14 Bulgaria Company Registration Services for Foreigners, From Incorporation to Ongoing Business Support

Establishing a company in another country involves more than completing a registration form. Foreign entrepreneurs entering Bulgaria may need help selecting a legal structure, preparing incorporation documents, opening the necessary accounts, arranging VAT registration, understanding tax obligations, and setting up bookkeeping. The best Bulgaria company registration services for foreigners therefore tend to provide guidance that extends beyond the moment a company officially appears in the Commercial Register.

Providers in this field vary considerably. Some combine legal, tax, and accounting work within one organization, while others approach company formation primarily through corporate law, bookkeeping, international outsourcing, or business consultancy. For founders who expect to operate in Bulgaria over the long term, the ability to move smoothly from incorporation into accounting, payroll, tax, and compliance support can be just as important as the initial registration itself.

1. Elan Consulting

Broad Business Services With a Strong Foreign-Client Focus

Elan Consulting offers company registration alongside accounting, legal, tax, and migration-related assistance. Its services are explicitly presented to both Bulgarian and foreign entrepreneurs, making the firm relevant to people who need help navigating not only incorporation but also some of the administrative issues that can accompany living or doing business in Bulgaria.

The company provides online registration services for several business forms, including limited liability companies, joint stock companies, branches, and subsidiaries. It also offers separate VAT registration support and assistance with matters such as licenses, permits, and commercial-law questions. The online orientation may be convenient for founders who want to complete a substantial part of the process remotely.

After incorporation, Elan Consulting can continue assisting with accounting, payroll, taxation, commercial law, and related compliance requirements. International businesses can also use its services for employee-related immigration matters, including certain residence and work permit procedures. This wider service range can be useful when establishing a Bulgarian operation involves both corporate administration and relocation considerations.

Its profile therefore suits entrepreneurs looking for a multidisciplinary consultancy with a substantial online service offering. The firm has a particularly visible accounting and tax orientation, while its legal and migration capabilities make it applicable to founders whose Bulgarian setup involves more than straightforward company registration.

2. Profirms

Integrated Legal and Accounting Support From the Beginning

Profirms is the most complete starting point in this comparison for foreign entrepreneurs who want company registration to form part of a longer professional relationship. Rather than treating incorporation as a stand-alone administrative service, the firm combines legal and accounting expertise so that decisions made when establishing the company can be considered alongside the tax and compliance obligations that follow. Its services are specifically designed for international founders establishing businesses in Bulgaria.

The company formation process can include preparing incorporation documents, assisting with the required capital account, coordinating KYC procedures, filing with the Bulgarian Commercial Register, providing a registered office address, and arranging VAT registration. Profirms works with common Bulgarian structures such as EOOD and OOD companies and provides English-language guidance throughout the process.

What makes the service particularly practical is that legal and accounting assistance sits within the same firm. Once incorporation has been completed, clients can continue with bookkeeping, taxation, payroll, VAT matters, corporate changes, contracts, and other ongoing requirements instead of finding separate providers for each function. This creates useful continuity for foreign owners who would rather keep their Bulgarian compliance and corporate matters coordinated through one professional team.

There is also a notably personal element at the beginning of the relationship. New clients have direct involvement from the firm's founder and managing director during the early setup stage before individual matters move to the relevant team members. Combined with its foreign-founder focus and integrated legal-accounting structure, this makes Profirms an especially natural choice for entrepreneurs who want close guidance during incorporation and dependable professional support once the business begins operating.

3. Kambourov & Partners

Corporate Law Support for More Complex Business Structures

Kambourov & Partners approaches company establishment primarily from the perspective of a full-service business law firm. Founded in 1988, it advises domestic and international corporate clients across areas including corporate and M&A, banking and finance, employment, competition, intellectual property, real estate, tax, and dispute resolution.

Its corporate practice covers the business lifecycle from incorporation and initial structuring through governance, capitalization, reorganizations, acquisitions, and other significant corporate changes. For foreign investors considering subsidiaries, joint ventures, reorganizations, or more sophisticated ownership arrangements, that depth of corporate-law experience may be especially relevant.

The firm also advises on shareholder relations, board procedures, contracts, capital increases, regulatory approvals, and continuing corporate compliance. This means its value is not limited to establishing the legal entity itself. Companies expecting substantial transactions or regulatory work later can maintain a legal relationship that continues as their Bulgarian activities become more complex.

