Mantichoras Offer

Accounting for Sole Proprietors

Leaving your full‑time job to start your own business? Been serving clients for years — or, on the contrary, just taking your first steps as a freelancer?

Worry-free Accounting

Focus on your business — we’ll take care of the rest

Whatever the scale and field, one thing is certain: you want to focus on your work, projects and new business relationships — not on settlements and ever‑changing regulations. Entrust your operations to the experts at Mantichoras Accounting Office and be sure everything is fully compliant. Together, we’ll find the best solutions for your business!

Mantichoras Accounting Office — Your Trusted Partner in Finance

For sole proprietors, sound bookkeeping matters for two reasons: to meet legal and tax requirements — and to avoid real financial losses from a poor choice of taxation form or failing to use legally available reliefs.

If you’re just starting a one‑person business, we’ll clearly explain the main tax options, their pros and cons, clarify ZUS reliefs and help with business registration. You can count on our full support!

What sets us apart?

Many accountants focus solely on recording documents correctly and see no need to get involved in the company’s affairs. At Mantichoras we operate differently: we don’t want to be just an “invoicing machine” — our goal is to genuinely help the client.

We’ll guide you through the maze of regulations and find solutions that translate into better results.

We stand out for:

  • An individual, flexible approach — we account for your needs, industry and market.
  • Reliable settlements, fully aligned with your chosen taxation method
  • Security and confidentiality — your documents are protected from unauthorised access.
  • A wide range of services.
  • Smooth, responsive communication.

We safeguard our clients’ interests by ensuring all actions are fully compliant.

We also inform you of any changes in Polish or EU regulations so you have time to prepare in advance.

We know there are no one‑size‑fits‑all solutions — not only does each industry differ, but so does each company. That’s why we work with you and for you.

We value honesty and transparency
