OptiMile Pro vs ProMiles: An Honest Fuel Optimizer Comparison

ProMiles and OptiMile Pro are both true fuel optimizers — both compute how many gallons to buy at each stop, and both optimize on post-IFTA cost. This isn't a hit piece on the veteran. It's an honest comparison of two tools that do the same math and deliver it very differently.

Start With the Credit: Both Do Real Optimization

ProMiles' paid Fuel Opt goes well beyond finding cheap stations. It will have a driver buy a minimum at one stop to reach a cheaper one later, using tank capacity, MPG, start and end fuel, out-of-route distance, and minimum purchase — and it compares prices net of refundable fuel tax. That's genuine IFTA-aware, fill-amount optimization, from a company that's been doing routing and fuel-tax math for about four decades.

OptiMile Pro does the same class of optimization. On core math, treat these as peers. The differences are in what surrounds the math: data, delivery, setup, and platform.

At a Glance

Prices and Data

ProMiles bundles its own large daily truck-stop price database and lets you import your fuel network's price sheet. OptiMile consumes your contracted prices exactly as you upload them — customer-authoritative, never altered. If you want a built-in national retail price feed, that's a ProMiles strength; if you want optimization strictly on your negotiated contracts, that's OptiMile's model.

Per-Driver MPG: Assumption vs Measurement

ProMiles optimizes against an MPG figure you set per unit. OptiMile reads each driver's actual measured MPG from your telematics — Samsara, Motive, or Geotab — so the plan reflects how that driver really burns fuel, not a static assumption. On a long route, the difference between an assumed 6.5 and a measured 7.1 MPG changes where the optimal stops fall.

Daily Workflow and Delivery

With ProMiles, a dispatcher generates the plan and the driver follows it — the software is a tool the dispatcher drives. With OptiMile, the optimized plan is texted to the driver automatically, and for TMS-ingested loads it can generate the moment the load lands. Less manual work per trip, and no driver app to adopt.

Platform, Setup, and Pricing

ProMiles' engine is trusted, but its interface is dated, with a learning curve — and the desktop XF product carries periodic paid version upgrades to keep road and toll data current. OptiMile is a modern cloud app with nothing to install and no upgrade fees.

Setup is the sharpest contrast for lean back offices: ProMiles is largely self-configured, while OptiMile's team connects your TMS and telematics for you — your IT staff never scopes an integration.

On price, be fair to the veteran: ProMiles wins on headline entry cost (web from ~$49/month, with much of its pricing quote-based). OptiMile is transparent per-truck pricing — $50–$75 per truck per month with volume discounts — plus a 30-day free trial with no card. If the lowest sticker price is the priority, ProMiles has the edge; if you want predictable per-truck pricing with downside protection, that's OptiMile.

Who Each Is Best For

ProMiles fits owner-operators and small/mid fleets that want a proven optimizer at the lowest entry cost, already do their own routing and IFTA in-house, and don't mind older software and manual setup. Its longevity and price are real advantages.

OptiMile Pro fits OTR fleets that want the optimization and want the manual work removed: done-for-you integration, plans texted to drivers, per-driver measured MPG, modern UX, and a guarantee — at any fleet size.

Switching From ProMiles

No rip-and-replace: keep your fuel contracts and routes. We import your contracted pricing, connect your TMS and telematics for you, and start texting optimized plans to drivers — typically same-day via manual upload while integrations finish. And your first month is a free trial: if the savings don't show up, you never pay us.
