CiviCRM is a powerful tool that could be really useful for many non-profits in Mexico.
Unfortunately the community is very small in my country. I hope that in the next years the community expands around Latin America.
The CiviCRM community is a great place for support, to exchange ideas and to contribute back. Working with other developers or users has often allowed me to pool our resources together and lower our costs, while ensuring better quality since there were more people using it.
We feel there are too many obstacles facing not-for-profits (NFPs) considering commercial CRM offerings, including many of those that are charity oriented. From licensing models which restrict the fluid expansion of an organisation's user base (why should you be punished with higher costs for being successful?), to support from commercial companies being inherently tied to one supplier; a NFP would benefit from the option to 'shop around' for those most appropriate, e.g. based on: proximity and availability on-site, cost, experience, value added services... They also often lack the capacity for charity relevant workflows, necessitating either customisations, complicated and inefficient workarounds or an en-masse call for new functionality, as individual charities do not appear to carry the weight required to influence subtle NFP-only changes to market leading software, without large expense.
On the flip side, CiviCRM is completely free and open-source, carrying with it a friendly, hard-working and enthusiastic community of developers and implementers, constantly listening to the users' needs and sculpting future releases to the requirements of NFP organisations. This is exciting!
We use CiviCRM for our Membership and Supporters system. We're committed to using Open Source solutions and are keen to expand the variety and success of our member recruitment and fundraising efforts.
CiviCRM is a powerful tool for NFP's - small or large, rich or poor. The ease of customisation, huge feature set and great support forums make it possible for me to provide my organisations with exactly hwat they need.
