Who we are and what we do

Much has already been described about the special character of Trinity Management Systems GmbH in the sections "About us" and "Our values".


As an owner-managed company, we are able to determine the goals of our actions ourselves and do not depend on the guidelines of external investors. The most important target group of our activities are existing and future customers, whom we would like to equip with software solutions that facilitate the fulfilment of their tasks.


Trinity develops, distributes and maintains the Treasury Management System Trinity TMS, a modular software for the professional financial management of companies.


Our customers are companies of different industries and sizes who want to know, with the help of our web-based software, which liquid funds they have available in which currencies at which location in the world in the next days, weeks and months.


For their decisions on financing and investments, they need a reliable basis of current, complete and correct information. This is made up of account balances and payment flows that are centralised in the system.

For this purpose, Trinity TMS offers numerous modules and functions for daily cash management, short-, medium- and long-term financial planning, the management and valuation of financial transactions (e.g. loans, cash investments, foreign exchange and interest rate hedging transactions) and for reducing the associated risks (e.g. liquidity, default, foreign exchange and interest rate risks).


The solution has been running reliably for years in the private cloud or on-premise in third-party data centres and is constantly being further developed by us. It has to be adapted to new requirements of our customers, the market, legislation, but also to new technologies. The solution must be presented to potential and existing users, implemented and later maintained or even expanded.


This results in many interesting career opportunities at Trinity for experienced professionals and those who want to become one. In our international team of experienced experts, we offer plenty of room for independent action and innovative, goal-oriented solutions. The fields of activity are varied and challenging. You can rely on our colleagues and they are happy to help each other with problems.
