The salesforce foundation offer all charities a full version of salesforce with customised screens to meet your requirements, and ten free licences.
We have seen over the years many charities try to implement this but fail as the potential complexity of salesforce overwhelms the project.
ExcluServ have tamed salesforce to make it deliver those basics in an affordable low risk project. We can be sure that you will have a fully functioning database within weeks.
As salesforce is enterprise level software, the potential for it to then grow over time is still there, and we will partner with you to continue to add more and more value.
