Setting Up Your Books: Chart of Accounts for Detailers
The categories that organize your financial life. Get this right once and everything else is easier.
A chart of accounts is just a list of categories for your income and expenses. Setting up the right categories from the start means consistent tracking, meaningful reports, and easy tax preparation. Copy the detailing-specific chart in this lesson.

What Is a Chart of Accounts?
A chart of accounts is simply the list of categories you use to organize your financial transactions. Every time money comes in or goes out, it gets assigned to a category (or "account"). These categories then feed into your financial reports — your P&L, balance sheet, and tax forms.
Think of it like folders for your finances. Just as you might organize your computer files into folders like "Photos," "Documents," and "Work," you organize your financial transactions into accounts like "Service Revenue," "Supplies," and "Vehicle Expenses."
Get the chart of accounts right, and:
- Your P&L statement is meaningful and useful
- Tax preparation is straightforward
- You can track trends in specific expense categories
- Your bookkeeper and CPA know exactly where things go
Get it wrong, and:
- Everything ends up in "Miscellaneous" or "Other"
- You can't tell where your money is actually going
- Tax time requires hours of re-categorization
- Your CPA charges you more for the cleanup
The Five Types of Accounts
Every account in your chart falls into one of five types:
1. Assets
Things your business owns or is owed. For a mobile detailer:
- Business checking account
- Business savings account
- Accounts receivable (money clients owe you)
- Equipment (polishers, pressure washer, etc.)
- Vehicle (if owned by the business)
2. Liabilities
Things your business owes. For a mobile detailer:
- Credit card balance
- Business loans
- Vehicle loan (if applicable)
- Sales tax payable (if you collect sales tax)
3. Equity
The owner's stake in the business. For most sole proprietors and single-member LLCs:
- Owner's equity / capital
- Owner's draws (money you take out)
- Retained earnings (accumulated profits)
4. Income (Revenue)
Money coming in from your services:
- Service revenue (detailing services)
- Product sales (if you sell products)
- Tips
5. Expenses
Money going out to run the business. This is where most of your categories live.

How to Use This Chart
In Wave or QuickBooks
- Go to Settings → Chart of Accounts
- Delete or rename the default accounts you don't need
- Add the accounts listed above that apply to your business
- Assign the correct account type (Asset, Liability, etc.) to each
- Use account numbers if the software supports them (helps with organization)
In a Spreadsheet
- Create columns: Date, Description, Category, Amount
- Use the category names above for the "Category" column
- Be consistent — always use the same category name for similar expenses
- Create a summary sheet that totals each category monthly
Categorization Rules
The key to useful books is consistent categorization. Here are rules to follow:
When to Use "Chemicals & Products" vs. "Tools & Equipment"
Chemicals & Products (COGS): Anything consumed on jobs. If it gets used up and needs to be repurchased regularly, it's COGS. Polish, compound, coating, towels that wear out, pads that degrade.
Tools & Equipment (Operating Expense): Durable items that last for months or years. Polishers, pressure washers, vacuums, lights, carts.
When to Split Revenue Categories
Split revenue categories if you want to track which services make the most money. If you don't care about that level of detail, use a single "Service Revenue" account.
Recommendation: At minimum, separate regular service revenue from dealer/fleet work — they have different margins and cash flow patterns.
When to Use "Miscellaneous"
Rarely. "Miscellaneous" should be less than 5% of your total expenses. If you're putting a lot into miscellaneous, you need more specific categories. A CPA hates seeing a big "Miscellaneous" number — it's a red flag that books aren't well-organized.
Personal vs. Business: The Split Rule
For expenses that are partially personal (phone, internet, vehicle if also used personally), estimate the business percentage and only record that portion. Don't put your entire $150 phone bill as a business expense if 40% of usage is personal.
Keeping It Simple vs. Getting Granular
You might look at this chart and think "that's a lot of categories." Here's how to think about it:
Start simple. If you're just beginning, use fewer categories:
- Service Revenue (all services combined)
- Chemicals & Supplies
- Vehicle Expenses
- Insurance
- Software & Phone
- Marketing
- Other Expenses
Add granularity as you grow. When you want to understand "why did my vehicle expenses spike this month?" it helps to have separate categories for fuel, repairs, and insurance.
Match your curiosity. If you don't care about tracking training expenses separately, lump it into "Other." But if you want to know how much you've invested in education, make it its own category.
The goal is useful information, not complexity for its own sake.
Why Categories Matter: A P&L Example
Common Mistakes
→ Miscellaneous should be under 5% of expenses. If something happens regularly, create a category for it. 'Miscellaneous' is for true one-offs.
→ Pick exact names and stick to them. 'Chemicals,' 'Chemical Supplies,' and 'Detailing Chemicals' should all be the same account. Consistency is everything.
→ Start simple. You can always add categories later. If a category has only 1-2 transactions per year, it probably doesn't need to be separate.
→ COGS (chemicals, consumables) directly ties to jobs. Operating expenses (insurance, phone) are overhead. Separating them gives you gross margin — a key metric.
→ Money you pay yourself is an equity transaction, not an expense. It should reduce Owner's Equity, not show up on your P&L as an expense.
Set up your chart of accounts this week. Whether you're using Wave, QuickBooks, or a spreadsheet, take 30 minutes to create categories based on this lesson. Then commit to using them consistently for every transaction going forward.
Detaild tracks revenue by service type automatically. When expense tracking launches, you'll be able to export data directly into the categories your bookkeeping system uses.
Ask your CPA to review your chart of accounts before the end of your first full business year. They may suggest adjustments that make tax prep easier or catch categorization errors before they compound.
Frequently Asked Questions
Do I need account numbers (1000, 2000, etc.)?
They're optional but helpful. Account numbers group related accounts together (all expenses in the 6000s, for example) and make sorting and finding accounts easier. QuickBooks uses them; Wave doesn't require them. Use them if your software supports them.
Can I change my categories later?
Yes, but it's easier to add new categories than to re-categorize old transactions. If you change 'Chemicals' to 'Detailing Supplies,' you may need to go back and re-assign old transactions for consistent reporting. Set up thoughtfully from the start.
Should I separate income by service type?
It depends on what you want to learn. If you want to know which services drive the most revenue or have the best margins, separate them. If you just want a total revenue number, combine them. At minimum, separate dealer/fleet work from retail — they're different business dynamics.
What's the difference between 'Supplies' and 'COGS'?
COGS (Cost of Goods Sold) are direct costs of delivering a service — chemicals, consumables used on specific jobs. 'Supplies' in operating expenses would be general supplies not tied to a specific job — office supplies, general-use items. For detailing, most supplies are COGS because they're used on jobs.
Do I need all these accounts if I'm just starting out?
No. Start with the simplified list in the 'Keeping It Simple' section. You can always add accounts as your business grows and you want more detail. Better to start simple and expand than to set up 50 accounts you'll never use.
