Add one module without replacing everything else
CSS software can be licensed individually and integrated with applications you already use. Add Accounts Payable, Accounts Receivable, General Ledger or Payroll where your current system has a gap—while keeping the software and business processes that continue to serve you well.
Most modules can operate independently, and CSS can help connect transactions and information with your existing IBM i applications.
