How to Make a Quotation: Scope, Terms, and Sending

To make a quotation, write a dated, numbered document that names both parties, itemizes the goods or services with prices, defines the scope, sets an expiration date and payment terms, adds a short set of protective clauses, and delivers it as a PDF the buyer can sign. Done well, it locks in your price for a set window and gives you a clean paper trail if the buyer later disputes what was included.

The rest is detail, and the detail is where quotes either hold up or fall apart.

Quote, Estimate, or Proposal

Pick the right document before you start drafting. A quote states a fixed price for a defined deliverable. An estimate is a rough projection, not a commitment. A proposal is a longer pitch, common in competitive bidding, that presents your approach alongside pricing and timelines. If you label something a “quote” when you meant a loose estimate, the buyer can reasonably expect you to honor that price. Use an estimate when costs are unpredictable and say so on the document. Use a quote when you can commit to a number for a specific scope.

What to Include in a Quotation

Every quote should carry the same core pieces of information. Missing any of them invites confusion or a dispute you can’t win.

  • A unique quote number. Both sides need a reference to track the document through accounting and email.
  • Issue date and expiration date. The validity window protects you from honoring stale pricing if material or labor costs shift. Most quotes stay open for 14 to 30 days; volatile industries like construction or hardware supply sometimes use windows as short as 7 to 10 days.
  • Business details for both parties. Your legal business name, address, phone, email, and website, and the buyer’s legal name and address if the buyer is a business. These establish who is bound if the quote becomes an agreement.
  • Your tax identification number. Businesses with employees, or that operate as a partnership, LLC, corporation, or tax-exempt organization, need an Employer Identification Number from the IRS. Including your EIN or TIN on the quote supports financial reporting on both sides.1Internal Revenue Service. Employer Identification Number2Internal Revenue Service. Taxpayer Identification Numbers (TIN)
  • Itemized pricing. Break out every product, service, or labor category with quantities and per-unit costs. A single lump sum invites questions. An itemized list makes it harder for either side to dispute what was included.
  • Payment terms. When payment is due, what methods you accept, and whether you require a deposit before work begins. Half upfront is standard in many industries because it covers your material costs.
  • Delivery or completion timeline. When goods will ship or work will finish. A quote without a timeline leaves the buyer guessing and gives you no defense if they expected faster delivery.
  • Your license number, if your industry requires a professional or contractor license. Many states mandate this on formal business documents.

    Writing the Scope So It Holds Up

    The scope section is where most quotation problems begin. A vague scope lets the buyer assume extra work is included. A tight scope draws a line around exactly what the quoted price covers.

    Describe every task, deliverable, or product in specific terms. Instead of “website redesign,” write “redesign of five existing pages with responsive layout, not including new copywriting, photography, or e-commerce functionality.” That version tells the buyer what they’re getting and what they’re not. Listing exclusions is as valuable as listing inclusions, because most pricing disputes grow out of assumptions that were never written down.

    Build in a change order process. State that any work outside the original scope requires a separate written agreement with its own pricing before that work begins. Without this clause, the client who asks for “just one more thing” repeatedly will balk when the final invoice reflects the extra labor.

    Handling Sales Tax

    Leaving sales tax off a quote is one of the most common small-business mistakes, and it creates an awkward conversation when the final bill is higher than the quoted number. If your state imposes sales tax and what you sell is taxable, either fold the tax into the line items or show it as a separate line at the bottom.

    Which rate applies depends on where you operate and where the buyer is located. About a dozen states tax sales based on the seller’s location; the majority tax based on the buyer’s. For remote sales across state lines, destination-based sourcing almost always applies. Businesses selling into multiple states should also watch economic nexus thresholds: most states require you to collect once you exceed $100,000 in sales into that state, even without a physical presence there. If a buyer gives you a valid exemption certificate, omit the tax and keep the certificate on file.

    Reimbursable Expenses

    Some costs sit outside the fixed price but remain the buyer’s responsibility, such as travel, shipping, permit fees, specialty materials, and third-party services. Add a short section to the quote that names these categories, states that they’ll be billed at cost with documentation, and sets any caps or approval thresholds. For example, travel expenses over $500 might require the buyer’s advance written approval. Requiring receipts before reimbursement prevents vague cost padding.

