Salesforce Review from Rishi Kumar
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.

Scott Milner's Review Sourced from Google
Jerry and his team are absolutlely top notch. Highly professional, diligent, and just really, really good at what they do. All of this shines through in the first meeting with the team. After thorough testing, they set a clear course for correcting vulnerabilities and for using best security practices in development. They then work with the founder and the development team to implement their plan. I really appreciated their mix of taking a dogged approach toward security while also being patient and explaining things in an understandable way with an extremely busy and no-so-technical founder.
