EFS fuel cards backed by WEX with 12,000+ truck stop locations across North America — give OTR fleets excellent network coverage and purchase controls. What they don't give you is what happens after the transaction: automatic matching to GPS position, MPG variance detection, IFTA reconciliation, or cost-per-mile analytics tied to actual vehicle data. FleetRabbit's EFS integration closes that gap. Every transaction your drivers make automatically flows into your fleet dashboard matched to the right vehicle, cross-referenced against GPS, and flagged instantly if anything looks wrong.

How the EFS Integration Works — Setup to Live Data
The integration uses EFS's official Data Sharing Preferences in eManager — the same portal EFS provides for approved fleet management partners. No developer work, no API credentials to manage, no CSV exports. One authorisation in eManager, and transactions start flowing.
Log into your EFS eManager portal → Data Sharing Preferences → Add FleetRabbit as a Data Sharing Partner. EFS processes the connection within 1–5 business days. This is the only manual step in the entire setup.
FleetRabbit uses the EFS Unit Prompt — the vehicle number drivers key in at the pump — to automatically match each transaction to the correct vehicle in your fleet roster. Driver card assignments map automatically. No manual vehicle-to-card configuration required.
FleetRabbit imports 12 months of historical EFS transaction data on first connection — giving you an immediate baseline for MPG calculations, variance analysis, budget trending, and discount savings reports from day one.
From setup onwards, every EFS transaction syncs to FleetRabbit within minutes of processing. Each transaction includes date, time, truck stop location, driver ID, fuel type, gallons, price per gallon, total cost, discounts applied, and odometer reading — all imported automatically, no manual data entry ever.
The moment transactions start flowing, FleetRabbit runs 3 automatic cross-checks on every purchase — GPS proximity validation, tank capacity check, and baseline variance detection. Variance reports, IFTA reconciliation, and cost-per-mile analytics all go live immediately with no additional configuration.
3 Automatic Fraud Checks — Every EFS Transaction
Fuel fraud costs fleets an estimated 19–22% of their total fuel spend. EFS's own CarrierControl reporting is retrospective — you see the problem on your statement. FleetRabbit's cross-checks fire in real time, before the fraud compounds across weeks or months.
Every EFS transaction location is cross-referenced against the vehicle's GPS position at the time of purchase. If the truck stop doesn't match where the vehicle actually was — within a configurable radius — an alert fires immediately. Catches card sharing, personal vehicle fueling, and ghost transactions.
If the gallons purchased in a transaction exceed the vehicle's rated tank capacity, the transaction is flagged immediately — regardless of GPS position. This catches "slippage" (where fuel is diverted at the pump) and transactions where card controls haven't been properly configured per vehicle class.
FleetRabbit builds a rolling MPG baseline per driver and per vehicle that accounts for route type and load. If a driver's consumption significantly exceeds their personal baseline on a comparable route, the transaction is surfaced for review. Catches gradual behaviour shifts that no single transaction would flag on its own.
All three checks run automatically on every EFS transaction with no configuration required beyond the initial eManager authorisation. Start free and activate EFS fraud detection from day one →
EFS Variance Reports — What FleetRabbit Surfaces
Variance reports go beyond flagging individual suspicious transactions. They show patterns across your fleet — which vehicles, drivers, and routes are costing more fuel than they should, and by how much in dollars, not just percentage points.
Per-vehicle MPG compared against individual baselines and fleet average. Identifies trucks with developing mechanical fuel drain — injector wear, tyre pressure, air filter restriction — weeks before drivability symptoms appear.
Vehicle health signalRoute-normalised ranking showing which drivers cost more fuel per mile — and specifically what behaviour is driving the gap. Targeted coaching conversations backed by evidence, not guesswork.
Coaching dataActual EFS spend vs budgeted fuel cost — by vehicle, department, and fleet-wide. Monthly, quarterly, and annual trends. Forecasting that adjusts for seasonal patterns and route changes. Export-ready for budget presentations.
Financial reportingWhich truck stops your fleet uses most, per-gallon costs by location, and actual discount savings achieved from EFS network pricing. Identifies whether drivers are consistently missing in-network stops where EFS discounts apply.
Network optimisationEFS fuel efficiency data correlated with maintenance activity — did that engine tune-up actually improve MPG? Was that injector service worth doing? EFS + maintenance data answers these questions with numbers.
Maintenance ROIEFS transaction locations cross-referenced against GPS state-by-state mileage. Fuel purchased vs consumed per jurisdiction calculated continuously. Quarterly IFTA reports generated ready to file — not as raw data requiring manual assembly.
Compliance automationSee Your EFS Data in FleetRabbit — In 30 Minutes
Connect your EFS account and FleetRabbit shows you your fleet's actual MPG variance by vehicle, driver efficiency ranking, and which transactions flagged for review — all from your real EFS transaction history.
IFTA Automation — From EFS Data to Filed Report
IFTA quarterly reporting is one of the most time-consuming compliance tasks for interstate carriers. Manual assembly from EFS statements, GPS logs, and state mileage records typically takes 8–15 hours per quarter. FleetRabbit automates the entire process end-to-end.
Frequently Asked Questions
FleetRabbit supports all EFS-branded fuel cards including the EFS Fleet Card, EFS Fleet Mastercard, CrossRoads Freight Card, and Fleet One EDGE card. Note that EFS (a WEX subsidiary) uses a separate data integration path from standard WEX cards — you must connect via the EFS eManager Data Sharing Preferences rather than the WEX integration. WEX Fleet One is also supported through the EFS integration. Express codes and MoneyCodes are not included in the transaction sync.
Detection runs in real time as transactions sync from EFS — typically within minutes of the purchase posting. The three automatic cross-checks (GPS proximity, tank capacity, baseline variance) fire immediately on each transaction as it arrives. This is the critical difference from EFS's own CarrierControl reporting, which is retrospective — you see the problem on your statement days or weeks after it occurred. Note that some fuel vendors post transactions at end of day; in those cases, the delay is on the vendor's side, not FleetRabbit's.
FleetRabbit uses the EFS Unit Prompt — the vehicle number drivers key in at the pump — for automatic vehicle mapping. If a driver doesn't enter their unit number, the transaction creates as an "Unassigned" entry in your dashboard that you can manually map to the correct vehicle. You can bulk-assign unassigned transactions. To ensure clean automatic mapping, it's recommended to remind drivers to enter their unit number at every EFS pump. If the unit number doesn't exactly match the vehicle name in FleetRabbit, the system will also show it as unassigned for manual review.
MPG is calculated as: (Current Odometer − Previous Odometer) ÷ Gallons Purchased. FleetRabbit uses two odometer sources depending on your setup: GPS telematics odometer data (automatic, most accurate) or the odometer value drivers enter at the EFS pump (if GPS is not connected). Historical trending tracks 30-day, 90-day, and 12-month MPG averages per vehicle. Anomaly alerts trigger when MPG drops 10–15% below the vehicle's rolling baseline — surfacing mechanical issues or behavioural waste before they show up in a monthly report.
Yes — EFS fuel card integration is included in FleetRabbit's free tier for up to 3 vehicles, with no additional integration fee. Transaction sync, fraud detection, MPG analytics, and variance reports are all part of the core platform. IFTA automation is included on all paid plans starting at $3/vehicle/month. For a 25-vehicle fleet, the complete EFS integration platform costs $75/month — typically recovered through a single prevented fraud incident or one quarter of eliminated manual IFTA preparation time.
