The Problem: Open-Ended Quotes Create Legal and Pricing Risk

A customer calls six months after receiving your quote and expects the same price. Material costs have moved, your schedule has changed, and you're left wondering whether you're legally obligated to honor a number you sent half a year ago. It's a common worry for service business owners, and the answer hinges on a distinction most people never think about.

Here it is: a quote is an offer, not a contract. As Catermonkey explains, "a quotation is an offer, not an agreement. An agreement only exists once the client accepts it." Until the customer accepts, your quote is simply a proposal — not a legally enforceable document. Payaca puts it plainly: a quote only transforms into a binding agreement once both parties sign and accept it.

The problem arises when a quote has no stated expiry date. Without one, a vague "reasonable period" applies — and that's where things get murky. In Australia, Sprintlaw notes that an implied "reasonable time" can be hard to define in a dispute. What's reasonable to you might not be reasonable to a customer expecting the old price months later.

Most jurisdictions don't mandate a validity period at all — you set it. Industry research shows common windows run 7 to 30 days, with 14 to 30 days standard for most service businesses. That's no accident: one analysis recommends 30 days precisely because material costs can swing 10–20% in a single quarter.

A few things worth knowing about how this plays out:

• After expiry, you're free to re-quote. As Catermonkey notes, prices may have changed in the meantime, and you're not bound by the old quote if the client wants to accept after the expiry date.
• Once a quote *is* accepted, it becomes binding — and changes then require mutual agreement. You cannot unilaterally raise pricing, reduce scope, or extend timelines.
• Jurisdictions vary. France is a notable exception: an unsigned quote with no stated expiry is legally valid for three months there, so check local rules if you operate internationally.

The practical takeaway: put a clear expiry date on every quote, and state what happens when it lapses. That single step prevents a client from returning months later expecting an amount you can no longer honor.

It also turns expired quotes into opportunities rather than headaches. Since you're legally free to re-quote after expiry, an old quote is a legitimate, permission-based reason to reconnect — which is exactly how reactivation campaigns like the old quote follow-up work at CallMyCustomers, with the business owner approving the fresh offer before anything goes out.

(Note: this is general guidance, not legal advice — quote validity rules vary by jurisdiction, so consult a qualified lawyer for your specific situation.)

The Legal Answer: You Set the Validity Period — With One Notable Exception

The short answer surprises most business owners: in the United States and most other jurisdictions, no law tells you how long a quote must stay valid. You set the validity period — not a statute. As one industry guide puts it plainly, "There's no legal requirement for quote validity. You set the expiration date." Australian legal guidance reaches the same conclusion, noting that no national law prescribes a validity period, with businesses commonly choosing 14, 30, or 60 days depending on supply volatility and scheduling lead times.

What matters legally is what a quote is. A quotation is an offer, not an agreement — an agreement only exists once the client accepts it. Before acceptance, it remains a proposal rather than an enforceable contract, as contract specialists explain. Notably, US federal procurement rules codify this: under FAR 13.004, "a quotation is not an offer and, consequently, cannot be accepted by the Government to form a binding contract."

Typical validity windows vary by industry, according to pricing benchmarks and sector norms:

• Home repair and construction: 10–21 days, reflecting volatile material costs
• Professional services: around 7 days, given faster sales cycles
• Consulting: roughly 30 days for longer decision timelines
• General service businesses: 14–30 days as the common standard

One notable exception exists: France. There, an unsigned quote with no stated expiry is legally valid for three months by statutory default, and validity disclosure becomes mandatory above €100/month. A signed French quote carries the same weight as a binding contract.

Also worth distinguishing: a quote versus an estimate. A quote is a firm, itemized price valid for a set period; an estimate is a non-binding approximation allowing movement. As construction software experts note, the quote — not the estimate — is the document that becomes part of your contract.

The practical upshot for US service businesses: an expired quote legally frees you to re-quote with updated pricing, which is why old quotes are a legitimate, permission-based reason to reconnect with past customers — a reactivation angle CallMyCustomers builds campaigns around, with the owner approving every fresh offer before it goes out.

