David Stewart

Online Merchant
"INSO’s service was very quick in picking up calls and also very adept at understanding our scripts and business model. The agents were better at our scripts and process when compared to other centers. We would definitely recommend their service to anyone who depends on good technical knowledge and understanding of customer needs to provide good service to any customer. "

Rudy Salar

Owner, Medical Appointment Processing Company
"We started using InSO's appointment scheduling service for over 1 year now and we are very likely to extend our contract. InSO by far has been the best center for us to work with. Their closing ratio is exceptional. We are finally able to see the ROI that we are happy about. Love to work with vendors who can make our life easy. We got several positive feedbacks from our customers thanking us for the wonderful customer care support. We thank InSO team for helping us out. If you are looking for the best support team for your company, then InSO is the answer. We definitely recommend InSO. "

Alan Cohen

Owner, Travel Company
"InSO was one company which I and my partner mutually agreed to work with. We are glad to make that decision. Four years of un-interrupted quality service. The level of service has never gone down since the day we signed. We have been working with the same project manager for over 4 years now who has been providing outstanding exceptional service. We love their support staff and can’t thank them enough for providing such an incredible service. We never had to worry about our customer service or sales support now. We know it’s all taken care off well."

Scott Miller

Owner, Nutritional Company
"When we think of InSO we are able to think of three things. Quality, Affordability and Flexibility. It’s rare to find call centers who can match all the three. After a long research, we decided to give InSO a try and we are very satisfied with their outstanding performance. They are very prompt in responding to our emails, promotional updates and marketing changes. Also we love their attention to details. Very well organized group. These guys know what they are doing. I definitely recommend InSO for all your business outsourcing needs."

"We have been using InSO for over 7 years now. I am extremely satisfied with the quality of support and the attention they have given to our business over the past 7 years. Our customer service rating significantly improved since the day we outsourced our customer service support. They have been very flexible with us and have always accommodated our last minute requirements and changes. I also have to thank their sales team for increasing our sales by 31% last year. We highly recommend their service."

"My company has been working with InSO International Call Center for over 8 years, and I am extremely satisfied with the dedication, skill and quality of the center's work. The reps are well-trained and provide excellent customer service and sales support. They've even turned my CS into a profit center by saving cancelling customers or upselling existing customers with new products. I highly recommend InSO."
