Circle produces a complete Point of Sale, stock management and online sale solution for booksellers. It is ideal for bricks and mortar stores that want to be online, but don’t want the hassle of managing a website and the shop floor independently.

With Circle, all sales (in-store or online), are managed through a single cloud based system that is accessible from anywhere, like your online email account. It knits with your existing business systems for email, accounting and eftpos and functions on any device.

Circle is backed by leading international innovators and software companies such as Yikebike and Acclipse and has established partnerships with Nielsen, Xero and Thorpe Balker. It is used by the majority of independent booksellers in New Zealand and a growing number in Australia. A resourceful and dedicated staff of 7 is backed by a group of 5 shareholders who are all founders of significant local software companies in their own right.

Circle has been operating for over 15 years under the managing direction of founder, Warwick Schaffer.