Kambourov & Partners is consequently more naturally suited to organizations that see incorporation as part of a broader investment or corporate project. A founder primarily seeking a combined formation, bookkeeping, and routine accounting package may approach the market differently, while companies with significant legal structuring or transactional needs may appreciate the firm's corporate emphasis.

4. Leinonen Bulgaria

Full-Cycle Outsourcing for International Businesses

Leinonen Bulgaria combines company registration with accounting, payroll, taxation, legal assistance, and management reporting. The broader Leinonen Group has extensive experience working with cross-border businesses, while its Bulgarian operation specifically positions its services toward foreign-owned companies that need help adapting to local rules and business practices.

During the establishment phase, Leinonen can help founders consider the appropriate legal structure, prepare for registration, open a bank account, and complete company registration procedures. Its legal services also cover company and tax registrations, contracts, interaction with authorities, and other practical matters associated with operating a foreign-owned business.

Its full-cycle model becomes particularly relevant after the company has started trading. Leinonen provides continuing accounting, payroll, taxation, and reporting support, allowing foreign management teams to outsource recurring Bulgarian administrative functions to a local provider. It can also support businesses through later growth, restructuring, or liquidation.

Leinonen may therefore be particularly attractive to international companies that are comfortable with an outsourcing-oriented relationship. Its combination of local Bulgarian expertise and a wider international organization makes it a useful option for companies that expect accounting and payroll to become significant components of their ongoing requirements.

5. Company Bulgaria

Straightforward Incorporation With Banking and Accounting Options

Company Bulgaria operates as a specialized company registration service aimed in part at foreign entrepreneurs. Its offering emphasizes the possibility of establishing a Bulgarian company without the founder necessarily travelling to Bulgaria, which can make it relevant to international owners seeking a relatively direct incorporation process.

Its formation services cover the practical steps involved in creating a Bulgarian business entity, while related assistance is available for corporate banking. The company presents registration, banking, and accounting as connected services, giving clients the option to obtain several of the practical components required for operating a newly established company through the same provider.

Accounting is offered through a related professional-services operation and can include bookkeeping, payroll, and tax support. That allows clients who begin with incorporation to continue into recurring administrative services rather than ending the relationship immediately after registration.

The model is easy to understand and likely to appeal to founders who want clearly defined company setup assistance followed by standard business administration. It has a more specialized incorporation and accounting character than firms centered on sophisticated corporate transactions, which may suit small and medium-sized foreign-owned businesses looking for a practical route into Bulgaria.

6. Accace Bulgaria

International Corporate Services With Scalable Outsourcing

Accace Bulgaria provides corporate and secretarial services as part of a wider portfolio covering accounting, payroll, HR, taxation, transactions, and legal advisory. Its Bulgarian team supports businesses entering the market as well as existing companies that want to outsource substantial parts of their local administration.

For market entry, Accace can assist with establishing and registering legal entities, tax registrations, bank account arrangements, permits, licenses, and registered-address services. It also provides advice on operational structures and local compliance, which can be valuable to international companies assessing how a Bulgarian subsidiary should function before registration takes place.

The relationship can continue through statutory record keeping, accounting, payroll, taxation, corporate changes, communication with authorities, and eventual liquidation if required. This breadth gives Accace a distinctly outsourced corporate-services profile rather than positioning incorporation as an isolated product.

Its international network and experience with companies of varying sizes can make Accace especially relevant to established organizations entering Bulgaria. Smaller entrepreneurs can also use its services, although companies expecting more extensive HR, payroll, compliance, and back-office requirements are particularly well aligned with its offering.

7. Ruskov Law

Law-Led Assistance With Bulgarian Company Formation

Ruskov Law provides corporate and commercial legal assistance to businesses operating in Bulgaria, including guidance connected with the establishment of limited liability companies. A legal-led approach can be useful for foreign founders who want to understand not only the filing process but also the ownership, management, and governance rules applying to the entity they create.

Its published guidance covers Bulgarian OOD and EOOD structures and the requirements involved in incorporating them, including constituent documents, capitalization, appointment of management, and registration in the Commercial Register. These are important considerations for founders who have little previous familiarity with Bulgarian company law.

