Princeton TMX+MileMaker
Truck-specific distance from MileMaker, a Rand McNally company, calculated inside the platform you already use to plan, tender, track, and audit freight.
INTEGRATION BENEFITS
MileMaker Mileage and Routing, Inside Princeton TMX
Distances and transit times reflect how trucks actually move, not rough point-to-point guesses.
Rate and audit with confidence
Precise mileage gives you a solid basis for rating, freight audit, and cost analysis.
Plan from a single source of truth
One consistent routing logic feeds network design, lane planning, and day-to-day execution.
Close the planned-to-invoiced gap
Fewer surprises between the miles you planned, the miles you rated, and the miles you're billed for.
Integration Details
The Princeton TMX + MileMaker integration puts commercial-grade truck routing and industry-standard mileage directly into your transportation planning and analytics. Because MileMaker's data accounts for real-world truck routing, not just point-to-point estimates, teams can rate lanes with confidence, plan more accurately, and execute more consistently across every lane and mode.
Who This Integration Is For
- Transportation & Logistics Teams
- Network Planning & Optimization Teams
- Freight Audit & Cost Management
- Finance & Budgeting Teams
- Supply Chain Analytics
- IT & Integration Owners

Frequently Asked Questions
How do I enable MileMaker in Princeton TMX?
Existing customers should contact their account team. The engine and routing version are configured at the company level, so there is no change to how your team enters or plans loads. If you are not yet a Princeton TMX customer, start with a demo.
How does mileage variance show up in freight audit?
As a small per-load gap between the carrier's invoiced distance and the distance on your load record. Individually too small to question, materially large across thousands of loads. Calculating distance in the same system that audits the invoice removes the reconciliation step.
How does the mileage engine affect fuel surcharge?
Fuel surcharge is usually calculated per mile against a published index, so distance multiplies straight into the charge. A mileage discrepancy moves the surcharge as well as the linehaul, which is why mileage problems often surface first as a fuel surcharge dispute.
Can I still override the distance on specific lanes?
Yes. Lane distances you have negotiated and configured in Princeton TMX take precedence over the calculated value. Changing engines does not overwrite contracted mileage. That matters whenever a customer or carrier agreement fixes a distance no routing engine would independently produce.
Can I use my existing MileMaker license with Princeton TMX?
Yes. If you already hold a MileMaker agreement, you can supply your own API key and keep billing directly with MileMaker. If you don't, Princeton TMX can provision access as part of your contract. Your account team can set up either path.
Does Princeton TMX still support PC*MILER?
Yes. PC*MILER from Trimble MAPS remains fully supported and is what many Princeton TMX customers use today. MileMaker is an added choice, not a replacement. The engine is set per company, so you pick the one your carrier agreements are written against.
How do shippers and carriers agree on mileage for rating?
Both sides name the same three things in the contract: the mileage engine, the routing type, and the version. With those fixed, the same lane returns the same distance for everyone. Most mileage disputes trace back to a term nobody specified, not to a calculation error.
What is the difference between practical, shortest, and truck-legal miles?
Practical miles follow the route a driver would realistically run, favoring highways and legal truck routes. Shortest miles minimize distance and can route a truck onto roads it cannot legally use. Truck-legal routing enforces clearance, weight, and hazmat limits. Most freight contracts are written on practical miles.
Why do my miles and my carrier's miles disagree on the same lane?
Almost always one of three causes: different engines, different versions of the same engine, or different routing types. Version is the sneakiest, road data changes continuously, so two versions of the same product can return different distances for identical origin and destination points.
