How to Create a Quotation Before Sending an Invoice

Jumping straight into work without a written quotation is a common freelancer mistake - it leaves pricing open to dispute later. A simple quotation, sent and approved before you start, protects both sides.

What Is a Quotation?

A quotation (or quote) is a document that states the estimated cost of goods or services before any work begins. Unlike an invoice, it's not a request for payment - it's a proposal the client can accept, negotiate, or decline.

Quotation vs Proforma Invoice vs Invoice

  • Quotation - sent first, informal pricing proposal, often before scope is fully finalized.
  • Proforma invoice - sent once scope is agreed, formatted like a real invoice but still not a payment demand.
  • Invoice - the final, binding request for payment after work is delivered.

What to Include in a Quotation

  • A clear breakdown of services or deliverables, with individual pricing where possible.
  • An estimated timeline for delivery.
  • A validity period, e.g. "This quote is valid for 30 days."
  • Payment terms you intend to use once the project is confirmed (advance %, milestones, etc.).

Turning a Quote Into Real Work

Once a client approves your quotation - even just by replying "sounds good" - keep that confirmation on record. It becomes useful if there's ever a disagreement about scope or price down the line.

From Quote to Final Invoice

When the work is done, convert the same numbers into a proper tax invoice with an invoice number, GST breakdown, and due date. FlowInvoice's generator makes it easy to reuse the same line items you originally quoted.
