Recommended Hardware Settings For systems@work Software (Updated Jan 2015)

Hardware requirements for time@work and expense@work will vary considerably between clients. Factors such as whether or not Servers are dedicated and whether they are Physical or Virtual Servers will also have a significant bearing on the RAM and CPU requirements.

The following should therefore be considered as guidelines only:

Please note that the time@work and expense@work Maintenance Applications are not supported in a WAN environment. For clients who are deploying this architecture we recommend the use of Citrix or Remote Desktop / Terminal Server.

Up to 100 Users

WEB server:

CPU: Dual Core 2GHz or faster
RAM: 4GB Minimum (8GB Recommended)
HDD: 200MB Minimum
OS: Windows 2008, 2008 R2 (Standard or Enterprise), 2012
Connection:1-2 Mbit/s Upload (or faster) for Web Users.

SQL server:

CPU: Dual core 2GHz or faster
RAM: 4GB minimum (8GB Recommended)
OS: Windows 2008, 2008 R2 (Standard or Enterprise), 2012
SQL server: SQL 2008, SQL 2008 R2, SQL 2012, SQL 2014
Collation: Latin1_General_CI_AS
HDD: 20MB Minimum needed for default database
DB Size: Estimated at Max of 500MB Per Year

200 Users

For 200 users a minimum Ram on the IIS Server of 4GB is required. 8GB or 16GB is recommended.

400+ Users

For 400+ users a minimum Ram on the IIS Server and SQL Server of 8GB and a 64 Bit Operating System is required. 16GB or 32GB is recommended.

As general guidance we would recommend that you allow 100MB of RAM per simultaneous/concurrent Web user. Therefore if you anticipated up to 160 of your employees using the system at the same time then 16GB would be the minimum RAM we would recommend.


For clients using the Document Attachment capabilities of time@work and expense@work it is important to ensure that appropriate storage is available depending on the file types and frequency of upload.
