Example with sample data
Contract, install, interconnection
Collect the deposit on the signed proposal, then send the install milestone and the final one after the utility approves interconnection, each as its own invoice on the project.
InvoicingPanel upgrades approved first
If the site visit finds the main panel too small, revise the proposal and the homeowner signs the upgrade before the crew orders it. Its lines then sit on the project.
Estimates and e-signaturesThe system on record
Inverter, panels and battery go on the customer as one system, recording each serial number, the install date and the warranty end, ready for the service call in year six.
Customer recordsInstaller hours against the bill
Installers log their hours on the project and permits go on as expenses, so you can see what an 8 kW job really cost before the last milestone is paid.
