Transportation ERP for fleets that need to run profitably
Transport operators manage expensive assets — trucks, trailers, drivers — that only earn money when moving loaded. Every empty kilometre, unplanned breakdown and unbilled detention charge comes straight off the bottom line.

Context
ERP in transportation
A transportation ERP links trips, costs and maintenance to each vehicle, so you know which routes, customers and assets are profitable.
01Operational challenges
What usually breaks before the ERP project starts
01
Cost per vehicle unknown
Fuel, tolls, repairs and driver costs not allocated to vehicles or trips.
02
Reactive maintenance
Breakdowns instead of planned service intervals.
03
Driver compliance
Licences, medicals and hours tracked on paper.
04
Billing leakage
Detention, waiting time and extra stops not billed.
02Core flows
How the ERP should handle each part of the business
- Sales flow
- Rate agreements by customer and lane; trips billed with accessorial charges.
- Procurement
- Fuel cards, tyres, parts and repairs purchased and allocated to vehicles.
- Inventory
- Spare parts and tyres in the workshop store.
- Warehouse
- Workshop parts store and issue to work orders.
- Accounting
- Cost per kilometre, per vehicle and per trip; asset depreciation.
- CRM
- Shipper relationships and contract renewals.
03Industry workflows
Workflows specific to transportation
01
Trip management
Trips planned with vehicle, driver, stops and charges.
02
Preventive maintenance
Service scheduled by distance, hours or time.
03
Fuel reconciliation
Fuel card transactions matched to vehicles and trips.
04
Driver documents
Licence and certification expiry alerts.
04 — Reporting
Reports that should come out of the system, not a spreadsheet
- Revenue and cost per vehicle
- Empty kilometre ratio
- Maintenance cost per vehicle
- Fuel efficiency
- Driver compliance status
- Unbilled accessorials
05 — Compliance
Compliance considerations
Driver hours-of-service rules, vehicle inspections and licensing vary by country. Recording documents and maintenance supports compliance audits.
Regulatory requirements vary by jurisdiction. We configure the system to support your obligations; confirm specific rules with your auditor or compliance advisor.
06 — Integrations
Systems the ERP needs to talk to
Telematics and GPS, fuel card providers, ELD/tachograph systems, and TMS tools are key integrations.
07AI opportunities
Where AI is genuinely useful here
Practical uses that sit on top of clean ERP data. None of them replace getting the core transactions right first.
01
Receipt capture
Read driver expense receipts and allocate to trips.
02
Maintenance prediction hints
Flag vehicles with rising repair frequency.
03
Load document extraction
Pull booking details from rate confirmations.
08ERP modules
Modules a typical deployment includes
- M01Fleet
- M02Maintenance
- M03Sales / Billing
- M04Purchasing
- M05Inventory
- M06Accounting
- M07HR
- M08Documents
09Roadmap
Implementation roadmap
- 01
Fleet master
Vehicles, drivers and documents recorded.
- 02
Trips and billing
Trip records and invoicing live.
- 03
Costs and maintenance
Fuel, repairs and service schedules.
- 04
Telematics
Automatic distance and location data.
10Common mistakes
Mistakes we see repeatedly
01
Costs not linked to vehicles
Without allocation, profitability per asset is unknown.
02
Manual odometer entry
Use telematics data where possible.
03
Ignoring accessorials
Configure billing for waiting, detention and extra stops.
04
Maintenance outside the system
Workshop records belong with the vehicle history.
