System Requirements

Providing our customers with the best user experience is important to us and we constantly strive to make Clarity Software available to everyone. The more powerful the specification of your computers, the more likely you will achieve an optimised level of performance from your Clarity system. We would be happy to discuss your infrastructure with you at any time on +44 (0)121 248 2448. The following information outlines system requirements to ensure you get optimum performance when using our software.

Third party software integration

If you have any questions about the extent of integration for supported versions or upcoming versions not shown on this page please contact our sales team who can provide you with more detail.


  • Microsoft Office 2010 to v2016 (2016, 64-bit and Office 365 versions require Clarity Desktop v5 or above. Office 365 integration still requires a desktop client)
  • Google Chrome, Firefox or Safari (Only on Mac O/S)
  • Sage 200 (2011, 2013, 2013 R2, 2015) *Desktop versions only.

  • Xero accounting software (requires Clarity Go)
  • QuickBooks 2008 to 2017 (Pro, Premier & Enterprise) *Desktop versions only.

  • Sage Line 50 Accounts (Inc. Sage Essentials) v8 to 2018 (v25) (Sage Drive not supported) *Desktop versions only.

  • Intel i3 (or compatible) Dual Core 3GHz processor
  • 8GB of RAM
  • 20GB of available hard-disk space
  • 20GB of available hard-disk space
  • 1920 x 1080px screen resolution
  • Access to local or network printer
  • An internet connection on at least one client machine

Notes: 1. While Clarity is built for Microsoft Windows, it is possible to run it on a Mac by using Parallels, Boot Camp or similar software which provides a Windows environment on a Mac. You will require a copy of Microsoft Windows to install within this environment.
2. We do not support Windows XP or Vista. We also no longer support Clarity Pro\Lite pre v4.3.x.x and there will be no further development of Clarity Pro\Lite v4.

As part of deploying your Clarity system, the database and server software will require a dedicated server machine at the customer site, with a stable and permanent internet connection. This server machine should meet or exceed the following specification:

  • Intel i5 (or comparable) Quad Core 3.3ghz processor
  • Microsoft Windows 7SP1/Server 2008 R2 to Windows 10/Server 2012 R2 – Updates and services packs should be up to date
  • 16GB of RAM
  • 50GB of available hard-disk space
  • 1920 x 1080px screen resolution
  • For the Clarity database – Microsoft SQL Server Express 2014 onwards
  • Existing systems using SQL 2008 R2 up to and including SQL 2012 are still supported

Notes: 1.Please note that Microsoft’s SQL Express database engine (free version) has a maximum storage capacity of 10GB and is restricted to using a single core within the process and 1GB of ram. Clarity’s performance will be significantly impacted if your database reaches 10GB. Once your database reaches 10Gb you will need to upgrade to full SQL Server. We are unable to advise on the best CAL (Client Access Licence) to purchase as this is down to your individual requirements.
2. It is possible but we do not recommend using a server that already has Microsoft Exchange installed on it. If this is the case, please discuss with the Clarity support team first. Any server that is already under load, regardless of software installed is not recommended.
3. SQL Server requires database files to be stored on a local drive. Network drives are not supported without use of a Storage Area Network (SAN).
4. As part of the implementation of Clarity Pro we will setup a nightly backup of the Clarity database using a scheduled task. These backup files will need to be manually backed up to an external location or added to your offsite backup routine as we do not hold copies of these.

  • iOS 9.0 or above
  • iPhone 5 or above
  • iPad 2 or above (iPad 3 is known to be slow due to upgraded graphics, without supporting hardware being upgraded)
  • Android devices running OS 4.4 or above (except Sony Xperia Z3 which is not currently supported)
