Revenue
Income & Revenue
The total money your business brings in from sales before any costs are subtracted.
If you sell $3,200 worth of goods at a weekend market, your revenue for that event is $3,200 — regardless of what it cost you to make or sell those items.
Gross Profit
Income & Revenue
Revenue minus the direct cost of making or purchasing what you sold (COGS). What's left before overhead and other operating expenses.
You made $3,200 in sales and your materials cost $900. Your gross profit is $2,300. This tells you if your pricing covers your production costs.
Net Profit
Income & Revenue
What's left after subtracting ALL expenses — including materials, overhead, fees, and taxes — from revenue. Your actual take-home.
After materials, booth fees, packaging, mileage, and taxes, that $3,200 market day might leave you with $900. That's your net profit — the number that actually matters.
Profit
Income & Revenue
The general term for money remaining after expenses. Can refer to gross or net depending on context — always clarify which one you mean.
When someone asks "is your business profitable?" they usually mean net profit. A business can have high revenue but zero profit if expenses are too high.
Profit Margin
Income & Revenue
Net profit expressed as a percentage of revenue. Shows how much of every dollar in sales you actually keep.
If your revenue is $3,200 and net profit is $900, your profit margin is 28%. A 30%+ margin is generally healthy for a market vendor business.
Markup
Income & Revenue
The percentage added above your cost to set a selling price. Different from margin — markup is calculated from cost, margin from price.
If a candle costs $4 to make and you sell it for $16, your markup is 300%. Many vendors underprice because they calculate markup on materials only and forget their labor.
Return on Investment (ROI)
Income & Revenue
The profit earned relative to what you invested, expressed as a percentage. Helps evaluate whether a purchase, event, or effort was worth it.
You spend $200 on a craft fair booth and make $800 in revenue with $300 in costs, netting $500. Your ROI is 150%. Use this to compare which events or investments perform best.
Expenses
Costs & Expenses
Everything your business spends money on to operate — materials, fees, supplies, subscriptions, mileage, and more.
Tracking every expense — even a $4 shipping label — is what separates vendors who know their real profit from those who guess.
Cost of Goods Sold (COGS)
Costs & Expenses
The direct costs tied to producing or purchasing the items you sell — materials, supplies, packaging, and production labor.
For a baker: flour, sugar, boxes, and the time spent baking are COGS. Your booth fee and Instagram ads are not — those are operating expenses.
Overhead
Costs & Expenses
Fixed or recurring business expenses that don't change based on how much you sell — rent, subscriptions, insurance, equipment.
Even on a slow month when you sell nothing, overhead still costs you money. Knowing your monthly overhead tells you the minimum revenue you need just to break even.
Operating Costs
Costs & Expenses
All costs required to run the business day-to-day — includes both COGS and overhead. Everything it takes to keep the doors open (or the booth set up).
Booth fees, mileage, materials, packaging, card reader fees, and your time are all operating costs. Knowing your total operating costs is essential for accurate pricing.
Startup Costs
Costs & Expenses
One-time expenses incurred to launch a business before regular operations begin — equipment, branding, initial inventory, permits, and setup.
Most vendors underestimate startup costs by 2–3x. A thorough startup cost plan prevents underfunding and helps you price accurately from day one.
Depreciation
Costs & Expenses
The gradual reduction in value of a business asset over time. Used to spread the cost of equipment across its useful life for tax and accounting purposes.
You buy a $1,200 tent for your booth. Rather than expensing it all at once, you might depreciate it over 5 years — $240/year. This affects your taxable income and true cost calculations.
Burn Rate
Costs & Expenses
How fast you're spending money — typically measured monthly. Critical during slow seasons when revenue dips but costs continue.
If your monthly expenses are $800 and you have $2,400 in the business account, your burn rate gives you 3 months of runway. Know this number before slow season hits.
Inventory
Costs & Expenses
The physical goods you have on hand to sell, or the raw materials used to make them. An asset on your books until sold.
Unsold inventory is money sitting on a shelf. Tracking your inventory helps you avoid overproducing, identify best sellers, and reduce wasted materials.
Self-Employment Tax
Taxes
The 15.3% tax (Social Security + Medicare) paid by self-employed individuals on net business income. Paid in addition to regular income tax.
As a sole proprietor or single-member LLC, you pay both the employer and employee share of this tax. Set aside 25–30% of net profit to cover this and income tax.
Quarterly Taxes
Taxes
Estimated tax payments made four times per year to the IRS (and often your state) when no employer is withholding taxes for you.
Due approximately April, June, September, and January. Missing these can result in penalties. If you expect to owe $1,000+ in taxes for the year, you likely need to pay quarterly.
Tax Deduction
Taxes
A legitimate business expense that reduces your taxable income. More deductions = lower tax bill.
Booth fees, mileage, materials, packaging, phone (partial), business software, and even a portion of your home workspace may all be deductible. Document everything with receipts.
Sales Tax
Taxes
A state-mandated tax collected from customers at the point of sale and remitted to the state. Rates and rules vary by state and product type.
Sales tax is not your income — it's collected on behalf of the state. Failing to collect or remit it correctly can result in penalties. Check your state's requirements and whether your products are taxable.
