The central distinction
A binding estimate fixes the price for the specified shipment and services, subject to applicable rules for changes. A non-binding estimate predicts the charges; it is not a guaranteed final price. Compare the inventory and service scope alongside the estimate type. A low opening number is difficult to assess without knowing what it includes.
Example one: the stated scope stays the same
Suppose a binding estimate is $4,000 for a documented inventory and packing scope. If that agreed scope remains unchanged, the binding amount applies under the estimate’s terms. With a non-binding estimate of $4,000, final charges can differ because they are calculated under the applicable tariff and services performed. These are illustrative numbers, not quotes or market averages.
Example two: you add work before pickup
Suppose you add a bedroom set and a storage stop after the estimate is issued. Ask how those additions affect the written estimate before loading. Do not assume that the word binding includes an unlimited inventory or every later service request. The revision should identify the changed scope and estimate type.
Understand the delivery-payment rule carefully
For an interstate non-binding estimate, the general delivery-payment limit is 110% of the estimated charges, with additional allowances for certain later-requested services and impracticable operations under the rules. On a $4,000 estimate, 110% is $4,400 before those allowances. This is not necessarily a cap on the final lawful bill; eligible remaining charges can be billed later.
Your estimate comparison checklist
For each offer, record the estimate type, inventory, packing, access assumptions, storage, valuation selection, delivery window, and payment schedule. Ask what can change the amount, when a revision would be provided, and how disputed changes are handled before loading. Keep every version of the paperwork.
Put the comparison into practice
