Licenses & Permits in California

General Business License

California does not have a statewide general business license, but most cities and counties require a local business license or business tax certificate. Businesses must register with the California Secretary of State for entity formation, obtain a seller's permit from the California Department of Tax and Fee Administration if selling taxable goods, and register with the EDD for payroll taxes if employing workers. San Francisco, Los Angeles, and other major cities have their own business registration and tax requirements.

AB 2221 (2022) expanded rights for home-based food businesses under the Homemade Food Operations Act. Some cities, including Los Angeles, have updated their home occupation rules to allow more types of businesses post-pandemic.

Ignoring Amazon FBA as distribution channel

Insufficient inventory for demand spikes and stockouts

Next Steps to Launch Your E-Commerce Store

1
Form your LLC in California — protects personal assets from product liability claims and separates business finances (filing fee: $70)
2
Register for a California sales tax permit — required for selling online to California residents; economic nexus rules apply in other states
3
Set up your store on Shopify, WooCommerce, or BigCommerce — choose based on product count, budget, and customization needs
4
Open a business bank account and set up Stripe or PayPal for payment processing before sourcing inventory
5
Research suppliers on Alibaba, US-based wholesalers, or print-on-demand (Printful, Printify) depending on your product model
6
Obtain product liability insurance — $500–$2,000/year; required by Amazon FBA and strongly recommended for physical products
7
Set up your accounting with QuickBooks or Xero — track COGS, shipping costs, and platform fees from day one
8
Create a returns/refund policy and terms of service before your first sale — California consumer protection laws apply

Frequently Asked Questions

Starting an e-commerce store typically costs $5,000–$15,000, including initial inventory ($1,000–$5,000), Shopify subscription ($39–$79/month), product photography ($200–$800), and initial marketing budget. Dropshipping models can start for under $1,000 but have lower margins.

Shopify ($39–$399/month) is easiest to launch quickly with built-in hosting and payments. WooCommerce is free but requires WordPress hosting and more technical management. BigCommerce scales well for higher-volume stores. Most new stores start on Shopify.

Dropshipping means suppliers ship directly to customers — no inventory required. Startup costs are under $1,000, but margins are 10–20% vs. 30–60% for inventory-based stores. Dropshipping is extremely competitive; private label products with inventory command better margins and branding.

New stores typically combine paid ads (Facebook/Instagram, Google Shopping) for fast traffic and SEO + content for long-term organic growth. Email capture from day one is essential. Influencer partnerships can drive significant early sales. Organic social media alone rarely generates enough volume.
