Accounting Outsourcing and Consultations

Small and mid-size businesses in Japan of international corporations rarely have the luxury of having extensive in-house financial functions. This can be particularly difficult as they look for in-house accountants who have expertise in IFRS and/or US GAAP with the right Business English proficiency.
VentureINQ maintains a practice dedicated to the specific needs of small and mid-size businesses, including international organizations. We offer a range of services tailored to a company’s specific life cycle point.

Tax Compliance and preparation

At VentureINQ, we pride ourselves on our proven ability to help our clients develop optimal financial and business strategies, anticipate problems and seize opportunities. At the same time, we provide experienced and timely guidance on tax compliance and preparation.

Corporate Tax Outsourcing

The task of tax compliance places demands on a business’ finance function. This is even more the case when the organization has undergone a major transaction or is adopting a new tax strategy. Effective tax compliance then becomes dependent on human resource issues of hiring, training, and managing full-time accounting employees with the right capabilities.

VentureINQ’s Corporate Tax Outsourcing service allows companies to avoid this problem by relying upon our highly trained staff. Partnering with us during peak tax season allows businesses to retain control of their internal tax function while getting the extra bandwidth they need to meet deadlines, avoid employee burnout and maintain flexibility over the allocation of in-house resources.

Business Advisory

Japan Business Setup(Doing business in Japan)

Deciding to invest in or expand your company’s presence outside of your country can be overwhelming. VentureINQ is here to offer the expertise necessary to make your decision the right one. Our Japan business setup service was created in response to the increased demand for high quality international consulting services for both inbound and outbound Japan-related investment.

Along with expertise in Japanese tax law and accounting standard, our team offers specialties in feasibility study, Japan entry strategy, business planing, incorporation support,  investment banking and transactional advisory services.

GAAP Consultation(IFRS and USGAAP)

In a world that is becoming flatter by the day, there is general agreement that the adoption of global accounting standards is inevitable—and is a necessary development.

While the timetable and specifics of the implementation of International Financial Reporting Standards (IFRS) in the United States and Japan have yet to be finalized, many companies are using the time to thoroughly prepare for the transition. VentureINQ’s USGAAP and IFRS specialists help companies develop IFRS transition plans from USGAAP or Japan GAAP based financial statement. We will propose plans customized to the capabilities of their accounting functions, their particular accounting methodologies, and the trajectories of their businesses.

Transactional Advisory

Our full range of service include due diligence, acquisition integration, and other transaction advisory services.

Valuation Advisory

Valuations are critical for a range of business transactions as well as compliance requirements. Accurate valuation requires an understanding of the strategic context at hand and expertise in the technical application of valuation methods.
We provide international clients with valuation services. Our expertise includes covering business enterprises, intangible assets, common and preferred stock.


Agreed Upon Procedures (AUPS)

There are times when you need something other than an audit, compilation or review. When specific tests and procedures are required alongside reports on the results, we are here to help. Agreed upon procedures might include special reviews of bank accounts or internal control systems. Unique to agreed upon procedures is that you have to draw your own conclusions on the results of the tests to measure effectiveness.

At VentureINQ, we have the talent to customize a plan that is right for you.

Control review

Ineffective control system can significantly affect employee’s moral and motivation as well as the control environment of your affiliate corporations. VentureINQ conducts comprehensive controls reviews that give clients the framework to implement strong governance practices within their control environments. Our experienced and credentialed professionals uncover vulnerabilities through industry best-practice methodologies including Control Objectives.

Fraud investigation

Organizations today face the daunting possibility of allegations of wrongdoing from any number of sources—shareholders, anonymous whistleblowers,  employees, customers and suppliers. Often, the board and management must respond rapidly to allegations in order to stem potential financial losses.

VentureINQ assists clients in evaluating allegations of fraud or other wrongdoing involving management, employees or third parties. We combine accounting, investigative, and industry resources to respond rapidly and thoroughly to a variety of allegations.
