QuickBooks Web Connector is an interface that helps to pull the information from third-party web-based applications as many companies do use industry-specific solutions for estimates, invoicing and some other stuff that caters their business requirements. I have seen companies using some applications for years even before implementing QuickBooks. The legacy applications in most of the situations do not offer and cater the accounting requirements of a business and obviously, the accounting people can’t afford double-entry in two different applications flawlessly that too after devoting extra time and effort and this is what makes QuickBooks Web Connector a significant component.
