What Is an Accounts Payable Process?

Processing your accounts payable is a vital part of running a business. Here's what you need to know about setting up a timely and accurate accounts payable process.

When you’re running a business, an efficient accounts payable (AP) process is a must. It ensures that vendors and suppliers are paid on time and reduces waste by eliminating late fees or duplicate payments.

This article will explain how accounts payable works and how it differs from accounts receivable. We’ll also show you how to set up your own AP process.

What is accounts payable?

The accounts payable department manages the company’s payments for goods or services purchased from a vendor or supplier. You can track these liabilities on a balance sheet to monitor outstanding payments and ensure there are no overdue balances.

Your AP department oversees all outgoing payments and is usually the first point of contact for suppliers. Payment due dates can vary, so check individual invoices to ensure you’re aware of payment dates. If payments aren’t made on time, your company could get hit with late fees.

An accounts payable term you may hear frequently is “days payable outstanding” (DPO). This financial ratio measures the average number of days it takes a company to pay its vendors or suppliers. The longer it takes you to pay your suppliers, the higher your DPO.

Did You Know?

Accounts payable are considered a liability, since they represent money your business owes. This differs from accounts receivable, which are typically considered a business asset.

Accounts payable vs. accounts receivable

It’s easy to confuse accounts payable with accounts receivable, which involves collecting your unpaid invoices. While there are some overlaps, accounts payable and accounts receivable aren’t the same. 

Accounts payable deals with the money your business owes to its vendors and suppliers for goods and services purchased. In comparison, accounts receivable are the money owed to your company, usually by its customers. And while accounts payable are considered a liability, accounts receivable are considered an existing asset. 

Both accounts payable and accounts receivable are crucial aspects of the accounting process and work together to ensure your business functions smoothly. Both should be recorded to ensure accuracy and to track when outgoing and incoming payments are due. Without bringing in a profit, your company will be unable to meet its financial obligations.

Bottom Line

Accounts payable deals with the money your business owes, while accounts receivable is the money owed to your business.

Examples of accounts payable

Here are a few examples of accounts payable:

  • Equipment
  • Leasing
  • Subcontracting services
  • Raw materials
  • Traveling
  • Supplies
Did You Know?

There are two types of payables: trade payables and expense payables. Trade payables represent the purchase of physical goods, while expense payables refer to the purchase of expensed services, such as travel or supplies.

How to set up an accounts payable process

It’s important to record any purchases to your AP department as soon as they’re made. Once you pay the accounts, the balances will no longer show up in accounts payable.

Let’s look at a step-by-step guide for setting up an accounts payable process.

1. Create a chart of accounts.

Before you do anything else, you must create a chart of accounts to track your transactions. You can easily make one in Excel or a similar program.

A chart of accounts should include the following information:

  • Vendor names
  • Account and invoice numbers
  • Invoice date
  • Expense type
  • Payment deadline and status

2. Set up your vendors.

Next, create a spreadsheet with a list of your vendors. Here, you can detail exactly how each vendor is paid and when payment is due.

Maintaining a solid relationship with vendors will help your business in the long run. It will also ensure no hiccups arise when you’re buying their goods or services.

Make sure you enter the correct payment terms. Some vendors will offer a discount if the invoice is paid in full before a specific date. This is referred to as Net D. The terms will change depending on your agreement with the vendor.

For example, a 2% net 30 would provide a company with a 2% discount if the invoice is paid within 30 days. If your vendors don’t offer this currently, check with them and see if it’s an option. It’s an incentive to both the company and vendor to ensure smooth, on-time payments.

3. Receive invoices from suppliers.

Once you receive an invoice, review the bill to ensure there are no errors. Enter the invoice information after you confirm that all goods have been accounted for. The only exception would be if a vendor provided a service instead of a product.

Match the invoice to the purchase order to double-check that everything is correct. Once the invoice is paid, you may not be able to turn around and make any corrections to the order.

4. Process payments for outstanding invoices.

Check your AP at least once a week to ensure there are no unpaid invoices. You want to stay on top of payments to avoid penalties, such as interest and late fees, on unpaid invoices. There are many ways to pay your invoices, so it’s always best to see which method a specific vendor prefers.

Accounting software can help avoid any oversights in making payments. You can also set up payment alerts to ensure there are no outstanding invoices. Any extra step you can take to pay on time is highly recommended.

How accounting software can help manage the accounts payables process

There are many advantages to using accounting software for your accounts payables process. Online accounting software makes it easy to pay invoices electronically and avoid any past-due penalties.

Plus, having everything in one place makes it easier to track and manage your accounts. Handling everything manually leaves way too much room for human error.

By using accounting software, you can automate your accounts payable process to avoid any late payments. You can also link bank and credit card accounts so you won’t have to input that information manually. Additionally, accounting software provides a virtual paper trail in case there are any discrepancies. Overall, the appropriate software will save you time and energy.

There are many popular accounting software programs to choose from. Here’s a look at three of the top accounting software programs you’ll encounter as you begin your search.
