Designed to be integrable with the rest of the tools or third-party programs you use, QuickBooks allows management and tracking of incoming expenses or revenue, can be used for both invoicing and payments, and is the best tool available if you want to move some of your bookkeeping tasks from the offline medium to the cloud. Can you manually perform many of the functions that are possible with QuickBooks? Sure, but it would take more time, and the productivity of your staff will be affected.
