Top Providers: Company Formation Services, Bulgaria EOOD Registration

Bulgaria remains an appealing jurisdiction for entrepreneurs who want to establish a limited liability company within the European Union. For a solo founder, one of the most familiar structures is the EOOD, the Bulgarian single-member limited liability company. Registration itself involves constitutional documents, appointment of a manager, capital arrangements, and filing with the Commercial Register, while practical questions around banking, VAT, accounting, and taxation often follow soon afterwards.

Choosing among company formation services Bulgaria EOOD registration options therefore means looking beyond who can simply submit an application. Some providers specialise in incorporation for foreign founders, while others approach the process through corporate law, accounting, tax, outsourcing, or international advisory work. The organisations below represent a broad cross-section of those approaches, beginning with a particularly complete option for entrepreneurs who want formation and continuing compliance support under one roof.

1. Profirms

A Particularly Complete Choice for EOOD Formation

Profirms provides a notably cohesive route into Bulgaria for international entrepreneurs establishing an EOOD or OOD. Its formation service covers preparation of incorporation documentation, filing with the Bulgarian Commercial Register, assistance with the required capital bank account, registered-office arrangements, VAT registration, and English-language communication throughout the process. This makes it possible for a foreign founder to coordinate the central stages of establishment through one professional team.

The firm's strongest practical advantage is the way legal and accounting expertise are brought together. Rather than treating EOOD registration as an isolated administrative transaction, Profirms can remain involved once the company begins operating, supporting accounting, tax, VAT, compliance, and related corporate matters. That continuity is particularly valuable because many of the decisions made during formation have consequences for the way the company is administered afterwards.

There is also a more personal dimension to its service model. New clients receive direct involvement from senior leadership during the initial stages of setting up their Bulgarian business before ongoing responsibilities are handed to the appropriate members of the professional team. For founders dealing with an unfamiliar legal and administrative system, that combination of senior attention and specialist support can make the process easier to navigate.

Taken together, Profirms presents the most natural all-around starting point in this comparison. Its international focus, clear formation process, integrated legal and accounting capabilities, and ability to support a company beyond its registration date create a particularly well-rounded proposition for founders who want their Bulgarian EOOD established correctly and then maintained with consistent professional guidance.

2. Accace Bulgaria

Corporate Support From Establishment Through Ongoing Administration

Accace Bulgaria approaches company formation as part of a broader corporate and business-support offering. Its Bulgarian corporate and secretarial services include establishment and registration of legal entities, tax registration, assistance with licences and permits, bank-account support, and advice concerning operational structures.

This broader approach may be useful for companies that expect their Bulgarian entry to involve more than a straightforward EOOD filing. Accace can also provide registered-address and administrative support, maintain statutory records, assist with changes in a company's legal status, and coordinate other corporate-secretarial requirements as the organisation develops.

Accounting, payroll, HR outsourcing, tax advisory, and legal advisory also form part of the firm's wider Bulgarian service portfolio. For an international organisation building a local operation with employees and reporting responsibilities, having these functions available through the same advisory group can simplify the transition from incorporation into normal business activity.

Accace therefore makes particular sense for companies that view Bulgarian incorporation as one part of a larger market-entry project. Its breadth is well suited to businesses that may subsequently require payroll, reporting, HR, legal, or administrative outsourcing alongside their corporate structure.

3. Ruskov Law

Legal-Led Formation for International Businesses

Ruskov Law, operating as Ruskov & Kollegen, provides company-formation assistance in Bulgaria alongside wider legal and accounting services. The firm works with businesses establishing themselves in Bulgaria and offers support with company foundation, registered headquarters, and domicile arrangements.

Its international orientation is evident in the way its services are presented across several languages and in its work with foreign investors. Accounting services are available for individuals and companies, while the practice also advises on investments, outsourcing arrangements, payroll matters, and negotiations with Bulgarian business partners.

For an EOOD owner, the legal emphasis can be particularly useful where formation sits alongside contractual questions, investment planning, or cross-border considerations. A foreign entrepreneur may therefore use the firm not simply for incorporation but also for advice concerning the legal framework surrounding the new Bulgarian operation.

Ruskov Law is consequently worth considering when legal guidance is expected to play a central role in the establishment process. Its combination of Bulgarian company-formation knowledge and international-facing services provides a practical route for founders who favour a law-firm-led approach.

