7 Best BigCommerce Development Agencies in 2024 (And How to Evaluate Them)

Learn what to consider when evaluating different BigCommerce agencies and discover the best BigCommerce development agencies by niche and specialty.

At SwiftOtter, we’ve been developing BigCommerce sites since 2012.

In that time, we’ve learned what is most important to eCommerce sites – the things they need and want for a successful online store.

We also know the frustrations that can arise from working with BigCommerce. Clients often come to us because either their internal team (or another agency or individual developer) is struggling to:

  • Customize their site as they wanted. BigCommerce has a variety of themes and templates, but you need technical know-how (specific to BigCommerce) for advanced customization. Without this, you’re not going to be using the platform to its fullest ability.
  • Best utlize third-party apps. Using third-party apps is key for improved site performance, security, and overall sales effectiveness. But if you don’t know how to vet the third-party apps or integrate them with your site, you can create issues for your site (from load time to security).
  • Migrate your existing site completely. Migrating your existing site into BigCommerce is often a complex process, but when managed correctly it’s extremely beneficial, especially to get your large product catalog or any custom-built functionalities you had into your new site.
  • Build a site that can scale up. Often, companies have a BigCommerce site that’s only functional at its current bandwidth, but the site’s code, functionality, and security struggle to maintain integrity as it grows. That’s the last thing you want, as returning to a poorly developed site is a headache.

These issues can be avoided if you properly vet and evaluate your BigCommerce Development agency before working with them.

In this post, we take a look at five questions that you should ask yourself when evaluating a BigCommerce development agency.

Then, we look at how we implement those must-have factors (and more) into our development process at SwiftOtter, where we specialize in developing BigCommerce stores for B2B/manufacturing companies and outdoor sporting goods stores.

And because you’re looking for a development agency, we provide a list of the 8 best BigCommerce development agencies, including ones that specialize in full-service design and development and those that are more suited for specific tasks like SEO and SEM.

5 Questions to Ask When Evaluating BigCommerce Development Agencies

Based on our experience working with companies on their BigCommerce sites – and taking the things they’ve told us that they’ve experienced working with their own teams or external teams who didn’t quite deliver – we put together this list of five questions to ask when evaluating different BigCommerce development agencies.

  • Do they have experience in BigCommerce?
  • Can they efficiently integrate third-party apps?
  • Can they migrate your existing site into BigCommerce?
  • How do they approach design and UX?
  • Do they offer post-launch and maintenance?

1. Do They Have Experience in BigCommerce?

While this may seem obvious, plenty of our clients operate under the misconception that they can hire any dev agency with experience in Shopify or Adobe Commerce and have them work on their BigCommerce site. 

While sometimes this can work, it generally means that the agency or developer is going to either a) turn in shoddy work or b) outsource a lot of the tasks to freelancers with BigCommerce experience and thus lose control over their process (and increase the cost of the overall project).

So, you want an agency with experience working within the BigCommerce platform itself. This includes an agency that has a deep understanding of BigCommerce’s platform, its codebase, templating system, data models, and more. 

Plus, they should understand the interactions between different parts of the site – such as how the storefront works with the checkout process and admin panel. 

By understanding BigCommerce’s features, the agency can make more informed decisions around order processing, payment gateways, shipping integrations, and more.

Here are some other technical capabilities your agency should be well-versed in:

  • Front-end development technologies, such as HTML, CSS, JavaScript, and responsive design principles. This is essential for creating visually appealing and user-friendly online stores that provide a seamless experience across various devices and screen sizes.
  • Server-side scripting languages such as PHP or NodeJS. These languages are often used for developing custom functionality, integrating with third-party services, and handling server-side operations like data processing and security.
  • Database management systems that are compatible with BigCommerce like MySQL, to help them better manage product catalogues, customer data, and other key store-specific info.

Plus, we recommend that you focus on agencies that work with your type of company. A BigCommerce platform will need different things based on your industry, the size of your catalogue, the services you offer, and much more.

For example, at SwiftOtter we specialize in developing BigCommerce stores for manufacturing/B2B companies and outdoor sporting goods companies. Of course our experience could lend itself to other industries, but we know the most about those types of businesses. 

This means we have more industry knowledge in those areas and can recommend plugins or developments or designs based on established best practices. 

