Estimate
An estimate is an approximate price a seller gives for work before it starts, which can change as the job progresses.
An estimate is your best-guess price for a job when the full scope isn't nailed down yet. It gives the client a realistic ballpark so they can plan a budget, while leaving room for the final cost to move up or down. Estimates are common in trades, repairs, and any work where the exact effort is hard to predict in advance.
What it means
An estimate is an informed approximation, not a commitment. You base it on what you know at the time, knowing that the real cost may differ once the work is underway and the details become clear.
Because it isn't fixed, a good estimate explains its assumptions: what's included, what could change the price, and roughly how much. That transparency helps clients avoid sticker shock and keeps the relationship honest when the final number lands.
Estimate vs. quote
The key difference is how firm the number is.
- An estimate is approximate and may change
- A quote is a fixed, committed price for a defined scope
- Use an estimate when the scope or hours are still uncertain
- Convert an estimate into a quote or invoice once the work is defined
Example
A plumber inspects a leak and estimates $300 to $450, noting the final price depends on whether a pipe needs replacing. The client approves the range, and once the job is done the actual cost falls within it.
In practice, many small businesses send a quote rather than an estimate when they can pin down the scope, because a fixed price is easier for clients to approve. Platybooks's quote workflow covers that committed-price case directly.
Frequently asked questions
Is an estimate the same as a quote?
No. An estimate is an approximate figure that can change as the work progresses, while a quote is a fixed price for a defined scope. If you can define the work precisely, a quote gives the client more certainty.