A law firm can also remain useful after incorporation when questions arise around contracts, employment, corporate changes, shareholder arrangements, or relationships with Bulgarian authorities. For businesses with legal considerations extending beyond basic registration, continuity with advisers already familiar with the ownership structure can simplify future matters.

Ruskov Law therefore represents a more traditional legal-services route into company formation. It may appeal particularly to founders who place corporate-law advice at the center of the setup process and are comfortable organizing bookkeeping or other operational functions according to their separate business needs.

8. Eurofast Bulgaria

Cross-Border Formation and Compliance Expertise

Eurofast Bulgaria combines company registration with tax, accounting, corporate, payroll, and advisory services. The organization has operated in Sofia since 1998 and places substantial emphasis on cross-border business, making it relevant to international companies establishing Bulgarian operations within a wider regional structure.

Its company registration capabilities cover different forms of entities and overseas-company structures. Eurofast can also provide corporate and trustee services, international banking assistance, global mobility support, and other advisory services associated with entering or expanding within a foreign market.

After formation, clients can draw on accounting and compliance, tax and legal, payroll, and corporate advisory teams. This can be particularly useful for international organizations that need Bulgarian reporting to work alongside policies or reporting structures maintained elsewhere in their group.

Eurofast consequently stands out more for regional and cross-border professional services than for a narrowly packaged incorporation experience. Businesses expecting tax structuring, international reporting, payroll, or expansion across several jurisdictions may find that broader orientation particularly useful.

9. Bulgarian Companies Limited

Specialist Formation Services for International Entrepreneurs

Bulgarian Companies Limited has developed a specialist service around helping international clients establish Bulgarian legal entities. Its stated formation experience includes EOOD and OOD companies, branches, trade representative offices, joint stock companies, holding structures, foundations, and ready-made companies.

The firm's formation offering combines corporate lawyers and accounting professionals and includes support with areas such as company naming, registered-office arrangements, and bank-account assistance. Bilingual incorporation documentation is also available in several languages, which can make the paperwork easier to understand for founders who do not speak Bulgarian.

Clients requiring support after registration can also use separate accounting, payroll, and VAT services. The distinction between incorporation and ongoing accounting allows founders to select additional assistance according to how active or administratively complex their new Bulgarian company becomes.

This makes Bulgarian Companies Limited a practical specialist option for entrepreneurs who are principally focused on forming a Bulgarian entity and then adding accounting or payroll as required. Its dedicated formation orientation is particularly relevant to foreigners who want a provider accustomed to handling international clients from the outset.

10. Sb Accounting & Consulting

Business Outsourcing Built Around Accounting and Administration

Sb Accounting & Consulting is an established Bulgarian outsourcing provider whose main strengths lie in accounting, payroll, HR administration, financial management, and related compliance functions. The business has operated for more than three decades and works with both Bulgarian and international companies.

Company registration forms part of a broader set of corporate and administrative capabilities rather than standing alone as the firm's principal product. Its legal services can support companies at different stages of development, while its accounting operation deals with statutory reporting, tax compliance, VAT, and end-to-end financial processes.

The firm's technology and outsourcing orientation becomes more noticeable once a business is operational. Sb works with multiple financial systems and provides payroll administration, HR services, VAT reporting, fiscal representation, and other recurring functions that can become increasingly important as a Bulgarian subsidiary hires employees and grows.

Sb may therefore be particularly relevant to established international businesses that require a substantial local outsourcing partner after market entry. A small founder looking only for company incorporation may require a narrower service, while organizations expecting meaningful accounting, HR, and payroll volumes can make greater use of Sb's broader infrastructure.

11. Rödl & Partner

Interdisciplinary Support for International Market Entry

Rödl & Partner provides professional services in Bulgaria through an international network combining legal, tax, business, and related advisory expertise. Its approach is strongly geared toward businesses operating across borders and companies that want local Bulgarian advice delivered within a broader international professional-services framework.

For foreign investors, this interdisciplinary model can be useful during establishment because legal structure, taxation, employment, and financial administration frequently overlap. The organization is particularly suited to situations in which a Bulgarian entity forms one part of a wider international group rather than operating entirely independently.

After incorporation, companies can continue using multidisciplinary assistance for local compliance and broader business matters. This continuity may be valuable where Bulgarian decisions must be coordinated with parent-company requirements, international reporting, or cross-border transactions.

