Accounts Receivable: The Complete Guide for Bookkeepers

Updated March 2026 · 22 min read · 40,500 monthly searches

What Is Accounts Receivable?

Accounts receivable (AR) represents money that customers owe a business for goods or services delivered but not yet paid for. It's recorded as a current asset on the balance sheet because it's expected to be converted to cash within the normal operating cycle (usually 30-90 days).

Simple Example

A plumber completes a $5,000 bathroom renovation for a client and sends an invoice with Net 30 payment terms. Until the client pays, that $5,000 sits in accounts receivable. It's revenue earned but cash not yet collected.

Accounts Receivable vs. Accounts Payable

The Accounts Receivable Process (Step by Step)

Step 1: Establish Credit Terms

Before extending credit, businesses need clear payment terms. Common terms include:

• Net 30: Payment due within 30 days (most common)
• Net 15: Payment due within 15 days (for smaller amounts or new customers)
• 2/10 Net 30: 2% discount if paid within 10 days, full amount due in 30
• Due on receipt: Payment expected immediately (for retail/service businesses)

Step 2: Issue Invoices

Every invoice should include: customer name and contact info, invoice number, date issued, payment due date, line items with descriptions and amounts, payment instructions, and late payment terms.

Step 3: Record the Receivable

Using double-entry bookkeeping:

Step 4: Track and Follow Up

Monitor payment status, send reminders before due dates, and follow up on overdue invoices. This is where most small businesses fail — and where bookkeepers add massive value.

Step 5: Record Payment

Step 6: Handle Bad Debts

When a customer can't or won't pay, you need to write off the bad debt:

AR Aging Reports: Your Most Powerful Tool

An accounts receivable aging report categorizes outstanding invoices by how long they've been unpaid. It's the single most important report for managing cash flow.

Industry benchmark: A healthy business should have less than 10% of total AR over 60 days. If more than 20% is over 60 days, there's a serious collections problem that needs immediate attention.

Key AR Metrics Every Bookkeeper Should Track

1. Days Sales Outstanding (DSO)

Formula: (Accounts Receivable ÷ Total Credit Sales) × Number of Days

DSO tells you the average number of days it takes to collect payment. Lower is better.

• Excellent: Under 30 days
• Average: 30-45 days
• Concerning: Over 45 days

2. AR Turnover Ratio

Formula: Net Credit Sales ÷ Average Accounts Receivable

Shows how many times per year a company collects its average AR balance. Higher is better — it means faster collections.

3. Collection Effectiveness Index (CEI)

Formula: (Beginning AR + Credit Sales - Ending Total AR) ÷ (Beginning AR + Credit Sales - Ending Current AR) × 100

The gold standard metric for measuring collection performance. A CEI above 80% is good; above 90% is excellent.

4. Bad Debt Ratio

Formula: Bad Debt Write-offs ÷ Total Credit Sales × 100

Track this monthly. If it's consistently above 2%, there may be issues with the credit approval process.

Collection Strategies That Actually Work

Prevention Is Better Than Collection

• Credit checks before extending Net 30+ terms to new customers
• Clear payment terms on every contract and invoice
• Deposits or progress payments for large projects
• Automated invoicing — invoices sent the day work is completed, not next week
• Multiple payment options — credit card, ACH, wire transfer, check

The Collection Sequence

1. Day 25: Friendly reminder email ("Invoice #1234 is due in 5 days")
2. Day 31: Polite follow-up ("Just a friendly reminder that payment is now past due")
3. Day 45: Phone call from bookkeeper or AR specialist
4. Day 60: Formal letter, pause new work for this customer
5. Day 75: Final notice, offer payment plan
6. Day 90: Send to collections or write off

AR Management as an Advisory Service

This is where the real money is for bookkeepers. Most small business owners have no idea how much their AR problems are costing them. You can turn basic AR management into a premium advisory service:

What $40/Hour AR Work Looks Like:

• Recording invoices
• Matching payments
• Running aging reports
• Basic follow-up emails

What $200/Hour AR Advisory Looks Like:

• Cash flow impact analysis: "Your DSO increased from 32 to 47 days this quarter. Here's what that's costing you in cash flow and here's how we fix it."
• Credit policy design: Creating tiered credit terms based on customer payment history and size
• Collection process optimization: Building automated sequences that reduce DSO by 15-20 days
• Customer profitability analysis: "Client X pays 45 days late consistently. Factor in the cost of capital, and they're actually your least profitable customer."
• Cash flow forecasting using AR aging data to predict incoming cash

AR Software & Automation

Modern accounting software handles much of the AR grunt work. Here's what to use:

Common AR Mistakes to Avoid

1. Invoicing late: Every day you delay sending an invoice is a day added to your DSO
2. Inconsistent follow-up: Customers learn quickly which vendors enforce payment terms
3. No credit policy: Extending Net 30 to everyone is asking for bad debt
4. Ignoring aging reports: Running the report isn't enough — you need to act on it
5. Not offering early payment discounts: 2/10 Net 30 can dramatically reduce DSO

Frequently Asked Questions

Is accounts receivable an asset or liability?

Accounts receivable is a current asset. It represents money owed to the business that will be converted to cash, typically within 30-90 days.

What's a good accounts receivable turnover ratio?

It varies by industry, but generally 7-10 times per year (meaning you collect your average AR balance every 37-52 days). Higher is better.

How do bookkeepers handle accounts receivable?

Bookkeepers record invoices, match incoming payments, run aging reports, send payment reminders, and flag overdue accounts. Advanced bookkeepers also analyze AR trends and advise on credit policies.

What causes high accounts receivable?

Common causes include: loose credit terms, poor invoicing practices, lack of follow-up on overdue accounts, customer financial difficulties, and unclear payment instructions on invoices.
