The Outbound Remittance Wall: How Vietnamese Tech Studios Secure Global SaaS Revenues via HK Entities

Vietnam has become a powerhouse in global tech. From fast-growing SaaS startups to elite hardware engineering studios, Vietnamese talent is building products used worldwide.

But there’s a problem. While the engineering happens in Ho Chi Minh City and Hanoi, commercializing those products globally creates a massive logistical headache: getting paid.

For Vietnamese tech founders, scaling globally means dealing in multiple currencies — receiving subscription revenue in USD, EUR, or GBP, and paying for international servers, global marketing, and foreign contractors.

Doing this through a locally incorporated Vietnamese entity traps founders in a rigid foreign exchange system. To bypass these restrictive forex controls, smart Vietnamese tech studios are setting up Hong Kong corporate entities as their global billing and financial hubs.

The Problem: Vietnam’s Strict Foreign Exchange Controls

Vietnam’s State Bank (SBV) heavily monitors foreign capital flows. All buying, selling, lending, and transferring of foreign currency must be conducted through credit institutions or other financial institutions authorised by the State Bank of Vietnam (SBV). Furthermore, all monetary transactions within Vietnam must be conducted in Vietnamese dong (VND).

When a Vietnamese SaaS company receives foreign subscription revenue, those funds must be routed through authorized banks and are subject to strict conversion rules. Bringing money into Vietnam is relatively straightforward.

The real trap appears when tech studios need to send money back out.

Outflows of foreign currency are strictly authorized only for specific transactions: payments for imports, services abroad, repayment of foreign loans, and the transfer of profits and dividends.

If a Vietnamese studio needs to quickly pay AWS, run global ad campaigns, or compensate freelance developers overseas, every single outbound transfer requires justification to local banks. The administrative burden is agonizingly slow. For a fast-moving tech startup, that lack of financial agility can be crippling.

The Solution: The Hong Kong Billing Hub

To escape the VND conversion trap, Vietnamese founders are increasingly incorporating proxy entities in Hong Kong. By routing global sales and international expenses through a Hong Kong company, the Vietnamese studio retains its local engineering base while effectively “offshoring” its treasury and global billing operations.

Hong Kong is a common-law jurisdiction with a freely convertible currency and absolutely no foreign-exchange controls. Tech studios operating through a Hong Kong entity can move money in and out freely, without justifying every outbound transfer to a central bank.

There are no foreign exchange controls — you can move money in and out of Hong Kong freely.

Hong Kong business bank accounts naturally support multi-currency holding. A Vietnamese founder can collect global SaaS revenues in USD, hold those funds in USD, and pay international vendors directly in USD. This eliminates the friction, delays, and currency conversion losses associated with bringing money into Vietnam only to send it back out.

Seamless Remote Setup for Foreign Founders

For Vietnamese engineers, establishing this financial hub does not require relocating or abandoning local operations.

Under the Companies Ordinance, there is no nationality or residency restriction — a Vietnamese citizen can own 100% of the shares and act as the sole director without needing a local visa.

The entire incorporation process can be completed completely remotely via Hong Kong’s e-Registry. While the law does mandate a Hong Kong-resident company secretary and a local registered office address, Vietnamese founders simply outsource these requirements to professional corporate service providers.

Tax Efficiency and the Territorial System

Beyond bypassing forex controls, the Hong Kong hub offers significant tax advantages. Hong Kong operates on a territorial source principle — only profits arising in or derived from Hong Kong are subject to profits tax.

For a Vietnamese tech studio whose actual product development and core operations take place outside of Hong Kong, offshore profits generated from international SaaS sales may potentially be exempt from Hong Kong profits tax entirely, provided the activities are properly structured.

Even if profits are deemed onshore, Hong Kong offers a highly competitive two-tier tax rate: 8.25% on the first HK$2 million of assessable profits and 16.5% thereafter. There is no capital gains tax and no withholding tax on dividends distributed back to the founders.

Scaling Without Limits

For Vietnamese software studios and hardware teams, the quality of their products is already world-class. However, relying solely on a local corporate entity to manage global revenue leaves them vulnerable to currency conversion losses and regulatory bottlenecks.

By establishing a Hong Kong operational proxy, Vietnamese tech founders can secure their global revenues, process multi-currency billing seamlessly, and scale their global operations with the financial agility that modern SaaS businesses demand.