    Protective Terms and Conditions

    A quotation is a business document, not just a price list. A short terms section manages your risk without turning the quote into a wall of legalese.

    • Limitation of liability. Caps your financial exposure if the project doesn’t go as planned. A common approach limits your total liability to the amount the buyer paid under the quote. Courts generally enforce these clauses when the language is clear and conspicuous, though they’re harder to enforce if they try to eliminate liability for negligence entirely.
    • Force majeure. Shields you from penalties when events outside your control prevent delivery. Natural disasters, supply chain disruptions, and government-imposed restrictions are typical triggers. Specify which events qualify and require prompt written notice from the affected party.
    • Governing law. Names the state whose laws apply to any dispute when the parties are in different states. Courts generally honor the choice.4Legal Information Institute. Governing Law
    • Cancellation terms. Spell out what happens if either side cancels after acceptance. Can the buyer cancel for any reason? Do they forfeit the deposit? Do you owe a partial refund if you haven’t started work? Silence invites messy disputes.

    When a Quotation Becomes Binding

    A quotation is not automatically a legal offer. Contract law generally treats a price quotation as an invitation to negotiate rather than a binding commitment. Whether a quote crosses the line into a binding offer depends on how complete the terms are, whether it responds to a specific inquiry, and whether the language shows the seller intends to be bound.

    An important exception applies to merchants selling goods. Under the Uniform Commercial Code’s firm offer rule, a merchant who puts an offer in a signed writing that promises to stay open makes that offer irrevocable for the stated period, up to a maximum of three months, even without the buyer paying to hold it open.5Legal Information Institute. UCC 2-205 Firm Offers Language like “this price is guaranteed for 30 days” creates a firm offer you can’t revoke during that window.

    Once a buyer accepts a quote that qualifies as an offer, a contract forms. Acceptance can happen through a signed copy, a purchase order, or in some situations by beginning the requested performance.6Legal Information Institute. UCC 2-206 Offer and Acceptance in Formation of Contract For sales of goods above $500, the UCC also requires some form of written confirmation signed by the party you want to hold to the deal. Always get the buyer’s signature or written acceptance before starting work, and keep a copy.

    Formatting and Sending the Quote

    The content matters more than the design, but a clean layout is the difference between a quote read carefully and one skimmed. Put your business name, logo, and contact information at the top. Group the itemized costs in a table with clear columns for description, quantity, unit price, and line total. Place the grand total near the bottom where it’s easy to find. Separate the terms and conditions from the pricing. Use bold headers sparingly to guide the reader’s eye toward the total and the expiration date.

    Convert the document to PDF before sending. A PDF preserves your formatting across devices and prevents accidental or intentional edits to the price or terms. Send it by email or upload it to the buyer’s procurement portal. Either method creates a timestamped record of when the offer was delivered.

    Getting the Quote Signed

    You don’t need a wet-ink signature. Federal law provides that a signature or contract cannot be denied legal effect simply because it’s in electronic form.7Office of the Law Revision Counsel. 15 USC 7001 General Rule of Validity

    For an electronic signature to hold up, it needs to be attributable to the signer, attached to or logically associated with the document, and executed with intent to sign. Platforms like DocuSign, Adobe Sign, and HelloSign handle these requirements automatically by logging the signer’s identity, email, IP address, and timestamp. If you send quotes to consumers rather than businesses, the law also requires you to inform them of their right to receive a paper copy and to get their consent to the electronic process before proceeding.8National Credit Union Administration. Electronic Signatures in Global and National Commerce Act Adding a signature line to the PDF and routing it through an e-signature platform gives you a defensible record and cuts turnaround time dramatically compared with printing, signing, scanning, and emailing back.

    After the Buyer Accepts

    Once you hold a signed quote or a matching purchase order, the quotation becomes the pricing foundation for the project. Service providers typically convert the accepted quote into a service agreement that incorporates the quoted terms and adds milestones and reporting schedules. Product sellers generate an invoice that mirrors the quote’s line items and payment terms.

    If the buyer requests changes after acceptance, run them through the change order process built into your scope section. Issue a revised quote or addendum with the new pricing, get it signed, and then proceed. Skipping this step is the fastest way to end up doing unpaid work. File the signed quote alongside the corresponding invoice and any change orders; those records support your tax filings and give you a clear paper trail if a payment dispute ever reaches collections or court.3Internal Revenue Service.
