Electrical quote, bid or proposal: the same form
Customers ask for an electrical quote, a bid or a proposal as often as for an estimate. For a repair or a small install it is the same paper: who it is for, the lines, the total and how long the price holds. In the Word and Excel files you can change the title from Estimate to Quote, Bid or Proposal, whichever word your customer used.
A bid or a proposal for a bigger job, such as a panel replacement or new circuits for a remodel, usually carries more: the panel or the fixtures by size and type in plain words, how many circuits, outlets or fixtures, what is being removed, and what the price leaves out, for example patching and painting. Put those on their own lines or in the notes.
Some people say quote for a fixed price and estimate for a best guess. Whichever word is on top, write on the paper whether the price is fixed or may change once you can see the wiring.
