## 1. Loading States
**Impact: CRITICAL**
The pricing model loads asynchronously. Rendering before data is available causes visual flicker, incorrect UI states, or hydration mismatches.
### 1.1 Wait for pricingModel Before Rendering
**Impact: CRITICAL (prevents flash of incorrect content)**
Always check that billing data has loaded before rendering pricing UI. The `pricingModel` is `null` or `undefined` until the billing data loads.
**Incorrect: renders empty or broken UI while loading**
```tsx
function PricingPage() {
const billing = useBilling()
// BUG: pricingModel is undefined while loading!
// This renders empty pricing grid, then re-renders when data arrives
const products = billing.pricingModel?.products ?? []
return (
{products.map((product) => (
))}
)
}
```
Users see an empty pricing page that suddenly fills in, causing layout shift and poor UX.
**Correct: show loading state until data is ready**
```tsx
function PricingPage() {
const billing = useBilling()
// Wait for billing to load
if (!billing.loaded) {
return
}
// Handle error state
if (billing.errors) {
return
Unable to load pricing. Please try again.
}
// Now safe to access pricingModel
const products = billing.pricingModel?.products ?? []
return (
{products.map((product) => (
))}
)
}
```
**Alternative: early return pattern**
```tsx
function PricingPage() {
const billing = useBilling()
if (!billing.loaded || billing.errors || !billing.pricingModel) {
return
}
// TypeScript now knows pricingModel is defined
const { products } = billing.pricingModel
return (
{products.map((product) => (
))}
)
}
```
### 1.2 Public Pricing Pages with usePricingModel
**Impact: CRITICAL (enables unauthenticated pricing pages)**
For public pricing pages that don't require authentication, use the `usePricingModel()` hook instead of `useBilling()`. This returns only the pricing data without requiring a logged-in user.
**Incorrect: uses useBilling for public page**
```tsx
// Public pricing page - no user logged in
function PublicPricingPage() {
// BUG: useBilling requires authentication context
// Will fail or return empty data for unauthenticated users
const billing = useBilling()
if (!billing.loaded) return
Loading...
return
}
```
**Correct: uses usePricingModel for public pages**
```tsx
import { usePricingModel } from '@flowglad/nextjs'
function PublicPricingPage() {
// Works without authentication
const pricingModel = usePricingModel()
// Returns null while loading
if (!pricingModel) {
return
}
return (
)
}
```
**When to use each hook:**
- `useBilling()` - Authenticated pages where you need subscription status, checkout, or user-specific data
- `usePricingModel()` - Public pricing pages, marketing sites, or anywhere you just need to display plans
---
## 2. Accessing Pricing Data
**Impact: HIGH**
Flowglad provides helper functions to access products and prices by slug. Using these helpers is more reliable than manual array lookups.
### 2.1 Use getProduct and getPrice Helpers
**Impact: HIGH (prevents runtime errors, cleaner code)**
The billing object provides `getProduct()` and `getPrice()` helper functions that look up items by slug. Use these instead of manually searching arrays.
**Incorrect: manual array lookup**
```tsx
function UpgradeButton({ targetPriceSlug }: { targetPriceSlug: string }) {
const billing = useBilling()
if (!billing.loaded) return null
// Fragile: searches across all products, easy to get wrong
const targetPrice = billing.pricingModel?.products
.flatMap((p) => p.prices)
.find((price) => price.slug === targetPriceSlug)
if (!targetPrice) return null
return
}
```
**Correct: use getPrice helper**
```tsx
function UpgradeButton({ targetPriceSlug }: { targetPriceSlug: string }) {
const billing = useBilling()
if (!billing.loaded) return null
// Clean: helper does the lookup efficiently
const targetPrice = billing.getPrice(targetPriceSlug)
if (!targetPrice) return null
return
}
```
**Same pattern for products:**
```tsx
function ProductFeatures({ productSlug }: { productSlug: string }) {
const billing = useBilling()
if (!billing.loaded) return null
// Use getProduct helper
const product = billing.getProduct(productSlug)
if (!product) return null
return (
{product.features.map((feature) => (
{feature.name}
))}
)
}
```
### 2.2 Filter Products for Display
**Impact: HIGH (shows only relevant products)**
Not all products should appear on pricing pages. Filter out default/free products and products without active prices.
