or measurements apply — without turning your main formula into a wall of IF statements.

  • Create rules that only run when conditions match (for example material, size limits, rush toggles, or numeric ranges).

  • Set the change with a formula—flat amount, percentage-style math, or anything your pricing needs.

  • Combine conditions with ALL / ANY logic so the rule fires exactly when you intend.

  • Stack and reorder multiple adjustments so complex pricing stays organized and predictable.

Multi-step Layouts

Turn a long calculator into short pages customers step through — instead of one endless form.

  • Switch between a single page and multiple steps for the same calculator.

  • Name each step with a title and optional description so the flow is obvious.

  • Assign options to steps so related choices stay together (for example size first, then material, then add-ons).

  • Reorder or remove steps as your product changes, without rebuilding the whole calculator.

Build Calculators with AI

Describe what you sell in plain English and get a full starter calculator—options, pricing, and layout.

  • Generate an initial calculator from a product description instead of building from a blank page.

  • Refine with follow-up messages (for example “add a rush option” or “split steps”) before you move to manual editing.

  • Edit everything afterward in the normal editor—nothing is locked in by AI.

More capabilities

These are additional features beyond the main highlights—useful for teams who need deeper pricing, fulfillment, integrations, and scale.

Pricing & catalog logic

    Calculator-level discounts

    Rule-based discounts applied to the calculated subtotal, separate from quantity tier discounts—useful for promotions and reductions driven by calculator logic.

    Product & variant data in formulas

    Use live Shopify product/variant context inside formulas (like price and quantity), plus metafield-backed values when configured—so pricing can follow real catalog data without duplicating it in the calculator.

    Custom SKU rules

    Build SKUs from a composition template and per-choice SKU fragments so each configuration generates a consistent code. Optional display in cart for fulfillment and systems integration.

    Weight calculation (shipping weight)

    Compute shipping weight from customer selections using the same formula approach as pricing, with explicit units—so carriers and shipping apps see realistic weights.

    Tax handling (optional)

    Optional tax-related configuration so tax presentation can align with how you sell—especially relevant when display expectations matter for your market.

Storefront & integration

    Theme app extension + app embed

    Deliver calculators through Shopify theme blocks with a required app embed activation—this is the standard, low-code integration path across compatible themes.

    Checkout pricing enforcement

    Helps ensure customers are charged the calculator-computed amount through checkout—not just a storefront estimate—so pricing stays trustworthy end-to-end.

    Automatic discounts integration

    Supports calculator-driven discounting without relying on customers entering discount codes—especially important when cart quantities change and discounts must remain correct.

    Configuration saved on the line item

    Customer selections travel with the cart line so fulfillment can see exactly what was configured alongside the charged price.

Builder depth (advanced UX & control)

    30+ option types

    Broad input library including measurements (length, area, volume, weight, dimensions), sliders, date/time pickers, color/font pickers, file uploads, switches, multi-select patterns, and display blocks (content, headings, dividers, spacers, modals, inline calculation readouts).

    Min / max constraints

    Validation guardrails like numeric bounds, step increments, text length limits, and similar controls to block invalid configurations before add to cart.

    Value rules (auto-fill)

    Automatically set or adjust values based on other selections to reduce effort and prevent invalid combinations—pairs well with visibility rules for guided configurators.

    Swatch carousel paging

    Paginate large swatch sets into carousel pages with navigation controls so big finish libraries stay usable.

    Large image hover preview (image swatches)

    Show a larger preview on hover for finishes/materials where thumbnail clarity drives decisions.

    RTL support

    Right-to-left layout support for RTL locales when enabled.

    Calculator-level JavaScript

    Optional global script hook for advanced customization beyond formulas and theme styling.

    Option-level JavaScript

    Optional per-field scripting for advanced behaviors where formulas alone aren’t enough.

    Storefront JavaScript API

    Read live calculator state from documented events and set values programmatically from theme or partner code—useful for custom UX and integrations.

Operations, scale, and editor workflow

    Unlimited calculators

    Create as many calculators as you need for different product lines, experiments, and seasonal flows.

    Draft / saved / published + live preview

    Iterate safely with preview against real products and variants before changes go live on the storefront.

    Versioning / checkpoints

    Rollback-friendly history for configuration changes—especially valuable for teams editing pricing logic.

    Publishing workflow

    Explicit publish controls so storefront behavior doesn’t change accidentally while you’re still editing.

AI-adjacent

    AI pricing generation (broader setup assistance)

    Beyond single-field formula help, AI can assist with drafting broader pricing structure (like variables and tables)—useful as a faster starting point for complex catalogs.
