Starting a business doesn't have to begin with queues and paperwork. Today, it's possible to create a 100% company online with legal security, predictable deadlines, and controlled costs.

This practical guide explains, from start to finish, how to create an online business: which corporate structure to choose, what documents are required, what the legal steps are, how much it costs, how to avoid mistakes, and how to speed everything up with remote professional support. 

Why create a 100% company online?

Before the list, a central idea: digital technology reduces friction without compromising the validity of actions. Here are the direct benefits of this model of constitution.

• Speed: Electronic submissions, digital signatures, and simplified scheduling.

• Savings: Fewer trips, fewer absences, and predictable administrative costs.

• Traceability: Electronic records, receipts, and proof of purchase at every step.

• Scalability: Standard templates and repeatable processes when there are multiple companies.

What type of society should we choose?

Creating a 100% company online requires a good foundational decision. In Portugal, the most common options are:

• Limited Liability Company (Lda.): Flexible, suitable for micro and small businesses. Simple management rules.

• Single-Member Limited Liability Company: Single-member equity version. Ideal for starting out alone with limited liability.

• Public Limited Company (SA): Higher capital and governance requirements. Suitable for projects with significant investment.

Practical tip: align the legal structure with the business risk, financing needs, and desired governance.

Creating a 100% company online: legal steps

To make things easier, we present the typical sequence for creating a 100% company online. Follow each step carefully.

1. Define company name and business purpose: Check the availability of the name and describe the object accurately. Creating a 100% company online requires a firm description to avoid rejections.

2. Identify partners and management/corporate bodies: Name, address, tax identification number (NIF), and capital percentages. Also prepare any necessary powers of attorney.

3. Choosing a location: lease agreement, contract of loan for or validated digital address.

4. Prepare articles of association or company bylaws: Capital clauses, cash/in-kind contributions, quorum and preference rules.

5. Digital signatures: Ensure a Citizen Card with an active PIN or Digital Mobile Key for all grantors.

6. Application submission: Electronic submission of the contract/statutes and supplementary data.

7. Commercial registration: After the conference, the company is registered and obtains electronic certificates.

8. Commencement of activity in Finance: Communication regarding tax status and VAT regime.

9. RCBE – Central Register of Beneficial Owners: Online submission is mandatory immediately after registration.

10. Bank account and payment methods: Account opening, IBAN and payment methods.

11. Certified invoicing and data protection: Choose certified software and prepare the minimum GDPR compliance documents.

Essential documents

A quick introduction: preparing everything beforehand speeds up the formation of the company and avoids additional requirements.

• Identification of partners and administrators/managers: Citizen card or passport, tax identification number (NIF), and address.

• Powers of attorney, if a partner does not sign directly: They must include special powers to form a company.

• Proof of registered office: lease agreement, loan agreement, or suitable declaration.

• Draft/statutes: Partnership agreement with clauses tailored to the business.

• Digital certificates: Citizen card with active PIN or Digital Mobile Key.

Typical costs for creating a 100% company online

Prices vary depending on the legal structure and additional services. Generally, when creating a 100% company online, you should expect:

• Registration fees: base value of the company registration, plus fees for additional acts.

• Legal and accounting services: Incorporation packages, templates and submissions, and initial accounting setup.

• Software and certifications: Certified invoicing license, digital signature, and possible trademark.

Average terms

Creating a 100% company online can be completed in just a few business days once the documentation is ready. The main variables are the signatures and registration validation. Starting operations and registration with the RCBE (Register of Beneficial Owners) follow quickly after registration certification.

Common mistakes that delay the business creation process.

Before the list, emphasize: small details cause big delays. Avoid:

• Vague social objects: Generic descriptions lead to demands. Be specific.

• Lack of powers in powers of attorney: Powers of attorney without special powers to incorporate the company delay the process.

• Poorly proven thirst: Inconsistent contracts lead to rejections.

• Missing active PINs: Without an active PIN or CMD, it is not possible to sign up and create a 100% company online.

• Statutes copied without adaptation: Preference clauses, share transfer agreements, and quorum requirements must reflect reality.

Company and brand: do not confuse them.

A brief note: a firm name is the legal name of a company; a brand is its distinctive commercial sign. Creating a company includes validating the firm name. Brand protection is done through a separate procedure and can be parallel to it.

Immediate obligations after creating a company.

To ensure the operation starts smoothly, address these issues immediately after registration.

• Finances: Start of activity, VAT regime, eligibility for exemptions or special regimes.

• Social Security: The framework for managers/administrators and workers.

• RCBE: Submission is mandatory, and updates will be required whenever relevant changes occur.

• Billing: Implement certified software and billing series.

• GDPR and file: Privacy policy, minimal processing, and treatment map.

Sector-specific licenses and communications

Creating a 100% company online does not exempt you from obtaining licenses where applicable. Before operating, confirm that your CAE requires:

• Prior notification or municipal licensing: Activities that have an impact on urban planning, noise, or special hours.

• Specific records: tourism, restaurants, transport, health, education.

• Technical requirements: HACCP, security, mandatory insurance.

Basic contracts to get started

A brief introduction: standardizing contracts gives you speed and consistency, so be prepared:

Service contracts: Scope, service levels, intellectual property, confidentiality.

Employment/teleworking contracts: Equipment, timing, telematics and data protection.

Website and app terms and policies: Terms of use, privacy, cookies and consent.

Cloud and software providers: SLA, backups, security, and subcontractors.
