The first successful U.S. micro-donation effort may have been in 1891 when a Salvation Army captain put a kettle out on a San Francisco street and collected donations to fund a Christmas dinner for the poor. Micro-donations have morphed in many ways since then, involving small-sum donations made via checkbooks, credit cards and, in more recent years, website links, text messages and other “new technology” tools.

How successful your charity will be in following the micro-donation tradition depends on many factors, including the economy, marketing ingenuity, ease of making donations and security controls. Here are four suggestions for making those small potatoes add up.

Many nonprofits depend on the funds raised at an annual gala, conference or other special event to keep their organization in the black. But successful events require a careful balancing act. You need to keep a tight rein on expenses, yet attract and entertain as many generous supporters as possible. Here are some ideas for maximizing revenues.

Nonprofits have pursued corporate sponsorships for years, with good reason. Effectively executed, sponsorships can benefit both sponsor and organization. But if your nonprofit isn’t careful, a sponsorship can be deemed paid advertising and your organization could end up liable for unrelated business income tax (UBIT). Although the Internal Revenue Code includes an exception from UBIT for certain sponsorship arrangements, navigating the rules can prove tricky.
