Ramsdean, England—Really Simple Systems has upgraded both the free and premium editions of its cloud-based customer relationship management application with mobile access and integration with Kashflow accounting software at no extra charge.

Previously the company's free edition did not offer those tools. Customers using its premium edition paid extra for both mobile access and the Kashflow integration, but will no longer be billed for these features.

Really Simple Systems' free edition is limited to two users per company. Its premium edition starts at $8 per month and increases in price depending on the number of users and amount of data storage.
