We are a large purchasing co-operative having 1000+ suppliers and 450+ members. Medullus Systems has been our software development partner since 1998 and in 2007 they were commissioned to develop an end to end ERP and ledger system for the company. It was a very successful mult-year project, delivered on time, on budget with not even 1 day of disruption! We recently merged with another buying group and this system was a key component in the merger decision. The system scaled very easily and automatically as we doubled our membership and vendor base in 1 day! Medullus was there all the way to support us during this integration.
