Hello everyone , I wish to setup an ISP business that will have branches in 4 cities, with a billing system to manage internet users and their data (user name password and usage). What accounting software should I implement to manage complete branches expenses to run company accounts smoothly so end of every month I am able to know where the company stands and manage also mange accounts in the 4 cities. What accounting software should I use centrally to manage the company? Pleas recommend a good ISP billing, accounting and invoicing software and why do you think it is the most suitable.
