Intuitive, good pricing and cloud- based

The simplicity and the layout. Also the fact that it offers separate sections for receipts and suppliers, while most online invoicing software completely skips receipts. Over the years the price has remained between £12 and £18, with a few ups and downs, so overall very affordable for the offering. Invoice generation is simple, although you can only choose from a few templates. Recurring invoicing is also included in the price. It also integrates with PayPal, so any purchases made that way can be automatically pulled into KashFlow, and with a click of a button you can get the expenses receipts created. Over the 10 years that I've used it for, there were only a few minor outages, that very always very quickly resolved. Can't really comment on support as never needed it.
