What is QuickBooks Web Connector?

quickbooks web connector

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.

QuickBooks Web Connector works on SOAP (Simple Object Access Protocol) – A web-based service Interface. On the other hand, QBWC (QuickBooks Web Connector) can automatically sync and pull the information into QuickBooks as per the defined schedule or simply be run as per the requirements and suitability of Users.

QuickBooks Web connector works with QuickBooks Desktop and QuickBooks Point of Sale. QB Web Connector is an XML file, which was designed to create an intermingle bridge between QuickBooks Desktop products and the Web applications. QBWC is supported by QuickBooks Desktop Enterprise, Premier and Pro later than 2016 and QuickBooks Point of Sale V13.0 and later and same applies for the Canadian and UK Editions as well. It is easy to configure to sync with the web-based applications and import the information.
