If you’re like me, then invoicing is simply a way of life and you adapt to the needs of your clients. Some like spreadsheets, others prefer paper, while others still would rather use some kind of invoicing system. If you have flexibility enough to choose what you use to handle your invoicing in any way you see fit, then I have some options you might be interested in.

InvoiceMore – I had to start this out with a relative newcomer. With both free and paid plans available, InvoiceMore presents a strong option for those who are looking to simply create and send invoices while anticipating payments via PayPal (standard payments). The UI is brain-dead simple to work with. Overview, Invoices, Recurring Items, Payments, Notes… all tabbed like folders. The free version gives you three client slots for invoicing.

ronin – ronin uses the same principle as above, providing both free and paid plan options. It also presents a great UI as follows: Dashboard, Clients, Projects, Recurring, Estimates, Products, and Staff and Contractors. Other goodies include a live timer for project tracking. Based on what I was able to determine, however, you have to use a paid version to accept payments. But by the same token, ronin provides a lot of functionality that InvoiceMore above doesn’t.

BambooInvoice – Want something with open source going for it? Then take a gander at BambooInvoice. It seems that during the course of this roundup, the demo invoicing system was down. Worse, it doesn’t really provide any screenshots, either. On the flip side of this, you are able to run BambooInvoice on your own server, the way you want. So it’s free, and the ability to run this as you see fit is completely up to you. I’d love to provide you with a feature list as this sounds like a good deal, but sadly there isn’t one.

You get what you pay for?

This was among one of the first things that I thought of. Perhaps the biggest concern here needs to be that we get what we pay for? The reality is that the options above with a paid feature want you to convert from free to paid, so they’re going to do right by you. As for the open source solution, despite its complete lack of information, you’re the host, so you get to be in the driver’s seat.
