Master your numbers at the Accountlet Academy

Bookkeeping isn't a once-a-year scramble — it's a short, repeatable routine you run every month. Accountants call finishing a month's books the monthly close: the point where every transaction is recorded, every account is reconciled, and your reports can be trusted. Closing the books on a schedule means mistakes get caught while they're small and easy to fix, instead of compounding into a year-end mess. Here's the four-week rhythm that keeps a set of books clean.

Week 1 — Review & reconcile

Reconciling means matching your books against an outside record — your bank or credit-card statement — until the ending balances agree. If they don't match, something is missing, duplicated, or miscategorized, and reconciliation is how you find it before it reaches your reports.

• Reconcile every bank account — compare each statement to your books line by line and chase down any difference until it ties out.
• Reconcile every credit card — same process for each card, so both the spending and the payments are captured.
• Clear undeposited funds — confirm every payment you received was actually recorded and deposited, not left sitting in a holding account.
• Catch duplicates — bank feeds sometimes import the same transaction twice; remove the extras before they distort your numbers.

Week 2 — Receivables & payables

This is the money owed to you (receivables) and the money you owe others (payables). Staying on top of both protects your cash and keeps your profit picture honest.

• Send and follow up on invoices — bill promptly and chase overdue balances; the longer an invoice sits, the less likely it gets paid.
• Record all income — every sale, deposit, and payment, so the revenue on your books matches what actually hit your accounts.
• Pay bills on schedule — enter vendor bills and pay them on time to avoid late fees and keep vendor relationships healthy.
• Categorize as you go — assign each expense to the right account now, while you still remember what it was for.

Week 3 — Payroll & recurring obligations

If you have employees or contractors, this is where you record what they're paid and what you owe as a result. The bookkeeping job is accuracy and timing — getting the right amounts into the right period.

• Run payroll on schedule — record wages and withholdings so labor cost lands in the correct month.
• Record payroll liabilities — amounts withheld and owed sit as liabilities on your books until they're remitted; track them so nothing slips.
• Track contractor payments — keep running totals for vendors you'll need to report at year-end, so the numbers are ready when you need them.

Week 4 — Review & plan

• Generate your statements — profit & loss, balance sheet, and cash flow for the month (Lesson 06 shows how to read them).
• Compare to prior periods — set this month beside last month and the same month last year; the trend is where the story lives.
• Update your cash forecast — roll your projected cash position forward three months.
• Back up — keep copies of key documents and confirm your records are saved.

Cash flow is the timing of money moving in and out of your business — and it's different from profit in a way that catches owners off guard. You can show a healthy profit on your P&L and still not have the cash to make payroll. Here's why: say you invoice a customer $20,000 in March and book it as revenue, but they don't pay until May. March looks profitable, yet your bank account is empty until the money lands. Profit is earned; cash is collected. Books that stay current are what let you see that gap coming instead of getting blindsided by it.

Seven habits that keep you liquid

1. Forecast weekly. Project your cash position three to six months out and refresh it every week. A short, regularly-updated forecast warns you about a tight month while you still have room to act.

2. Speed up what's owed to you. Invoice the moment work is done, make it easy to pay with multiple methods, and follow up on a set schedule — say at 7, 14, and 30 days overdue. On large jobs, ask for a deposit up front so you're not financing the work out of your own pocket.

3. Time what you owe. If a bill is Net 30, there's no prize for paying on day 3 — pay on day 30 and keep the cash working until then. Negotiate longer terms with vendors where you can.

4. Build a reserve. Aim to hold three to six months of operating expenses in reserve. The simplest path there is to set aside a fixed percentage of every deposit before you spend a dollar of it.

5. Watch the right numbers. Your bank balance alone is misleading. Two bookkeeping metrics tell you more: days sales outstanding (DSO) — the average number of days customers take to pay you, where lower is better — and cash runway — how many months your current cash can cover your expenses.

6. Trim quiet costs. Reconciled books make forgotten subscriptions and creeping vendor charges visible. Review them monthly and cancel what you don't use.

7. Line up credit before you need it. A line of credit is far easier to secure when your books are clean and the business is stable than when you're already scrambling for cash.

Every report you run is only as good as the categories behind it. Categorizing — also called coding — means assigning each transaction to the right account in your chart of accounts. Do it consistently and your profit & loss tells a clear story; do it carelessly and the numbers turn to noise. This lesson is about classification only: where each transaction belongs in your books — clean categories in, clear reports out.

Your chart of accounts is the menu

The chart of accounts is the master list of every category your business uses — assets, liabilities, equity, income, and expenses. Good categorization starts with a chart that actually fits your business, plus one rule you never break: code the same kind of transaction to the same account every time. That consistency is what makes month-to-month and year-over-year comparisons mean anything.

