Does Unanet Support SQL Express (free version)?
As the System Requirements page points out – we do support that version, although we would not recommend it for anyone but our smallest customers who plan on limited use of the product.
It is difficult to say when a client may reach a specific size limit. How fast their database will grow will depend on how many features of the system they use, and include considerations such as: how many users do they have, how many organizations and projects, do they track at the project level or task level, will they be using planning and assigning, resource requesting, accruals, etc. One big impact to database size has to do with attachments (will they be heavily using expense attachments, project note attachments, etc.).
Should a client choose to move ahead with SQL Express, they will need to closely monitor their performance and database size in order to prepare for an upgrade with sufficient lead time should they determine it is needed.
