What clients expect from a quote
Quotes often sound more fixed — clients may treat them as the price they will pay unless scope changes. Be explicit about what is included and what triggers a change order.
- Regional naming differs
- Both set client expectations
- Neither replaces an invoice
What clients expect from an estimate
Estimates imply a thoughtful projection that may adjust after discovery. Include validity dates and assumptions so clients understand pricing can change with scope.
- Validity / expiration date
- Scope summary
- Payment schedule if known
Moving to an invoice
After approval, convert the approved quote or estimate into an invoice with payment terms. Reuse line items to avoid mismatches between what was approved and what you bill.
- New document number for invoice
- Add due date and terms
- Match approved totals
