Charities could "go to the wall" because they can't fill important IT vacancies, and are losing out on donations as a result.
The warning comes from recruitment consultancy the Principle Partnership, which says that charities are too reliant on specialist fundraising technologies.
Relationship management and database systems, such as Blackbaud's Raiser's Edge and Westwood Forster's Visual Alms, require expensive staff training which many charities can't afford. As a result, many vacancies are not filled.
Kit Gatrell, consultant at the Principle Partnership said: "It's a very serious problem. One of our clients, a large charity, took more than four months to fill a single role. And with training costing up to £350 per person per day, this simply isn't an option for many voluntary organisations... if the situation continues, we could see a lot more charities going to the wall."
