Estimate, quote, bid, or proposal: what should you send?

An estimate usually gives an expected cost, a quote usually states a price for a defined scope, a bid responds to a competitive request, and a proposal explains an approach as well as the price. Businesses use these words differently, so the document should spell out what you’re offering.

Use an estimate when some details remain open

Explain what the number is based on and what still needs to be confirmed. For example, a repair may depend on what you find after opening a wall. Identify allowances or unpriced items instead of letting the total suggest more certainty than you have.

In PayPolka, a Price TBD line can identify an item you haven’t priced yet. It doesn’t add to the estimate total, and you need to price its invoice placeholder before sending a full invoice.

Use a quote for a defined price and scope

Make the included work and exclusions clear, along with the time available to accept and the process for changes. A fixed amount is easier to discuss when both sides can see what it covers.

The label alone doesn’t establish the legal effect of the offer. If you need certainty about contract wording or obligations, have your terms reviewed for your work and location.

Follow the request when submitting a bid

A customer or general contractor may specify a format, required details, and a deadline. Use their requirements rather than assuming your usual estimate is enough.

Check that your response covers the requested scope and identifies any exceptions. Keep a copy of the exact submission and its supporting documents.

Use a proposal when the approach needs explaining

For consulting or creative work, the client may need to understand the plan, deliverables, and responsibilities before the price makes sense. A proposal gives you room to explain those choices.

You can attach proposal files to a PayPolka estimate so the client can review the context alongside the priced work. Keep the estimate and attachments consistent before sending them for acceptance.

Make the next step clear

Whichever name you use, say how the client can accept, ask a question, or request a change. Once an estimate is accepted in PayPolka, you can create invoices against the agreed amount.
