Everything you need to know about an eCommerce agency

How do eCommerce agencies support businesses’ long-term growth?

One of the most impactful ways eCommerce agencies support growth is by curating bespoke roadmaps according to their objectives and store size.

These firms study customer behavior, understand what a good shopping experience entails, can easily identify emerging trends, and adjust campaigns in real time.

One of the greatest challenge eCommerce businesses face are high cart abandonment rates. The average mobile cart abandonment rate in 2025 was 76.9%.

So, if performance data indicates that mobile users abandon carts at a higher rate than anticipated, eCommerce providers can optimize the mobile checkout and implement faster payment integrations.

ECommerce agencies can also help businesses expand their online sales by setting up and managing marketplace accounts, social commerce integrations, and omnichannel marketing.

These tactics are twofold beneficial: they diversify revenue streams and nurture resilience against market fluctuations.

Also, considering that the probability of selling to an existing customer is 60% to 70%, compared to just 5% to 20% for a new prospect, nurturing customer loyalty remains crucial for cost efficiency.

In that regard, eCommerce companies can propel businesses’ customer retention strategies through personalized email campaigns, loyalty programs, and customer experience optimization to make sure buyers keep coming back.

Can these firms help me determine if I need a store revamp or platform migration?

Yes, eCommerce companies offer audit services through which they analyze your current tech stack, performance metrics, site navigation, and user experience (UX) to provide an informed recommendation.

If your issues are purely visual or related to user flow, a simple design/functionality revamp will likely be sufficient.

If your issues are structural, security-related, or limiting your growth, a migration is likely required.

These audits are intended to identify friction points in the customer journey and bottlenecks causing high cart abandonment.

The technical assessment covers analysis of page load speeds, server response times, mobile optimization, code quality, outdates components, and security vulnerabilities.

Notably, if your backend functionality still meets your business needs, but the design is outdated, not converting well, the navigation is hard, or the features are on the older side, a re-design or front-end update will likely be the suggestion.

But, if the site crashes during peak traffic, cannot handle increased product/order volume, and the current platform cannot connect with third-party tools (ERP, CRM) or lacks essential, modern features, a platform migration will be recommended.

Overall, eCommerce agencies can calculate the total cost of ownership (TCO) and compare the costs of fixing your current, outdated system versus the investment in migrating to a new eCommerce platform.

How to choose the best eCommerce agency for my project?

When choosing between eCommerce companies, it’s important to take into consideration the following:

1. Experience with the desired eCommerce platform
   Review the agency’s portfolio to confirm it has hands-on experience with leading platforms such as Shopify, Magento, BigCommerce, and WooCommerce.
2. Conversion-oriented design practices
   Read or inquire about their design processes. Make sure they are centered around conversion rates, A/B testing, and responsive design for mobile-first audiences.
3. Maximizing the data
   Ask if the eCommerce agency uses analytics, heatmaps, and behavioral tracking to gain valuable insights into the user experience and eCommerce sales performance.
4. Diversity across industries
   Experienced eCommerce companies are well-versed into the nuances of a wide range of industries such as online retail, fashion, financial services, technology, healthcare, and B2B commerce.
5. Proven measurable results
   Review their past work and look for examples that demonstrate improvements in conversion rates, traffic, time-on-site, and most importantly, reduced cart abandonment.
6. Good industry standing
   Read third-party reviews on Google and DesignRush to learn more about the firm’s creative output, reliability, communication, code quality, and overall, client satisfaction.

DesignRush sustains a directory of over 40,000 agencies categorized by service category, location, expertise, and reviews. We build our database in two ways:

• Our dedicated team of agency experts actively searches the web for top-performing companies. We then pull information from their websites, online presence, and client testimonials to verify their status and qualifications prior to listing.
• The agencies listed get notified of their profiles on the website and they can choose to claim it or not, which suggests their availability for more collaborations.

Agencies can also reach out to DesignRush and must go through the verification process prior to being listed.
