What is Accounts Receivable?

Why It Matters

Accounts receivable is where the rubber meets the road between profit and cash. You can be making money on paper while running out of cash in your bank account, and that gap is almost always accounts receivable.

For business owners, the danger is real. You invoice a customer for $50,000 of work. Your profit and loss statement shows $50,000 in revenue. But if that customer doesn't pay for 90 days and you're on a 30-day payroll cycle, you have a cash crisis. You've spent money to deliver the work, but the cash hasn't come in yet. Many businesses have failed not because they weren't profitable, but because they ran out of cash waiting for invoices to be paid.

For accountants and bookkeepers, accounts receivable directly impacts three things: (1) the balance sheet - AR is listed as a current asset and affects your working capital and liquidity ratios; (2) cash flow forecasting - you must distinguish between revenue recognized and cash collected; and (3) bad debt provision - the longer an invoice sits unpaid, the more likely it never gets paid, and you need reserves for that risk.

The accounts receivable aging report - a breakdown of how many invoices are 0-30 days, 30-60 days, 60-90 days, and over 90 days old - is the single most important management report for cash flow. If you have $200,000 in AR but $150,000 is over 90 days old, you don't actually have $200,000 of cash coming in. That's a collection problem that needs immediate attention.

How It Works

Accounts receivable works across a simple timeline: you invoice, the customer owes you, time passes, you collect.

The process:

1. You deliver goods or services. On that delivery date, you issue an invoice. The invoice is dated and contains payment terms (Net 30, Net 60, payment on receipt, etc.).

2. Revenue is recognized. Under accruals accounting (the standard), you record the revenue immediately when you invoice - not when you get paid. Your P&L shows the revenue that day.

3. Accounts receivable is created. That unpaid invoice is now an asset on your balance sheet called accounts receivable. It sits there until paid.

4. Customer pays. When the payment arrives, accounts receivable decreases (the invoice is now paid) and cash increases. Your P&L revenue doesn't change - you already recognized it on the invoice date.

5. Cash flow timing. The gap between invoice date and payment date is where cash flow problems hide. This gap is what you track in your AR aging report.

Real example:

A freelance designer invoices a client for $8,000 on March 15 with Net 30 terms. On March 15, the $8,000 is recorded as revenue (P&L shows profit) and accounts receivable increases to $8,000. The designer's cash account hasn't changed. On April 14 (29 days later), the client pays. Now accounts receivable drops to $0 and cash increases by $8,000. The revenue was the same on both dates - it was recognized on March 15. But the cash took 30 days to arrive.

AR aging variation:

Most businesses don't have all customers paying on time. A more realistic example: a $50,000 invoice on day 1 splits across 0-30 days ($15,000 paid), 30-60 days ($20,000 still outstanding), and over 60 days ($15,000 severely overdue). Your aging report shows exactly this breakdown so you know how much cash is truly at risk.

Key Considerations

Common mistakes:

• Confusing revenue and cash. You can have $100,000 in revenue and $0 in cash if none of it's been collected. This is the number one reason profitable businesses go bankrupt.
• Not following up. Every day an invoice sits unpaid, the probability of collection drops. At 30 days it's still very likely. At 90 days, about 50% get paid. At 120 days, only about 10% ever pay. Follow up early.
• Ignoring AR aging. If 80% of your AR is over 60 days old, you have a pricing, delivery, or customer problem - or you're dealing with serial late payers. This needs fixing immediately, not ignoring.
• Not using payment terms. Vague payment terms like "pay when you can" guarantee slow payment. Explicit terms like Net 30 or 50% upfront clarify expectations and give you grounds to charge late fees.
• Writing off bad debts too late. If an invoice is over 120 days old and the customer is unresponsive, write it off or set a reserve. Carrying it at full value on your balance sheet is dishonest.

Best practices:

• Calculate your Days Sales Outstanding (DSO): divide total accounts receivable by daily revenue. This tells you how many days, on average, cash takes to arrive. Track it monthly; if DSO is growing, you have a problem.
• Set up automated payment reminders at 15 days and 30 days past due.
• Negotiate payment terms with large customers upfront - don't let them dictate terms after the fact.
• For high-value contracts, ask for a deposit (30-50%) upfront to reduce your AR risk.

How Aarvo Helps

Aarvo automatically calculates your accounts receivable balance and aging as invoices land in the system. The dashboard shows total AR, broken down by age bucket (0-30, 30-60, 60-90, 90+ days). You can see at a glance how much cash is outstanding and how long it's been outstanding.

The aging report flags invoices over 60 days so you can prioritize follow-ups. Aarvo also integrates with payment processors and bank feeds, so when a customer pays, the invoice is automatically marked paid and your AR balance updates in real-time. This means you always know your true cash position - revenue recognized versus cash collected.
