“Every bit counts, even if you’re leaving behind $500,” says Rick Cohen, National Council of Nonprofits spokesman.

“It can make a big difference for a nonprofit, especially if it enables a nonprofit to take care of some general maintenance, something they have been putting off for years,” Cohen says.

“It’s the reality of so many nonprofits to keep overhead low,” he says.

Roof repairs, he notes, fall under “overhead,” yet can be essential in continuing to provide services.

“So many nonprofits are focused on helping people, helping animals, (supporting) the arts — basic infrastructural needs can go unfilled,” Cohen says.

For instance, he says, nonprofit dollars make necessary stretching out the life of a delivery van as far as it can go, rather than replacing it.

“Every penny counts and is greatly appreciated by the nonprofits, and indirectly by the people they are supporting every day. It’s not about the organization. It’s about the people they help,” Cohen says.

“We encourage people to do what they can for a cause they care about,” he says.
