Opklopper

Brand-focused Shopify Plus agency, without the agency overhead | D2C & B2B

Opklopper is a brand-led boutique e-commerce agency and an official Shopify Plus Partner based in Amsterdam. We translate brand identity into custom Shopify and Shopify Plus experiences where brand experience, UX, and commerce come together. We design, build, redesign, migrate, and optimize Shopify stores for growing D2C, B2B, and hybrid commerce brands across the Netherlands and Belgium.

We’ve worked with 100+ brands, delivering 100+ Shopify cases documented in our public portfolio—across 250+ Shopify projects. Fashion is one of our strongest verticals, with 30+ publicly documented Shopify and Shopify Plus fashion cases. We’ve also collected 100+ public client reviews. We combine e-commerce strategy, brand-led UX/UI, custom Shopify development, technical SEO, CRO, and preparation for AI-driven search and product discovery within one experienced senior team.

Our core expertise:

New Shopify stores: custom Shopify and Shopify Plus storefronts where brand identity, custom UX/UI, scalable technology, product discovery, tracking, and technical SEO all come together. We build from a blank canvas or an existing brand manual—so you start with a strong foundation for search engines and AI shopping channels.
Shopify redesigns: refreshing existing stores based on a brand manual, rebrand, or commercial growth phase, with a focus on brand experience, custom UX/UI, mobile usability, conversion, performance, and maintainability.
Replatforming to Shopify: controlled migrations from Magento, WooCommerce, Lightspeed, Shopware, PrestaShop, and custom platforms—covering data, URL mapping, redirects, tracking, technical SEO, QA, and go-live.
Shopify B2B and D2C: business accounts, customer-specific pricing logic, catalogs, bulk orders, and separate or combined B2B and D2C commerce setups.
Shopify SEO, GEO, and CRO: technical SEO, product and collection architecture, structured data, internal linking, performance, conversion optimization, and preparation for better visibility in ChatGPT, Google AI, and other AI-driven search and discovery environments.
International commerce and integrations: Shopify Markets and integrations with ERP, WMS, PIM, POS, fulfillment, accounting, and marketing software.
Shopify optimization and ongoing improvement: structural enhancements to existing Shopify stores across UX, development, performance, SEO, GEO, CRO, tracking, and new functionality.

Who is Opklopper for?

We’re a great fit for growing brands in fashion, footwear, food, FMCG, gifting, toys, lifestyle, retail, and B2B/wholesale that need more than a standard Shopify theme or a standalone developer.

Fashion is one of our strongest categories. Our public portfolio includes 30+ Shopify fashion cases for brands including D2C fashion labels, multi-brand retail, streetwear, footwear, activewear, accessories, and omnichannel fashion commerce.

Typical projects include a new custom Shopify store, a brand-led redesign, a controlled replatforming, or a scalable B2B and D2C solution. For new builds, we also set up the technical foundation for modern product discovery—clear product structures, complete product data, relevant structured data, and content that’s easy for customers, search engines, and AI systems to understand.

Why choose Opklopper?

Clients work directly with experienced strategists, designers, developers, and project managers. That means personal collaboration, clear ownership, and short communication lines.

Our approach is brand-led: brand identity and brand experience are the starting point, and then we bring UX/UI, Shopify development, and commercial optimization together within a single storefront.

This way, you get the quality and technical depth of a high-end Shopify agency, with the speed and senior attention of a boutique team—without unnecessary enterprise overhead.

We don’t just look at what your store looks like—we also look at how products are found, understood, compared, and purchased. After launch, we can stay involved in CRO, technical improvements, SEO, GEO/AEO, new functionality, and the ongoing, structural development of your Shopify setup.

100+ brands. 100+ documented cases. 30+ fashion cases. 250+ Shopify projects. 100+ public client reviews.

Typical project budgets range from €10,000 to €25,000. More complex Shopify Plus, B2B, replatforming, and integration projects may be higher.

