How to Connect ADP to QuickBooks Online

Connecting your ADP payroll to QuickBooks Online eliminates one of the most tedious manual tasks in bookkeeping: the post-payroll journal entry. Once configured, it saves time, reduces data entry errors, and provides a more accurate, real-time view of labor costs. This guide will walk you through the entire setup process, from pre-integration preparation to final account mapping, so you can get it right the first time.

Why Connect ADP and QuickBooks Online?

The primary benefit of connecting ADP and QuickBooks Online is automation. After you run payroll, you no longer need to manually calculate and enter a journal entry to record wages, taxes, and deductions. The integration creates and posts this entry for you, turning a 15-minute task into a zero-minute task. This time-saving adds up significantly over a year.

Beyond convenience, the connection dramatically improves accuracy. Manual data entry is prone to transposition errors, misplaced decimals, and simple typos. A single incorrect digit can throw off your books and lead to a frustrating search during bank reconciliation or tax preparation. The automated data transfer from a tool like ADP RUN ensures that the exact amounts for gross wages, employee and employer taxes, and various deductions are recorded in the correct accounts every single time.

This leads to smoother bank reconciliations. The total payroll debit withdrawn from your bank account will have a corresponding and detailed journal entry already waiting for it in QuickBooks. This makes matching bank transactions to your accounting records much faster because the debits for tax payments and direct deposits will be clearly explained by the synced journal entry.

Finally, better data leads to better decisions. When payroll information is synced instantly, business owners and management get an up-to-date look at their largest expense—labor. With accurate, timely information in your accounting system, you can generate financial reports like the Profit & Loss statement with confidence and get a true picture of your company's profitability and cash flow without delay.

Before You Begin: A Quick Pre-Integration Checklist

A few minutes of preparation before you start the connection process will prevent common frustrations and ensure a smooth setup. Don't skip these steps; they make the mapping process much easier.

• Confirm Administrator Access: You will need full administrator permissions for both your ADP RUN payroll account and your QuickBooks Online company file. Without these permission levels, you won't be able to authorize the connection between the two systems.

• Review Your Chart of Accounts: This is the most important preparatory step. Take a look at your Chart of Accounts in QuickBooks. Have you created all the necessary expense and liability accounts to properly categorize your payroll? You should have specific accounts ready, such as:

  • Expense Accounts: Gross Wages, Employer FICA Taxes, Employer FUTA Taxes, State Unemployment Insurance (SUI), and any company-paid benefit expenses like Health Insurance or Retirement Contributions.
  • Liability Accounts: Payroll Liabilities (a parent account), with sub-accounts for Federal Withholding Payable, Social Security and Medicare Payable, SUI Payable, and payables for any employee deductions like Health Insurance Payable, 401(k) Payable, or Wage Garnishments Payable.

  Organizing your accounts properly before mapping makes the process far more intuitive.

• Backup Your Data: While the ADP to QBO integration is reliable, it's always standard practice to back up your accounting file before connecting a new third-party application. QuickBooks Online Advanced plans include an online backup feature, or you can use a separate third-party backup app.

• Choose Your Timing Wisely: The ideal time to activate the General Ledger integration is immediately after processing a payroll run for a completed pay period. This creates a clean cutoff point and prevents any risk of syncing partial data or creating duplicate entries for a cycle that's already been recorded manually.

Step-by-Step: Connecting ADP RUN to QuickBooks Online

With your accounts reviewed and access confirmed, you're ready to make the connection. The process takes place almost entirely within the ADP RUN platform.

Step 1: Locate the General Ledger Sync Feature in ADP

Log in to your ADP RUN account. The interface may vary slightly, but you will generally find the General Ledger integration feature under a "Company" or "Settings" menu. Look for a section named something like “General Ledger,” “GL,” or “Accounting.” Inside this section, you will see an option to set up your accounting software export. Select an option that mentions QuickBooks Online.

Step 2: Start the Connection and Authorize QuickBooks

Once you initiate the setup, ADP will prompt you to connect to your QuickBooks Online account. A new, secure window will pop up, asking for your Intuit login credentials (the same ones you use for QuickBooks Online). This process uses a secure authentication standard (OAuth) that allows ADP to "talk" to your QBO file without ever storing your password.

After you log in successfully, Intuit will ask you to authorize ADP to access your company data. It will specify that ADP will be able to read your Chart of Accounts and write journal entries to your ledger. You must grant this permission to proceed.

Step 3: Configure Your General Ledger Settings

This is where you tell ADP how to post payroll data to QuickBooks. You’ll have a few important options that determine how the final journal entry will look.

