Estimate vs quote vs invoice vs receipt
An estimate, a quote, an invoice and a receipt are the four documents of one job, in that order. An estimate guesses the price, a quote fixes it, an invoice asks for payment, and a receipt proves it was paid.
Short answer
An estimate is a best guess that can change. A quote is a fixed price for a set scope, good until a date, and the customer approves it. An invoice asks for payment after the work. A receipt confirms a payment. Label each document clearly, and write any change down before doing it.

The four documents in one table
| Document | What it is | When you send it | What the customer does |
|---|---|---|---|
| Estimate | Your best figure for the job before every detail is known. | Before the work, often from a first look or photos | The customer decides whether to go further |
| Quote | A fixed price for a defined scope, good until a stated date. | Before the work, once the scope is clear | The customer approves it, often with a deposit |
| Invoice | A request for payment for work done, or a stage of it. | When the job or a stage is finished | The customer pays |
| Receipt | Proof that a payment was made. | Each time money is received | The customer keeps it; you keep a copy |
Estimate vs quote
In everyday use, an estimate is your best figure before every detail is known and may change with the scope; a quote is a fixed price for a defined scope, good until a date. The words are used loosely, so write on the document which one it is and how long the price stands.
How to write one, with the license-number rules and the FTC Cooling-Off Rule, is in how to write a contractor estimate.
Quote, approval and deposit
A quote becomes the agreement when the customer approves it. Keep the approval: a signature, a reply, or a tap with a date.
If you take a deposit on approval, several states cap it. The rules are in contractor deposit limits by state.
A sale signed at the customer’s home can also fall under the FTC Cooling-Off Rule, 16 CFR Part 429. The estimate guide explains when it applies.

Invoice
The invoice is the quote, settled: the same scope, any change orders, payments already made, and the balance due. The full checklist is in how to invoice as a contractor.
Receipt
A receipt shows the amount, the date and how the customer paid. The IRS lists receipt books and invoices among the documents that support your gross receipts, so keep both.

Change orders
A change order is a written change to the approved scope or price. Write what changes, the price difference and any new finish date, and get it approved before you do the extra work.

Common questions
What is the difference between an estimate and a quote?
In everyday use, an estimate is your best figure before every detail is known and may change with the scope; a quote is a fixed price for a defined scope, good until a date. The words are used loosely, so write on the document which one it is and how long the price stands.
Is a quote legally binding?
Once a customer accepts it, it can form a contract; whether it does depends on its terms and your state’s law. Write the scope, the price and how long it stands.
What comes first, an invoice or a receipt?
The invoice asks for payment; the receipt confirms it was paid.
Do I need both an estimate and a quote?
No. Many contractors send one document and label it clearly as one or the other.
What is a change order?
A written change to an approved quote’s scope or price, agreed before the extra work is done.
Can one app handle all four documents?
Yes. Several apps handle quotes and invoices together. LeadHunter USA CRM keeps all four on the customer’s record, free.
