Master Single-Entry Bookkeeping: A Simple System for Solo Entrepreneurs
If you're a new solo entrepreneur, the term "bookkeeping" might sound intimidating. You might picture complex ledgers and confusing accounting rules. But it doesn't have to be that way. For many small businesses, a single-entry bookkeeping system is a simple, practical, and powerful way to stay organized and ready for tax time.
This system is based on your business's income statement (your profit and loss) and focuses on one thing: tracking the flow of cash in and out of your business. It's the perfect starting point.
Let's walk through how to set up your own single-entry system using a real-world example from the IRS documentation for an auto body shop owner named Henry.
What is Single-Entry Bookkeeping?
A single-entry system records the flow of income and expenses through a few key documents:
- A daily summary of your cash receipts.
- Monthly summaries of your cash receipts and your cash disbursements (expenses).
The foundation of this entire system is your business checkbook. It serves as the main source for all the entries you'll make in your books.
Step 1: Track Your Daily Cash Receipts
The first step is to account for the cash you receive each day. A daily summary helps you track cash sales and ensures your cash register total is accurate.
How it works:
At the end of each business day, you'll total up all the cash you have on hand. From this total, you subtract the starting amount you keep in the register for making change (this might also include your petty cash fund). The result is your total cash receipts for the day.
Example: Daily Summary of Cash Receipts
Here’s a look at Henry's summary for January 3rd:
| Item | Amount |
|---|---|
| Cash Sales | $263.60 |
| Sales Tax | $4.20 |
| Total Cash Receipts | $267.80 |
Henry then takes this total of $267.80 and carries it over to his monthly summary.
Step 2: Create Your Monthly Summaries
Next, you'll compile your daily numbers into a monthly summary. This gives you a clear picture of your income activity for the entire month. You will need one summary for receipts and another for expenses.
Monthly Summary of Cash Receipts
This document tracks your daily income, separates out any sales tax you collected (since that money belongs to the state, not you), and matches the totals to your bank deposits.
Example: A Snippet of a Monthly Cash Receipt Summary
| Day | Net Sales | Sales Tax | Daily Receipts | Deposit |
|---|---|---|---|---|
| 3 | $263.60 | $4.20 | $267.80 | |
| 4 | $212.00 | $3.39 | $215.39 | |
| 5 | $194.40 | $3.10 | $197.50 | $680.69 |
| ... | ... | ... | ... | ... |
| Total | $4,865.05 | $77.51 | $4,942.56 | $4,942.56 |
At the end of the year, the monthly totals are added up in an Annual Summary, which provides the final income figures for your tax return (like Schedule C).
Check Disbursements Journal (Monthly Expense Summary)
This is where you record all the money you spend from your business checking account.
How to Set It Up:
Create a journal with columns for the key details of each check you write: the date, who it was paid to, the check number, and the amount. Then, create separate columns for your most frequent expense categories, like "Materials," "Rent," or "Utilities." For everything else, you can use a "General Accounts" column.
Example: A Snippet of a Check Disbursements Journal
| Date | Paid To | Chk # | Amount | Materials | Rent | Truck/Auto | General Accounts |
|---|---|---|---|---|---|---|---|
| Jan 3 | Dale Advertising | 74 | $85.00 | Advertising $85.00 | |||
| Jan 4 | Auto Parts, Inc. | 76 | $203.00 | $203.00 | |||
| Jan 6 | Joe's Service St. | 80 | $74.50 | $45.00 | |||
| Jan 25 | Enterprise Prop. | 95 | $300.00 | $300.00 | |||
| ... | ... | ... | ... | ... | ... | ... | ... |
| Total | $3,488.67 | $1,083.50 | $300.00 | $45.00 | $305.00 |
Just like with receipts, you'll carry these monthly expense totals over to your Annual Summary to prepare your tax return.
When to Graduate to Double-Entry Bookkeeping
A single-entry system is fantastic for its simplicity. However, as your business grows, you may need a more robust system. You should consider graduating to a double-entry system when you need to track more than just cash flow.
A double-entry system is self-balancing and tracks:
- Assets: Property your business owns (like equipment or buildings).
- Liabilities: Debts your business owes (like loans).
- Equity: Your net worth in the business.
This system gives you a more complete financial picture, including a balance sheet, which shows your assets, liabilities, and equity on a given date. A double-entry system is better suited for businesses that are incorporated, have significant inventory, or need detailed financial statements for banks or investors.
For now, mastering a simple single-entry system will put you on solid footing, giving you the clarity and organization you need to manage your finances and succeed as a solo entrepreneur.
