“Sentrien Systems was there for us when we decided to upgrade our Service Management software and needed to upgrade our accounting software with it. We were a little worried at first, with everything we had heard about the stresses of migrating financial data. But Sentrien really took care of us, and I was impressed with how well they knew the product. They answered all my questions and went over and beyond to make sure our system was working the way we wanted. Their patience with all my questions was amazing. This was definitely not an inexpensive project, but you get what you pay for and I’m so happy with the results! Thank you Sentrien!!”

“It was a little rocky at the start, our first meeting. They insisted on asking many questions that did not seem, at first, to pertain to our selection of an accounting system. As the process unfolded, we came to appreciate the reason for their very thorough discovery process. They alerted us to issues and functionality that we hadn’t discussed or considered. Our new system is a drastic improvement. The added tracking and reporting features allow us to report to our Board and Executive management on more KPIs and with greater detail and accuracy. Our accounting and finance department was trained well and our adoption has been very high. We are very pleased and have engaged Sentrien on more project work.”

“We needed to change our service management software, and we knew that would require us to change our entire accounting system, too. After ten years using our previous system, we had tens of thousands of customer records and hundreds of thousands of transactions. We were concerned about maintaining the integrity of our data, running our business during the cutover process, and fulfilling our new training needs. Not only were the folks at Sentrien knowledgeable about data migration, but they understood our industry and became our business coach through the entire process. The combination of their industry knowledge, experience, and understanding was evident right from the start. We even had some accounting issues prior to the migration, but they were adept, resourceful, and supportive enough to help us identify and resolve the problems prior to the migration. We couldn’t have been more pleased.”

Linda Couch, Chief Operating Officer

“Sentrien was referred to us by another contractor for the migration of data from our former software program to our current one. They did a marvelous job with the migration, which was challenging, but they went above and beyond to get it done for us. I will certainly recommend Sentrien to others. Their entire staff was a delight and made this daunting task proceed very smoothly.”
