Milestone invoices for installs

Solar invoicing software

Solar invoicing software for residential and small commercial installs. The deposit is paid with the signed proposal, the install and interconnection milestones each go out as their own invoice, and the finished system goes on the customer's record with its warranty.

Example with sample data

Free contractor invoice template

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.

Invoicing

Panel 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-signatures

The 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 records

Installer 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.

What solar installers ask about milestone invoices

Is there invoicing software for solar installers?

Yes. Proposals, projects and milestone invoices live together, with each system saved on the customer.

Can I bill solar projects in milestones?

Yes. Send a separate invoice for each milestone on the same project, listing that stage's work.

Is the deposit credited automatically?

Only on a single completion invoice. When you bill by milestone, lower the first milestone by the deposit amount.

Can homeowners finance through Smarfle?

No. Loans and leases go through your finance partner, and Smarfle invoices what the homeowner pays you.

Where is the installed system kept?

On the customer, with the inverter, panels and battery, serial numbers, install date and warranty.

Can I add a panel upgrade after the site visit?

Yes. Revise the proposal, and once signed, the upgrade lines sit on the project for billing.

Do installers see the contract value?

No. Installers see the address, the system and the schedule, never the price.

Can I track what each install cost?

Yes. Hours and expenses on the project sit beside what you invoiced.
