      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.

      Mobile App Development Review from Malik Boyd

      Chop Dawg helped us turn our gifting app concept into a working prototype, handling wireframes, UI design, coding, data storage, and automation from scratch. Their team has been transparent, proactive, and highly responsive throughout the process. They provide clear schedules, flag issues early, and keep us informed at every stage. We’ve been very happy with the prototype so far and are excited to move into full iOS and Android development.

      Chop Dawg took our iOS app from concept to launch, handling design, development, AWS, and App Store requirements. Their team was responsive, practical, and highly supportive throughout the process. They also stayed involved after launch with updates and fixes, and even helped promote the app through their network. Their support contributed to strong early growth and helped position the company for a later acquisition.

      Web Design Review from Anonymous

      Chop Dawg supported us with UX/UI design for a new fintech web application. They took the time to understand our users, product requirements, features, and overall vision before moving into design. Over a 6 to 7 week engagement, their team shared regular Figma reviews, incorporated feedback quickly, and stayed highly responsive. They finished ahead of schedule with no budget issues, and the internal response to the final designs has been very positive. Their attention to detail, professionalism, and ability to keep the process organized made them very easy to work with.

      Mobile App Development Review from George McKerrow

      ELEK+RIK has worked on improving our React Native mobile app. We had the skeleton of an app, but they were able to do an end-to-end re-design of each of the main pages. Since then, they`ve successfully implemented around ~20 different features on our mobile app. We share a spec and design, they provide an estimate and occasionally some design options, then when completed create a PR on GitHub. Their code is well-organized, easy to follow, and rarely do we have to go back-and-forth about bugs. They are also excellent communicators - carefully following threads on Slack, effectively communicating design and engineering tradeoffs, and even producing a 10m Loom video walking through a diagram. Their communication is top-notch. They are super easy to work with even though we are on very different time zones. And, I am impressed at the speed and execution of their development.

      I had the opportunity to work with Accenture on implementing Salesforce with ServiceMax. Their expertise and dedication were impressive. Accenture's work on implementing Salesforce and the ServiceMax managed package was invaluable, significantly benefiting our organization's operations and efficiency. However, one area for improvement would be the documentation process. It was challenging to access comprehensive documentation, which slowed down certain aspects of our project. Nonetheless, I recommend Accenture as their talented team delivers exceptional results.

      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.

      Definitely recommend! Integrated has been our most reliable partner for the last five years. They designed and deployed our dispatching software from scratch, followed up, and addressed all the concerns we had. They are also handling our marketing and providing all other IT support we need. Bryan is very well-rounded and trustworthy! I wanted to give them a sixth star... but Google came up short.

      Integrated IT solutions have exceeded every hope and expectation! In partnering with them to create a Web platform for my agency's 25 employees to use, not only has my workload and stress been reduced, but the platform has received raves from my employees, who love using it! I can now dedicate more time and energy towards increased growth of my agency instead of tedious paperwork. Thank you to Bryan and the whole team, they never disappoint!

      Working with Shawna at Intention Labs was amazing. We worked together on a website optimization project for my business. The results have been nothing but stellar--the site is more organized and converting way better than it was before. Additionally, Shawna is just a great person to work with. She has amazing ideas, she is so thorough with every detail, and she is just pleasant all around. I got really lucky finding Intention Labs and I think anyone who has the opportunity to work with them would feel the same way.
