Re: account package that can be tailored made to my needs
Take a look at Quickbooks; You can get a free trial of it. I got a free trial CD from Axonware.ie
I had a look at it and decided that it did not meet my needs, but when going through the set-up routine I definitely recall that there were options for people who are in sales, who have specific product lines and want to be able to have the ability to invoice each product on a product by product basis.
I assume that there are in total perhaps 20 newspaper titles. So it seems that it would be fairly straightforward to set up your accounts system with twenty product lines and 500 customers. How long it will take to enter the data I don't know, but this seems to be what you need to do.
I imagine that it should be possible to set up a monthly invoice as a 'repeat order' on the system - which would mean that as long as it does not change, you would not have to re-enter the invoice data each month
I am not an accountant or in any way expert in this area - It is just that I happened to take a look at the Quickbooks package. I expect it is almost certainly the case that other relatively cheap accounting packages will give the same functionality;