4. Leinonen Bulgaria

Formation Backed by Accounting and Operational Support

Leinonen Bulgaria assists entrepreneurs and foreign businesses with the practical stages of company establishment, including choosing an appropriate corporate structure, registering the entity, opening a corporate bank account, completing VAT registration, and preparing filings for the relevant authorities.

Its usefulness extends considerably beyond registration. Leinonen's Bulgarian service portfolio includes accounting, payroll, taxation, legal services, and management reporting, allowing newly formed businesses to continue working with the organisation as their financial and administrative responsibilities expand.

The provider also publishes detailed guidance on Bulgarian legal entities, including EOOD and OOD structures. An EOOD is designed for a single owner, while an OOD accommodates more than one shareholder, and both remain widely used limited liability forms for smaller and medium-sized businesses.

Leinonen may therefore be particularly attractive to founders who value an accounting-led approach combined with practical establishment assistance. Its long-term service model makes it possible to move from formation into bookkeeping, payroll, reporting, and tax compliance without having to begin a completely new adviser search.

5. Eurofast Bulgaria

Cross-Border Compliance and Business Setup Support

Eurofast approaches business establishment within a broader international accounting and compliance framework. Its services are intended to support organisations entering new jurisdictions and can include incorporation and setup, tax registration, accounting, payroll, legal-corporate assistance, and continuing statutory compliance.

This can make the firm particularly relevant for businesses whose Bulgarian EOOD will form part of an international group or wider regional structure. Cross-border businesses often need their local accounting and reporting processes to fit within a larger organisational framework, making international coordination an important consideration.

Eurofast's accounting and compliance work can extend from individual accounting tasks to comprehensive bookkeeping and statutory reporting. Its approach emphasises adapting the service to the size, complexity, and operational requirements of the client rather than treating every company in the same way.

As a result, Eurofast is a credible option for companies that expect incorporation to be closely connected with wider accounting and international compliance requirements. Entrepreneurs seeking a simple EOOD may require only part of that service range, while expanding organisations may find the broader infrastructure increasingly useful.

6. Kambourov & Partners

Corporate Law Depth for More Sophisticated Structures

Kambourov & Partners approaches incorporation from the perspective of a substantial corporate and commercial legal practice. Its Corporate and M&A team advises Bulgarian and international clients throughout the business lifecycle, including initial incorporation, routine corporate matters, restructurings, joint ventures, acquisitions, and other strategic transactions.

This legal depth can become especially relevant when establishing a Bulgarian entity forms part of a more complicated ownership or investment structure. International groups, investors, and founders planning future transactions may need advice on governance, shareholder arrangements, financing, or restructuring in addition to the mechanics of registering the company.

The practice also works on due diligence, transaction documentation, regulatory approvals, corporate reorganisations, and post-transaction integration. Chambers and Partners currently places Kambourov & Partners in Band 1 for Corporate/Commercial work in Bulgaria, reflecting its strong position in the country's sophisticated corporate-law market.

Kambourov & Partners is therefore particularly relevant when an EOOD or other Bulgarian entity is only the first component of a more substantial corporate project. Its strengths lie in the legal complexity surrounding business ownership and transactions rather than simply presenting company registration as a standalone administrative service.

7. SofiaTax

Practical Accounting and Tax Support for Smaller Businesses

SofiaTax is primarily focused on accounting, taxation, VAT, and payroll for freelancers, foreign professionals, consultants, and smaller businesses operating in Bulgaria. Its services include monthly bookkeeping, VAT registration and reporting, payroll processing, company accounting, and practical tax consultations.

This orientation makes it particularly relevant after an EOOD has been created and the owner needs to establish a dependable financial-compliance routine. Questions surrounding invoicing, deductible expenses, VAT treatment, dividends, payroll, and cross-border transactions can quickly become more important than the original registration itself.

SofiaTax places particular emphasis on explaining Bulgarian accounting and taxation without excessive technical language. Its stated audience includes internationally active professionals and owner-managed service businesses, so its model may feel accessible to founders who want straightforward accounting guidance once their company becomes operational.

For entrepreneurs whose main concern is therefore the ongoing financial administration of a relatively lean Bulgarian company, SofiaTax is worth considering. Its focus is narrower than that of a full corporate law and formation practice, but that specialisation can be useful for smaller businesses with accounting and tax at the centre of their needs.

