# FunctionFlow AI

> Create Shopify Functions without coding, using AI and visual workflows.

FunctionFlow AI is a Shopify app for creating Shopify Functions without writing code. Merchants build discount, shipping, payment and checkout validation rules in a visual builder, or describe a rule in plain English and let AI draft it, then test it on a sample cart and publish it to Shopify’s checkout in one click.

## Why merchants use it

- **Build checkout rules visually:** Discounts, shipping, payment and validation Functions, all without code. A live summary tells you exactly what each rule does.
- **Describe a rule in plain English:** Type the rule the way you’d explain it to a colleague. AI picks the function type, drafts the conditions and actions, and you review it before anything goes live.
- **Test before you publish:** Run the real compiled Function against a sample cart and see why it did or didn’t apply. Then try it live in test mode, only for customers tagged ff-test.
- **Rules that know the time and your prices:** Happy hours, weekend offers and delivery cutoffs in your store’s time zone, plus discounts that skip items already on sale.

## What you can build

### Discounts

Percentage and fixed discounts, Buy X Get Y, bundles, tiered and quantity-break pricing, volume and wholesale pricing, plus happy hours and discounts that skip items already on sale.

Examples: Buy 2 get 10% off, buy 5 get 20%; Happy hour: 20% off 5–7 PM; Skip items already on sale; VIP customers get 15% off; Wholesale pricing.

### Shipping

Hide, rename or reorder delivery options, or make shipping free or discounted when your conditions match.

Examples: Free shipping above $150; Weekend free shipping; Hide same-day delivery after 2 PM; Hide express for Alaska; Local delivery by ZIP code.

### Payments

Hide, rename or reorder payment methods at checkout based on the cart, the customer or the address.

Examples: Hide COD above $300; Hide PayPal for digital goods; Bank transfer for wholesale; Hide cards for risky regions.

### Validation

Block checkout with a clear message when a cart breaks your rules: quantity limits, restricted products, blocked regions.

Examples: Max 5 units per product; Block certain ZIP codes; Block PO Box addresses; Wholesale-only products.

## Conditions

- **Cart:** Cart total, quantity, weight, distinct products, items in the cart
- **Customer:** Tags, order count, lifetime spend, logged in or guest
- **Product:** Product, variant, type, vendor, tag, collection, on sale
- **Shipping address:** Country, state, city, ZIP code, PO Box
- **Time:** Time of day and day of the week, in your store’s time zone
- **Market & custom:** Shopify Market, currency, cart attributes, line item properties

## How it works

1. **Describe or build:** Start from one of 22 templates, build with the visual When / Then editor, or describe the rule and let AI draft it.
2. **Test on a real cart:** Describe a cart, customer and address. FunctionFlow runs the compiled function, the same code Shopify runs, and shows pass or fail with a condition-by-condition “Why”.
3. **Try it in test mode:** Publish the rule for customers tagged ff-test only, and check it in your real checkout before anyone else sees it.
4. **Publish and track:** Go live for everyone in one click. Every change is versioned for instant rollback, and analytics show usage, influenced revenue and AOV lift.

## FAQ

### What are Shopify Functions?

Shopify Functions are Shopify’s official way to customize discounts, shipping, payment methods and checkout validation. They run inside Shopify’s own checkout, with no theme edits and no scripts on your storefront, and they are the modern replacement for Shopify Scripts.

### Do I need to know how to code to use FunctionFlow AI?

No. You pick conditions and actions from menus, or describe the rule in plain English and let the AI generator draft it. FunctionFlow AI compiles everything into a native Shopify Function for you.

### Does FunctionFlow AI require Shopify Plus?

No. FunctionFlow AI is a public Shopify app, so its functions work on every Shopify plan from Basic to Plus. You don’t need Shopify Plus to run custom discount, shipping, payment or validation rules through the app.

### How does the AI function generator work?

Describe the rule, for example “Hide Cash on Delivery for orders above $200”. The AI picks the function type and drafts the conditions and actions, then FunctionFlow AI validates the draft against Shopify’s limits. You review and edit it before anything is published.

### Can I test a rule before customers see it?

Yes, in two ways. The built-in tester runs the exact compiled function against a sample cart and shows what would change and why, condition by condition. Then test mode publishes the rule only for customers tagged ff-test, so you can try it in your real checkout first.

### Can a rule run only at certain times?

Yes. Add a time of day or day of the week condition for happy hours, weekend offers or same-day delivery cutoffs. Times use your store’s time zone, and overnight windows such as 10 PM to 2 AM work too.

### What if I make a mistake?

Every save is a version. Compare versions, restore an older one and publish it in one click, or switch a function off instantly with a toggle.

### How much does FunctionFlow AI cost?

Plans start at $39.99/month (Starter, 5 functions) and go up to $249.99/month (Enterprise, 50 functions and a code editor). Every plan includes a 7-day free trial and is billed through Shopify.