• Post Dates: You must decide if the journal entry date in QuickBooks should correspond to the pay date or the pay period end date. Most accountants prefer using the pay date. This is because it aligns with a cash-basis view of the transaction and makes bank reconciliation easier since the journal entry date will match the date money actually leaves the bank. Using the pay period end date is more common for strict accrual accounting or when detailed job costing by period is a high priority.
• Entry Granularity: ADP usually provides two choices for how the journal entry is structured.
  • One Summary Journal Entry: This is the most common and highly recommended preference. ADP creates a single, clean journal entry that summarizes totals for a complete payroll run, keeping your General Ledger uncluttered.
  • Entry by Employee: A detailed breakdown that includes splits for each employee. This creates much longer and more complex journal entries. While it provides immense detail, it can make the General Ledger difficult to read. This is necessary in specific job costing scenarios where employee wage expenses have to be attributed directly.
• Enable Class or Location Tracking: If your company uses Class Tracking or Location Tracking in QuickBooks Online for departments, projects, or separate business units, you must enable it here. This allows you to map payroll expenses by a specific Class or location, which vastly improves departmental P&L reporting and financial analysis.

The Heart of the Integration: Mapping ADP Payroll Items to Your QuickBooks Chart of Accounts

This phase is where your preparation pays off. The ADP interface will present you with a list of every single payroll item—all earnings, taxes, deductions, and company contributions. For each item listed, you must select the corresponding account from your QuickBooks Chart of Accounts using a dropdown menu. Attention to detail here is essential for accurate financials.

Take your time and map each item methodically. It will look something like this:

ADP Payroll Item: Regular Earnings -> QuickBooks Account: 6000 · Gross Wages (Expense)

ADP Payroll Item: Employee Medicare Tax -> QuickBooks Account: 2100 · Payroll Liabilities: Medicare Payable (Liability)

ADP Payroll Item: Employer Medicare Tax Match -> QuickBooks Account: 6010 · Employer Payroll Taxes (Expense)

ADP Payroll Item: Federal Income Tax Withholding -> QuickBooks Account: 2100 · Payroll Liabilities: Federal Withholding Payable (Liability)

ADP Payroll Item: Employee Medical Deduction -> QuickBooks Account: 2120 · Medical Insurance Payable (Liability)

ADP Payroll Item: 401(k) Employee Deduction -> QuickBooks Account: 2130 · 401(k) Payable (Liability)

Common Mapping Mistakes to Avoid

A simple mistake in this phase can cause recurring issues. Be extra cautious about these common errors:

• Mapping Liabilities to Expense Accounts: Every employee withholding (taxes, benefit premiums, garnishments) is a liability for the company; you are holding that money until you pay it to the third party. Do not map these items to an expense account. This will understate your liabilities on the Balance Sheet and overstate your net income.
• Using One Vague "Payroll" Account: It may seem tempting to map all expense-related items to a single "Payroll Expenses" account, but this hinders your ability to analyze costs. Use separate expense accounts for Gross Wages, Employer Payroll Taxes, and company benefit contributions. This gives you much clearer insight on your Profit & Loss statement.
• Confusing Employee vs. Employer Accounts: ADP lists employee and employer portions of taxes separately (e.g., "Employee FICA" vs. "Employer FICA"). The employee portion is a liability (you collected it and owe it), while the employer portion is an expense to the company. Be sure to map them to the correct account types.
• Forgetting Clearing Accounts: Look for an ADP item named "Net Pay," "Direct Deposit," or "Cash Requirement." This line item represents the total cash leaving your bank for payroll. It should be mapped directly to the checking account from which you fund your payroll. If you make this mistake, your bank reconciliation will not be complete because the cash debit will not be accounted for in your books.

Finalizing and Managing the Connection

Once you are confident in your account mapping, save your configuration. The connection is now active. The next time you approve and run a payroll cycle in ADP, the system will automatically generate the journal entry and push it to QuickBooks Online, typically within a few hours. There is no manual "send" button you need to push; it happens automatically in the background going forward.

It is vital, however, to check your work after the very first automatic sync of information. Log in to QuickBooks Online, find that first journal entry (you can find it easily by searching recent transactions or running a Journal report), and review every single line. Check if the debits and credits correctly correspond to your mapping. Compare the totals to your payroll summary report from ADP to ensure they match perfectly without errors.

If you find a mistake—for instance, one account incorrectly mapped—you can simply delete the journal entry in QuickBooks, go back into the General Ledger configuration settings in ADP, correct the mapping, and request ADP to re-sync that period’s report to QuickBooks Online. This will create a new, corrected journal entry so you can adjust the mistake before it causes future problems in your books.