Cost of goods sold vs. operating expenses

This is the distinction owners get wrong most often, and it directly changes your gross margin. Cost of goods sold (COGS) is what you spend to deliver the product or service you sell — materials, the labor that produces the work, merchant fees tied to a sale. Operating expenses are the costs of running the business whether or not you make a sale — rent, software, marketing, office supplies. Drop a cost in the wrong bucket and your gross margin (revenue minus COGS) is wrong, which quietly throws off every pricing decision you base on it.

Five classification traps to avoid

• Owner's money isn't an expense. When an owner takes money out, that's an owner's draw (equity), not a business expense. When an owner puts money in, that's a contribution, not income. Coding either as expense or revenue distorts your profit.
• Transfers aren't income or expense. Moving money between your own accounts — checking to savings, or drawing down a loan — is a transfer. Booking it as revenue inflates your sales; booking it as expense inflates your costs.
• Loan payments are split. A loan payment is part principal (which reduces a liability) and part interest (an expense). Coding the whole payment to one account misstates both your debt and your expenses.
• Big purchases may be assets. Equipment or a computer you'll use for years is generally recorded as a fixed asset on the balance sheet, not a one-month expense, and its cost is spread over time. Your bookkeeper or accountant sets the dollar threshold.
• A credit-card payment isn't an expense. The expenses are the individual charges on the card. Paying the balance just moves money from your bank to the card liability — recording the payment itself as an expense double-counts everything.

The hour you spend setting QuickBooks up properly saves you days of cleanup down the road. Most messy books trace straight back to a rushed setup — accounts connected in the wrong order, a chart of accounts left on default, or years of old history dumped in on day one. Follow this order and you'll start clean.

The seven setup steps, in order

• 1. Company information. Enter your legal name, address, business structure, and fiscal year first — these settings shape your reports and are a nuisance to change later.
• 2. Connect your accounts. Link your business bank, credit cards, and payment processors (Stripe, PayPal, Square) so transactions flow in automatically instead of being keyed by hand.
• 3. Build your chart of accounts. Don't accept the defaults blindly. Keep the categories that fit your business, add the ones you need, and hide the rest — a focused chart makes coding faster and reports cleaner.
• 4. Add customers. Import your customer list, set default payment terms, and create an invoice template so billing stays consistent.
• 5. Add vendors. Enter your regular vendors and flag the ones you'll report on at year-end, so contractor totals are ready when the deadline comes.
• 6. Add products & services. List what you sell with prices; turn on inventory tracking only if you actually hold stock — it lives on higher tiers and adds real complexity.
• 7. Enter opening balances. Record the starting balance for each account as of your start date and reconcile, so your books begin from a verified, accurate point.

Clean expense records make everything else in bookkeeping easier — faster reconciliations, accurate reports, and a clear answer to "what did we actually spend on this?" whenever a lender, a partner, or your bookkeeper asks. The goal is simple: capture every business expense with enough detail to know what it was and why.

The essentials

• Separate business and personal — completely. A dedicated business bank account, card, and payment processor is rule number one. Mixing personal and business spending is the single biggest source of bookkeeping cleanup there is.
• Capture receipts immediately. Photograph the receipt and note the business purpose on the spot — memories fade fast, and a receipt with no context is hard to use later.
• Categorize consistently. Use specific categories instead of a catch-all "miscellaneous," and code the same kind of charge the same way every time (Lesson 03 covers how).
• Document the context. For travel or client meals, jot down who, what, where, and the business reason — the detail that turns a charge into a record you can stand behind.
• Attach and retain. Attach the receipt image to the transaction in your software and keep your records organized, so any entry can be substantiated long after the fact.

Three statements tell you almost everything about your business's health. They come straight out of well-kept books, and each one answers a different question. Learn to read them together and you'll spot problems months before they ever reach your bank balance.

Profit & Loss — "Am I making money?"

The P&L (also called the income statement) shows revenue minus expenses over a span of time — a month, a quarter, a year. Read it top down: revenue, then cost of goods sold, which gives you gross profit; then operating expenses, which gives you net profit. Track your gross margin (gross profit ÷ revenue) and net margin (net profit ÷ revenue), and scan for any single expense category climbing faster than revenue — that's usually where margin quietly leaks away.

Balance Sheet — "What does my business own and owe?"

Where the P&L covers a stretch of time, the balance sheet is a snapshot on a single day. It lists assets (what you own), liabilities (what you owe), and equity (the owners' share) — and it always balances, because assets equal liabilities plus equity. Watch your current ratio (current assets ÷ current liabilities; comfortably above 1 means you can cover near-term bills), how old your receivables are getting, and whether debt is trending up or down.

Cash Flow Statement — "Where did the cash actually go?"

This statement bridges profit and cash by tracking money through three activities: operating (day-to-day business), investing (buying or selling assets), and financing (loans and owner money). Healthy businesses generate positive cash from operations. If you're profitable but cash keeps falling, this is the statement that points to the culprit — usually slow-paying customers or cash tied up in inventory.
