InvoiceFlow for Independent Taxi & Transport Drivers: Complete Billing Guide

The invoicing system built for independent drivers, private hire vehicles, and personal transport services

Independent drivers who go beyond platform apps face a billing responsibility that the platforms previously handled automatically. Corporate accounts, medical transport clients, airport regulars, and recurring personal clients all need professional invoices to process payments on their end.

InvoiceFlow handles every independent driver billing type from one Android app. This guide covers how to build your transport billing system.

Building Your Rate Card in InvoiceFlow

Before you can invoice consistently, your rates need to be defined and stored. Build your service catalog in InvoiceFlow with every rate you charge:

Standard transport rates to define:

Base rate per mile (or flat rate by zone/destination)
Airport runs (named destinations, flat rates)
Early morning surcharge (before 6 AM)
Late night surcharge (after 10 PM)
Rush/same-hour booking surcharge
Waiting time rate (per 15-minute increment, after free time)
Additional passenger charge (per person over standard)
Extra luggage/oversized baggage charge
Medical appointment transport (accessibility or priority rate)
Fuel surcharge (percentage of total fare)

Having these pre-built means every invoice pulls from the same rate card. No guessing, no inconsistency, no fare disputes.

Per-Ride Invoicing

Invoice Flow app invoice editor of a private hire driver — a monthly corporate account with city journeys and airport transfers and a cost-centre reference in custom fields — A whole month of executive journeys and airport transfers on one invoice — cost-centre reference in custom fields for their accounts team.

For individual clients who pay by ride, send the invoice before they leave the vehicle or immediately after drop-off:

“Transport Services — [Client Name] — June 6, 2026: Pickup: [Address] | Destination: O’Hare International Airport, Terminal 1 Departure: 06:45 AM | Distance: 23 miles Airport Run Rate: $78.00 Early Morning Surcharge (before 6 AM): $18.00 Fuel Surcharge (6%): $5.76 Total: $101.76 Payment: [Method] — Due upon receipt”

Sending the invoice at drop-off means it reflects your actual price, the client has documentation, and you do not have to reconstruct the fare later from memory.

Monthly Corporate Account Invoicing

Corporate clients — law firms, consulting companies, executives who use you regularly — expect a monthly invoice they can process through their AP system. Each run in the month appears as a line item.

“Transportation Services — [Company Name] — June 2026: June 2: Employee pickup, office → O’Hare T3, 7:15 AM: $78.00 + $18.00 (AM surcharge): $96.00 June 4: Client airport pickup, O’Hare T1 → hotel, 3:30 PM: $82.00 June 7: Executive downtown circuit (4 stops): $112.00 June 11: Late evening hotel pickup, 11:00 PM: $78.00 + $18.00 (PM surcharge): $96.00 [… full month’s runs] Monthly subtotal: $1,340.00 Fuel surcharge (6%): $80.40 Total: $1,420.40 Payment Terms: Net-15 Account: [Company] #CORP-CHI-001”

Set up a recurring monthly invoice template in InvoiceFlow for each corporate account. Fill in the month’s runs and send on the first business day of the following month. Payment arrives reliably within net-15 terms.

Medical Transport Invoicing

Invoice Flow app recurring invoices of a private hire driver — a monthly corporate executive account and a school transport contract generating automatically — Corporate and school-run contracts on a monthly cycle — the stable accounts bill themselves.

Medical appointment transport clients often need documentation that supports reimbursement through insurance, Medicaid, PACE programs, or other coverage:

“Medical Transportation Services — [Patient Name] — [Date]: Pickup: [Home Address] Destination: [Hospital / Clinic Name], [Department] Appointment Time: [Time] Transport Type: [Standard / Wheelchair accessible] Driver certification: NEMT [if applicable] Outbound trip: $55.00 Waiting time at appointment ([X] hours × $24/hr): $[Amount] Return trip: $55.00 Total: $[Amount] Insurance/Program Reference: [Number if applicable]”

Include the appointment location, appointment time, and transport type. Medical billing clients use this documentation to file reimbursement claims. Complete documentation means faster reimbursement for them and a stronger client relationship for you.

Waiting Time Billing

Set a clear waiting time policy and include it on your invoices:

Free time: 10 minutes at pickup locations, 0 minutes at medical appointments (waiting time begins at appointment check-in). Waiting time rate: $12.00 per 15-minute increment.

“Waiting Time — Medical Appointment — [Clinic Name]: Appointment duration: 1 hour 45 minutes (105 minutes) At $12.00 per 15 minutes: 7 increments: $84.00”

Clients who understand that waiting time is billed plan their appointments around it or approve the charge because the documentation is clear.

Fuel Surcharge

Apply a fuel surcharge consistently to all invoices — individual and corporate:

“Fuel Surcharge (6% of total transport): $5.76”

Review your fuel surcharge percentage quarterly based on average fuel costs. For a driver covering 2,000+ miles per month, a consistent 6% surcharge applied to all fares recovers significant annual fuel expense.

Airport and Special Event Billing

Invoice Flow app documents of a private hire driver — a corporate monthly account, a school transport contract, an event chauffeur booking and an airport transfer receipt — Corporate accounts, a school contract, an event booking and a one-off airport transfer — every revenue stream on record.

For airport runs and special events (weddings, corporate events, sports), flat-rate billing is cleaner than per-mile:

“Airport Transport — O’Hare International — June 8, 2026: Pickup: [Address] → O’Hare Terminal 3 Flight: [Airline] [Flight Number] Flat rate: $78.00 Extra luggage (3 bags): $10.00 Fuel surcharge: $5.28 Total: $93.28”

Including the flight number or event details personalizes the invoice and documents the booking basis for the client.
