Like any other business, micro-businesses have a requirement to properly manage their sales process by utilising a sales management/CRM system. Most recently I discovered a free internet based CRM system (for 3 or less users) which does just that. This application allows you to manage your clients, differentiate between leads, prospects and potentials and allocates a weighting for where you are in the sales cycle. It provides a graphical view of your sales funnel and projects the value of sales you expect to close this month and next. It allows you to manage marketing campaigns and a bunch of other sales related activities. Just because you're a freelancer doesn't mean that you can't apply the same discipline to your business as a large firm. Take a look at www.zoho.com/crm. Lovely stuff!