I wouldn’t recommend Bureau Opklopper as a partner. Even though the final design of our webshop looks good, the process and the functionality fell short in multiple areas. The communication was the biggest letdown. During the meetings, high expectations were set, but in the quotation it turned out that many of our wishes were toned down. Over time, it became increasingly clear by email that what had been promised verbally wasn’t being delivered. A lot of the design elements remained as textual ideas instead of being worked out into actual designs—for example, the desired “shop the look” page. The go-live also happened without clear coordination. We were informed by email that the webshop would go live. When we immediately started testing, we were asked to stay off it temporarily, with no further update. It didn’t feel like a careful, joint handover. Communication happened almost entirely by email, which led to an unnecessary amount of back-and-forth. Small adjustments were presented as a “favor,” while in reality they were minimal pieces of work. On top of that, we spent our own hours testing the webshop—something, in our view, the bureau should have handled. Recently, we had the webshop tested by another party because our original goal—a webshop that increases conversions—was not achieved. That test showed the site is mainly optimized for desktop; mobile scored only 43%. And that’s where most of our customers are. Bureau Opklopper should have been alert to this. We now have a functioning basic webshop, but on our last legitimate requests within the handover phase, no further response was given. In our opinion, this was something that still could—and should—have been done. — Update based on the response below: During the kickoff, it was explicitly stated that there would be no problem using the theme we had already purchased. We even suggested at the time that if needed, we could buy a different theme. Bureau Opklopper said it wasn’t necessary; they could work with it well and had checked the theme. So it’s quite remarkable to now learn that, according to them, the theme would still be the problem. With our current theme, there’s nothing wrong content-wise. The programmer we’re dealing with now has also made no comments about it. This response only confirms what I already wrote about Opklopper. Very disappointing. Opklopper chose to adjust their response based on my update. If anyone is interested in the actual response, I still have a screenshot saved. — Update after Bureau Opklopper’s adjusted response on March 20: Opklopper can’t know that the conversion was increased: Opklopper has been removed from our environment for quite some time. This was done by a developer, because apparently Opklopper could still keep an eye on things in the background. Of course, we never received an email as stated below. In our view, we’ll leave it at that. Let it be very clear for any future potential collaborations what you can expect from this bureau.

Provider's response

Hi Nancy, Thanks for the feedback. Let’s touch base about this by email. Update March 20: The task we were given was to deliver a custom design with a relatively limited budget and a short deadline, and to update the theme that had already been purchased—via an unknown platform. That requires a clear scoping and setting of expectations, which is something we spend a lot of time on during the proposal stage, to make sure expectations on both sides are as clear as possible. We did that, and the result—despite the challenges we faced—is something we’re genuinely proud of. You received a premium webshop for the lowest price, and we’re proud of the outcome. That said, it’s incredibly frustrating that your template turned out to be so poor when it comes to Core Web Vitals. I can imagine you’re not very happy about it either, and neither are we. But we had to work with what we had in order to meet the assignment requirements. I take your feedback to heart, and we’ve decided that going forward we’ll only take on this kind of project with a very clear disclaimer: themes purchased outside the official channels come with risks. If I could go back in time, I would not have been able to find a way around the hard deadline and I would have declined the assignment, because we can’t guarantee the quality we, as an agency, strive for. I also filed an official complaint with the theme’s developer, in the hope that other parties won’t make the same mistake and end up buying a theme that has technical issues. Fortunately, the conversion rate increased significantly, and overall it was a strong step forward—we were able to prove again that our knowledge of conversion optimization is effective. Kind regards from everyone at Opklopper, and again thank you for this feedback. It confirms that we need to be even stricter with our own processes—I really appreciate it. Warm regards, Opklopper

Today I spoke with Simon van Opklopper. What a great conversation partner—also when it comes to technical matters. As developers, it’s nice to occasionally discuss certain choices and trade-offs with each other and help one another along the way. A great choice if you’re thinking about starting your own web shop! Simon and his team can help you with all your questions and needs!

