• Airwallex: Global fintech platform, provides multi-currency accounts, payment settlement, friendly to cross-border business.
• Mercury: US digital bank, designed for startups, friendly to non-US residents registering US companies.

2. Overseas Company Registration: Why Necessary and How to Choose a Jurisdiction

Most mainstream overseas payment platforms require applicants to have a legitimate overseas corporate entity and a corresponding overseas bank account. Applying in a company name typically has fewer restrictions and easier approval than personal accounts. Choosing the right jurisdiction is crucial, affecting cost, taxation, subsequent maintenance, and most importantly, the difficulty of opening a bank account.

Comparison of Pros and Cons of Mainstream Jurisdictions:

Feature	US (Delaware)	US (Wyoming)	Hong Kong	Singapore
Company Type	C-Corp (suitable for fundraising/IPO), LLC (not ideal for fundraising)	LLC (first state to support LLCs), C-Corp	Limited Company	Private Limited Company
Advantages	Well-established corporate legal system, broad legal support, ideal for fundraising/IPOs; #1 state for incorporations in the US.	Tax advantages, no state corporate income tax, low annual fees; strong privacy protection; low cost, simple maintenance.	Open economy, low tax rate (profits tax), relaxed management; friendly to mainland Chinese background, fast registration; convenient international capital flow.	Political and economic stability, tax incentives, many double taxation treaties; developed financial system; digitalized registration process, suitable for tech companies.
Disadvantages	Higher registration/maintenance costs; complexity in remotely opening US major bank accounts.	Legal framework less mature than Delaware's; not ideal for equity financing; remote account opening also faces challenges.	Some payment platforms have strict reviews for HK companies; policies for digital businesses are changing; bank account opening difficulty remains high.	Costs slightly higher than HK; strict regulation for certain high-risk industries; bank account opening review is strict but relatively more friendly than HK.
Taxation	No state corporate income tax (if no physical operations); federal filing required; C-Corp dividends subject to double taxation for shareholders.	No state corporate income tax, low annual fees; strong privacy protection, similar to Nevada in not exchanging tax data with IRS for certain entity types.	Corporate tax rate 16.5%, only taxes profits sourced in Hong Kong.	Corporate tax rate 17%; supports compliant offshore operations.
Registration Cost	High (~$500-$2000 or more)	Low (~a few hundred USD)	Low (~HKD 1700-3000)	Medium (~SGD 300-1500)
Registration Time	7-20 business days	Fast, depends on agent/service provider	1-3 days	7-10 business days
Typical Use Case	Large SaaS/E-commerce companies with IPO/fundraising plans.	Startups/SMEs/individual developers; those seeking low-cost, high-privacy solutions.	Suitable for APAC market, cross-border trade, friendly to mainland Chinese background, but bank account opening is a major bottleneck.	Suitable for long-term operations, fintech, Asian headquarters; bank account opening is relatively more friendly than HK.

Selection Summary: The most common choices for Chinese developers going global are a Wyoming LLC (low cost, simple maintenance, good privacy) or a Delaware C-Corp (suitable for fundraising, IPO). Registration itself is relatively easy for both, but the subsequent bank account opening is the key challenge. Hong Kong registration is fast and low-cost, but bank account opening is extremely difficult and maintenance carries high risk. Singapore is suitable for companies with long-term Asian plans and a higher budget; bank account opening is relatively more friendly and has a higher success rate than in Hong Kong.

3. Core Step: Opening an Overseas Bank Account (Critical Focus)

For non-residents (especially developers based in China), opening an overseas corporate bank account is often the most challenging part of the entire global expansion process. Traditional banks have high requirements, while digital banks offer new solutions.

