How Much Does It Cost to Start an Online Store?
Starting an online store typically costs $5,000 to $50,000 up front, with inventory as the biggest variable. Revenue Map's e-commerce model presets assume a starting investment of $50,000 for a store that funds inventory, a proper site, and several months of paid acquisition from day one.
E-commerce is cheaper to open than SaaS but harder to run at a loss, because every order carries real cost of goods, shipping, and returns. Storefront software is a rounding error next to the two lines that dominate: your first inventory purchase and your first-year ad budget. Dropshipping removes the inventory line but compresses margins, and print-on-demand sits in between.
The presets behind Revenue Map's e-commerce model assume a $85 average order value with cost of goods near 50%, a $1.20 cost per click, and ad budgets that ramp from $5,000 per month at launch to $25,000 at scale. Those assumptions frame the ranges below: what it takes not just to open a store, but to feed it traffic long enough for repeat purchases to kick in.

What Moves the Number
Inventory model
Holding stock ties up thousands of dollars before the first sale but protects margin; dropshipping starts near zero but gives away 20 to 30 points of margin and control over fulfillment. This single choice moves the up-front number more than anything else.
Category economics
Revenue Map's presets model fashion at a $65 average order value with 55% cost of goods and a 15% return rate, while digital products start near $25 with almost no COGS and no returns. High-return categories need a bigger cash buffer for the same revenue.
Paid traffic dependence
At the preset $1.20 cost per click and a 2.5% click-to-purchase rate, each new customer costs roughly $48 of ad spend before any organic traffic. Stores that launch with an audience, or build organic channels early, cut the largest line in the budget.
Repeat purchase rate
A first order rarely pays back its acquisition cost alone. The presets move repeat purchase rates from 15% at launch to 30% at scale, and the faster you climb that curve, the less total marketing cash you burn reaching profitability.
