For over 35 years, Sumus has been building its story alongside some of the largest companies in Brazil, offering technology, intelligence, and trust to transform telecom cost management. We were pioneers in developing call accounting systems and have continued to evolve with the market ever since, without losing sight of what matters most: delivering real results to those who trust us.With this commitment in mind, we created Sumus TEM+, a solution designed to give companies more visibility, control, and savings when it comes to managing telecom usage and expenses.From this same journey, Sumus Concept was born — our complete and flexible SaaS platform. It brings together a range of modules and services that go far beyond telecom: process automation, facilities management, asset control, invoice auditing, ESG, digital signatures, cost allocation, and more. All developed to simplify workflows, speed up decision-making, and boost operational efficiency.Today, we are the largest company specialized in TEM (Telecom Expense Management) in Brazil. Our team combines technical expertise, strategic insight, and a close customer relationship to ensure smarter, more sustainable, and data-driven management.Since 2001, we have held ISO 9001 certification across all our processes, and our professionals are certified in ITIL and trained in PMI best practices. Technology is our foundation, but it's people who make the difference. At Sumus, we value expertise, listening, and continuous learning. We are driven by challenges, guided by results, and proud to build a place every day where innovation and recognition walk hand in hand.