**Incorrect: displays all products including internal ones**
```tsx
function PricingGrid() {
const billing = useBilling()
if (!billing.loaded || !billing.pricingModel) return null
// BUG: Shows ALL products, including free tier and inactive products
return (
)
}
```
**Correct: filter to displayable products**
```tsx
function PricingGrid() {
const billing = useBilling()
if (!billing.loaded || !billing.pricingModel) return null
// Filter products for display
const displayProducts = billing.pricingModel.products.filter((product) => {
// Skip default/free tier products
if (product.default === true) return false
// Only show products with active subscription prices
const hasActivePrice = product.prices.some(
(price) => price.type === 'subscription' && price.active === true
)
return hasActivePrice
})
return (
{displayProducts.map((product) => (
))}
)
}
```
**Transform to UI-friendly format:**
```tsx
interface PricingPlan {
name: string
description?: string
displayPrice: string
slug: string
features: string[]
unitPrice: number
}
function transformProductsToPricingPlans(
pricingModel: PricingModel | null | undefined
): PricingPlan[] {
if (!pricingModel?.products) return []
return pricingModel.products
.filter((product) => {
if (product.default === true) return false
return product.prices.some(
(p) => p.type === 'subscription' && p.active === true
)
})
.map((product) => {
const price = product.prices.find(
(p) => p.type === 'subscription' && p.active === true
)
if (!price?.slug) return null
return {
name: product.name,
description: product.description,
displayPrice: `$${(price.unitPrice / 100).toFixed(2)}`,
slug: price.slug,
features: product.features.map((f) => f.name).filter(Boolean),
unitPrice: price.unitPrice,
}
})
.filter((plan): plan is PricingPlan => plan !== null)
.sort((a, b) => a.unitPrice - b.unitPrice)
}
```

## 3. Building Pricing Cards
**Impact: MEDIUM**
Pricing cards display product information with proper formatting. Getting price formatting and interval display right is essential for clear communication.
### 3.1 Format Prices from Cents
**Impact: MEDIUM (prevents displaying wrong amounts)**
Flowglad stores prices in cents (e.g., 1000 = $10.00). Always convert to dollars for display.
**Incorrect: displays cents as dollars**
```tsx
function PriceDisplay({ price }: { price: Price }) {
// BUG: Shows "$1000" instead of "$10.00"
return ${price.unitPrice}
}
```
**Correct: convert cents to dollars**
```tsx
function PriceDisplay({ price }: { price: Price }) {
const dollars = (price.unitPrice / 100).toFixed(2)
return ${dollars}
}
```
**Helper function for consistent formatting:**
```tsx
function formatPriceFromCents(cents: number): string {
return `$${(cents / 100).toFixed(2)}`
}
// Usage
function PriceDisplay({ price }: { price: Price }) {
return {formatPriceFromCents(price.unitPrice)}
}
```
**With locale-aware formatting:**
```tsx
function formatPriceFromCents(
cents: number,
currency: string = 'USD',
locale: string = 'en-US'
): string {
return new Intl.NumberFormat(locale, {
style: 'currency',
currency,
}).format(cents / 100)
}
```
### 3.2 Display Billing Interval
**Impact: MEDIUM (clarifies subscription terms)**
Subscription prices have `intervalUnit` (day, month, year) and `intervalCount` properties. Display these clearly.
**Incorrect: ignores billing interval**
```tsx
function PriceDisplay({ price }: { price: SubscriptionPrice }) {
// Confusing: Is this $10 total? Per month? Per year?
return ${(price.unitPrice / 100).toFixed(2)}
}
```
**Correct: shows billing interval**
```tsx
function PriceDisplay({ price }: { price: SubscriptionPrice }) {
const amount = (price.unitPrice / 100).toFixed(2)
// Format interval display
let intervalLabel = ''
if (price.intervalUnit) {
if (price.intervalCount === 1) {
intervalLabel = `/${price.intervalUnit}`
} else {
intervalLabel = ` every ${price.intervalCount} ${price.intervalUnit}s`
}
}
return (
${amount}
{intervalLabel}
)
}
// Renders: "$10.00/month" or "$99.00/year" or "$5.00 every 2 weeks"
```
**Helper function:**
```tsx
function formatSubscriptionPrice(price: SubscriptionPrice): string {
const amount = (price.unitPrice / 100).toFixed(2)
if (!price.intervalUnit) {
return `$${amount}`
}
if (price.intervalCount === 1) {
return `$${amount}/${price.intervalUnit}`
}
return `$${amount} every ${price.intervalCount} ${price.intervalUnit}s`
}
```
### 3.3 Extract and Display Features
**Impact: MEDIUM (shows value proposition)**
Products have a `features` array. Extract and display feature names in pricing cards.
