The real bonus with PlanSwift is that for a one-time-fee you own a licence for the software. As the authorisation to use PlanSwift relates to the licence – you can move the licence from PC to laptop and back again once the software is loaded on the machine which allows you to bring the software on the road when required at no additional cost. Also if your data is kept in Cloud backup (e.g. Dropbox) then you can access your projects where ever there is a connection to the world wide web.

As the company is based in the USA the pricing is in US$. As a guide the following approximate Euro currency conversions will show you what excellent value PlanSwift is at – €845.66 EUR to purchase a licence outright with no recurring fees.
