Core position: a safe business launch in Greece is not limited to receiving a tax number or completing a registry filing. It is a legal decision about responsibility, capital, partners, premises, licensing, customer terms, suppliers, employees and the evidence that will protect the business when a disagreement appears.

This guide is informational and does not replace tailored legal advice. The same activity can create different obligations depending on the business activity code, the premises, the use of personal data, the way services are sold and whether employees or independent contractors are involved.

1. Legal form and liability

The first question is whether the business will operate as an individual business, a partnership or a company. The answer affects personal liability, tax and accounting handling, decision making, transfer of shares, entry of investors and the way contracts are signed. Before registration, founders should agree who contributes money, work or assets, who manages the business, how profits are distributed and what happens if a partner leaves.

2. Registry, tax and insurance steps

Formation should be matched with a practical compliance checklist: registry entry where required, tax activation, accounting books, social insurance obligations, professional permits and any sector specific approvals. The legal risk is usually not one missing form, but the absence of a documented sequence that proves the business started correctly and within its approved scope.

3. Premises, permits and operating risk

If the business uses premises, the lease must allow the intended activity and should clarify duration, rent, deposit, repairs, common expenses, signage, early termination and handover evidence. Activities involving food, health, education, regulated professions, transport, data processing or public access may require additional checks before the first sale.

4. Contracts and data protection

Every new business needs basic written terms for customers, suppliers and collaborators. These terms should define scope, price, payment, delivery, delays, liability, cancellation, confidentiality and dispute handling. If the business collects customer, employee or website data, it also needs a lawful basis, transparent notices, retention rules and clear access controls.

5. Before the first transaction

The practical target is simple: no sale, invoice, booking or delivery should happen before the business can prove who operates it, what exactly is offered, under which terms, which permits apply and where the relevant documents are stored. A short legal review at this stage usually prevents expensive corrections later.

Practical legal checklist before launch

Before the first invoice, the founder should treat the launch as a legal file, not only as a tax or registry task. The file should show why the chosen form is appropriate, who manages the business, how partners make decisions, what happens if a partner leaves, how funding is documented and which assets or guarantees remain personally exposed. This is especially important when an IKE, OE, EE or other company form is used with more than one person, because a standard template rarely answers real future disputes.

The business premises must also be checked before money is spent on renovation, rent or equipment. A lease, concession or ownership document should support the registered seat, and the permitted use should match the real activity. For regulated sectors, the tax start and the KAD are not enough. The founder should confirm whether a notification, license, responsible professional, technical file or health and safety requirement is needed before the business opens to the public.

Contracts should be ready before the first sale or cooperation. Customer terms, supplier terms, partner agreements, confidentiality clauses, intellectual-property clauses and website policies reduce uncertainty when payment, delivery, returns, defects or data handling become disputed. A new company should also know who owns the logo, domain, photographs, software, database, social accounts and commercial name. Payment alone does not always transfer intellectual-property rights unless the agreement says so clearly.

A practical launch file includes the constitution or start declaration, GEMI and AADE evidence, insurance registration where required, lease or seat evidence, license or notification proof, customer and supplier contract templates, privacy notice, cookie/consent records, processor agreements, brand checks and a simple risk note. Legal review is most useful before the founder signs a long lease, accepts investment, hires staff, starts online sales or relies on a brand that must be protected.