Provider's response

Hey Dennis, Thanks so much for your great review! I felt the same way—the conversation was really enjoyable. It’s always valuable to be able to sync up with another developer and talk through the tech and the different trade-offs that come with it. Sometimes you just need to dive deep for a moment to set the right direction. Great that our brainstorming session and the advice helped get you moving again. Feel free to reach out anytime in the future if you want to spar about something, or if we can support you with anything. Best regards, Opklopper

We’re really happy with the result that Opklopper delivered. It’s not a standard website, but one with a lively look—where our story and our product could be front and center. Smooth communication and creative thinking made all the difference for us. We’d definitely recommend Opklopper if you’re looking to build or redesign your website.

Provider's response

Hey Corné, Thanks so much for the kind words! Let’s be honest: building a LEGO webshop is, of course, our dream project. It gave us the freedom to fully let our creativity run wild, and while we were putting everything together, we seriously felt like kids again. It’s great to hear that the vibrant look is exactly what you were hoping for! We’re now already looking forward to our next weekly SEO brainstorm and advice session, so we can keep building together on the shop’s growth. And you know the deal: if you’re in the Amsterdam area, be sure to stop by for a good cup of coffee! Warm regards from everyone at Opklopper!

Great experience with Opklopper—especially with Simon. His West Frisian background means he approaches situations in a hands-on way.

Provider's response

Hey Aron, Thanks for the positive feedback. Looking back, we had a really great collaboration—using relatively limited resources and a short timeline, we still managed to give the webshop a major update. And with the TV segment coming up soon, I’m really looking forward to the impact of the improved webshop, along with the increased reach and number of visitors—hopefully (fingers crossed 🤞) leading to a big wave of orders. Also, thank you for trusting us to carry out our creative vision—through unique design elements—to strengthen the brand presence. That takes guts, and it’s a trait I unfortunately don’t see very often in entrepreneurs. Talk to you soon! Best regards, Team Opklopper

Really great team to work with. They think along with the business, are flexible, knowledgeable, and communicate really well. Thanks for everything!

Provider's response

Thanks, Jesse, for the kind words! We look back on an incredibly enjoyable collaboration, and you’ll always have a special place in our hearts! Have a great trip to Japan—I’m looking forward to your stories. Soon, a beer with chicken? That’s probably your favorite, right? ;-) On behalf of everyone at Opklopper: 1,000 thanks, and we hope to see you for many years to come, as more than just someone we were lucky enough to work with. Greetings from the Brouwersgracht, Simon

I recently collaborated with Opklopper on developing a design, and I’m very happy with the result. Communication was smooth and clear, which made for an efficient process. Simon and his team actively thought along with us. We were kept up to date throughout the entire project. The collaboration was professional, open, and enjoyable.

Provider's response

Hey Jelmer, thanks so much for your positive feedback. It’s been great to look back on a genuinely positive collaboration, where we helped strongly position the Sessions Community brand within a custom website focused on the brand and storytelling. We’ll continue to be on hand as both advisors and implementers to help turn your online lead machine into a success! Best regards from Amsterdam, Team Opklopper

I’m very happy with my collaboration with Opklopper. From the first contact, they thought along with me and I felt taken seriously as an entrepreneur. The communication was clear, fast, and professional. My wishes were translated into a clear, modern website, and I could tell there was real attention to quality and detail. What I appreciate most is that Opklopper doesn’t just execute—they also think along and advise when needed. That builds trust. I look back on this collaboration with a great feeling and would definitely work with Opklopper again in the future. Absolutely recommended for entrepreneurs looking for a reliable partner for their website.

Provider's response

Hi Gürkan, What a lovely review—thank you so much! At Opklopper, we really value clear communication. As an entrepreneur, you need to feel like you’re being heard. It’s great that this has been translated into a new clothing brand and webshop that we can both be proud of! Thanks for the trust you’ve placed in our team. We look forward to working with you again in the future! Best regards from Amsterdam, The Opklopper team

We asked Simon and the team to help us find an international market for my Mum's paintings, they created a beautiful site and held our hand through the whole process. And she actually now sells paintings, so...

Provider's response

Thank you for this lovely review Rob! Helping your mum take her art to an international market was genuinely special for us. Building a site that does justice to her paintings and then seeing them actually sell, is exactly why we do what we do. Thanks for trusting Opklopper, and we wish her many more sales to come!
