Electrical work runs on licenses, permits, and inspections — and the invoice should carry all three without making the customer dig. This one arrives itemized like a real panel upgrade.
Yes — as a separate line at cost, like this template's example. The customer sees the city's fee distinctly from your work, and your books show the pass-through cleanly.
On materials-heavy jobs, commonly yes — enough to cover the panel, wire, and fixtures before they're ordered. Note the deposit terms on the estimate and the invoice both.
Materials usually are; labor depends on your state, and some states treat repair and new construction differently. Split them on the invoice — as here — and apply your state's rules, or ask your accountant.
For anything beyond a service call, send a quote first — this template switches to quote mode with a valid-until date. Accepted quotes become invoices without retyping the job.
