Black Friday Shopify checklist for code freeze week

The worst Black Friday problems we're called in to fix have the same cause. Someone made one small change on Thursday night. A new app, a tweak to the cart, an updated discount rule. On Friday morning, checkout started misbehaving and nobody could say why.

Black Friday falls on the 28th of November 2025. By now, the rule is simple. Keep changing content and merchandising. Freeze code, apps, checkout and integrations until the weekend is over. If a change touches how people pay or how orders leave the building, it waits until December.

What you can still change safely

Freezing code doesn't mean freezing the store. Your team should still be merchandising hard this week. These changes are low risk when you check them once they're live.

• Homepage banners, hero images and announcement bars.
• Collection sort orders and featured products.
• Product copy, images and sale badges.
• Discount codes and automatic discounts that were built and tested earlier.
• Stock levels and restocks.
• Navigation links pointing to sale collections.

Even here, have a second person check each change on a phone. Mobile is where most traffic sits on the stores we look after. A banner that looks fine on a laptop can push the product grid off screen.

What should you freeze?

Anything that changes how the store works, rather than what it shows.

• Theme code, including small edits to Liquid, CSS or JavaScript.
• Installing, removing or reconfiguring apps.
• Checkout settings, payment methods and delivery options.
• Shipping rates and zones.
• Integrations with your ERP, 3PL, inventory or email platform.
• Tracking scripts and pixels.
• Domain, redirect and market settings.

The logic is about blast radius. If a banner breaks, one section looks wrong. If an app clashes with the cart, nobody can buy. Keep the risky category closed until Tuesday.

The last checks before Friday

Use today for testing, not building. Work through the full journey as a customer would.

1. Place a real order on mobile and desktop, using each payment method you offer.
2. Apply every sale discount you plan to run, and check they don't stack in ways you didn't intend.
3. Test your top five products, including variants that often sell out.
4. Check an order reaches your warehouse or 3PL and your email platform.
5. Confirm stock levels on best sellers match what's physically on the shelf.
6. Load the homepage and a busy collection on a slow mobile connection.
7. Write down who to call if payments, fulfilment or the site has a problem.

If a check fails, fix it with the smallest change that works. Switching off a problem discount is safer than rewriting it. Hiding a broken section is safer than editing its code. Save the proper fix for December.

Refund the test orders afterwards. Make sure the team knows which ones were tests, so nobody ships them.

How to run the weekend

The weekend runs from Black Friday through to Cyber Monday on the 1st of December. Plan it like a shift, not a surprise.

• Agree who watches orders, stock and customer service each day.
• Keep one channel open for problems, and one person who decides.
• Check sales, conversion and checkout errors a few times each day.
• If something breaks, roll back first and investigate second.
• Keep a short log of what happened and when.

That log is the most valuable thing you'll have next week. It turns a stressful weekend into a list of improvements.

We plan launches, sales and Black Friday as part of our ongoing work with Forty Clothing, alongside their loyalty and email programme. The pattern holds for any store. Preparation happens in October. Black Friday week is for selling.

What to do in December

When the freeze lifts, don't rush straight into new features. Spend the first week reviewing.

Look at where customers dropped off, which pages were slow and which questions filled the inbox. Compare the log with your analytics. Ask customer service what they heard most. Those questions often point straight at a missing detail on a product page or a confusing delivery message. Turn the findings into a short backlog for January, ordered by what will make the biggest difference next time.

Speed often tops that list. Our site speed checklist for Shopify stores is a practical place to start. The bigger question is who owns the backlog once the rush is over. We cover that in what ongoing Shopify support should include.

Where parallel helps

We look after live Shopify stores every month, including the quiet weeks and the busiest ones. Our support packages include monitoring and a steady rhythm of improvements. For stores with a long backlog, the Growth subscription gives you unlimited requests, worked through in order. Most tasks land in one to three business days.

If this Black Friday felt harder than it should, book a call in December and we'll plan next year's together.
