⚡️ JOBBER SPARKY GROUP for electricians⚡️

We are implementing flat rate for service repairs and trying to extend to other services as time goes on. Right now to price out bigger jobs that we don't have flat rates for (or haven't been able to nail down a price) we have a spreadsheet with material and time and manually work out the project and then just input into jobber as a single line item. 

Wondering how other electricians are tackling more complex quotes within jobber without outside documentation?
