As a business owner or manager, it can be tiresome to have to enter employee salary details into the payroll software, and then manually enter it into the accounting system, too. Without integration between the different software, this will always be a thankless and time-consuming task. In duplicating data from the payroll software to your general ledger, aside from it being a lengthy task, there is also ample room for error, and as all good business owners and managers should know, errors can cost a company more than just money.
