We are in beta. While we learn, every club and small charity uses Shoebox free, subject to fair use. No card, nothing to cancel. About ten minutes with a year of statements to hand; your work is saved privately and you can delete everything with one click.
Your statements are stored in the UK and read only to build your accounts: what happens to them. Nothing is ever filed automatically.
Each club or charity keeps its own documents and accounts. Pick one, or add another.
