The short answer for Montana
Montana uses an online Secretary of State portal and separate MDT processes for commercial credentials.
If you haul federally regulated property for compensation in interstate commerce, the federal registration stack generally includes a USDOT number, operating authority, BOC-3 process-agent designation, accepted insurance filing, and UCR. State accounts are separate.
Interstate or intrastate?
Montana may impose intrastate registration, permit, tax, or insurance rules in addition to federal requirements. Confirm the exact rule with Montana Department of Transportation Motor Carrier Services before hauling only within Montana.
Interstate commerce
A shipment can remain interstate commerce even when your truck stays inside Montana. Look at the cargo's fixed and persistent intent, origin, and destination.
Pure intrastate commerce
State-only work can avoid federal MC authority while still requiring a state number, permit, insurance filing, tax account, or safety registration.

Costs to budget
Federal authority
$300
Per authority type; USDOT registration itself is free.
Insurance
Quoted
Driver, vehicle, cargo, radius, and location control the price.
State credentials
Variable
Montana registration, plates, permits, and taxes are separate.
Never treat an undated “all-in” number as a quote. Insurance and vehicle credentials usually create more variance than the federal filing fee.
