I like that it is very easy to use and has many features including but not limited too; Estimating of both fixed price or time & materials contracts quoting with breakdowns into categories such as labour hours cost etc., Contractor quotes which i find important when dealing wtih other tradesmen - they tend tio make up their own mind without checking my quote first! The only dislike would probably have been if we had used this product before moving over to Xero (our Accounting software) so perhaps there could maybee more integration between systems?
