Peak-Season Checkout and Payments: What to Test Before Black Friday

Every other part of your BFCM plan — the offer, the landing page, the emails — exists to get shoppers to checkout. If checkout fails, or a customer cannot pay the way they want to, all of that work is wasted at the moment it matters most.

This guide is a test plan for your checkout and payments in the run-up to Black Friday on 27 November. Do it before the code freeze on 20 November in our Shopify BFCM 2026 Playbook.

Offer the payment methods each market expects

Payment habits differ more between countries than almost anything else in ecommerce. The table shows typical expectations; check which methods your providers support in each market before you rely on them.

Two practical points stand out. Shopify Payments is not available for stores based in India, so Indian stores use a local gateway — we covered one setup in multi-currency payments with Shopify and Razorpay. And if you sell into several markets from one store, check that each market sees the methods it expects; we cover running several markets in Diwali, Black Friday, White Friday: one Shopify store, three markets.

The test plan

Place real orders, not just test-mode ones, and refund them afterwards. Real orders exercise the parts that test mode skips: real card authentication, real fraud checks and the flow of the order into your other systems.

Payment methods

• One order with each payment method in each market you sell to.
• At least one card payment that triggers 3-D Secure authentication, if your markets use it.
• One buy-now-pay-later order near the provider’s minimum and one near its maximum order value.
• One cash on delivery order, if you offer it, through to the delivery confirmation step.

Offers and pricing

• An order with a discount code, one with an automatic discount, and one trying to combine them — check the result matches your discount combination rules.
• An order paid partly with a gift card.
• Orders in each currency, checking prices, rounding, taxes and duties shown at checkout.

After the payment

• The order confirmation email arrives, with the right delivery message for the market.
• The order reaches your fulfilment, ERP and accounting systems.
• A refund goes back to the original payment method, and a return can be processed.

Checkout customisations and apps

On Shopify Plus, checkout customisation now runs through checkout extensibility — checkout UI extensions, Shopify Functions and web pixels — which replaced checkout.liquid. If your checkout uses extensions, custom discount logic or apps that add fields, upsells or delivery options:

• Test each one with real orders in every market.
• Check what happens if the app fails: does checkout still complete?
• Freeze changes with the rest of your code on 20 November.

Fraud settings and declines

Peak season brings more genuine customers and more fraud attempts. Both sides of the balance cost money:

• Too strict, and you decline or cancel good orders — often from new customers you paid to acquire.
• Too loose, and chargebacks arrive weeks later, after the stock has gone.

Before the weekend, review your fraud rules and any fraud-protection app, make sure someone can review flagged orders quickly over the weekend, and find out where to see your decline rate by payment method. A sudden rise in declines is often the first sign of a payment problem.

Cash on delivery and buy-now-pay-later

Both can lift conversion in the markets that expect them, and both need managing at peak:

• Cash on delivery brings a higher share of refused deliveries and returns to origin. Confirming orders by message or phone before dispatch, and limiting cash on delivery for very high order values, both reduce the risk.
• Buy-now-pay-later providers set minimum and maximum order values and run their own eligibility checks. Show the option on product pages so customers know it is available before checkout.

Your fallback plan

Payment providers rarely fail, but when they do it is usually at peak. Prepare:

1. A second payment method customers can use if one fails.
2. Status pages for your payment providers and Shopify, bookmarked.
3. A named contact at each provider, with the support route for urgent issues.
4. A quick way to hide or deprioritise a failing method, and someone with the access to do it.
5. A short message ready to post on the store if customers are affected.

We cover the rest of the weekend’s monitoring and incident handling in our BFCM week survival guide.

Get your checkout checked

Checkout is the one part of the store where a small fault has a direct cost on every order. If you would like it tested before the freeze, our conversion rate optimisation team can run the test plan above across your markets and payment methods and report back.
