Mainstream Fund Services
“Pacific Fund System’s PFS-PAXUS is a world leading specialist accounting and administration application system designed specifically for use in the alternative fund administration industry. At Sanne we chose PFS-PAXUS due to the system’s ability to deliver an integrated solution offering a straight through processing solution for our functional teams. PFS-PAXUS integrates all parts of the administration process that traditionally had to be done on separate systems, incorporating the securities portfolio, allocation system, general ledger, fee calculation and share registry module into one operation. For Sanne, the benefits are clearly visible, in the ability to perform complex fund valuations in a simple and automated fashion, allow us to meet the needs of our clients while reducing not only our risks in calculating NAV’s but our IT overheads as well.”
