Core Capabilities

Everything your fleet needs.
Nothing it doesn't.

Driver Experience

Three taps. Logged. Done.

Drivers log in once via SMS OTP and stay authenticated for 6 days. The app shows exactly one action at a time — matched to where they are in the day.

1

Start Day

Select the assigned truck, enter the opening odometer reading, snap a photo. Session opens and the driver is ready to roll.

Odometer photoSelfie captureAuto check
2

Confirm Orders

View assigned orders sorted closest-to-depot first. Capture recipient signature and invoice photo. GPS-stamped from truck telemetry — no phone location permission needed.

Digital signatureInvoice photoGPS stamp
3

Log Fuel Fill

Enter litres and odometer at the pump, photograph the receipt. Anomaly checks fire instantly — overfills and suspicious patterns flag silently to admin.

Receipt photoCost per litreInstant validation
4

End Day

Enter the closing odometer, submit a closing photo. Session closes, distance is calculated, and the audit trail is complete.

Anomaly Detection

Your silent fraud watchdog. Always on.

Two independent detection layers run 24/7 — one checking driver session logs, one watching live telemetry from every device.

📋

Session-Based Detection

Runs synchronously when drivers submit logs. Catches manual fraud and suspicious patterns immediately.

  • Odometer went backwards
  • Fill exceeds tank capacity (overfill)
  • Suspiciously small fill (< 5 L)
  • More than 2 fills in one session
  • Excess fuel consumption vs truck rating
  • Session left open overnight (auto-close)
📡

Device Telemetry Detection

Fires on every telemetry message — even when no session is active. Catches what drivers can't fake.

  • Vehicle moving with ignition off
  • Engine started with no active session
  • Fuel level rose with no logged fill
  • Fuel drained while truck is parked
  • Engine overheat (> 105 °C)
  • Battery critically low voltage

🟣 THEFT

Immediate push notification + tab flash

The most severe events indicating possible theft or unauthorised vehicle use. Triggers browser push notifications and a flashing tab title until dismissed.

  • Movement without ignition (tow or push)
  • Engine on with no TankWize session
  • Fuel fill not logged in the system
  • Fuel drain while truck is parked

🔴 CRITICAL

Red alert banner — attend promptly

Vehicle or data integrity issues requiring prompt attention. Shown in the red alert banner on all admin pages.

  • Engine coolant temperature > 105 °C
  • Battery voltage critically low
  • Odometer reading went backwards
  • Fuel overfill beyond tank capacity

🟡 WARNING

Amber badge — review when convenient

Patterns that should be reviewed but don't require immediate action. Flagged on the session and surfaced in the sessions filter.

  • Vehicle speed above 120 kph
  • DTC / check engine fault codes
  • Zero km driven in a full session
  • Suspicious fuel fill pattern

Platform Portal

Run any number of fleets from one interface.

The Super Admin platform gives TankWize operators complete cross-tenant oversight — with the ability to dive into any company's fleet or recruitment portal using a short-lived scoped token.

🏢
Cross-tenant company dashboard
All companies in one table — driver counts, truck counts, sessions today, and anomaly flags at a glance.
🎨
White-label theme editor
Live colour picker for all 6 brand tokens per company. Preview updates instantly before saving.
🔑
Scoped company access
Click Manage on any company to receive a 1-hour scoped JWT. The full admin portal loads with that company's data and branding — zero code duplication.
📟
Device management & log viewer
All GPS devices in one list. Inline log viewer with date range, pagination, and CSV export. Assign devices to trucks from the edit drawer.
🏷️
Per-company module selection
Enable Fleet, Recruitment, or both per company. The admin portal nav adapts automatically — fleet companies see fleet nav, recruitment companies see applicant and training nav.
Recruitment Module

Hire qualified drivers.
Onboard them fast.

The TankWize recruitment module gives companies a branded job portal where candidates apply, upload documents, and complete training — all before their first day on the road.

📋
Job Listings
Post listings with work type, remote policy, experience level, and industry tags. Candidates filter and apply via jobs.tankwize.com — no account needed to browse, simple sign-up to apply.
👤
Applicant Profiles
Applicants build a verified profile — ID document, CV, profile photo, LinkedIn, portfolio URL, and contact details — with a 5-star rating that builds over time.
🎓
Training & Onboarding
Applicants book training sessions before hire. Admin confirms bookings with a Google Calendar event ID — completions are tracked on each profile.
👥
Employee Management
Once hired, applicants become employees. Track contract status, training completions, and performance history — with automated quarterly survey reminders so no one falls through the cracks.

Security & Auth

Passwordless. Role-enforced. Audit-logged.

Every action in TankWize is authenticated, authorised, and logged. Drivers never need a password. Admins can't see other companies' data.

📱
Passwordless SMS OTP
6-digit codes via Twilio. Only numbers already in the database can request an OTP — unknown numbers are blocked before any SMS is sent.
🔄
Silent JWT refresh
15-minute access tokens in production. The Axios client silently refreshes on 401 — drivers stay logged in for 6 days without interruption.
🏢
Company-scoped data isolation
All queries filtered by companyId from the JWT payload. There is no API path that can return another tenant's data.
📋
Full audit trail
Every admin action — user creation, truck edits, odometer corrections — is recorded with actor, timestamp, and human-readable description.
📸
Direct cloud photo uploads
Photos never touch the API server. Presigned R2 URLs route uploads from device directly to Cloudflare storage.
