# Guest Checkout

## Overview

Requiring account creation before purchase is one of the top causes of checkout abandonment — it adds friction for first-time buyers who do not yet trust your store enough to commit to a relationship. Enabling guest checkout and deferring account creation to after the purchase typically increases checkout completion by 20–35%. All major platforms support this with a single settings change.

## When to Use This Skill

- When checkout funnel analysis shows a significant drop-off at the account creation or login step
- When setting up a new store and deciding on account requirements
- When adding a "Buy as Guest" option to an existing checkout that currently requires login
- When optimizing first-time buyer conversion rates

## Core Instructions

### Step 1: Enable guest checkout on your platform

---

#### Shopify

Guest checkout is enabled by default on Shopify. To verify or configure it:

1. Go to **Settings → Checkout → Customer accounts**
2. Choose one of:
   - **Accounts are optional** (recommended): customers can check out as a guest or log in; Shopify shows a "Continue as guest" option
   - **Accounts are disabled**: checkout requires no account at all
   - **Accounts are required**: blocks guest checkout — avoid this unless you specifically need a members-only store
3. Click **Save**

For the post-purchase account creation prompt (so guests can save their details after buying):
1. Under **Settings → Checkout → Customer accounts**, enable **Self-serve returns** and **Order status page** — this lets guests view their order status without an account
2. Shopify automatically sends a "Create an account" link in the order confirmation email when accounts are optional

#### WooCommerce

1. Go to **WooCommerce → Settings → Accounts & Privacy**
2. Under **Guest checkout**:
   - Check **Allow customers to place orders without an account** (enables guest checkout)
   - Uncheck **Allow customers to log into an existing account during checkout** if you want to simplify the checkout form (or leave checked to offer both)
3. Under **Account creation**:
   - Check **Allow customers to create an account during checkout** — this shows an optional "Create an account" checkbox on the checkout page
   - Check **Allow customers to create an account on the "My account" page** — this lets guests create an account after ordering via the confirmation email link
4. Click **Save changes**

For post-purchase account creation, WooCommerce automatically includes an account creation prompt in the order confirmation email when the above settings are enabled.

#### BigCommerce

1. Go to **Settings → Store Setup → Account Signup**
2. Under **Customer accounts**, select **Optional — customers can check out as guests or create an account**
3. Enable **Send account creation email** — this sends a post-purchase email prompting the customer to activate an account with a single click

Alternatively, BigCommerce supports **Apple ID login** and **Google login** which let returning customers authenticate without a traditional password — lower friction than full account creation.

#### Custom / Headless

For headless storefronts, implement the guest checkout pattern with post-purchase account creation:

**Guest order flow:**
1. Email is the only required identifier — collect it at the start of checkout
2. Check if an account exists for that email; if yes, offer to log in or continue as guest
3. Place the order without linking it to a user account
4. Generate a time-limited account creation token (72 hours) and include it in the confirmation email

```javascript
// POST /api/auth/check-email — check if account exists before showing login prompt
async function checkEmail(req, res) {
  const { email } = req.body;
  const exists = await db.users.findUnique({ where: { email: email.toLowerCase() } });
  res.json({ exists: !!exists });
}

// POST /api/auth/create-account-from-order — called when guest clicks "Create account" link
async function createAccountFromOrder(req, res) {
  const { token, password } = req.body;
  const record = await db.accountCreationTokens.findUnique({ where: { token } });

  if (!record || record.expiresAt < new Date()) {
    return res.status(400).json({ error: 'Link expired — request a new one from your account page' });
  }

  const user = await db.users.create({
    data: { email: record.email, passwordHash: await hashPassword(password) },
  });

  // Associate all guest orders with this email to the new account
  await db.orders.updateMany({
    where: { guestEmail: record.email, userId: null },
    data: { userId: user.id },
  });

  await db.accountCreationTokens.delete({ where: { token } });
  res.json({ success: true });
}
```

**Order tracking without an account:**
Let guest customers track orders via order number + email, without requiring login:

```javascript
// GET /api/orders/track?orderNumber=ORDER-12345&[email protected]
async function trackGuestOrder(req, res) {
  const { orderNumber, email } = req.query;
  const order = await db.orders.findFirst({
    where: {
      orderNumber,
      OR: [{ guestEmail: email.toLowerCase() }, { user: { email: email.toLowerCase() } }],
    },
    include: { fulfillments: true },
  });
  if (!order) return res.status(404).json({ error: 'Order not found' });
  res.json({ order });
}
```

### Step 2: Optimize the post-purchase account creation prompt

The order confirmation page is the ideal time to offer account creation — the customer is in a positive, just-purchased state and has a concrete reason to create an account (tracking their order).

**Best practices for the prompt:**

- **Lead with the benefit**, not the action: "Track this order and check out faster next time" vs. "Create an account"
- **Make it one click**: show a password field only; all other details are already known from the order
- **Include in the confirmation email**: many customers miss the on-page prompt; the email gives them a 72-hour window to create the account

**Email template for post-purchase account creation:**

```
Subject: Your order #{{orderNumber}} is confirmed!

Hi {{email}},

Your order is on its way!

---
SAVE YOUR DETAILS FOR NEXT TIME
Create a free account to track your order and check out faster:
{{accountCreationUrl}}
(This link expires in 72 hours)
---
```

### Step 3: Measure guest checkout adoption

Track these metrics in Google Analytics 4 or your analytics platform:

- **Guest checkout rate**: what % of orders are placed as guest? (target: 40–60% for new customers)
- **Post-purchase account creation rate**: what % of guests create accounts within 72 hours? (target: 15–25%)
- **Checkout completion rate by type**: compare guest vs. account checkout completion rates

If guest checkout completion is significantly higher than account checkout completion, consider making accounts optional store-wide rather than having the login prompt appear prominently.

## Best Practices

- **Require only email at checkout entry** — do not ask for a password or account creation before taking payment; defer it entirely to post-purchase
- **Offer to log in, not force it** — when the email has an existing account, show both "Log in" and "Continue as guest"; never block checkout
- **Send the account creation link in the confirmation email** — many shoppers miss the on-page prompt
- **Link historical guest orders on account creation** — when a guest creates an account, transfer all prior orders with that email to their new account
- **Expire account creation tokens** — 72 hours is appropriate; long enough to read the email, short enough for security
