A quote and an estimate are similar in that they both provide an expected cost for a particular offering. The main difference between the two is that a quote is a fixed price that a customer agrees to pay, while an estimate is a rough calculation of the cost of an offering and may be subject to change.
A quote is typically more specific and accurate than an estimate template, as it is based on the actual cost of materials and labor, whereas an estimate is often a rough calculation based on the expected cost of these items.
Additionally, a quote is typically provided in writing and is legally binding, whereas an estimate is often provided verbally and is not necessarily binding.
