customer onboarding in technicians app

Our technicians install the customer equioment, current new made an app that they can onboard a new customer, very simply it captures primary information,Geo data and we upload copy of their ID what is important as well is we cpture what inventory is allocated and sometimes inventory taken form an nactive customer and reallocatde to a new cusotmer so automation of that would also be nice to have it in the technicians app.
