Winkbill is a ‘simple online invoicing system’, which offers billing, contact management and online reporting to help you keep track of your financial flows. It comes with yer typical web service dashboard which in this case gives an overview of your invoice universe, and the interface is simple enough to be useful.

The UI is also full of Ajax cuteness, which means you should spend less time waiting for the page to refresh and more time getting on with your business. What I like most is the fact that the developers have resisted the temptation to offer loads of complex features, and have instead stuck with the basic customers, invoices stuff. It makes it easy to use which is vital.

The pricing ranges from free for up to 3 invoices a month, to $39.95 a month for up to 5000 invoices, which should be enough for many small businesses. Definitely worth a look if you’re in the market for something like this, although as with all online services I would counsel strongly that you keep your data backed up offline just in case the service goes unavailable for whatever temporary or permanent reason.
