eCommerce Development Review from Parker Green
We initially engaged Digital Insides to get to a particular milestone when we were only about three weeks away from a deadline. They helped us create specific components in the project; we worked on a few while they also worked on critical elements of the site: a blog, a media gallery, a library, and an audio podcast module.
Those components were in a particular section of the site; they were utterly siloed in that section. Digital Insides also had to create the APIs to talk to the WordPress backend. Overall, setting up the web was the main scope of work.
Digital Insides created their development environment and developed all the components. Once they tested everything, they sent us the code. We already had the design layouts for them, so they didnt have to worry about it. However, we didnt have a mobile layout, so Digital Insides worked on that themselves and adapted it to the rest of the site.

eCommerce Development Review from Kelly Johnson
Since partnering with Bilberry, we have seen a marked improvement in our websites stability and performance. Their team manages our backlogged issues with such efficiency that our monthly development spend has actually decreased. Estimates are consistently accurate, and we appreciate their proactive communication; if a projects scope evolves, they provide an updated estimate for approval before moving forward. Our monthly sprints are now seamless thanks to their reliable planning and ability to scale resources rapidly to meet even the tightest deadlines.

Web Development Review from Adam Ely, PMP
As Director of Operations at Sands Investment Group, I partnered with Bilberrry to lead the redesign and rebuild of our website, enhance our marketing operations, and streamline internal workflows. We chose Bilberrry for their strong technical capabilities, cultural alignment, and outstanding reputation.
The project followed a well-structured four-phase process: discovery, design, development, and launch. From the beginning, Bilberrry took a strategic and collaborative approach, conducting workshops and technical audits to define a scalable architecture and intuitive user experience. Their team went on to create custom designs for more than 20 pages, build a flexible design system, and ensure the site met key standards for SEO and accessibility.
On the development side, they customized a robust content management system tailored to our needs, incorporating dynamic listing features such as saved searches, email alerts, and early-access content for select users. The new site also connected seamlessly with our internal tools, enabling greater efficiency and automation across teams.
The impact was immediate and significant: we saw a dramatic reduction in manual processes. Our team is now better equipped to manage content independently, while the platform itself is built for long-term scalability and performance.
Throughout the process, Bilberrry was responsive, professional, and incredibly easy to work with. They communicated clearly, incorporated feedback quickly, and consistently brought thoughtful, strategic ideas to the table. Bilberrry's unique blend of strategic insight, technical depth, and design acumen made them an invaluable partner in creating a high-performing, visually polished digital platform tailored to our business.

Small Businesses Website Development Review from Jarrell A. Green, MBA-DA
AutomateNexus built our entire e-commerce website for KourtLit from scratch. We sell portable pickleball court LED projectors and needed a professional storefront that could handle orders, inventory, and customer communication.
They delivered a modern, mobile-friendly site with a smooth checkout flow, backend database for order and inventory management, and automated email sequences for order confirmations, shipping updates, and follow-ups. They also set up our SEO foundation so we're positioned to rank for product searches.
What stood out was their BYOK approach we own everything they built. No recurring platform fees, no vendor lock-in. They finished the entire project in July 2025 and handed it off with full documentation and training.
If you need an e-commerce site built fast and built right, these are the people to call.

AI Development Review from Arionne Patterson M.S.
We hired AutomateNexus to build a new website for our boutique travel agency, and they delivered far more than we expected. Erin and the team built us a custom website, client portal, and admin dashboard from scratch plus set up automations that completely changed how we run the business.
Before working with them, we were drowning in manual tasks: sending confirmations, chasing documents, following up with leads. Now most of that runs automatically. The client portal lets our travelers access their itineraries and documents anytime, and the admin backend makes managing bookings so much easier.
What impressed us most was the strategic thinking. They didn't just build what we asked for they helped us rethink our entire workflow and showed us where AI and automation could save us time. We're saving 15-20 hours a week on admin work we used to do manually.
Communication was excellent throughout, delivery was on time, and the final product exceeded expectations. If you're a small business looking to modernize your operations without getting locked into expensive monthly software, I highly recommend AutomateNexus.