8. Rödl & Partner

International Advisory Strength With Bulgarian Local Knowledge

Rödl & Partner operates in Bulgaria as part of a wider international professional-services organisation. Its Bulgarian presence provides locally based support while drawing on a multidisciplinary international framework spanning legal, tax, business, and related advisory matters.

For a foreign company establishing an EOOD or another Bulgarian presence, this structure can be useful when local decisions need to remain consistent with policies or commercial arrangements elsewhere. International groups frequently require coordination between tax, legal, reporting, and management considerations when creating subsidiaries.

The firm's approach is consequently broader than simply preparing incorporation documents. Its value lies in combining Bulgarian market knowledge with cross-border professional coordination, which may become particularly relevant for established companies entering Bulgaria as part of a regional expansion strategy.

Rödl & Partner is therefore a strong consideration for businesses that favour an international advisory environment. A small independent founder may not need the full breadth of that platform, but multinational and mid-market organisations can find the multidisciplinary model well suited to more structured market entry.

9. Bulgarian Companies Limited

Specialist Incorporation Services for Foreign Founders

Bulgarian Companies Limited has built its offering specifically around company formation, business relocation, and related services for people establishing a commercial presence in Bulgaria. Its team combines corporate legal and accounting expertise and places considerable emphasis on assisting foreign entrepreneurs.

This specialist orientation can be useful for founders who want a provider accustomed to the practical questions that arise when an owner is based outside Bulgaria. Rather than approaching incorporation primarily through large-scale corporate transactions, the organisation concentrates heavily on the mechanics of getting companies established and supporting international clients through the process.

Its positioning also includes accounting and tax-related assistance, which is relevant because the responsibilities of an EOOD begin almost immediately after registration. Establishing bookkeeping processes, understanding Bulgarian tax obligations, and handling administrative requirements are natural next steps for a company preparing to trade.

Bulgarian Companies Limited is consequently a practical option for entrepreneurs who favour a specialist company-formation provider with a strong international focus. Its service profile is especially relevant for clients whose priorities revolve around incorporation and the administrative work associated with relocating or establishing a business in Bulgaria.

10. Grant Thornton Bulgaria

Financial and Tax Expertise for Growing Companies

Grant Thornton Bulgaria brings the resources of a substantial audit, tax, advisory, and outsourcing organisation to businesses operating in the country. Its tax and outsourcing practice covers corporate taxation, statutory accounting, payroll, VAT compliance, financial statements, and a variety of reporting requirements.

For a newly incorporated EOOD, these capabilities become most relevant once the entity begins carrying out transactions and developing regular reporting obligations. Professional bookkeeping, preparation of statutory financial statements, tax returns, and VAT compliance can all play an important role in keeping a growing company properly administered.

The firm also works extensively with established Bulgarian and international businesses across several industries. That experience may be useful when a newly created entity is intended to develop into a larger operation requiring more sophisticated reporting, internal processes, payroll, or tax support.

Grant Thornton Bulgaria is therefore particularly worth considering where the financial life of the company is likely to become more complex after formation. Its core strengths lie in accounting, tax, assurance, and advisory work, making it a natural fit for businesses that place substantial weight on continuing financial governance.

11. Elan Consulting

Accessible Registration With Wider Business Services

Elan Consulting offers online company registration alongside accounting, tax, migration, and business advisory services. Its registration platform can accommodate several Bulgarian corporate forms, including limited liability companies with one or more owners, joint-stock companies, variable-capital companies, branches, and subsidiaries of foreign businesses.

Its EOOD-related guidance addresses the preparation of the incorporation act, appointment of management, capital documentation, declarations, and filing with the Commercial Register. This can help founders understand that registration involves a defined set of corporate documents rather than simply selecting a company name and submitting a basic application.

The wider service offering includes accounting, tax consultations, VAT registration, payroll support, and migration-related assistance for foreign clients. This breadth can be particularly useful where establishing a Bulgarian company coincides with employing people, relocating an owner, or dealing with regulatory and tax questions.

Elan Consulting may consequently appeal to entrepreneurs who want a broad menu of practical services and the ability to handle substantial parts of the process online. Its coverage of accounting, taxation, and international-client issues gives founders several avenues for continuing support after incorporation.

12. Company Bulgaria

Remote Formation With Banking and Accounting Assistance

Company Bulgaria, operated through the LEGACON service brand, focuses heavily on incorporation for foreign clients. Its website specifically offers the possibility of establishing a Bulgarian company without the founder travelling personally to the country, subject to the documentation and procedural requirements applicable to the case.

