Expert trades offer an excellent package to help the small business allowing a sole trader to offer customers a level of professionalism normally associated with larger companies. It's all very simple to set up with the minimum amount of time and easy to use on smartphone as you go along. You can create a 'live' invoice adding to it as you go and present your phone to the customer for card payments which I think is an excellent service. Yes there is small cost but it's marginal compared with time chasing payments. The support I have had from the team has been great as well. 5 stars all round from me. A very useful business tool.
