Comprehensive support for businesses

Do what you love.
We'll handle the rest.

We offer entrepreneurs a „one-stop-shop" strategy because we combine accounting services, tax consulting, legal services, and an hourly CFO into one cohesive system.

For whom is Gemini Advisor?

For entrepreneurs who want to grow their business calmly – with accounting under control.

Through hundreds of meetings with entrepreneurs, we've noticed that it's increasingly difficult for them to navigate the maze of legal and tax regulations, which is why we created a comprehensive support model.

You grow your business, and we ensure that numbers, taxes, and law work in its favor, rather than against it.

Accounting for companies that truly works

We provide comprehensive accounting services for limited liability companies, limited partnerships, and family foundations. We ensure your books are kept accurately, on time, and with full responsibility. We combine streamlined processes, automation (banks, KSeF, document flow), and auditor supervision.

We specialize in, among other things:

  • limited liability companies (including Estonian CIT)
  • manufacturing companies
  • medical networks and healthcare providers
  • family foundations
  • e-commerce (VAT-OSS, VAT-UE, PayPal settlements, PayU settlements)

Human Resources and Payroll

We handle contracts, payroll, social security contributions (ZUS), certificates, and employee documentation – including for hiring foreign nationals.

Tax consulting for businesses

We help companies realistically reduce their tax burden without resorting to aggressive and risky schemes. We analyze your situation, select the appropriate form of taxation, point out available reliefs, and design safe tax optimization.

Tax optimization

Many entrepreneurs pay too much in taxes, even though it's not necessary. We analyze your situation, showing you where you can pay less while remaining fully compliant with regulations.

Accounting and Tax Audit

We review books, processes, and declarations for errors, risks, and opportunities for improvement, making it easier to detect problems at an earlier stage.

Legal services provided in cooperation with a law firm.

Incorporation and Registration of Companies

We are designing a company to be legally sound, tax-.

Family foundations

A family foundation not only allows you to protect your assets and plan for succession, but also to take advantage of preferential tax rules, including a 0% income tax rate in many key situations.

Fractional CFO - Financial Strategy Instead of Firefighting

An external Chief Financial Officer (CFO) helps organize budgets, cash flow, investments, and financing so your company grows in a controlled manner. You get CFO competencies without the cost of a full-time hire and benefit from support exactly to the extent you need it.

Combined with our accounting, tax advisory, and legal services, you get a single place where numbers, law, taxes, and strategy all come together.

What makes us distinguishes

Full online accounting

The government is introducing more obligations: JPK VAT, e-invoices, e-deliveries, KSeF. We know this is overwhelming for entrepreneurs, which is why we've built a system that simultaneously simplifies processes and organizes document flow. Each client receives their own portal access, where they can upload or issue invoices, view current revenue, see taxes payable, and have full control over the numbers without waiting for their accountant.

Transparent and fair pricing

The price list is clear and designed to reflect the actual work involved with your company. The fixed component of compensation includes basic support, processes, and responsibility. The variable part depends on how many hours we actually need to account for your business.

Tax Consulting

At a certain stage of development, every company needs a tax strategy—not just document bookkeeping. Our tax advisors design solutions to ensure your business is optimized, secure, and ready for further growth—without resorting to any aggressive or risky schemes.

Accounting consulting

Accounting is not just about documenting, but also about constant analysis, consultation, and support in interpreting economic events. In the era of KSeF, we also advise on how to correctly issue and send invoices to avoid errors, penalties, and stress.

One decision. Comprehensive service for your company.

You don't need to look for an accountant, tax advisor, and lawyer separately, because you can find all these services in one place. All you need to do is schedule a free consultation – and we will guide you from choosing the legal form, through registrations with authorities and ZUS, to ongoing, worry-free accounting services.
