Open Systems is offering a promotional program to offer purchasers low-cost lease payments. End user buyers must sign with Open Systems Financial Services by July 31 to qualify for a $50-per-month rate that is good until next year for financing purchases of Traverse or Open Systems Accounting Software. The leasing services were launched by Open Systems earlier this year and are also available to finance third-party expenses such as hardware, training, implementation, and services. After this year, payments are stepped up to the full level.
