How to Prepare Your Shopify Store for Black Friday & Cyber Monday 2026

Black Friday 2026 falls on Friday, November 27, and Cyber Monday on November 30. Most stores we work with now run the whole week, and their customers start browsing weeks earlier. This guide is what we tell our Shopify and Shopify Plus clients in the last weeks before the peak: what to look at in last year's numbers, which changes to make now and which to leave until January, and what to do after the weekend so the new customers come back. It draws on our own projects and on two episodes of our podcast about Black Friday, plus guests who talked about margins, retention and traffic peaks. We checked every Shopify feature, date and legal rule in this article on November 11, 2026.

What changed since last Black Friday

The peak keeps growing, but more of it now happens on phones and through AI assistants, and a few Shopify changes affect how you set up the sale:

• Last year set a record. Shopify merchants sold $14.6 billion over Black Friday–Cyber Monday 2025, up 27% on 2024, with an average cart of $114.70. 16% of orders were cross-border.
• This year is expected to be bigger again. Adobe forecasts $12.9 billion in US online spending on Black Friday 2026 (up 9.2%) and $15.1 billion on Cyber Monday, with 57.4% of holiday spending on mobile and discounts peaking at up to 30%.
• AI assistants now send shoppers. Salesforce estimates that AI and agents influenced about 20% of global Cyber Week 2025 orders, worth $67 billion. Since March 2026, Shopify makes products discoverable in ChatGPT, Copilot and Google's AI Mode through Shopify Catalog.
• Shopify Scripts are gone. Scripts stopped running on June 30, 2026. If last year's tiered discounts or free gifts on Shopify Plus ran on a Script, they need to be rebuilt as Shopify Functions or native discounts before the sale.
• Launches can be scheduled and rolled back. Shopify Rollouts bundle theme, discount and catalog changes into one timed release that reverts on its own.

Start with last year's numbers, not this year's ideas

The most useful Black Friday preparation happens in a spreadsheet. On our podcast, Maciek put it this way: "Historical data from your own store is a treasure map." Before you plan offers, pull the same handful of metrics for last year's peak, and keep them in one place so you can compare year to year:

• Conversion rate split by channel, device and product category. A single store-wide conversion rate hides the problem. If mobile converts at half the desktop rate, that's where the work is.
• Sales by day and by hour. If your promotion ran for a week, see how sales spread across it. Look at the peak hour too: conversion usually rises with traffic, and if it fell at your busiest hour, something broke (speed, an app, stock, the checkout).
• Best sellers versus surprise sellers. Compare the categories that sold during the sale with your best sellers across the year, and note products that only sold because of the discount.
• Products bought together. Shopify's analytics has a report on products often bought together. Use it to set up bundles and cross-sells instead of guessing.
• Returns by product and by payment method. A payment method can lift average order value and still lose money if those orders come back more often and carry a higher fee.
• Returns and complaints by carrier. Customers rarely separate the courier from your store, and slow or damaged deliveries end up in your reviews.

Scale this to your size. A store doing its first serious Black Friday needs conversion, average order value and revenue by channel. A brand doing millions a year should go down to segments, cohorts and hours. We talk through the full list in What to analyze during Black Friday and Cyber Monday (in Polish, with an English transcript).

One habit our clients swear by: hold the retrospective in the first week of December, while everyone still remembers what happened, and save it next to the numbers. Next October you'll start from that document, not from memory.

Do the margin math before you choose a discount

A discount doesn't lower what the product cost you. It comes straight out of your margin. Wojciech Płona, a finance advisor to ecommerce companies, gave a simple example on our podcast: you buy a bottle for 80 and sell it for 100, so you make 20. Take 10 off for Black Friday and you now make 10, so you have to sell twice as many bottles just to earn the same. His point was that many store owners discount on the assumption they'll sell more and never check whether they did.

Before you set the offer, work out for each discounted product or category how many more units, or how much larger a basket, you need to break even. Then pick the mechanic that protects margin best:

Some of our clients use a "traffic builder" approach: a few well-known products at a thin margin to bring people in, and the profit made on add-ons and cross-sells. It works only when the cross-sell is set up before the traffic arrives.

