The updates look very useful additions to the Mobile App, unfortunately as I am based in France I have found that Google Play does not allow the installation of the app. (something to install next time in the UK).
Without looking at the apps capabilities an area that I see that could be streamlined is the creation of a new client.
An operative is visiting a site to assess the work involved (issue an Estimate) or undertaking work ordered (issue an Invoice) for a new client. If there was some sort of “Welcome” SMS message / email sent to the new client with a link to complete their contact details which would transpose to the creation of a client record the issuing of the estimate/invoice would be a much easier process whilst still on site. Without this facility there are quite a few steps before being able to send the details to a customer.
An idea for you to consider as an additional feature.
