Membership services provider Associa has launched a management system to handle membership databases and subscriptions.
Charity Manager will contact members annually to encourage renewal, draft and issue reminder letters, collect membership fees and process Gift Aid returns.
Charities can access their member database via a secure internet connection.
The service costs £1.80 per member per year.
Jan Rogers, business development manager at Associa, said: "Until now, charities have either had to invest time and money into managing their membership, or look for a high-cost, tailored, outsourced solution."
Associa provides services for the National Farmers Union and the Macular Disease Society.