3.1 Why is an Overseas Bank Account So Important and Difficult?

1. Payment Platform Requirements: Most mainstream payment platforms (e.g., Stripe, Adyen) require the linked receiving account to be a bank account in the company's name, located in a specific country/region (usually the company's place of incorporation or primary business location).
2. Funds Settlement: Payments collected by the platform need to be settled into the company's bank account for subsequent operational expenses, employee salaries, supplier payments, or profit distribution.
3. Compliance: Opening a bank account in the company's name better demonstrates the business's legitimacy and authenticity, meeting the Anti-Money Laundering (AML) and Know Your Customer (KYC)/Know Your Business (KYB) requirements of payment platforms and financial institutions.
4. Traditional Bank Barriers: Traditional banks in the US, Hong Kong, Singapore, etc., have very strict requirements for opening accounts for non-residents/companies without local physical operations, often requiring:
   • SSN or ITIN (US): Most traditional US banks require a US Taxpayer Identification Number for personal and business accounts.
   • Local Residential Address & Phone: Banks need to verify the applicant's permanent address and contact information.
   • In-Person Visit: Many traditional banks require company principals or authorized signatories to visit a branch in person for identity verification and account opening procedures. This is costly and inconvenient for developers based in China.
   • Detailed Business Proof: Requires extensive documentation like supplier/customer contracts, invoices, shipping documents, articles of incorporation, ownership structure to prove the business's authenticity and rationale.
   • Minimum Deposit & Maintenance Fees: Typically involve high minimum opening deposits and monthly maintenance fees.

3.2 Digital Banks/Fintech Companies: A New Option for Non-Residents

The rise of digital banks and fintech platforms in recent years offers non-residents a path to open accounts without in-person visits, with a simplified process. They typically don't require an SSN, verifying identity and company credentials online.

Feature	Mercury	Wise Business (formerly TransferWise)	Airwallex	Brex	Stripe Treasury	Traditional Banks (e.g., East West Bank, US Major Banks)
Target Client	Primarily serves US-registered companies (DE/WY LLC/C-Corp)	Serves companies registered in multiple jurisdictions (US/SG/HK/EU, etc.)	Serves companies registered in multiple jurisdictions (US/SG/HK/EU, etc.)	Primarily serves US companies with substantial US operations	Serves US-registered companies within the Stripe ecosystem	Serves local residents/enterprises; high barriers for non-residents
Non-Resident Friendliness	High, fully remote, no SSN required	High, fully remote	High, fully remote	Medium-Low, high requirements for US entity and operations	Medium-Low, depends on Stripe account and US entity	Very Low, most require in-person visits, SSN/local address
Application Process	Online application, submit company docs, passport, typically 3-5 days	Online application, submit company docs, passport/ID, typically completed within days	Online application, submit company docs, passport, typically completed within days	Online application, complex materials, strict review, longer timeline	Apply within Stripe Dashboard	Usually requires appointment, in-person branch visit, extensive materials, review takes weeks to months

Key Recommendations:

• For US-registered companies (DE/WY LLC/C-Corp): Prioritize Mercury. It's currently the most friendly and convenient banking option for non-US residents with US-registered companies, supporting fully remote account opening without requiring an SSN or a physical US address (a virtual mailing address provided by a registered agent is acceptable).
• For Singapore or Hong Kong registered companies: Wise Business and Airwallex are good digital account choices. They support account opening for companies registered in multiple jurisdictions, have online processes, and offer transparent fees, making them suitable for cross-border payments and receipts.
  • Singapore: Compared to Hong Kong, traditional banks in Singapore (e.g., DBS, OCBC, UOB) are relatively more friendly to non-resident companies, with higher success rates. Some support video verification, but detailed business documents are still required. If budget and long-term planning allow, attempting a local bank is a viable path.
  • Hong Kong: Opening an account with a traditional bank is extremely difficult, highly uncertain, and carries the risk of account closure without warning. Unless you have very strong proof of genuine business and professional agency services, it's not recommended as the primary option. Digital accounts or considering registration in other regions are more reliable solutions.
• East West Bank: The traditional accounts at East West Bank have high requirements for remote opening by non-residents (e.g., SSN, US address), making it very difficult. Its Velo Global Checking Account supports remote opening for personal accounts for specific identities (e.g., Mainland China, Hong Kong, Macau, Taiwan residents), but it has a minimum deposit requirement ($2500), a monthly fee ($25), and is a personal account, making it unsuitable for binding to platforms like Stripe as a company payment account. Therefore, East West Bank is not generally the first choice for non-resident businesses to remotely open commercial accounts.
• Brex: Powerful features, but has very high requirements for US business entities (needs proof of real US office address, employees, customers, revenue streams, etc.). It's not suitable for developers who have only registered a US company but whose main operations and personnel are in China. It's suitable for businesses that already have a certain scale of operations in the US.
• Stripe Treasury: Tightly integrated with Stripe, but the account opening requirements are also high, requiring an active Stripe account and meeting certain qualifications. It's not an entry-level option.

