The Abacus SaaS (Software as a Service) solution provides you with an opportunity to obtain Abacus business software through a leasing subscription and use it directly over the Internet from the cloud. This then gives you access to your data whenever you want it, wherever you happen to be. The different Abacus add-ons (for financial accounting, accounts receivable, accounts payable, payroll accounting, CRM, invoicing, performance measurement, plant, PPS, AbaShop, e-business, etc.) can be used either individually or in combination with one another.
