Claim season is when the spreadsheet usually fails
Most church Gift Aid trouble is not the 25p arithmetic. It is the week you try to reconstruct who gave, whether they had a live declaration, which fund the gift was for, and which cash collection might count as a small donation. The spreadsheet was a memory aid for a year of Sundays. By March it is a second job.
If those facts live in the giving flow and the service close, you are not building a year-end workbook from bank lines and paper slips. You are exporting what the year already recorded.
