A customer gets a quote for a timing belt and water pump in March, declines it, and walks back in August holding the printout. "You said $950." Since then, the water pump went up, your labor rate changed, and the kit you quoted is on backorder. Clear estimate expiration rules stop that conversation from turning into an argument. They tell the customer, in writing, how long a price is good for, and give you a fair reason to re-quote when it is not.
Why Estimates Need an Expiration Date
An estimate is a snapshot of prices on the day you wrote it. Parts costs move, suppliers change their pricing, cores and fees change, and your own labor rate goes up over time. An estimate with no expiration date quietly promises those prices forever.
An expiration date also helps the customer. It gives them a reason to decide instead of letting a needed repair drift, and it makes clear that a new price later is not a trick. Most customers accept "this quote is good for 30 days" without a second thought. What they do not accept is finding out at pickup that the number changed.
How Long an Estimate Should Stay Valid
There is no single right answer. It depends on your parts mix, your market, and how stable your suppliers are. Some common approaches:
- Short window, such as 7 to 14 days, for jobs with volatile parts pricing, like engines, transmissions, or large electrical components.
- Standard window, such as 30 days, for most general repair. This is long enough for a customer to save up or get a second opinion.
- Longer window, such as 60 to 90 days, for simple maintenance where parts prices barely move.
Whatever you pick, print it on the estimate in plain language, near the total, where the customer will actually see it. "Prices valid for 30 days from the date above. Parts availability not guaranteed." Burying it in fine print on page two defeats the purpose.
Check your local consumer-protection rules as well. Some states and provinces have specific requirements about what a written estimate must include and how price changes must be handled once work is authorized. Your expiration policy should sit comfortably inside those rules.
Handling Parts Price Swings
The real risk is not the old quote that comes back months later. It is the price that changes between approval and the parts arriving, or halfway through the job.
Before approval
If you quote from a supplier catalog, confirm the price and availability before you send the estimate, especially for expensive parts. A few minutes spent confirming a $600 part is better than an awkward call later.
Between approval and ordering
Sometimes the customer approves on Friday and the supplier's price is higher on Monday. Decide as a shop how you handle small swings. Many shops absorb a small change on an approved job and call the customer only when the difference passes a set threshold. Write that threshold down so every advisor handles it the same way.
When a part is unavailable
If the quoted part is backordered and the alternative costs more, that is a new price and needs a new approval. Offer the options clearly: wait for the original part, or approve the alternative at the new price.
Here is how an illustrative re-quote might look:
| Line | Original estimate | Re-quote |
|---|---|---|
| Timing belt kit with water pump | $320 | $375 |
| Labor, 4.0 hr | $560 at $140/hr | $600 at $150/hr |
| Coolant and supplies | $70 | $75 |
| Total before tax | $950 | $1,050 |
Showing the old and new numbers side by side makes the change easy to understand. The customer can see exactly where the extra $100 came from. It also keeps the advisor honest: if a line went up, there should be a reason you can point to, such as a supplier price change or a posted labor rate increase. If you cannot explain a change in one sentence, check the line again before the customer sees it.
Re-Quoting an Old Estimate
When an expired estimate comes back, do not just print the old one with a new date. Treat it as a fresh estimate.
- Re-check the vehicle. If months have passed, the problem may have gotten worse. A seeping gasket may now be leaking hard. A worn tire may now be past the wear bars.
- Re-price every line. Pull current parts costs and apply your current labor rate and fees.
- Explain the difference. Tell the customer what changed and why, before they see the total.
- Get a new approval. The old approval, if there was one, does not cover the new price.
A good line for the counter: "That quote was from March, and it was good for 30 days. I've re-checked the car and updated the prices. The total is $1,050 now, mostly because the kit went up. Here's the breakdown." Calm, factual, and it points to the policy the customer already saw.
Keeping labor times consistent when re-quoting helps too. Pulling times from a labor guide means the only thing that changed is price, not your advisor's guess about the job.
Communicating Changes Before Work Continues
The most important rule is simple: if the price is going up on a job in progress, the customer hears about it before the extra work happens. Many jurisdictions require customer approval for charges above the authorized estimate, often above a set amount or percentage. Even where they do not, it is the only way to keep trust.
In practice, that means:
- Stop work on the affected item until you have approval.
- Send a revised estimate that shows what changed, not just a new total.
- Record the approval with the time, amount, and how it was given.
- Keep the original estimate on file alongside the revision.
A revised estimate the customer can approve from a link on their phone is faster than phone tag, and it creates a clean record. The Estimate Approvals by Text Message post covers how that works at the counter.
Setting Your Shop's Expiration Policy
You do not need a complicated policy. You need one that every advisor follows. Decide on a standard validity window, a threshold for absorbing small parts swings, and a script for re-quoting old estimates. Put the expiration wording on every estimate, and review the policy when your supplier pricing or labor rate changes.
AutoSoftWay dates every estimate, lets you send estimates by email or text in seconds, and gives customers a link for instant estimate approval, so revised prices get approved and recorded before the tech keeps going. You can request a demo to see how it fits your counter.
Pick your standard window today, add the wording to your estimate template, and brief your advisors on the re-quote script. The next time a six-month-old printout shows up, the conversation will take two minutes instead of twenty.
