Accounts Receivable vs Accounts Payable

Quick answer

Accounts receivable (AR) is money your customers owe you — it's an asset. Accounts payable (AP) is money you owe your suppliers — it's a liability. AR increases when you invoice a customer; AP increases when you receive a bill. Good cash flow management means collecting AR fast and paying AP slowly.

Every business has both AR and AP. Understanding how each works — and how they affect your cash flow — is essential for avoiding a cash crunch even when business is booming.

What is accounts receivable?

Accounts receivable (AR) represents money your customers owe you for goods or services you've already delivered. It's created when you sell on credit — invoice now, get paid later. AR is listed as a current asset on your balance sheet because it's expected to convert to cash within 12 months.

How AR is created

You deliver a product or service and send an invoice. Before the invoice is paid, the amount sits in AR. When the customer pays, AR decreases and cash increases.

Why high AR is a problem

High AR means you've made sales but haven't collected the cash. You can be profitable on paper but unable to pay your own bills. This is the 'profitable but broke' problem many service businesses face.

How to manage AR

Send invoices immediately. Set clear payment terms (Net 30, Net 15). Follow up on late invoices. Offer early payment discounts (2/10 Net 30 = 2% off if paid within 10 days).

Key AR metric: Days Sales Outstanding (DSO)

DSO = (Accounts Receivable ÷ Annual Credit Sales) × 365

Lower DSO = faster collection. Example: $50,000 AR ÷ $600,000 annual credit sales × 365 = 30 days DSO. Target under 45 days for most B2B businesses; under 10 days for retail.

What is accounts payable?

Accounts payable (AP) represents money you owe your suppliers and vendors for goods or services they've already delivered to you. AP is a current liability on your balance sheet. When you pay an invoice, AP decreases and cash decreases by the same amount.

How AP is created

Your supplier delivers goods or services and sends you an invoice. Before you pay, the amount sits in AP. When you pay, AP decreases and cash decreases by the same amount.

Why managing AP matters

Paying too fast depletes cash unnecessarily. Paying too slow damages supplier relationships and can result in late fees or supply disruptions. The goal: pay within your terms but not before.

How to manage AP

Negotiate favorable payment terms with suppliers (Net 60 instead of Net 30 if possible). Pay on the due date — not early. Take early payment discounts only if the discount exceeds your cost of capital.

Key AP metric: Days Payable Outstanding (DPO)

DPO = (Accounts Payable ÷ Cost of Goods Sold) × 365

Higher DPO = more time holding cash. Example: $30,000 AP ÷ $365,000 COGS × 365 = 30 days DPO. Large retailers often achieve 60-90+ day DPO by negotiating extended terms with suppliers.

The cash conversion cycle: AR + AP together

Cash Conversion Cycle (CCC)

CCC = Days Inventory Outstanding (DIO) + DSO − DPO

CCC measures how many days cash is tied up in your operating cycle. A lower (or negative) CCC is better — it means you're collecting cash faster than you're spending it. Amazon and Walmart have negative CCCs because they collect from customers before paying suppliers.

To lower DSO

Invoice faster, follow up on late payments, offer early-pay discounts

To raise DPO

Negotiate longer payment terms, pay on due date (not early)

To lower DIO

Reduce inventory levels, improve forecasting, use just-in-time ordering

Frequently asked questions

What is the difference between accounts receivable and accounts payable?+

Accounts receivable (AR) is money your customers owe you for goods or services you've delivered but haven't been paid for yet — it's an asset on your balance sheet. Accounts payable (AP) is money you owe your suppliers or vendors for goods or services they've delivered to you — it's a liability. Simply: AR = money coming in. AP = money going out.

Is accounts receivable an asset or liability?+

Accounts receivable is a current asset. It represents money owed to your business and expected to be collected within one year. It appears on the asset side of your balance sheet. Once collected, it converts to cash. If it's uncollectable, you write it off as bad debt expense.

Is accounts payable an asset or liability?+

Accounts payable is a current liability. It represents money your business owes to suppliers and vendors that is due within one year (usually 30–90 days). It appears on the liabilities side of your balance sheet. When paid, it reduces both cash and AP simultaneously.

What is the accounts receivable turnover ratio?+

AR Turnover = Net Credit Sales ÷ Average Accounts Receivable. It measures how quickly your business collects payment from customers. A higher ratio is better — it means faster collection. For example, if you have $500,000 in annual credit sales and average AR of $50,000, your AR turnover is 10 (you collect each invoice about every 36 days).

What is Days Sales Outstanding (DSO)?+

DSO = (Accounts Receivable ÷ Net Credit Sales) × Number of Days. It measures the average number of days it takes to collect payment after a sale. Lower DSO is better. Example: $50,000 AR ÷ $500,000 annual sales × 365 = 36.5 days DSO. Industry averages vary: retail is 3-7 days, B2B services average 30-60 days.

What is Days Payable Outstanding (DPO)?+

DPO = (Accounts Payable ÷ Cost of Goods Sold) × Number of Days. It measures how long your business takes to pay suppliers. Higher DPO means you're holding onto cash longer — beneficial for cash flow as long as you're not damaging supplier relationships. A DPO of 45 days means you pay invoices about 45 days after receiving them.

How do AR and AP affect cash flow?+

High AR (customers pay slowly) = cash tied up in invoices = potential cash crunch despite strong sales. High AP (you pay slowly) = preserving cash by delaying payments = better short-term liquidity. The ideal: collect AR fast (low DSO), pay AP slowly (high DPO). This combination maximizes the cash in your account at any time.

What is the cash conversion cycle?+

Cash Conversion Cycle (CCC) = Days Inventory Outstanding + Days Sales Outstanding − Days Payable Outstanding. It measures how many days it takes to convert inventory or services into cash. A negative CCC (like Amazon's) means you collect from customers before paying suppliers. Lower CCC = better cash efficiency.