3.3 Specific Steps and Pitfalls to Avoid When Opening an Overseas Bank Account

Operational Process (Using Mercury application as an example; processes for other digital or traditional banks are similar but requirements differ):

1. Complete overseas company registration: Ensure the company is legally registered and obtain documents such as the registration certificate, Articles of Organization/Incorporation, etc.
2. Obtain an EIN: For US companies, you must obtain an EIN (Employer Identification Number) issued by the IRS. Non-residents without an SSN need to apply by fax or mail using Form SS-4, which takes a long time (2-4 weeks, or even longer). It is recommended to apply early or seek assistance from an agent.
3. Prepare company documents: Business license, company bylaws (Operating Agreement for LLCs), proof of equity/shareholding, register of directors/shareholders, etc.
4. Prepare identity documents for the legal representative/beneficial owner: Passport (valid, with clear photo page and signature page), ID card, etc.
5. Prepare proof of address: Company registered address, mailing address (virtual addresses are acceptable for US companies). Some banks may require proof of the legal representative's residential address.
6. Choose a bank/platform: Select a suitable bank or digital account (e.g., Mercury, Wise Business, Airwallex) based on the company's registration location, business model, budget, and need for remote account opening.
7. Submit the application online: Go to the official website of the target bank or platform, find the business account opening section, fill out the application form, and upload the required documents.
8. Video verification/interview: Complete an online video identity verification as required. Traditional banks usually require an in-person visit.
9. Business model explanation: Some banks will inquire about the company's business model, sources/uses of funds, expected transaction volume, etc. Provide a clear explanation.
10. Wait for review: After submission, wait for the bank's review. Digital banks are typically faster; traditional banks are slower.
11. Deposit initial funds: Upon approval, deposit the minimum opening amount as required (digital banks often have no or very low requirements; traditional banks have higher requirements).
12. Activate the account: Receive the debit card, online banking information, etc., and activate the account to start using it.

Common "Pitfalls" and Precautions:

• False/Incomplete documents: Submitting any false information or omitting key documents will lead to application failure or even being blacklisted. All documents must be authentic, clear, and valid.
• Unable to obtain an EIN: US companies without an EIN cannot open a commercial bank account. Ensure you apply in advance and wait patiently.
• Changing bank policies: Policies for non-resident account opening may change at any time. Before applying, be sure to check the bank's official website or consult customer service for the latest information.
• Unacceptable business model: Some banks reject high-risk industries (e.g., gambling, cryptocurrency, adult content, restricted goods sales) or business models that cannot prove authenticity. Ensure your business is legal and compliant, and you can provide valid business proof (e.g., website, product introduction, contracts).
• Lack of US entity support (for Brex/some traditional banks): It is difficult to pass the strict review of demanding banks with only a "shell company" and no signs of actual operations (e.g., US employees, lease contracts, significant transaction volume with local US customers).
• Failure to provide a reasonable explanation for fund sources/uses: Large or frequent fund transactions require a reasonable explanation; otherwise, they may trigger the bank's risk controls.
• Using unreliable agents: Agents can assist with the process but cannot guarantee 100% success. Choosing a poor agent may lead to risks like data leakage or account issues due to using false information. Core documents (company files, identity proofs) must be kept and verified by yourself. Bank account information is especially important; never completely hand over control of online banking to an agent.

