What is the difference, please
While they are both cloud accounting software services, they're quite different in a lot of ways.
Firstly, Reckon Accounts Hosted is a more mature software in terms of its features and functionality. Its based on our Reckon Accounts Enterprise software but with the added benefits of the cloud ie. you can login from an internet browser on any PC. Its more advanced and its features cover a broad spectrum for small to enterprise level accounting software requirements.
Reckon One is the newer kid on the block and its a new cloud service built on newer technology and is super affordable along with being customisable in terms of features through the addition of modules. While its not as rich as Hosted in terms of functionality for larger businesses, its an awesome solution for small business and is continually evolving.
Each software has its own way of doing things so my recommendation to you would be to give each one a test drive by taking out a free 30 day trial and see how it works for you and your requirements.
I'll add some info below on each software service and a couple of videos as well -
