Choose between a quotation and an estimate based on scope certainty, pricing risk and client expectations.
A quotation is more definite
A quote commonly presents a defined scope and price that is intended to remain valid for a stated period, subject to its terms. It should list assumptions, exclusions, taxes, delivery and acceptance requirements. Avoid calling a rough range a fixed quotation.
An estimate allows uncertainty
An estimate is an informed projection when quantity, time or scope is not fully known. Explain what may change and how final charges will be measured. The word "estimate" alone is not enough; make the assumptions visible.
Match the sales stage
Use an estimate during early discovery and a quotation after requirements become clear. For complex projects, provide an estimated discovery phase followed by a firm quote for implementation.
Frequently asked questions
Is a quotation automatically a contract?
Not always. Legal effect depends on the wording, acceptance, surrounding agreement and applicable law.
Can an estimate include VAT?
It can show expected VAT, but the final tax treatment follows the actual supply and applicable rules.