Audit Trail
Taxes
A chronological record of all financial transactions — receipts, invoices, bank statements — that can verify your income and expenses if questioned by the IRS.
Keep receipts for every business purchase, even small ones. An audit trail also helps you catch errors in your bookkeeping before they become bigger problems.
Financial Statement
Financial Statements
A formal record of financial activity. The three primary statements are the Profit & Loss, the Balance Sheet, and the Cash Flow Statement.
Even as a small vendor, running a monthly P&L tells you if your business is actually working — or if you're busy but broke.
Profit & Loss Statement (P&L)
Financial Statements
A report showing revenue, costs, and net profit over a specific time period. Also called an income statement.
Run a P&L monthly. It answers: "Did I actually make money this month?" — accounting for all costs, not just what hit your bank account.
Balance Sheet
Financial Statements
A snapshot of what your business owns (assets), what it owes (liabilities), and what's left for the owner (equity) at a given point in time.
Less critical for early-stage market vendors, but important as you grow — especially if you take on debt, have significant inventory, or seek financing.
Assets
Financial Statements
Everything your business owns that has value — cash, inventory, equipment, and accounts receivable.
Your booth tent, display fixtures, unsold inventory, and business bank balance are all assets. Knowing your total assets helps you understand the real value of your business.
Liabilities
Financial Statements
Everything your business owes — loans, outstanding bills, credit card balances, or taxes owed.
If you put $1,500 on a card to buy inventory and haven't paid it off, that's a liability. Liabilities reduce the true value of your business.
Owner's Equity
Financial Statements
The owner's financial stake in the business. Assets minus liabilities. What you'd be left with if you sold everything and paid off all debts.
As your business grows and becomes more profitable, owner's equity increases. It represents the true financial value you've built.
Cash Flow
Operations
The movement of money into and out of your business. Positive cash flow means more is coming in than going out. Negative cash flow means the opposite.
You can be profitable on paper but have no cash if you've spent on inventory before selling it. Cash flow is why profitable businesses sometimes can't pay their bills.
Bookkeeping
Operations
The ongoing process of recording all financial transactions — income and expenses — in an organized system.
Even a simple spreadsheet updated weekly counts as bookkeeping. Consistent bookkeeping makes tax season faster, cheaper, and far less stressful.
Reconciliation
Operations
The process of matching your internal records to your bank statements to ensure everything aligns and catch errors or missing transactions.
Do this monthly. Compare every transaction in your accounting system to your bank statement. Discrepancies catch fraud, errors, and missing deductions.
Invoice
Operations
A document sent to a customer requesting payment for goods or services delivered. Creates a formal record of what's owed.
If you do wholesale orders, custom work, or B2B sales, invoices protect you legally and create a paper trail for your accounting records.
Accounts Receivable
Operations
Money owed to your business by customers for goods or services already delivered but not yet paid for.
If you invoice a boutique for a wholesale order and they haven't paid yet, that amount is accounts receivable — it's revenue you've earned but haven't collected.
Accounts Payable
Operations
Money your business owes to suppliers or vendors for goods or services already received but not yet paid.
If a supplier shipped you materials on net-30 terms and you haven't paid yet, that's accounts payable. Staying on top of this prevents late fees and protects supplier relationships.
Purchase Order
Operations
A formal document sent to a supplier to authorize a purchase — specifying items, quantities, and agreed price before payment is made.
As you scale, purchase orders protect you from billing disputes with suppliers and create a clear record of what was ordered and at what price.
Payroll
Operations
The process of paying employees or contractors, including calculating wages, withholding taxes, and filing payroll tax returns.
Most early vendors are solo. But once you hire help — even part-time — payroll rules apply. Misclassifying employees as contractors is a common and costly mistake.
Working Capital
Operations
Current assets minus current liabilities. The liquid funds available to run day-to-day operations.
If you have $2,000 in the business account and $600 in outstanding bills, your working capital is $1,400. This is the cushion that keeps you operating between markets.
Budget
Planning
A plan for how you expect to earn and spend money over a set time period. Your financial roadmap.
A simple monthly budget — projected revenue vs. expected expenses — prevents overspending and helps you spot cash flow problems before they happen.
Break-Even Point
Planning
The point where total revenue equals total costs — no profit, no loss. The minimum you need to earn to cover all expenses.
If your monthly costs are $1,200, you need to generate at least $1,200 in revenue just to break even. Anything above that is profit. Know this number before every market season.
Forecasting
Planning
Estimating future financial performance based on historical data, trends, and business conditions.
Looking at last year's sales by month helps you forecast when to ramp up production, when to save cash reserves, and when to apply for more events.
Financial Projection
Planning
A forward-looking estimate of revenue, expenses, and profit — used to plan for growth, evaluate investments, or apply for financing.
A 12-month financial projection shows whether your planned market schedule and pricing can realistically hit your income goals before the season starts.
KPI (Key Performance Indicator)
Planning
A measurable value that tracks progress toward a specific business goal. Not all numbers are KPIs — only the ones tied to outcomes that matter.
For market vendors: revenue per event, sell-through rate, average transaction value, and repeat customer rate are high-value KPIs. Track 3–5 consistently rather than everything at once.
