Frequently asked questions

Investment to launch e-commerce in San Diego?

Initial investment 23K USD-230K USD USD: Shopify or WooCommerce development (3-15K USD), initial stock (30-50 % of budget), professional product photos, visual identity, insurance, ad budget (10-30K USD for first 3 months), logistics (warehouse or 3PL).

How to build acquisition in San Diego?

Typical 2025 mix: 30-45 % paid (Meta Ads, Google Ads, TikTok Ads, CAC 25-80 USD), 20-30 % SEO (long-term, free after 5-15K initial investment), 15-25 % marketplaces (Amazon, eBay), 10-15 % email marketing (recurring), 5-15 % influencers and partnerships. Target ROAS 3-5x on paid.

Sell on own store or Amazon?

Optimal mix by category: Amazon captures mass (60-80 % of US product searches, 25-40 % in Europe) with reduced margins (12-18 % commissions + FBA + ads). Own store keeps brand, data and margin but requires generating traffic. Hybrid model (50/50) limits Amazon dependence and captures both flows.

What net margin to target in e-commerce?

Target net margin: 8 % at steady state. Typical breakdown: gross margin 40-55 %, paid acquisition -20-30 %, logistics and payment fees -5-8 %, payroll and structure -5-10 %, other -2-5 %. Profitable e-merchants invest heavily in year 1-2 (negative margin) then recover from year 3+.
