It obviously may not be possible for your specific business but if it is I'd encourage you to try and arrange things so you don't have to invoice people at all.

For http://comfypage.com http://comfypage.com we have a small set of additional services we can provide. We used to invoice people but these days for most stuff people fill out a form and pay online then we get an email that says "person X wants Y done" No invoicing required and we get paid up front so there's no chasing payments involved. We're probably losing a percentage of customers who don't like this process but the amount of time we spend on admin tasks is basically zero.
