How do I register a small online shop in Mexico and issue invoices legally?

Congratulations on the growth of your handmade products business. Transitioning from informal sales to a properly registered business in Mexico is the best step to scale your operations, build trust with larger clients, and issue valid tax invoices (CFDI) without facing penalties from the Mexican Tax Authority (SAT).

To set up your business legally and securely, we need to address three main pillars. Here is the strategic roadmap we handle for e-commerce entrepreneurs:

1. Choosing the Right Business Structure (Tax Regime)

Depending on your projected income and whether you want to protect your personal assets, we have two optimal paths:

As an Individual (Persona Física - RESICO): The \"Simplified Trust Regime\" is perfect for starting. It offers incredibly low income tax rates (between 1% and 2.5%).

As a Micro-Corporation (SAS - Sociedad por Acciones Simplificada): If you want to separate your personal assets from your business liability, we can create an SAS. It requires no minimum capital, can be formed with a single shareholder (you), and is done entirely online.

2. SAT Registration & Invoicing (Permits)

Selling handmade goods generally doesn't require special sanitary permits unless they are cosmetics or food. However, you strictly need:

Your RFC (Tax ID) and e.firma (Electronic Signature).

Activation of your Digital Seal Certificates (CSD) to start issuing electronic invoices (CFDI 4.0) directly from your website or SAT's portal.

3. Brand Protection (IMPI Registration)

Selling on social media exposes your brand to copycats. Registering your brand name and logo with the Mexican Institute of Industrial Property (IMPI) is crucial. It gives you the exclusive legal right to use it nationwide and allows you to take down fake profiles or competitors using your name.

Timeline: The process timeline largely depends on the SAT. Getting an appointment for your e.firma can take anywhere from 1 to 3 weeks. Once we have that, incorporating an SAS takes about a week, and activating your invoicing system takes 24 to 48 hours.

Next Steps:

At Eficiencia Legal Colectiva / Praevian Risk Partners, we can manage this entire corporate structuring for you. Please reach out to schedule a brief consultation so we can determine the exact tax regime that benefits your specific profit margins and begin the registration process.
