Guest Checkout

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

// 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:

// 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