2. Do They Have Experience With Third-Party Apps?

You will use third-party apps on your BigCommerce platform – so they can’t be an afterthought. Whatever dev agency you use needs to understand how to best integrate third-party apps to maintain site performance and security. 

When you’re looking at agencies, ask them if they have experience in integrating third-party apps such as:

Marketing and Conversion Apps:

  • Email marketing apps (e.g., Klaviyo, Mailchimp)
  • Pop-up and exit-intent apps (e.g., Justuno, Privy)
  • Loyalty and rewards programs (e.g., Smile.io, LoyaltyLion)
  • Product reviews and ratings (e.g., Yotpo, Stamped.io

Payment and Checkout Apps:

  • Alternative payment gateways (e.g., Amazon Pay, PayPal, Apple Pay)
  • Buy now, pay later solutions (e.g., Afterpay, Klarna, Affirm)
  • Fraud protection and risk management (e.g., Signifyd, Bolt)

Shipping and Fulfilment Apps:

  • Real-time shipping rate calculators (e.g., ShipperHQ, EasyPost)
  • Order tracking and shipment notifications (e.g., AfterShip, Shipstation)
  • Inventory management and fulfillment (e.g., ShipWorks, Ordoro)

Analytics and Reporting Apps:

  • Store analytics and heat mapping (e.g., Hotjar, Crazy Egg)
  • Customer behavior analytics (e.g., Glew.io, Metrilo)
  • Sales tax and accounting integrations (e.g., Avalara, QuickBooks)

Customer Support Apps:

  • Live chat and helpdesk solutions (e.g., Gorgias, Re:amaze)
  • Customer feedback and survey tools (e.g., Yotpo, Okendo)
  • Knowledge Base and self-service portals (e.g., HelpSite, Documill)

Product Customization and Personalization Apps:

  • Product customizers and designers (e.g., Inksoft, Product Personalizer)
  • Subscription and recurring billing (e.g., Bold Subscriptions, ReCharge)
  • Product bundling and upselling (e.g., Bold Bundles, Zoorix)

3. Can They Migrate Your Existing Site Effectively?

The big pain here is reconciling different data structures and data formats between two platforms – that’s what makes data mapping and data transformation so difficult.

That’s why it makes sense to find a BigCommerce development agency that also has experience in your existing platform. For example, at SwiftOtter, we don’t just work with BigCommerce, but also work with Shopify, WooCommerce, and Adobe Commerce / Magento 2.

4. How Do They Approach Design and UX?

Often agencies – even the smaller ones – struggle to fully marry their dev team and their design. This, at best, creates delays in timelines, which results in greater costs and lost revenue for you. But at worst, you can get a great design that’s not fully executed by the dev team or a well functioning blog that’s not designed towards your target audience.

When evaluating potential agencies, you want to speak to designers who understand development and developers who understand design, and you also want a unified team. 

Further, you don’t want a one-and-done job. As this kind of work is iterative. Instead, make sure you’re working with an agency that:

  • Conducts initial user research
  • Does usability testing along the way
  • Utilizes an iterative design process
  • Does  performance testing / journey mapping
  • Does A/B testing

5. Do They Offer Post-Launch Support and Maintenance? (+ Can They Build a Site that Scales with Your Business)

Often, our clients come to us because they have worked with a BigCommerce agency or developer who, once the site was launched, considered their work done.
But this isn’t the case – proper development comes with post-launch support and maintenance.

Work only with an agency that offers post-launch support and maintenance to save money and headaches.

This includes, but is not limited to:

  • Software updates and security patches. BigCommerce will release new updates and security patches that need to be set up to keep your site functional. Without post-launch support, you’re stuck doing these on your own. In our experience, they don’t get done at all or they’re done incorrectly, leading to site issues and instability.
  • Theme and app updates. Similar to the above – your site is going to be using non-native apps and plugins. They themselves will go under updates or will be affected by BigCommerce’s updates. 

Bonus Question: Are the Deliverables and Timeline Clearly Defined in the Statement of Work?

Let’s say you’ve evaluated a dev agency per the questions above and you’ve found one that you think is both the right technical fit and culture fit to help you set up your BigCommerce store.

