Is Your Car Rental Business Facing These Problems?
Many Cars, Unknown Profit Per Car
You only know total revenue, but don't know which car is dragging down costs.
Skyrocketing Repair & Insurance Costs
Maintenance costs keep rising, eating away your profits.
Depreciation Pressuring the Budget
Depreciation deductions don't align with actual vehicle usage.
Multiple Revenue Channels
Revenues from OTAs, platforms, and the front counter are all mixed up.
Insufficient Cash Flow
Liquidity disappears because cash is tied up in maintenance.
Cannot Get Loans for More Cars
Financial statements don't reflect your true debt repayment capacity.
Why Do Car Rentals Need Specialized Accounting?
The car rental business has very high fixed costs including depreciation, insurance, maintenance, and leasing interest. It also receives income from a variety of channels. Without a proper data recording system separated by vehicle (Cost Center), you will have no way of knowing exactly which car, model, or platform is truly generating profit for your business.

Manage Your Fleet
With Financial Data
The make-or-break point for car rentals is vehicle-related decisions. We use in-depth accounting data to answer questions executives face daily:
- Which car generates the highest profit, and which should be retired?
- Is it better to Buy new cars or use Leasing?
- What Fleet Utilization percentage is needed to hit break-even?
- How should taxes be planned when selling scrapped cars or buying new ones for the portfolio?
Fleet Costs We Monitor For You
Seamless Management of Multi-Platform Revenue
Today’s car rental businesses often receive bookings through multiple channels: websites, LINE OA, P2P platforms (like Roddaitang.com), long-term corporate clients (Siam.Rent), OTAs, as well as Walk-in customers.
Our accounting system helps clearly separate and analyze the performance of each channel so you know exactly where to allocate your marketing budget.
Fully Booked but No Cash Left?
Your Utilization rate might be sky-high, but net profits vanish because they're swallowed by hidden costs, repairs, and inefficient fleet management. Our CFO Advisory service will dissect your statements and turn profits around.
Preparing to Expand Your Fleet?
Before buying more cars, you must analyze Fleet ROI and debt burdens confidently. We help prepare beautiful financial statements to enhance your Debt Service Coverage Ratio (DSCR) through our Loan Advisory service.

What Type of Car Rental Businesses Is This For?
Car Rental Company in Chiang Mai
The management aimed to expand their fleet with Sedan cars due to high rental demand. However, when our CFO team set up the accounting system and conducted a Profit per Vehicle analysis, they discovered that SUV groups—despite slightly lower rental rates—generated higher margins and had significantly lower maintenance costs. The business shifted its investment focus to SUVs, resulting in an immediate 25% growth in Net Profit (EBITDA) that year.
Frequently Asked Questions (FAQ)
How is vehicle depreciation calculated for car rentals?
Generally, depreciation can be deducted up to 20% per year (based on a 5-year useful life), but tax law limits on passenger car values must also be considered.
Do car rental services need to register for Value Added Tax (VAT)?
Yes, providing car rental services (without a driver) is subject to VAT if revenue exceeds 1.8 million THB per year.
When buying new cars, should we pay cash, use financing, or lease?
It depends on tax policies and liquidity. If you want to deduct the full rental fee as a corporate expense, an Operating Lease is often more advantageous from a tax perspective.
What do financial statements need to look like for a car rental to get a loan?
Banks focus on Cash Flow and EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) to verify you have enough cash remaining to service the vehicle loans.
At what age should a car be replaced or retired?
Financially, a car should be retired when the 'Maintenance Cost + Cost of Downtime' begins to exceed the 'Depreciation' of a new car. Our accounting team can calculate this exact intersection point.