The Solution: A Compliant Quote Validity Policy That Protects Your Margins

Because a quote is an offer rather than a contract, the smartest move isn't hoping for the best — it's building a validity policy that protects your pricing from day one. The good news: since you set the validity period yourself in most jurisdictions, you have full control over how that policy works.

Start with the single most important compliance step: put an explicit expiry date on every quote. Without one, a vague "reasonable period" applies that is difficult to define in a dispute, as Australian legal guidance notes. Use a specific calendar date — "Valid until July 15, 2026" — rather than a day count that forces the client to do the math, and make it prominent on the document, not buried in fine print.

Next, match your validity length to your cost volatility and typical sales cycle. For service businesses where material costs can swing 10–20% in a single quarter, a 30-day expiration is the recommended standard. Stable, simple work can carry a longer window; volatile or complex jobs warrant shorter ones.

Your policy should also spell out what happens after expiry. A practical guide to quote validity recommends documenting a consistent policy for honoring versus re-quoting lapsed quotes, so clients know upfront that prices or dates may need review once the quote lapses. If a client asks for more time, log the extension with the new expiration date and the reason for the adjustment — that transparency keeps you from being held to outdated terms.

A few more habits round out a compliant policy:

• Get written acceptance — even a simple email reply provides proof if a dispute arises later.
• Treat post-acceptance terms as locked: once a quote becomes binding, changes require mutual written agreement from all parties.
• Consider collecting a 20–40% deposit at acceptance to cement the commitment on both sides.
• Retain your quotes and invoices for 7 years to stay compliant with tax record-keeping requirements.

One more thing worth remembering: an expired quote isn't a dead end. Once it lapses, you're free to issue a fresh quote with updated pricing — which makes old, never-booked quotes a legitimate, permission-based reason to reconnect with past customers. That's exactly the kind of follow-up CallMyCustomers runs for service businesses, with the owner approving every message and offer before anything goes out.

Set the policy once, apply it to every quote, and your margins stay protected no matter when a customer finally says yes.

The Opportunity: Turn Expired Quotes Into Booked Work

An expired quote isn't a dead end — it's a legally clean starting point. Once a quote lapses, the business is free to issue a fresh one with updated pricing and terms, since it's no longer bound by the old quote if the client tries to accept after the expiry date. That legal freedom is exactly what makes dormant quotes one of the most overlooked revenue sources a service business owns.

The mechanics work in your favor. A quote is an offer, not a contract — it only becomes binding upon acceptance — so expired quotes are not automatically enforceable and clients may simply need a new quote with current pricing. Meanwhile, industry norms keep validity windows short: 14–30 days is standard for most service businesses, and even 30 days is recommended because material costs can swing 10–20% in a single quarter. In other words, most of the quotes sitting in your files expired long ago — and every one of them is a legitimate reason to reconnect.

The challenge is doing it in a way that feels useful rather than pushy. That's where a structured Old Quote & Estimate Follow-Up campaign earns its keep, giving the outreach a genuine reason to exist:

• A fresh angle on the old quote — updated pricing, availability, or a seasonal hook tied to when the customer actually needs the work
• Calls, texts, and emails sent in the business's own name, so the customer hears from a brand they already know
• Replies routed straight back into the existing booking process, with confirmations and no-show follow-up
• Typical win-back campaigns running two to four weeks end-to-end, often with replies from the first wave

Control matters as much as the campaign itself. With a done-for-you service like CallMyCustomers, the owner approves every script, offer, and message before anything goes out — the campaign is planned together, signed off, then run. And before any fee changes hands, a free list review shows exactly what those dormant quotes can produce, segmented by recency: 30 days, six months, twelve-plus months.

The economics make the case on their own. Reactivating a customer costs roughly 5x less than acquiring a new one, and most customers simply forget a business within about twelve months — they didn't reject you, they just moved on. One well-timed, approved follow-up is often all it takes to turn a lapsed quote into booked work, with pricing and terms you're free to set fresh.
