Microsoft Retail Management System HeadQuarters (HQ) operations do not require dedicated, expensive, high-bandwidth phone lines. Instead, its data communication incorporates smart algorithms to economically compress and transfer data between the head office and retail stores. These minimal bandwidth requirements let you exploit low-cost, dial-up phone lines and the Internet. You can use a virtual private network (VPN) to securely transfer data via the Internet between the head office and retail stores. This network can easily accommodate simultaneous connections to hundreds of stores

Each remote HQ Client sends information from its store's database via the Internet, virtual private network or dial-up access to the HQ Communications Server. It automatically initiates a connection to the head office per a schedule you specify. Then it updates stores' databases per your directions in HQ worksheets.
