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 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.

Too broad product selection initially — start with 3-5 SKUs
3
No email list building from day one
4
Ignoring Amazon FBA as distribution channel
5
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 — typically a low-to-mid four-figure annual premium; 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 requires a low-to-mid five-figure investment, covering initial inventory, a Shopify (or comparable) monthly subscription, product photography, and an initial marketing budget. Dropshipping models can launch for a fraction of that — often a low-to-mid four-figure outlay — but operate at noticeably lower margins.

Shopify is the easiest path to launching quickly with built-in hosting and payments — its monthly subscription tiers (https://www.shopify.com/pricing) scale with feature depth. 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 minimal (often a low four-figure outlay), but margins are noticeably thinner than inventory-based stores, where private-label products with held inventory command meaningfully higher margins and stronger branding. Dropshipping is also extremely competitive.

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.
