Gift Aid records can be kept in paper form, on computer using spreadsheets, eg Excel, or using a commercial Gift Aid software programme. Some Gift Aid software programmes are enabled to claim direct with HMRC, once your church is registered with Charities Online (which you only need to do once).
The software highlighted on the Parish Buying
website for recording and claiming Gift Aid and GASDS is Data Development's Donations Coordinator. In fact, more claims have been made direct with HMRC using this software than any other. See link in panel on the right.
