Every fleet organisation we've worked with has a version of the same problem. Fleet operations produces a cost per mile figure. Finance produces a fleet cost total. When you divide finance's total by operations' mileage, you get a number that's materially different from what operations calculated. Both teams defend their figures. Neither is wrong. They're just measuring different things, using data from different systems, over slightly different time periods.
The gap between operations and finance fleet cost figures is almost always structural rather than a result of errors. It comes from three specific mismatches that occur systematically across nearly every organisation.
Timing mismatch. Operations reports on cash accruals -- what was spent in the period. Finance reports on accruals accounting -- what cost was incurred in the period, adjusted for timing differences. A major maintenance invoice received in December but relating to November work will appear in operations' November figure and finance's December figure. Neither is wrong. They're using different accounting bases.
Scope mismatch. Operations tracks the vehicles. Finance tracks all fleet-related expenditure, which includes costs that operations doesn't see -- driver training reimbursements, fleet management software subscriptions, internal staff costs attributed to fleet administration. Operations' cost per mile denominator is vehicles; finance's total includes everything the company spends on having and running a fleet.
Mileage mismatch. Operations' mileage figure comes from telematics or manual records. Finance doesn't independently track mileage at all -- it uses whatever operations provides. But if the mileage data was sent to finance quarterly and operations has since corrected it, the two figures diverge without either team being aware.
The immediate consequence of misaligned fleet cost figures is credibility loss. When the fleet director and the finance director present different numbers in the same board meeting, neither is taken seriously. The board receives conflicting data and makes either no decision or the wrong decision.
The deeper consequence is that the organisation can't make sound fleet investment decisions. Should you replace the oldest cohort of vehicles? Extend the lease on the current fleet? Move to a different maintenance contract? All of these decisions depend on reliable total cost data. If you don't have it, you're making guesses dressed as analysis.
"We've sat in meetings where the fleet director's number was £180 per vehicle per week and the finance director's was £240. Same vehicles. Same period. Thirty minutes of that meeting was spent on the gap, none of it on the decision." — ExoFleets Team
Getting operations and finance to agree on fleet cost figures requires addressing each of the three mismatches directly.
For the timing mismatch, the fix is agreeing on a single accounting basis for fleet reporting and sticking to it consistently. We recommend accruals accounting for all fleet cost tracking -- it gives a more accurate picture of what the fleet actually cost in a period and reduces the volatility from invoice timing. This requires finance to share accruals data with fleet operations, which means the fleet management system needs to accept finance-sourced cost data, not just invoice data.
For the scope mismatch, the fix is building a definitive list of what's in and out of "fleet cost." Write it down. Every cost category, explicitly included or excluded. Fleet software subscription -- in or out? Driver training -- in or out? Head office fleet manager salary -- in or out? This sounds administrative but it's foundational. You can't reconcile figures whose scope has never been agreed.
For the mileage mismatch, the fix is establishing a single source of mileage data -- telematics, ideally -- that both teams use. The figure that goes to finance is the same figure operations is managing against. If it changes, both teams are notified simultaneously.
The underlying principle in all of this is that fleet cost reporting should have a single source of truth: one system that both operations and finance treat as authoritative, rather than two systems that are periodically reconciled. Fleet ERP sits between the operational data (telematics, maintenance systems, fuel cards) and the financial reporting (ERP, management accounts) and acts as that single source.
When it's working correctly, the fleet director and the finance director are looking at the same number before the board meeting, not comparing notes and arguing about whose figure is right. That shift -- from reconciliation to alignment -- is genuinely transformative for the quality of fleet investment decisions.