The vetting doesn’t stop there – you want to make sure you have a specific Statement of Work (SOW) with clearly defined deliverables and timelines. 

Your SOW with any agency should have the following:

  • Deliverables listed out.
  • Turnaround time mapped.
  • Communication channels and updates defined.
  • How many iterative processes are going to be offered.
  • What does the post-launch maintenance look like

7 Best BigCommerce Development Agencies

Discover the best BigCommerce development agencies by niche and specialty.

1. SwiftOtter: for Manufacturing/B2B Companies and Outdoor Sporting Goods Companies

At SwiftOtter, we have a proven track record of helping manufacturing/B2B companies and outdoor sporting goods companies set up and maintain their BigCommerce stores.

We have been doing this kind of work since 2012 and have helped both brand-new sites and companies migrate their existing sites out of a different platform (like Magento or WooCommerce) into BigCommerce.

  • A discovery phase
  • Developing and presenting a strategy 
  • A design phase (iterative)
  • Feature & theme development (including third-party apps)
  • Post-launch testing and monitoring

Discovery

We prefer to start with a discovery phase though we have, on a case by case basis, gone right into developing and presenting a strategy.

But a thorough discovery page helps us better create a strategy in the next step.

In discovery, we want:

  • To find key information about your business and your target customers
  • Understand the scope of project 
  • Create an action plan and come up with KPIs that will help us both understand if the project is on track

Developing and Presenting a Strategy

After discovery, we will present you with a strategy to design and develop your BigCommerce store. 

This is a detailed roadmap. Of course, there may be small variations once the design and development process starts. That’s not only normal, but a good sign – as we like to adapt our plan based on new learnings and data. But these changes will always be communicated with you, our client.

Design

By doing a thorough discovery and strategy, we can now take what we’ve learned about your brand and do the initial design. The goal is to create a design that will help your business achieve its goals. 

Our team creates wireframe and low-fidelity prototypes to show you the site’s proposed structure and layout. You want to be able to see how your users will navigate your site and you want to map their entire journey.

When our wireframes are approved, we then can create more detailed mockups (using your brand’s visual elements, like your company’s typeface and brand colors).

And of course, our designers collaborate with our developers to make sure what’s benign designed can be accurately created in your BigCommerce storefront.

Feature & Theme Development

After our design process, we start developing features and themes for your BigCommerce site.

To do this, our developers use BigCommerce’s templating language, Handlebars.js. 

We use this language to create placeholders for later content (like your product information or shopping cart details). These placeholders will then get real data from the API we set up with BIgCommerce. This is what makes for seamless integration between your site’s front end and back end.

Once tested, we deploy the feature to the live site and monitor results.

Post-Launch Testing and Monitoring

When you work with SwiftOtter, we offer post-launch testing and performance monitoring.

This includes, but is not limited to:

  • Software updates and security patches. BigCommerce is consistently releasing new updates and security patches that need to be set up to keep your site functional.
  • Theme and app updates. Similar to the above – your site is going to be using non-native apps and plugins. They themselves will go under updates or will be affected by BigCommerce’s updates. 
  • Training and knowledge transfer. You’re likely working with a development agency because you don’t have developers who can handle it, either they’re lacking the skill set or simply the availability. Either way, you want to make sure your internal dev team understands your new site. This empowers you to make choices that are in the best interest for your BigCommerce store, without being tied to a single agency.

We offer the best service when it comes to BigCommerce development, including:

  • Theme Customization
  • App and Plugin Integration
  • Custom Feature Development

This means they’re a good agency for after your site has been launched and tested. Now, generally a good dev and design agency will create your site with conversion rates in mind. And because a good site will also provide post-launch testing and maintenance, that means they can also help with conversion rates.

But still, some sites may need more help for specific landing pages or may not want to work with their existing agency. In these cases, an agency like Command C can take what you already have and improve it.

Command C will:

  • Conduct research and perform analysis. This agency looks at your existing customer base. They do things like heat map testing to see where customers are hitting the most.
  • Run experiments: Once they have their hypothesis on what will improve your site’s conversion rate, they put it to test and look at the results. 
  • Implement & Monitor: After they have run an experiment and have the most likely to succeed approach, they will develop it on your site and monitor the results. They will do this a few times to improve your site’s conversion rates.
