Binding vs. Non-Binding Estimates, Explained

You sign a moving estimate expecting one number, and weeks later the invoice says something bigger. That gap almost always traces back to a single word buried in the paperwork: whether the estimate was binding or non-binding.

It sounds like fine print. It is actually the difference between a price you can plan around and a guess that can climb after your things are already on the truck. So here is the plain-English version of both, when each one shows up, and how to read your estimate before you sign it.

What a moving estimate actually is

An estimate is a mover’s written statement of what your move should cost, based on the items you are shipping, the distance, and the services involved. On a long-distance or interstate move, that number is usually built from the estimated weight of your household plus any extras like packing, stairs, or specialty items.

The key thing to understand is that not all estimates are promises. Some lock the price. Some only predict it. The label at the top of the document tells you which kind you are holding, and it changes how much protection you have if the final tally comes in high.

Binding estimates: the price is the price

A binding estimate is a guaranteed total for the specific items and services listed on it. If the estimate says the move costs a set amount, that is what you pay, even if the shipment ends up weighing more than the mover guessed or the day runs long.

There is one honest catch. A binding estimate only covers what is written on it. If you add boxes, ask for packing you did not originally request, or the crew finds a room that was not part of the walkthrough, the mover can revise the estimate before loading or bill you for the extras. As long as the job matches the paperwork, the number holds.

The upside is predictability. You know the figure going in, and you can budget the whole move as one line item. That is why binding quotes are common on planned, well-inventoried long-distance moves, which is how we handle our long-distance moving jobs.

Non-binding estimates: a good-faith guess

A non-binding estimate is the mover’s best prediction of the cost, not a locked price. The final bill is based on the actual weight of your shipment and the services actually performed, so it can land higher or lower than the quote.

Non-binding does not mean lawless. For interstate moves, federal rules cap what a mover can collect at delivery. This is the part worth memorizing.

The 110% rule

On a non-binding interstate estimate, the mover cannot require you to pay more than 110% of the estimated amount at the time of delivery to release your belongings. If the real cost comes in above that, the balance is billed later, and you generally have at least 30 days to pay it.

In plain terms: a non-binding estimate can grow, but it cannot hold your furniture hostage for a surprise number on the spot. Still, “up to 10% more, due on delivery day” is a real swing when you are already stretched thin from a move. A lowball non-binding quote that balloons is one of the oldest tricks in the business, which is a big reason we walk through how to choose a licensed mover before you sign anything.

The best of both: binding not-to-exceed

There is a third option that tends to favor you the most, and it is worth asking for by name. A binding not-to-exceed estimate (sometimes called guaranteed not-to-exceed) works like this: you pay the actual cost of the move, but never more than the quoted ceiling.

If your shipment weighs less than expected, you pay less. If it weighs more, you are protected by the cap. You get the downside of a low actual cost and none of the downside of a runaway bill. When a mover offers this, it usually means they are confident in their estimate and not counting on padding it later.

The three estimate types at a glance

Estimate type	What you pay	Main risk	Best when
Binding	The exact quoted price	Extras added later cost more	You have a firm, complete inventory
Non-binding	Actual cost, up to 110% due at delivery	The number can climb	You want a ballpark and understand it may move
Binding not-to-exceed	Actual cost, capped at the quote	Very little; the cap protects you	You want the most downside protection

Where this matters in Spokane (and where it does not)

Here is the local wrinkle. Most moves within the Spokane area are not priced by weight at all. Local moves are typically billed by the hour, so the binding versus non-binding question matters far less than it does on a cross-country haul. What drives a local bill is time: how much you are moving, how ready it is, stairs, and how far the truck parks from the door. We break that math down in how much movers cost in Spokane, and it is how we price our local moving work here in Spokane.

The estimate type becomes the headline question when you are leaving the area. A move to Seattle, across the state line into Idaho, or clear across the country is where weight, mileage, and the binding-or-not label decide your final number. That is exactly when you want the estimate type in writing, not verbal.

How to read your estimate before you sign

You do not need to be an expert. You need a few answers on paper:

• Is this estimate binding, non-binding, or not-to-exceed? The document should say so clearly at the top.
• What is included, item by item? A binding price only holds for what is listed, so make sure the inventory is complete.
• What happens if the weight or the job changes? Ask how a revision would be handled and when.
• Is there a not-to-exceed option? If they offer one, it is usually the safest choice for you.
• Is the estimate signed and dated by the mover? A real estimate is a document, not a text message.

If a company gets vague on any of these, that hesitation is your answer. An honest mover will happily explain which kind of estimate you are getting and why.

The bottom line

Binding locks the price. Non-binding predicts it and can rise up to 110% at delivery. Not-to-exceed caps it while still letting you pay less. For a local Spokane move, hourly pricing and a clear walkthrough matter more than the label. For anything long-distance, the estimate type is the number that keeps your final bill honest.
