Understanding Financial Transactions and Adjusting Entries

In this post, we’re going to explore accounting adjustments. These accounting adjustments affect four main account types:
- Prepaid expenses: These are expenses paid in advance, such as prepaid rent or insurance.
- Unearned revenues: This is cash received for goods or services that have not yet been delivered or performed. It’s a liability until the work is done.
- Accrued expenses: These are expenses that have been incurred but not yet paid or recorded, such as wages or interest.
- Accrued revenues: This is revenue that has been earned but for which cash has not yet been received.
Now, let’s see how these concepts apply to our example.
Part 1: Initial Transactions (March)
Imagine a small company, “Sunny Solar,” that sells and installs solar panels. Here are some of the transactions that might happen in March:
- Transaction a: Prepaid Insurance Sunny Solar pays $24,000 for a one-year insurance policy in advance. This is an asset for the company.
- Balance Sheet:
- Cash Asset: -$24,000
- Prepaid Insurance (Noncash Asset): +$24,000
- Balance Sheet:
- Transaction b: Customer Prepayment A customer pays Sunny Solar $5,000 in advance for a solar panel installation that will happen next month.
- Balance Sheet:
- Cash Asset: +$5,000
- Unearned Revenue (Liability): +$5,000
- Balance Sheet:
- Transaction c: Purchase on Credit Sunny Solar receives a bill for $2,000 for utility expenses, but they haven’t paid it yet.
- Balance Sheet:
- Utilities Payable (Liability): +$2,000
- Income Statement:
- Expenses: +$2,000
- Net Income: -$2,000
- Balance Sheet:
- Transaction d: Revenue on Account Sunny Solar completes a project for a client, billing them $15,000. The client has not paid yet.
- Balance Sheet:
- Accounts Receivable (Noncash Asset): +$15,000
- Income Statement:
- Revenue: +$15,000
- Net Income: +$15,000
- Balance Sheet:

Part 2: Adjusting Entries (End of March)
At the end of March, Sunny Solar needs to “adjust” some accounts to accurately reflect what happened during the month.
- Adjusting Entry A: Using Up Insurance One month of the prepaid insurance has now expired. Sunny Solar needs to record this as an expense.
- Balance Sheet:
- Prepaid Insurance (Noncash Asset): -$2,000 ($24,000 / 12 months)
- Retained Earnings (Capital): -$2,000
- Income Statement:
- Expenses: +$2,000
- Net Income: -$2,000
- Balance Sheet:
- Adjusting Entry B: Earning Revenue Sunny Solar completes the installation for the customer who paid in advance. Now they have “earned” the revenue.
- Balance Sheet:
- Unearned Revenue (Liability): -$5,000
- Retained Earnings (Capital): +$5,000
- Income Statement:
- Revenue: +$5,000
- Net Income: +$5,000
- Balance Sheet:
- Adjusting Entry C: Paying the Bill Sunny Solar pays the $2,000 utility bill they received earlier in the month.
- Balance Sheet:
- Cash Asset: -$2,000
- Utilities Payable (Liability): -$2,000
- Balance Sheet:
- Adjusting Entry D: Collecting Cash The client who was billed earlier for $15,000 now pays Sunny Solar.
- Balance Sheet:
- Cash Asset: +$15,000
- Accounts Receivable (Noncash Asset): -$15,000
- Balance Sheet:

By recording both initial transactions and these crucial adjusting entries, Sunny Solar can generate accurate financial statements that show a true picture of the company’s financial health.
