Excel is not a donor management system!
Your database is one of the most valuable assets for your organization. A good database is necessary to help you grow and provide better services to the community. It should support the organization’s mission and should be adopted by your entire organization and not only one team. It should be easy to use (you don’t want a system that only one person within your organization can use), flexible (it should evolve with your strategy) and it should support the type of work you do.