Rödl & Partner consequently occupies a different position from smaller formation specialists. Its strengths are especially relevant to internationally organized businesses that prefer an established professional network and want legal and tax considerations integrated into broader commercial planning.

12. SofiaTax

Accounting and Tax Support for Small International Businesses

SofiaTax focuses primarily on accounting, taxation, VAT, and payroll for freelancers, foreign professionals, and smaller service businesses operating in Bulgaria. The firm emphasizes English-language communication and practical explanations, which can be helpful for international owners who are unfamiliar with the country's recurring accounting obligations.

Its service model is less centered on complex corporate formation than some of the dedicated company-registration providers in this comparison. Instead, its strongest role begins around the financial and tax setup of a business, including VAT questions, bookkeeping processes, invoicing, and the tax implications of operating through a Bulgarian company.

Ongoing accounting can include processing invoices and bank records, VAT reporting, annual tax returns, financial statements, and payroll. SofiaTax also works with internationally active businesses and professionals invoicing customers in Bulgaria, elsewhere in the EU, the United Kingdom, the United States, and other markets.

For that reason, SofiaTax is particularly relevant when the founder's priority is straightforward ongoing accounting and tax administration for a relatively lean business. Entrepreneurs requiring extensive corporate-law structuring may look for additional legal assistance, while consultants, freelancers, and owner-managed companies may appreciate the firm's focused accounting approach.

13. Grant Thornton Bulgaria

Tax and Outsourcing Strength for Established Businesses

Grant Thornton Bulgaria provides tax, accounting, payroll, financial reporting, and wider professional advisory services. Its offering is particularly substantial on the continuing financial-compliance side of operating a business, making it relevant to companies that require sophisticated support after establishing a Bulgarian presence.

Rather than presenting itself mainly as a packaged company-formation provider, Grant Thornton approaches market entry through the broader requirements of corporate finance, taxation, compliance, and professional advisory. International organizations considering a Bulgarian subsidiary may therefore use the firm where incorporation forms part of a larger tax or business-planning exercise.

Its outsourcing capabilities include statutory bookkeeping, management reporting, financial statements, payroll, VAT compliance, corporate income tax, and transfer pricing. These services become increasingly valuable for companies with larger transaction volumes, employees, international related-party dealings, or group-reporting requirements.

Grant Thornton is consequently most compelling for organizations that expect a considerable compliance and reporting workload rather than founders searching solely for a simple registration package. Its international professional-services environment can be particularly useful to established businesses that already work with audit, tax, or advisory firms in other countries.

14. Kreston Bulgaria

Accounting-Led Support With International Network Connections

Kreston Bulgaria, represented prominently through Kreston BulMar, has a broad accounting and consulting profile that includes accounting, payroll, tax consultancy, financial audit, legal services, corporate finance, and related business support. The firm is connected to the wider Kreston international network, which gives it a useful international dimension for foreign-owned companies.

Company formation can sit alongside these wider professional services, making Kreston relevant to businesses that want establishment support connected to longer-term accounting and financial administration. Its nationwide Bulgarian presence can also be useful to companies whose activities are not concentrated exclusively in central Sofia.

Once trading begins, the firm's accounting, payroll, taxation, reporting, and advisory capabilities become central to the relationship. Businesses requiring regular statutory accounting or financial oversight can therefore continue working with the same broader professional network instead of viewing incorporation as the end of the engagement.

Kreston Bulgaria is likely to appeal most to businesses that value a recognizable international accounting network combined with extensive local accounting resources. Its profile is particularly strong for ongoing financial administration, while entrepreneurs who prioritize highly personalized legal and accounting coordination from the first incorporation conversation may prefer a more tightly integrated formation-focused model.

Choosing Support That Continues Beyond Registration

Company formation is only the first administrative milestone in establishing a sustainable Bulgarian business. Foreign founders should consider not only who can prepare the incorporation documents, but also who can assist with taxation, VAT, bookkeeping, payroll, corporate changes, and legal questions once the company begins operating. The providers above serve different types of businesses, from individual entrepreneurs to multinational groups, but Profirms offers the most naturally integrated proposition for foreign founders who want personal guidance, legal and accounting expertise in one place, and continuity from initial setup into everyday business compliance.
