Reval is a treasury and risk management platform allowing users to manage cash, liquidity and financial risk. Developed by the company Reval, the software and company were acquired by ION in 2016.
Reval is suited to a large number of transactions across a disaggregated business. It may not be well suited where especially complex derivatives and highly stylized reporting are required.
They are usually prompt and reliable. Occasionally, we have time difference issues as support is often offshore some local staff turnover since ION acquired Reval, but this has been managed.
GTreasury acquired Visual Risk (which was an alternative product), but we preferred Reval for processing grunt (albeit GTreasury/Visual risk had an easier user interface). Have used Sungard/Quantum previously, however, I haven't looked at it recently.
