Net income is the bottom of the income statement — the "profit" in plain English. Everything above it is part of getting there: revenue, cost of goods, operating expenses, interest, taxes. Net income is what is left for owners and shareholders after all of it is paid.
The formula step by step
Net Income = Total Revenue − Total Expenses
Expanded into the full income statement walk:
- Gross Revenue
- − Refunds, returns, discounts = Net Revenue
- − Cost of goods sold (COGS) = Gross Profit
- − Operating expenses (marketing, salaries, rent, software) = Operating Income
- − Interest and other non-operating expenses = Pre-tax Income
- − Taxes = Net Income
What net income tells a subscription merchant
For subscription businesses on Shopify, net income is the truth test of the business model. You can have growing gross revenue, healthy ARR, and a celebrated brand, but if net income is consistently negative the unit economics are not working. The question to interrogate is which line item is consuming the margin — cost of goods, customer acquisition cost, or fulfillment.
Net income vs. cash flow
An important nuance: net income is not cash. Subscription businesses that prepay annual plans collect cash up front but recognize revenue (and net income) ratably over the year — meaning a company can be cash-flush and net-income-negative simultaneously. The income statement and the cash flow statement tell two different but equally important stories.
How subscription merchants improve net income
- Reduce CAC payback. The faster customers pay back acquisition cost, the more of their lifetime contributes to net income rather than recovering spend.
- Cut COGS via scale. Subscription volume gives leverage on supplier pricing, fulfillment cost, and packaging.
- Reduce churn. Each retained customer compounds margin without acquisition spend.
- Watch operating expense creep. Subscription businesses often over-staff support and tech as they scale; revisit the org chart yearly.
