How to write an estimate that gets accepted
Describe the project in one line at the top – “Bathroom renovation, 2nd floor” – then break the price into lines the client can understand: demolition, plumbing, tiling, fixtures, labor. A client who can see where the money goes argues less. Set a Valid until date; 30 days is typical, shorter if material prices move fast. The generator prints a highlighted note saying this is an estimate, not an invoice, so nobody pays it by mistake.
Use the Terms & assumptions box for what is and is not included: “Excludes permits”, “Price assumes access on weekdays 8–5”, “30% deposit to schedule”. The PDF ends with an Accepted by line and a date, so the client can sign and return it – the simplest possible contract. When the job is done, open the invoice generator, enter the same lines, and reference the estimate number.
Estimate vs quote: the difference matters in the UK
In the UK the words carry legal weight. A quote is a fixed price: once the customer accepts it, you cannot charge more for the work described. An estimate is an educated guess and the final bill may be higher or lower – but it should be reasonably close, and you should warn the customer before exceeding it. If you want a fixed price, retitle the document “Quotation” in your notes and word the terms accordingly. In the US the terms are used more loosely, but the same principle applies: say clearly whether the price is fixed or approximate, and what would change it. Several states require written estimates for specific trades (auto repair and home improvement contractors are the usual examples), sometimes with mandatory wording – check your state’s contractor rules.
Show tax the way the final invoice will show it. If you charge sales tax or VAT, include the rate so the client sees the true total; “plus tax” surprises are the fastest way to lose trust.
Common mistakes
- No expiry date. Without one, a client can come back six months later and expect last spring’s price.
- Lump sums. One line with a big number gets negotiated down; itemized lines get approved.
- Scope not written down. What is excluded is as important as what is included.
- Calling it an invoice. An estimate is not a request for payment. Keep the “not an invoice” notice on.
Frequently asked questions
Is an estimate legally binding?
An estimate is an approximation and is generally not binding on the exact figure, though it should be honest and reasonably accurate. A quote (fixed price) becomes binding once accepted. In the UK the distinction is well established; in the US it depends on wording and state law, so state clearly which one you mean.
How do I turn the estimate into an invoice?
Open the invoice generator, enter the same line items and add “Per estimate EST-0001, accepted on [date]” in the notes. Your sender details are already filled in on this device.
Can I ask for a deposit on an estimate?
Yes – state it in the terms (“30% deposit required to schedule the work”). The estimate itself is not a request for payment; once the client accepts, issue an invoice or receipt for the deposit.
How long should an estimate be valid?
30 days is the common default. Use 14 days if you depend on supplier prices that change often, or longer for large projects that need board approval.
Should the estimate include tax?
Show tax at the rate you will charge on the final invoice so the client sees the real total. If you are not registered for VAT or do not collect sales tax, leave the rate at 0.
