WooCommerce Review from Amanda Viviano
We hired Qolos to build our local florist shop's website on WordPress and WooCommerce, and we couldn't be happier with the results. From the start, they took the time to understand our business and created a site that's not only beautiful but easy for our customers to browse and shop.The WooCommerce setup was seamless, our online ordering works exactly the way we needed it to. But what really sets Qolos apart is their ongoing monthly maintenance. We never have to worry about updates, security, or technical issues because they stay on top of everything. Any time we've had a question or a small change request, they've been responsive and professional.As a small local business, it means a lot to work with a team that genuinely cares about keeping our site running smoothly. Qolos has been a true partner, not just a vendor. Highly recommend them to any local business looking for reliable web design and maintenance!
Web Development Review from Sanjay Singh
I kept getting negative reviews about my app for technical glitches, heating issues, functionality, loading time, crashing, and more bugs. So, I reached out to QOLOS after going through 2-3 renowned review platforms. I explained my app issue to the team, and they did tremendous work with their mobile testing solutions. Also, I wanted to build a website for my app. They created a feature-rich and seamless website.
Shopify Review from Sarah Nesheim
Working with QOLOS was the best decision I have made in regards to scaling my business. They are professional, so creative, they communicate every step of the way and their pricing is fair for the highest quality work. The designer of our logo and website did it well and I am so impressed and proud of the final product! the designer listened and knew exactly what I wanted which made the process so simple. Seriously could not recommend QOLOS more!

We were impressed with their excellent organizational standards. Ziffity Solutions was successful in maintaining the site and replacing its framework, ensuring the project's success. The team used project boards and a ticketing tool to stay on track and efficiently address issues. Their strong Magento capabilities stood out, as did their effective processes.
Magento Review from Undisclosed
Their overall knowledge and understanding of Magento were impressive. The new site met the client's expectations. In fact, it was significantly better than their old website, especially in terms of design. Despite initial issues in communication, the Ziffity Solutions LLC team eventually solved them satisfactorily. They also followed best practices for development.

Veronica's Review Sourced from Google
I agree with the other review. This company claims that they can build websites and that they are located in Modesto, California which is not true. I have been calling them for weeks and so far no response. When I told them that I wanted a refund, they quiclky put some items on the website. They are very dishonest

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.
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.
When choosing between eCommerce companies, it’s important to take into consideration the following:
We compiled a list of eCommerce companies across different price points to help you find a vendor that’s within your spending expectations.

ECommerce companies offer development and design services that cover the entire digital commerce ecosystem. Primarily, they ideate, design, build, maintain, and optimize web sites for Shopify, Magento, WooCommerce, BigCommerce, and custom platforms.
Their core eCommerce portfolio is often complemented by digital marketing services such as search engine optimization (SEO), pay-per-click (PPC), content marketing, and conversion rate optimization (CRO), to name a few. Other key services include performance tracking, audience research, product listing optimizing, inventory management, sponsored ad management, and online marketplace management for Amazon, eBay, and Etsy.
ECommerce web development costs from $5,000 to $20,000+, with the platform choice and development complexity accounting for the biggest fraction of the cost. Namely, the platform determines how much of the work is handled out of the box and how much of custom development eCommerce providers will need to do. Businesses can choose between DIY website builders, platform-based builds with customizations, and bespoke builds.
Of the three, platform-based builds with agency customizations are the preferred choice among businesses, wherein the cost is affected by the design of the storefront, the UX flows, the checkout and cart customization requirements, the product catalog structure, and the additional integrations pertaining to payment, shipping, and inventory. Here’s what to expect:
For bespoke and enterprise builds, the price can exceed $50,000 for the combined development effort.
On average, eCommerce agencies need between 4 and 7 months to build a fully-functioning, responsive eCommerce site. The work is divided into design, wireframing, web development, and marketing preparations. Here’s how long each phase entails:
Yes, the majority of eCommerce development projects come with additional costs for hosting, domain fees, premium themes or plugins, payment gateway fees, and third-party app integrations. In addition to the base fee for the B2C/B2B eCommerce agency, businesses also need to budget for maintenance, security updates, content uploads, inventory setup, and performance optimization.
While benefits related to inventory visibility and automated order processing can be seen almost immediately, considerable return on investment (ROI) can be experienced within 6 to 9 months after working with eCommerce companies. The value comes in the form of reduced manual order processing, better stock accuracy, faster order fulfillment, lower administrative overhead, and better customer service.
