Phone Answering Services Review from Mandy
I’ve relied on Nexa as my primary answering service for customer calls, and they’ve been outstanding. Their after-hours and midday telephone answering services ensure no call goes unanswered, providing incredible convenience and ease of use. The team’s effective communication and excellent virtual receptionist service have consistently impressed me and made a real difference in managing customer interactions.

Jessica Michalak's Review Sourced from Google
Was recommended Nexa for an after-hours answering service and things seemed fine until they weren’t. One of my colleagues noticed we hadn’t received a call summary in a while, and we eventually found out they hadn’t taken a single call in over TWO months. When I called to ask why calls weren’t being forwarded, and why we were never notified, I was told they “have too many customers to keep an eye on each one.” Despite this, we were billed every month, even though they didn’t answer one call. I was told a supervisor would follow up. No one ever did. Our IT team confirmed multiple times that it wasn't an issue on our end but that was what Nexa claimed it to be. After sending two additional emails with no response, I finally emailed to cancel. Only then did I hear back, receiving a cancellation form and a generic “sorry to see you go.” Don’t waste your time. This is not a legitimate answering service if customer support is essentially nonexistent.

Big Shoutout to Jason Shouldice at Call Center Doctors! We've tried leads before and got nowhere. Were closing at nearly 50 percent with them. Definitely worth the investment! I highly recommend Call Center Doctors! Below is one of the roofs we got through Call Center Doctors! It really works!

I’ve tried a lot of different lead generation companies for my roofing business, and Call Center Docs has been the best by far. The leads I get from them are real, solid, and actually turn into jobs, not just random calls or bad info like I’ve gotten elsewhere. It’s been a huge difference for my business, and I can honestly say they’ve given me the highest quality leads I’ve ever worked with.

Our small clinic in Texas was struggling with billing and insurance claims. Invensis’ Revenue Cycle Management services turned that around quickly. Claims are processed faster, and denials have decreased. They're professional, easy to work with, and understand the U.S. healthcare system inside out.

Sarah Carter's Review Sourced from Google
Starting a restaurant is overwhelming, but having a professional website that actually works for your business makes all the difference. The team made the process so easy, they took my vision, gave expert recommendations, and built a beautiful, user-friendly site that showcases our menu, takes reservations, and even helps with online orders.I was worried about the tech side of things, but they walked me through everything and made sure I could manage updates on my own. The best part? We started getting customers through our website almost immediately! If you're launching a restaurant and need a site that actually helps you grow, I can't recommend them enough!
