Accounts Payable in QuickBooks: How to Manage It Properly

Accounts Payable is the record of what you owe your vendors. QuickBooks creates the A/P account automatically the first time you enter a bill, then tracks every bill and payment against it.

At QuickFix Bookkeeping, the rule that keeps A/P clean: if you entered a bill, pay it with Pay Bills, never with Write Check. Bypassing the bill creates a duplicate expense and leaves the original bill sitting open forever.

The Two A/P Workflows

Standard

Enter Bill, then Pay Bills. Use this when you receive a vendor invoice and pay it later on terms. This is the correct default for most businesses.

With Purchase Orders

Purchase Order, receive inventory, then enter the bill against it. Use this if you track goods on order. Available in Desktop Pro, Premier, and Enterprise.

Managing Accounts Payable, Step by Step

METHOD 1Enter a BillCreates the A/P liability
1

QuickBooks Online: select + New, then Bill. Enter the vendor, bill date, due date, and the expense account or item lines. Save and close.

2

QuickBooks Desktop: go to Vendors, then Enter Bills, and fill in the same details. The first bill you enter creates the Accounts Payable account on your Chart of Accounts automatically.

3

Set the bill date correctly. On accrual basis the expense is recorded on the bill date, not the payment date, so a wrong date shifts the expense into the wrong period.

METHOD 2Pay the Bill CorrectlyNever use Write Check
1

QuickBooks Online: select + New, then Pay bills. Tick the bills to settle, choose the bank account, confirm the amounts, and save.

2

QuickBooks Desktop: go to Vendors, then Pay Bills. Select the bills, apply any vendor credits via Set Credits, then Pay Selected Bills.

3

If you already paid by check by mistake, open the check, change its expense account to Accounts Payable, set the vendor in the name field, save, then go to Pay Bills and apply that credit to the open bill. This links them and clears the duplicate.

METHOD 3Run the A/P Aging ReportYour cash flow view
1

Go to Reports and run Accounts Payable Aging Summary. It groups unpaid bills by how overdue they are, so you can see what is due now versus in 60 days.

2

Run it weekly. Pair it with the Unpaid Bills Detail report to catch bills entered twice or bills that were paid but never marked as such.

Before You Close the Year

Clean A/P is a prerequisite for accurate year-end books. Run the aging report, clear duplicate bills, apply outstanding vendor credits, and confirm every 1099 contractor is paid from a mapped account. See our year-end checklist and 1099 account mapping guide.
