To help daily tasks move along smoothly, Denali works with some helpful add-ons, such as payroll services, tax form services, dedicated server services, online backup services, credit card processing, barcode software, eCommerce services and specialty shop services. Unlike many other services we reviewed, Cougar Mountain provides credit card processing via Merchant Warehouse as an integration (not as an addition); you just need a merchant account. In term of banking integration, Denali can work with all common financial file types and can print checks, prepare deposits and pay bills via electronic payment.
