Fleet maintenance
Fleet maintenance planned from real service history.
Generic intervals don’t know how your vehicles are driven. CarFai builds each vehicle’s maintenance plan from its own service records and diagnostic data, schedules the next service to a real date, and reminds you before insurance, registration or inspection runs out.

The problem
Why fleet maintenance slips
Service history is scattered
Invoices sit with different drivers, garages and folders. When a vehicle needs work, nobody knows when the brakes or tires were last done.
Breakdowns cost more than service
A van off the road means a lost day, a towing bill and an urgent repair at full price. Most breakdowns had warning signs.
Renewals slip through
Insurance, registration and inspection dates are spread across vehicles. One missed date can mean a fine or a vehicle that can’t legally be driven.
How it works
From invoices to a maintenance plan
- 01
Build the history
Drivers photograph service and repair invoices. CarFai reads them and adds each job to the vehicle’s history.
- 02
Plan from real data
CarFai combines that history, the manufacturer’s intervals and the way the vehicle is actually driven to date each upcoming service.
- 03
Act before it breaks
Managers see what is due across the fleet and plan the work before a breakdown forces it.
What you get
Less downtime, fewer surprises
Service dates, not vague intervals
Each upcoming service gets a real date, built from that vehicle’s own records.
OBD2 diagnostics in plain language
Connect a standard OBD2 adapter and fault codes come back explained, not as codes to search online.
Renewal reminders
Insurance, registration and inspection dates are read from scanned documents and surfaced before they expire.
Complete service history
Every invoice stays attached to its vehicle, ready when a garage, an auditor or a buyer asks.
History that survives driver changes
Vehicles belong to the organization, so their records stay when a driver leaves.
Maintenance cost per vehicle
Service and repair spending is tracked per vehicle, so you can see when a vehicle costs more to keep than to replace.

Questions fleet managers ask
Do we need an OBD2 adapter in every vehicle?
No. Maintenance planning works from service invoices alone. An OBD2 adapter adds live diagnostic data and plain-language fault codes for the vehicles that have one.
Which OBD2 adapters work with CarFai?
Standard Bluetooth OBD2 adapters based on the common ELM327 protocol, which covers most adapters sold for cars and light vans.
How does CarFai know when service is due?
It reads the vehicle’s past service invoices, combines them with the manufacturer’s intervals and the way the vehicle is driven, and schedules the next service to a date.
Can we record work done at different garages?
Yes. Any invoice or repair order can be photographed and added to the vehicle, whichever garage did the work.
What happens to the history when a driver leaves?
It stays. Vehicles belong to the organization, not the driver, so the full maintenance and cost history follows the vehicle to its next driver.