**Incorrect: doesn't handle missing feature names**
```tsx
function FeatureList({ product }: { product: Product }) {
return (
{product.features.map((feature) => (
// BUG: feature.name might be undefined
{feature.name}
))}
)
}
```
**Correct: filter to features with names**
```tsx
function FeatureList({ product }: { product: Product }) {
// Filter to features that have names
const displayFeatures = product.features.filter(
(feature): feature is Feature & { name: string } =>
typeof feature.name === 'string' && feature.name.length > 0
)
if (displayFeatures.length === 0) {
return null
}
return (
{displayFeatures.map((feature) => (
{feature.name}
))}
)
}
```

## 4. Current Plan Highlighting
**Impact: MEDIUM**
When displaying pricing to authenticated users, highlight which plan they're currently on to help them understand their options.
### 4.1 Detect Current Subscription
**Impact: MEDIUM (helps users understand their status)**
Use the current subscription's price ID to determine which pricing card represents the user's current plan.
**Incorrect: compares product names (unreliable)**
```tsx
function isPlanCurrent(product: Product, billing: LoadedBillingContext) {
// BUG: Product names might not be unique, or might change
return billing.currentSubscription?.product?.name === product.name
}
```
**Correct: compares price IDs**
```tsx
function isPlanCurrent(priceSlug: string, billing: LoadedBillingContext) {
// No current subscription = no current plan
if (!billing.currentSubscriptions?.length) {
return false
}
// Get the price by slug
const price = billing.getPrice(priceSlug)
if (!price) {
return false
}
// Check if any current subscription uses this price
const currentPriceIds = new Set(
billing.currentSubscriptions.map((sub) => sub.priceId)
)
return currentPriceIds.has(price.id)
}
```
**Usage in a component:**
```tsx
function PricingCard({
plan,
isCurrentPlan,
}: {
plan: PricingPlan
isCurrentPlan: boolean
}) {
return (
)
}
```
### 4.2 Disable or Style Current Plan
**Impact: MEDIUM (prevents confusing interactions)**
The "current plan" card should not have an active checkout button. Either disable or restyle the action.
**Incorrect: same button for all plans**
```tsx
function PricingCard({ plan }: { plan: PricingPlan }) {
const billing = useBilling()
const handleUpgrade = async () => {
// BUG: Allows clicking to "upgrade" to current plan
await billing.createCheckoutSession({
priceSlug: plan.slug,
successUrl: window.location.origin,
cancelUrl: window.location.href,
autoRedirect: true,
})
}
return (
)
}
```

## 5. Billing Interval Toggle
**Impact: MEDIUM**
Many pricing pages let users toggle between monthly and annual billing to compare options.
### 5.1 Monthly/Annual Toggle Pattern
**Impact: MEDIUM (improves comparison shopping)**
Implement a toggle that filters prices by billing interval.
**Basic implementation:**
```tsx
type BillingInterval = 'month' | 'year'
function PricingPage() {
const billing = useBilling()
const [interval, setInterval] = useState('month')
if (!billing.loaded || !billing.pricingModel) {
return
}
return (
)
}
```
### 5.2 Filter Prices by Interval
**Impact: MEDIUM (shows correct prices for selected interval)**
When displaying prices, filter to only show prices matching the selected billing interval.
**Incorrect: shows all prices regardless of interval**
```tsx
function PricingGrid({
interval,
pricingModel,
}: {
interval: BillingInterval
pricingModel: PricingModel
}) {
return (
{pricingModel.products.map((product) => {
// BUG: Shows first price regardless of interval selection
const price = product.prices[0]
return (
)
})}
)
}
```
---
## 6. Responsive Layout
**Impact: LOW**
Pricing grids should adapt to different screen sizes for optimal viewing.
### 6.1 Grid Layout for Pricing Cards
**Impact: LOW (improves mobile experience)**
Use CSS grid with responsive breakpoints to adjust the number of columns.
**Basic responsive grid:**
```tsx
function PricingGrid({ plans }: { plans: PricingPlan[] }) {
return (
{plans.map((plan) => (
))}
)
}
```
**Centered layout for fewer plans:**
```tsx
function PricingGrid({ plans }: { plans: PricingPlan[] }) {
// Center cards when fewer than 3 plans
const gridClass =
plans.length <= 2
? 'flex flex-wrap justify-center gap-6'
: 'grid gap-6 md:grid-cols-2 lg:grid-cols-3'
return (
{plans.map((plan) => (
))}
)
}
```
**Full-width cards on mobile:**
```tsx
function PricingCard({ plan }: { plan: PricingPlan }) {
return (
