Many stationery shops stock well-known paper ledgers such as the Simplex D and the Evrite 707. There is also the analysed cash book to consider.
You will also find Collins and perhaps a few other systems. Pop into a stationer like WH Smith and see what is on offer. We have indicated the colours to look out for. The analysed cash book may be in a variety of colours, but the Cathedral range is bright red.
David Porthouse & Co have a free paper system which you may download by the quarter (every three months) and use. Once you are familiar with it, you can upgrade to an identical spreadsheet system, e-mail it back to David Porthouse, and then get a discount because he has a system which can read the spreadsheet electronically.
