Frequently Asked Questions

What is the cheapest way to start an online store?
Shopify Basic on annual billing (~$29/mo) is the easiest entry point with the lowest setup friction. WooCommerce has no core platform fee but requires hosting ($25–$100/mo) and meaningful setup time. For a micro-store under 25 products with minimal budget, Squarespace Commerce Basic ($28/mo annual) is worth comparing.
What is not included in these setup cost estimates?
These estimates cover one-time setup only. Ongoing costs to budget separately: platform subscription ($29–$399+/month), payment processing fees (2.9%+$0.30 per transaction for Stripe/PayPal), Shopify transaction fees if not using Shopify Payments (2% on Basic), and app/plugin subscriptions ($50–$300+/month for a full-featured store).
How much does a Shopify store really cost per year?
A basic Shopify store on annual billing runs ~$348/year for the subscription. Add a premium theme ($0–$350 one-time), essential apps ($50–$200/month), and domain ($12/year). A realistic fully running Shopify Basic store costs $1,000–$3,500 in year 1 including setup, and $800–$2,500/year ongoing.
Is WooCommerce cheaper than Shopify?
WooCommerce has no core platform fee, but hosting ($25–$100/mo), plugin stack ($100–$500/year), and maintenance cost mean WooCommerce is only cheaper when the store is small, plugin count stays low, and the owner manages updates themselves. At scale or with a developer, Shopify often wins on total operational cost.
How long does it take to build an ecommerce store?
A DIY Shopify setup for a small store (25–100 products) takes 2–6 weeks of owner time. A freelancer-built store on Shopify or WooCommerce typically takes 4–10 weeks. A custom build can take 3–9 months. Catalog size and custom integrations are the main timeline drivers.

Methodology

Setup cost estimates reflect one-time project costs to launch a functional ecommerce store — not ongoing subscription fees. Platform subscription costs are shown separately in the result summary. Estimates are based on 2026 US freelancer and agency market data. Monthly platform fees shown are approximate mid-tier figures; verify current pricing at each platform's website before committing.
