Building a Shopify store is only the first step. The real challenge is transforming it into a functional, smart, and sales-driven system. This is where Shopify’s vast app ecosystem comes into play. Today, thousands of apps cover almost every need — from marketing automation and shipping tools to upsell systems and product configurators. But here’s the truth: success doesn’t come from simply installing apps. It comes from choosing the right ones, integrating them properly, and ensuring they work seamlessly without slowing down your store.

At 34Devs, we focus on selecting the best apps for your business, handling the full integration, and customizing the setup to fit your brand. Our mission is to deliver Shopify apps that are not just installed, but fully working solutions that add real value to your store.

Of course, sometimes ready-made apps aren’t enough. Some clients have unique requirements that can’t be solved with off-the-shelf tools — or existing apps conflict with each other. That’s when custom app development comes into play. We build apps from scratch, tailored specifically to your Shopify store, to ensure you get exactly what you need.

What We Do

• Email & CRM integrations:

  Klaviyo, Omnisend, Mailchimp — we set up automated flows like abandoned cart reminders, welcome sequences, and customer segmentation.

• Customer reviews & social proof:

  Judge.me, Loox, Yotpo — adding trust and credibility to your product pages.

• Upsell & cross-sell systems:

  Smart recommendations that increase cart size and average order value.

• Payment & shipping integrations:

  Stripe, PayPal, Klarna, iyzico, PostFinance, plus shipping calculators and delivery solutions.

• ERP & external system integrations:

  Syncing products, stock, and orders with ERP systems like JTL-Wawi or Netsuite.

• Marketing integrations:

  Google Merchant Center, Meta Catalog, TikTok Shop — setting up catalogs, pixels, and remarketing infrastructure.

• Custom app development:

  When existing apps can’t deliver, we create custom Shopify apps — from product configurators and personalization tools to marketplace connectors.

Why It Matters

A Shopify store becomes a fully functional sales machine when the right apps are in place. The wrong choices or poorly integrated apps, on the other hand, can slow down your site and even cost you sales. Our difference is that we don’t turn your store into an “app overload.” Instead, we carefully select only the tools you need and integrate them properly.

Performance is key. More apps often mean more code, and more code can mean slower speed. That’s why, during integration, we also optimize performance — ensuring your store stays fast and reliable while gaining new functionality.

Our Process

1. Needs Analysis – We start by discussing your store’s requirements in detail.

2. App Selection – From Shopify’s App Store, we choose the most suitable tools.

3. Setup & Customization – We install, configure, and adapt apps to fit your brand and workflows.

4. Testing & Performance Checks – Making sure apps don’t conflict with each other or slow down your store.

5. Custom Development (if needed) – When no existing solution fits, we build a tailored Shopify app just for you.

Final Word

Our job isn’t just to “install apps.” It’s to make your Shopify store truly functional, optimized, and ready to sell. The right integrations streamline operations, improve customer experience, and increase revenue. And when the market doesn’t offer the right tool, we create it for you.