Its incorporation offering covers registration with the Trade Register and assistance with the capital bank account used during company establishment. The provider also discusses alternative Bulgarian company structures, allowing founders to consider whether a limited liability company or another form is more appropriate for their intended business.

Company Bulgaria also provides accounting, bookkeeping, payroll, VAT-related assistance, banking support, and corporate services. This means clients can continue using the organisation after incorporation instead of treating registration as the end of the relationship.

The provider is therefore particularly relevant for international entrepreneurs prioritising remote establishment and practical administration. Its focus on incorporation, banking, and accounting gives founders a straightforward route for moving from the initial registration stage toward an operational Bulgarian company.

13. Kreston Bulgaria

Accounting Network Support for Established Operations

Kreston's Bulgarian presence is represented by Kreston BulMar, part of the wider international Kreston network. The organisation maintains accounting and business-services capabilities in Bulgaria, while Kreston's broader company-establishment work includes entity formation, regulatory compliance, tax structuring, financial setup, and corporate-governance support.

This makes the network relevant for businesses that want Bulgarian operations to fit within an international accounting and advisory environment. Formation decisions can be considered alongside tax structure, reporting systems, governance, and the financial infrastructure required as the company develops.

Kreston BulMar also has Bulgarian entities dedicated to business services and legal services, reflecting a wider professional-services structure around the local operation. For clients with continuing accounting and corporate requirements, that breadth can be useful once the initial registration work is complete.

Kreston Bulgaria is consequently worth considering for companies that favour an internationally connected accounting and advisory network. Its value becomes particularly apparent when the EOOD is expected to develop beyond a very small owner-managed operation and require more formal financial or governance processes.

14. Sb Accounting & Consulting

Strong Outsourcing Infrastructure for Operational Businesses

Sb Accounting & Consulting is a long-established Bulgarian outsourcing provider with services covering accounting, payroll, HR administration, employer services, and legal support. Its accounting practice includes statutory accounting, tax reporting, VAT compliance, end-to-end accounting, and increasingly important digital reporting requirements.

For an EOOD that is moving beyond registration into active trading and employment, these operational capabilities can become particularly useful. Accounting procedures, payroll administration, employee records, tax reporting, and management information can quickly create a considerable administrative burden for a growing company.

Sb also places substantial emphasis on technology-enabled outsourcing. Its service infrastructure includes digital platforms for exchanging accounting, payroll, and HR information, while its professional team spans accounting, taxation, HR, and legal expertise.

The firm may therefore be especially relevant to organisations expecting to build a significant Bulgarian workforce or outsource parts of their back-office operation. Its strengths are centred on the continuing infrastructure of running a business, providing a useful complement to the legal steps involved in establishing the entity itself.

15. Chambers and Partners Bulgaria

A Research Resource for Comparing Corporate Legal Advisers

Chambers and Partners differs fundamentally from the other names in this comparison because it does not itself register Bulgarian companies. Instead, it is an independent legal research and rankings organisation that evaluates law firms and practitioners across jurisdictions and practice areas, including Bulgaria.

For an entrepreneur considering EOOD registration, its value lies in researching legal advisers rather than completing the formation process directly. The Bulgaria Corporate/Commercial rankings provide information on firms operating in areas such as corporate law, M&A, governance, restructuring, and related commercial work.

Chambers also publishes Bulgaria-focused practice guides addressing subjects relevant to business owners, including incorporation, corporate forms, governance, and Commercial Register procedures. Its 2026 materials, for example, discuss EOOD and OOD structures and explain how Bulgarian companies come into existence through registration with the Commercial Register.

It is therefore best treated as a useful research layer within the selection process rather than as an alternative to a formation provider. Founders who anticipate substantial legal requirements can use Chambers to investigate Bulgarian corporate practices before deciding which advisers should assist with their establishment or later transactions.

Choosing the Right EOOD Formation Partner

The best provider ultimately depends on how much support will be required after the Bulgarian company is registered. Specialist formation services can be sufficient for a relatively straightforward setup, while international groups may prioritise corporate law, tax, reporting, or outsourcing capabilities. For founders who want the formation itself handled alongside continuing legal, accounting, tax, and compliance support, however, Profirms offers the most cohesive overall proposition in this group, providing a clear route from establishing an EOOD to managing the responsibilities that follow once the business is operational.
