I don't know what your computer skills are like, or how knowledgable you are with spreadsheets, I use Excel.
I designed my own, each days work is listed, it is a printable sheet with all relevent details, customer name, price and 2 columns where I can tick paid or collect, plus an auto total column under the prices.
It's easy to add to or delete from, once you have spent the time designing it, it is then a simple case of copying and pasting the template.
To one side of the round list I have the invoices for the accounts, as I have a commercial round, this bit is essential.
I no longer need to print out my work lists, I know them all by heart of course, so I just print the invoices. When I was contracting the work out I printed out the lists as well, then the guys working for me would simply fill out the form with ticks or crosses, idiot proof (it needed to be!)
Tried to copy and paste an example in here, shows the text of course, but not the design and pattern. didn't think it would though!!