If you sell in the EU, the price rules apply during the sale. Under the Omnibus Directive, every price reduction must show the lowest price from the 30 days before the discount. Raising prices in October so the November discount looks bigger is exactly what the rule targets, as Dr Zuzanna Witek explained in our episode on running a legal ecommerce business (in Polish). In Poland, the consumer authority UOKiK expects the label to say plainly that it's the lowest price from the 30 days before the reduction; vague labels such as "reference price" don't meet the rule. On Shopify, the compare-at price is not automatically that 30-day low, so check how your theme or app calculates it. This matters more now that Shopify Catalog shows compare-at prices to shoppers in AI assistants.

What to change now and what to leave until January

Four weeks before the peak is not the time for a new theme, a new app stack or a platform migration. On our podcast we called it tightening the screws rather than rebuilding the machine: small fixes that remove friction, tested before the traffic arrives. We also tell clients planning a migration to Shopify not to schedule the launch close to Black Friday, because a project that slips by a few weeks lands right on the busiest days of the year.

Worth doing now:

• Remove what slows the store down. Uninstall apps you no longer use (their scripts often stay in the theme), remove extra tracking scripts such as session recording tools you added for one test, and compress images added during the year. This is quick and doesn't touch your theme code. For deeper work, see our Shopify speed optimization service.
• Walk through every flow on a phone. Add to cart, discount codes, the checkout, returns, password reset, gift cards. Do it on mobile first, because that's where most Black Friday orders come from. Adobe expects 57.4% of US holiday online spending this season to happen on phones.
• Test discount combinations. Check that codes combine (or don't) the way you intend, that automatic discounts don't stack into a loss, and that the Omnibus "lowest price" shows correctly on sale items.
• Schedule the launch instead of doing it by hand. Rollouts (in Markets) let you prepare the sale theme, discounts and catalog prices in advance, publish them together at a set time, and revert automatically when the sale ends. On Shopify Plus, Launchpad does the same for prices, product releases and theme switches. Nobody should be changing prices by hand at midnight.
• Make the sale easy to find. A sale category in the main navigation, a clear banner, a countdown for the end of the promotion, low-stock and "back in stock" notices on product pages.
• Set up stock alerts. Low-stock alerts in the admin let you pull a product or switch to back-in-stock notifications before customers try to buy something that's gone.

Leave until January: a theme change, a checkout redesign, a new ERP or 3PL integration, a new loyalty platform, and anything else that needs a week of testing to trust. If your checkout still has customizations that predate Checkout Extensibility, check them now rather than in peak week. Also check your discount setup against Shopify's limits: a store can have up to 25 active automatic discounts, and stacking several product discounts on the same line item is a Shopify Plus feature.

Will Shopify handle the traffic?

The platform will. During Black Friday 2025, Shopify merchants together peaked at $5.1 million in sales per minute, at 12:01 pm Eastern time. Maurice Junghans, our guest from Shopify, pointed to brands such as ESN and More Nutrition, whose weekly drops bring tens of thousands of checkouts per minute. In the conversation with Maurice Junghans, Tomek Runowicz, who co-hosts our podcast, said that in all the years we've built on Shopify, our merchants have never had a problem with the platform during Black Friday or Cyber Monday. Maciek added the other side: inbound requests to our agency spike after Black Friday, mostly from brands whose self-hosted stores couldn't cope.

What can still fail is everything around Shopify:

• Apps that call their own servers. Reviews, search, upsell and personalization apps run on their providers' infrastructure. Ask them about their peak readiness, and know which ones the store can live without for an hour.
• Integrations. ERP, PIM and warehouse syncs that run every few minutes on a normal day can fall behind under ten times the orders. Overselling usually starts here.
• Your team and your warehouse. If 1% of customers usually write to support, that 1% of Black Friday traffic is hundreds of messages. Plan extra people for support and packing, not just for marketing.

Write a short plan B for the likely failures: an app goes down, a product sells out in an hour, a carrier stops collecting, a discount code leaks. Decide in advance who does what, so nobody makes those calls in a panic on Friday night.

Plan the campaign weeks before the weekend

Black Friday is no longer one day. Adobe expects Cyber Week 2026, from Thanksgiving to Cyber Monday, to bring $47.5 billion in US online spending, and our clients usually get better results from a sale spread over a week than from a single day with communication starting a few weeks earlier. Treat the weeks before Black Friday as part of the campaign:

• Warm up your list. Tease the sale by email and SMS from early November, and give subscribers and loyalty members early access. On the podcast, Maciek said email is the main source of traffic and sales during Black Friday for many of our clients, precisely because it reaches existing customers. Our guide to Klaviyo for Shopify covers the flows to set up.
• Separate loyal and new customers in your messages. Existing customers get a reward for staying (earlier access, a better offer, first choice). New customers get a reason to come back after the sale.
• Use price-drop and back-in-stock alerts for people who viewed or saved products in October. They've already decided what they want.
• Check deliverability before you send three times your normal volume. Gmail, Yahoo and Outlook enforce sender rules for bulk senders, and a spike in complaints during Black Friday week can push your emails into spam for weeks.

