Sub accounts let you track different types of payables separately

A sub account in QuickBooks Online is an account nested under a parent account in your chart of accounts. For Accounts Payable, sub accounts let you organize what you owe by vendor type, location, or payment method instead of lumping everything into one AP account. When you create a sub account, transactions posted to it roll up into the parent account on your balance sheet, so your totals stay correct while your reports show more detail.

You create sub accounts in the Chart of Accounts section, and the process takes less than a minute per account. Once created, you pick the sub account when you enter a bill or expense, and QuickBooks tracks the balance separately while keeping your overall AP balance accurate.

Key Takeaways

  • Sub accounts for AP are created in Chart of Accounts and appear indented under your main Accounts Payable account in reports and transaction entry.
  • You can organize sub accounts by vendor category, location, or any other breakdown that matches how you track spending.
  • Transactions posted to a sub account automatically roll up into the parent AP account, so your balance sheet total remains correct.
  • Once a sub account exists, you select it when entering bills or expenses, and it appears as an option in the account dropdown.

Access the Chart of Accounts and find your AP account

Open QuickBooks Online and click Accounting in the left sidebar. Then click Chart of Accounts. You will see a list of all your accounts organized by type — Assets, Liabilities, Equity, Income, and Expenses.

Scroll down to the Liabilities section and find your Accounts Payable account. It is usually named "Accounts Payable" or "AP" and has an account number (often 2000 or 2100 depending on your chart setup). This is the parent account under which your sub accounts will sit.

Create a new sub account from the Chart of Accounts

Click the New button in the top left of the Chart of Accounts page. A dropdown menu appears with account type options. Select Account to create a new account.

A form opens with fields for account details. In the Account Type dropdown, select Accounts Payable. Then check the box labeled Is sub account. A new dropdown field appears asking you to select the parent account — choose your main Accounts Payable account from the list.

Enter a Name for the sub account that describes what it tracks. Examples include "AP — Vendors," "AP — Contractors," "AP — Utilities," or "AP — Office Supplies." You can also add a number in the Account Number field if your company uses a numbering system (for example, 2100-01, 2100-02). Leave the Description field blank or add a note about what this sub account covers.

Click Save and Close. The sub account now appears in your Chart of Accounts, indented under the parent Accounts Payable account.

Repeat the process for each sub account you need

If you need multiple sub accounts — for example, one for vendors, one for contractors, and one for utilities — repeat the steps above for each one. Each sub account must have the same parent (your main Accounts Payable account) and a unique name.

You can create as many sub accounts as your business structure requires. There is no limit, but keeping the number manageable (typically five to ten) makes reports easier to read and account selection faster when entering transactions.

Use sub accounts when entering bills and expenses

When you enter a bill in QuickBooks Online, the Category Details section shows an Account dropdown. Click that dropdown and you will see your main Accounts Payable account and all its sub accounts listed below it, indented slightly. Select the sub account that matches the type of bill you are entering.

When you write a check or record a payment, QuickBooks also asks which account to post the payment against. Select the same sub account you used when you entered the bill. The payment reduces the balance of that specific sub account.

Your reports — including the Balance Sheet and Accounts Payable Aging Report — will show the total across all AP sub accounts on the main Accounts Payable line, but you can drill down to see the breakdown by sub account if you need detail.

Edit or delete sub accounts if your structure changes

To edit a sub account, go to Chart of Accounts, find the sub account in the list, and click the three-dot menu on the right side of that row. Select Edit. You can change the name, description, or account number. Click Save and Close.

To delete a sub account, use the same three-dot menu and select Delete. QuickBooks will only let you delete a sub account if it has a zero balance. If the sub account has transactions, you must either move those transactions to a different account or reconcile and clear the balance first. If you no longer want to use a sub account but it has a balance, you can mark it as Inactive instead of deleting it — this hides it from dropdown lists but keeps the history intact.

Frequently Asked Questions

Do sub accounts change how my balance sheet looks?

No. Your balance sheet shows only the total of the parent Accounts Payable account, not the individual sub accounts. Sub accounts exist to organize your data and make reports more detailed, but they do not change the overall liability total that appears on your financial statements.

Can I convert an existing account into a sub account?

No. Once an account is created, you cannot change it to a sub account or change its parent. If you need to restructure, you must create a new sub account and move transactions manually or through a journal entry. For this reason, it is worth planning your AP sub account structure before you start entering bills.

What happens if I post a bill to the parent AP account instead of a sub account?

The bill still records correctly and your AP total is still accurate. However, that transaction will not appear in the sub account breakdown. If you notice this after the fact, you can edit the bill and change the account to the correct sub account, and the change updates automatically.

Can I use sub accounts for other liability accounts besides AP?

Yes. You can create sub accounts under any liability account — for example, sub accounts under Payroll Liabilities or Sales Tax Payable. The process is identical: mark the account as a sub account and select the parent account when you create it.
