How to start an agency: which model fits – and how to get started

Updated: 28 September 2026 · Creator Heave

You start an agency in six steps: choose a niche, define your offer and price, sort out your legal form and business registration, set up contracts, win your first clients and then build your team and tools. Most agencies start with little capital because they sell services – it only gets expensive once you have a team. Which type of agency fits depends on your skills and your network.

How to start an agency in 6 steps

  1. 1

    Choose a niche

    Who do you work for, and what problem do you solve? A clear niche makes marketing and pricing easier.

  2. 2

    Offer and price

    What exactly do you deliver, in what scope, at what price? Calculate beforehand what is left after costs.

  3. 3

    Legal form and registration

    Sole trader or limited company – depending on liability, partners and revenue. The rules depend on your country: in Germany, for example, you choose between sole proprietorship, UG or GmbH, register a trade (Gewerbe) and register with the tax office. Ideally with a tax adviser.

  4. 4

    Contracts

    Written contracts with clients and staff: services, term, termination, data protection.

  5. 5

    First clients

    Network, referrals, content and direct outreach. Your first references matter more than a perfect logo.

  6. 6

    Team and tools

    Only once the demand is there: freelancers or employees, CRM, project and billing software.

No legal or tax advice. Rules on legal form, business registration and tax depend on your country – please consult a qualified professional.

FAQ: starting an agency

How do I start my own agency?

Choose a niche, define your offer and price, sort out your legal form and business registration, set up contracts and win your first clients. Team and software come once demand is there. It pays to get tax advice on taxes and legal form right from the start.

How much does it cost to start an agency?

Setting up is usually inexpensive: business registration, website, software and advice. A limited company typically costs more – in Germany, for example, a GmbH or UG also requires share capital and notary fees. The biggest cost later on is staff or freelancers – so only grow once you have clients.

What does an agency do?

An agency takes on tasks for clients who lack the time or know-how – and is paid through a retainer, per project or with a revenue share. Its assets are expertise, processes and trust.

What does an influencer management agency do?

It represents influencers towards brands: it negotiates collaborations, reviews contracts, and plans content and the long-term career. It is usually paid through a commission on the collaborations it brokers.

Do I need a limited company to start an agency?

No. Many agencies start as sole traders. A limited company (in Germany, for example, a GmbH or UG) limits liability and can make sense for tax purposes, but involves more admin. The options depend on your country – a tax adviser is the best person to help you decide which form fits.
