A Developer’s Guide to Surviving Black Friday

Written by Thijs Dekker | Oct 7, 2025 12:24:33 PM

Thijs here, I’m one of the developers helping our clients get their Shopware stores ready for the madness that is Black Friday. I’ve seen a lot of stores go through peak traffic moments, and trust me, those days can be either fun… or chaotic. The difference usually comes down to one thing: preparation.

So, before we all dive headfirst into discounts and campaign setups, here are a few recommendations from my developer’s perspective. These tips will help keep your store fast, stable, and stress-free when the orders start coming in. 

1. Start early, plan and set everything up in advance

Don't wait until the last week to set up your campaigns, discounts, categories, or marketing materials. Preparing everything in advance gives you time to test, make adjustments, and ensures both you and your technical team have time to address any issues that might arise.

2. Test your webshop (multiple times)

Your store might work fine today, but will it still perform under Black Friday traffic? Test all flows in the weeks leading up to the event:

  • Add to cart

  • Checkout

  • Discount application

  • Mobile responsiveness

  • Page load speed

  • Error handling

Catching bugs now is far better than fixing them during peak sales hours.

3. Evaluate hosting & performance needs

Peak traffic can overwhelm your current setup. Now is the time to:

  • Check if your server can handle increased load

  • Consider moving to scalable hosting (e.g., auto-scaling cloud hosting)

  • Run load tests if possible

A slow or crashing site will cost you sales, often more than upgrading your hosting plan would.

4. Spread traffic across multiple days

If your promotion strategy allows, consider running deals over several days instead of just Black Friday. This:

  • Reduces peak load on your servers

  • Gives your fulfillment team more breathing room

  • Provides a better shopping experience for your customers

5. Make deals easy to find

During Black Friday, customers are coming specifically for deals, don’t make them search. Set up a dedicated Black Friday collection or category, and:

  • Add it clearly in your main navigation

  • Highlight it on your homepage

  • Link to it in all your campaign emails

This improves conversion by reducing friction in the shopping journey.

6. Avoid discount codes

While discount codes are common, they introduce friction at checkout and increase the chance of user error or abandoned carts. A better approach:

  • Apply discounts directly to products

  • Let customers see the final price immediately

If you must use discount codes, test them thoroughly on all device types and checkout scenarios before launch.

7. Use cross-selling to promote non-discounted products

Not everything has to be discounted. Use cross-selling to feature full-price or higher-margin products alongside your Black Friday deals. Customers coming in for one item may be tempted to add more.

8. Automate wherever possible

The more you automate now, the less you’ll have to manage during the rush. Automate:

  • Discount scheduling

  • Banner visibility

  • Inventory rules

  • Email sequences

This allows you to focus on packing orders, responding to customers, and running live promotions, not fiddling with backend settings during peak traffic.

9. Avoid new feature releases right before Black Friday

As tempting as it is to launch that new feature or redesign, the week before Black Friday is not the time. New releases introduce bugs and instability, often in places you won’t notice until customers do. Lock down your store and focus on stability.

My final thoughts

The key to a successful Black Friday isn’t just good deals, it’s also a fast, stable, and stress-free customer experience backed by thorough preparation. Start early, test often, automate smartly, and stay focused on the basics. As your technical partner, we’re here to support you every step of the way, before, during, and after the rush.
