If you run a small business, you will be getting the above items all the time. But how do you organize them? I've never had a system to deal with this. Imagine you have 5 of each in your Inbox. You process them. But as I process each item, I want to know where to put it.
Do I have a folder for all my Invoices grouped by month, so they are easy to track when doing accounts? Or do I group by Supplier, but then you might have one off suppliers with a near empty folder all to themselves?
Your thoughts on best practice?
