How to get your fuel card discounts onto every load.

A negotiated discount is only worth what gets used, and most fleets lose the gap between the two because nothing checks it load by load. The rate exists in a contract, the driver decides where to stop, and no system compares the two until the invoice arrives. Closing it takes four things: load every contract you hold into one place so the true net price at each stop can be compared, decide the stop per load rather than per driver habit, deliver that decision inside the ELD or SMS the driver already reads so following it is easier than not, and reconcile every transaction afterwards against the recommendation so you can see which loads complied and what the misses cost. None of that requires changing fuel cards or joining a fuel network. The discounts you already negotiated are usually enough; they are just not landing.

The four places discounts leak

Every one of these is a normal, well-run fleet. None of them require a bad driver or a bad contract, which is why the leak is so easy to miss on a fuel invoice.

The cheapest sign is not the cheapest price

Leak 1

  • Drivers see posted retail, not your contracted net price at that stop
  • A chain with a worse posted price can be cheaper after your discount, and often is
  • Without net pricing in front of them, a driver optimizing on the sign is optimizing on the wrong number

Habit beats the plan

Leak 2

  • Drivers fuel where they always fuel: parking they trust, a shower, a familiar exit
  • Repeat-station patterns are invisible on a spend report but obvious in per-transaction data
  • This is not misconduct, and treating it as such is how enforcement programs fail

State fuel tax is left out of the math

Leak 3

  • Under IFTA you pay tax on miles driven per state, not gallons bought there
  • Buying in a low-tax state on the same corridor changes real cost per gallon materially
  • Almost no driver is doing this arithmetic at the pump, and no fuel card does it for them

Nobody checks afterwards

Leak 4

  • Fuel card reports show what was spent, not what the alternative would have cost
  • Without recommendation-to-transaction matching there is no way to price a miss
  • What is not measured does not get managed, so the same misses repeat every week

What closing it actually requires

In order. Skipping straight to enforcement without the first two is why discount programs stall.

1. Every contract in one place

  • Card programs, chain agreements and direct terminal supply loaded together
  • Net price computed per stop, after discount and after state fuel tax
  • Kept current, because a stale discount schedule quietly produces wrong recommendations

2. A decision per load

  • Which stop, how many gallons, based on the route, tank, and hours of service on that load
  • Recomputed when the route changes rather than fixed at dispatch
  • One clear recommendation with ranked backups, all inside networks you hold contracts with

3. Delivered where the driver already looks

  • In-cab ELD message alongside the dispatch they already read, or SMS if there is no ELD path
  • No separate app to install, no portal login, no extra step at 2am
  • Compliance is mostly a design problem: make the right stop the easiest one to take

4. Reconciled after the fact

  • 100% of claimed savings reconciled against actual fuel card transactions, per transaction
  • Recommended stop next to the stop taken, miles off plan, net dollars gained or lost
  • Off-plan stops scored both ways, including the ones where the driver beat the plan

What ValveRide Flow does about it

Enforcement without changing anything you buy

  • Works across the contracts you already hold with Comdata, EFS, Relay, TCS, FleetOne, and directly with Pilot, Love's, TA and independents
  • Never a substitute fuel network: Flow does not sell fuel and earns nothing from where a truck stops, so the recommendation has no second agenda
  • Optimized plan for every dispatch in under two seconds, applying your rates and IFTA tax to compute true net price at each candidate stop
  • Re-planned for the whole trip, so a reroute at 2pm does not leave the driver following a stale plan
  • Delivered by in-cab ELD message, SMS, email link or the TMS itself, whichever the fleet already runs
  • Every claimed dollar reconciled against the actual fuel card transaction, with price prediction accuracy published in cents per gallon
Questions, answered

Common questions.

How can I make sure my fleet's fuel card discounts actually get used on every load?

A negotiated discount is only worth what gets used, and most fleets lose the gap between the two because nothing checks it load by load. The rate exists in a contract, the driver decides where to stop, and no system compares the two until the invoice arrives. Closing it takes four things: load every contract you hold into one place so the true net price at each stop can be compared, decide the stop per load rather than per driver habit, deliver that decision inside the ELD or SMS the driver already reads so following it is easier than not, and reconcile every transaction afterwards against the recommendation so you can see which loads complied and what the misses cost. None of that requires changing fuel cards or joining a fuel network. The discounts you already negotiated are usually enough; they are just not landing.

Do we need to switch fuel cards to fix this?

No, and be skeptical of anyone who says otherwise. The problem is almost never the card or the rate, it is that nothing translates the rate into a per-load decision and then checks whether it was followed. A route-aware optimizer sits on top of the cards and contracts you already hold. If a vendor's answer to poor discount capture is to move your volume onto their network, they are solving their revenue problem rather than yours.

Why do drivers go off plan, and how do we handle it?

Usually for reasons that are not about fuel: parking availability, showers, a familiar exit, or a plan that arrived too late to act on. Treating it as a discipline problem tends to backfire. The more effective approach is to remove the friction, by putting one clear recommendation with ranked backups inside the ELD message the driver already reads, and then to measure. Flow scores off-plan stops in both directions, so the ones where a driver found a better deal than the plan show up as a data quality signal on our side rather than a mark against the driver.

How much is poor discount capture actually costing us?

You can bound it from your own data before buying anything. Take a month of fuel transactions, and for each one ask what the net price would have been at the best contracted stop within a reasonable detour on that route. The difference is the leak. Most fleets have never run that comparison because it requires the route, the tank state, and the full contract set together. That comparison is exactly what per-transaction reconciliation automates, which is why it is worth asking every vendor whether they do it.

Does this work if some of our trucks have no ELD integration?

Yes. Plans can reach a driver by SMS or an emailed link with no ELD involvement at all, which is how owner-operators and mixed fleets run. ELD in-cab delivery is better when it is available because it puts the plan next to the dispatch the driver is already reading, but it is not a requirement.

Will this conflict with our fuel card's own savings reporting?

It will probably disagree with it, and that is useful. Card vendors report savings they calculate themselves against a baseline they choose, with no independent verification. Per-transaction reconciliation compares each actual purchase against a specific alternative that was available on that route at that time. When the two numbers differ, the reconciled one is the one you can audit line by line.