Payments, delivery and support under load

Customers who can't pay the way they want leave at checkout, so check your payment methods against your markets now. Shop Pay was used for 32% of orders on Shopify during BFCM 2025. Shop Pay Installments is available in the US, Canada and the UK (with Australia in early access), but not in the EU, so European stores need a local buy now, pay later provider. In Poland that means BLIK and pay-by-link alongside cards, and buy now, pay later options such as PayPo. After the sale, compare returns by payment method, as described above, before you decide to promote one more heavily.

On delivery, under-promise. If you know shipping will slow down, say so on the product page and at checkout, and publish the last order date for Christmas delivery early. Make returns easy to start, because Black Friday orders include many gifts.

On support, prepare answers to the questions that will repeat: delivery times, returns, order changes, discount codes. Use saved replies in your helpdesk, a chat that can answer the routine questions and pass the rest to a person, and an updated FAQ page. Our conversation with Yohan Loyer from Gorgias covers how AI agents handle this kind of peak in customer service.

Many reviews get written in the weeks after Black Friday, because that's when the most orders arrive. A smooth delivery and a quick answer to a problem are worth more than any review request email.

Make your offers visible in AI search

Shoppers increasingly ask an assistant before they open a store. Adobe measured a 760% increase in traffic from generative AI tools to US retail sites between November 1 and December 1, 2025, compared with the year before. The numbers start from a small base, but these visitors arrive with a short list already made.

What decides whether your products are on that list is mostly product data, not a special AI setup:

• Complete, consistent product data. Clear titles, variants, sizes, materials and stock, and the same price on the product page, in Shopify Catalog and in your Google Merchant Center feed.
• Policies an assistant can read. Delivery times, the last order date for Christmas, return terms, written as plain text on the store, not only in an image or a pop-up.
• Correct sale prices. If you sell in the EU, make sure the price shown as "before" is the 30-day lowest price, because Shopify Catalog shows compare-at prices to AI shoppers automatically.
• Attribution. Tag AI referrals in your analytics now so you can see after the sale what they brought in.

After the weekend, turn deal hunters into customers

Black Friday customers come back less often than anyone else. Jędrzej Przeździęk, CMO at OpenGift.pl, said on our episode about retention (in Polish, with an English transcript) that customers acquired through "buy now" Black Friday campaigns form cohorts with much lower retention than the rest, because they bought on impulse or bought a gift. His conclusion: retention starts with acquiring the right customers.

So plan December and January now:

• Tag the Black Friday cohort in Shopify or Klaviyo and track its second purchase rate separately from the rest of your customers.
• Send onboarding, not more discounts. A few emails about the brand, product care and how to get the most from what they bought, before you ask for the next order.
• Time the next offer to when your typical customer buys again, not to the next promotion in your calendar.
• Give points a reason to be used in the quiet weeks after the holidays. Our guide to loyalty programs on Shopify shows how to set this up.

A Black Friday checklist by week

Frequently asked questions

When should I start preparing my Shopify store for Black Friday?

Six to eight weeks before is comfortable: enough time to analyze last year, plan offers and order stock. If you're starting later, focus on the quick fixes in this guide and leave larger projects until January.

When should I freeze changes to the store?

Stop code and theme changes about a week before Black Friday, so around November 20, 2026. After that, only scheduled content (banners, prices, discounts) and urgent fixes.

Can Shopify handle Black Friday traffic?

Yes. Shopify's infrastructure handled a peak of $5.1 million in sales per minute across its merchants in 2025. The risks are in third-party apps, integrations with your ERP or warehouse, and your own team's capacity.

Do I have to show the lowest price from the last 30 days during Black Friday sales in the EU?

Yes. Under the Omnibus Directive, every announced price reduction must show the lowest price applied in the 30 days before the discount. On Shopify, check that your compare-at price or price app shows that value, not just the regular price.
