Unbilled detention and accessorials tied to undocumented or inaccurate driver time logs
Definition
Petroleum and fuel carriers often have contractual rights to charge detention or accessorial fees when drivers wait at terminals or customer sites, but if time on site is not accurately captured in HOS or telematics records, these billable items are missed. Fleet compliance and telematics vendors emphasize precise time and location tracking and automated reporting, which is explicitly used to support billing and prove on-site times; without this, time-based charges go unbilled.[4][6][7]
Key Findings
- Financial Impact: $10,000–$50,000 per year in missed detention and accessorial revenue for a mid‑sized wholesale petroleum fleet, based on typical detention rates and under-billing reported in fleet analytics use cases.
- Frequency: Weekly
- Root Cause: Driver hours and arrival/departure times are often recorded only in paper logs or loosely in dispatch notes that are not tied into billing workflows. Petroleum-focused TMS and fleet management solutions promote real-time location and status tracking specifically for hazmat/fuel fleets to support accurate invoices and charge validation, indicating that unintegrated or inaccurate time tracking directly causes recurring revenue leakage.[4][6][7]

Financial Impact
$10,000–$30,000 annually in missed accessorial and delivery charges ($50–100/hour for retail fuel delivery) due to incomplete time documentation; high-volume locations with 1–4 hour unload times frequently unbilled • $10,000–$30,000/year in unbilled detention; delayed cash flow; potential contract penalties for under-invoicing • $10,000–$40,000 per year in conservative under-billing and unclaimed detention/accessorials on municipal contracts for a mid-sized petroleum carrier, plus hidden costs from staff time and legal/administrative effort needed when a contested invoice must be defended without clear time-log evidence.
Current Workarounds
Commodity Trader dispatcher logs approximate time in paper manifest; marine customer provides bill of lading with arrival time only; departure time left undocumented or estimated • Commodity Trader driver estimates wait time verbally to dispatcher; handwritten note on invoice or nothing recorded; construction site foreman unaware of billing implications • Commodity Trader driver records approximate time on delivery ticket or forgets; agricultural site uses no formal time-in/time-out system; billing based on assumed standard delivery window
