The Value of a Partnership with TMC

TMC uses a proven methodology for successful implementations and shares Microsoft’s commitment to create a long term relationship with our clients. The result is a faster, better, more predictable implementation for your business, with little disruption to your business operation. At TMC, we’ve learned that immersing ourselves in our client’s business and understanding their problems, goals, systems and processes is key to delivering an outstanding business solutions software implementation. We look at a company as a whole entity. We listen carefully. We ask pertinent questions. We collaborate with our clients at every level, and we never stop working until the solution provides optimum performance throughout the organization.

TMC is rigorous with our approach to ERP implementations.  Following a defined project methodology, we strive to deliver a consistent result with the highest levels of customer satisfaction.  Your project team at MINIMUM will include: a Project Manager who defines the project tasks, scope, timeline and then efficiently allocates resources; an Application Specialist who provides customized training, assists with data reconciliation, and post go live support; and a Technical Specialist who creates customizations and data integrations, and modifies reports.

The members of TMC’s consulting team are experienced professionals and originate from diverse backgrounds. Many are CPAs, MBAs, Accountants and/or past Controllers and CFOs. This unique combination of software knowledge and practical business application has proven to be a winning success. TMC will help you stay on time, on budget and focused until you reach that end objective.

Technology Management Concepts empowers clients to succeed with technology. We provide full training at implementation and continuous training and support as well. Long after implementation, TMC remains a part of your team, always available to assist as much or as little as necessary. We feel truly connected to our clients’ businesses, and our consulting relationships with clients are long and enduring. In fact, many of our clients have been with us since we opened our doors in 1984.

TMC isn’t just a vendor, or just a consultant. An implementation with TMC is a collaborative partnership.
You’re not just buying a software package. You’re choosing a partner.
