"I have been using SliQ Tools for a few weeks now. It's a real joy to set up, easy to use and gives me absolutely everything I need for invoicing my 3 different business activities. Invoicing was always such a pain, especially when trying to keep up with recurring invoices. And of course the PDF email option is a superb time-saver as most of my clients have email accounts. Just brilliant!"