Tips to Avoid Pitfalls:

• Thorough research: Research the impact of different registration jurisdictions on bank account opening and the policies of various banks/platforms before registering the company.
• Choose platforms friendly to non-residents: Prioritize digital accounts like Mercury, Wise Business, Airwallex that explicitly support remote account opening for non-residents.
• Apply for an EIN early: For US companies, start the EIN application process as early as possible.
• Prepare detailed materials: Organize all company and personal documents in advance, along with materials that can prove the authenticity of the business.
• Maintain information consistency: Ensure company name, address, contact information, and legal representative/shareholder details are consistent across all documents and applications.
• Clearly explain the business: Prepare a concise and clear English business introduction.
• Be patient: Bank reviews take time, especially for traditional banks.
• Seek professional advice: If you have questions about the process or documents, consult a registration agent or professional advisor.

3.4 Integrating Payment Gateways and Going Live to Receive Payments

1. Complete bank account binding: In the payment platform's settings, bind the newly opened overseas company bank account as the payout account.
2. Configure payment methods: Based on business needs and target markets, configure credit cards, e-wallets (PayPal, Apple Pay, Google Pay), and local payment methods (e.g., SEPA Direct Debit, ACH).
3. Integrate API/SDK: Integrate the payment gateway into your own website or application according to the technical documentation provided by the payment platform. Perform sandbox environment testing.
4. Conduct small real transaction tests: Perform small real transaction tests in the production environment to verify that payment processing, fund receipt, refunds, and other functions work correctly.
5. Go live: After successful testing, officially launch the payment service.

4. Summary and Decision Path

For Chinese developers expanding overseas, the core path to accessing overseas payments is typically: Register an overseas company → Open an overseas company bank account → Apply for a payment platform account and bind the bank account → Integrate payments. Among these, opening an overseas bank account is the most difficult and critical step in the process.

• Payment platform selection path:
  • If your main business is SaaS or digital products, you prioritize ultimate convenience, do not want to handle tax compliance, and can accept higher fees, Paddle (MoR) is the first choice.
  • If you prioritize flexible control, want lower fees, are willing to handle tax and compliance yourself, require developer-friendliness, and can solve the bank account issue, Stripe or Braintree are mainstream choices.
  • If your business is large-scale, highly globalized, and has complex payment method needs, Adyen is a more suitable platform.
  • If your main need is batch cross-border transfers (e.g., paying suppliers, remote employee salaries) or receiving payments in specific currencies, Wise Business is a cost-effective option.
  • If your core business is on e-commerce platforms like Amazon, Payoneer provides convenient payment collection integration.
  • If your business involves global multi-currency receipts and payments, Airwallex is a reliable fintech partner.
• Company registration and bank account opening path:
  • Startups/SMEs or individual developers seeking low cost and privacy protection, primarily targeting the US market: Prioritize registering a Wyoming LLC in the US, paired with opening a Mercury digital bank account. This is currently the most friendly and feasible comprehensive path for non-residents.
  • Have clear financing/IPO plans, or the business entity is in Europe/America: Prioritize registering a Delaware C-Corp in the US, and also prioritize trying to open a Mercury bank account.
  • Business mainly targets Asia, or you want a fast registration process but can accept the challenge of bank account opening: Consider registering a Hong Kong company. Bank account opening is difficult, requiring substantial proof of real business activity, or consider pairing with a Wise Business/Airwallex digital account.
  • Have long-term Asian development plans, value brand image and financial services, and have a certain budget: Consider registering a Singapore company. Bank account opening is relatively more friendly than in Hong Kong; you can try local traditional banks or pair with Wise Business/Airwallex.

5. Additional Suggestions and Continuous Optimization

• Tax Handling and Planning: Cross-border income involves corporate income tax in the company's country of registration and sales tax/VAT in the countries where business occurs. It is essential to consult a professional cross-border tax accountant for proper tax planning to avoid risks from double taxation or tax evasion. Different company structures (e.g., US C-Corp vs. LLC) have significant differences in tax treatment. Using a Merchant of Record (MoR) platform can greatly simplify sales tax handling.
• Fund Repatriation Path: Plan in advance how to legally and efficiently transfer overseas funds back to your home country. This may involve various methods, such as dividends from the overseas company to domestic individuals or companies, or payment of service fees, each with its own compliance requirements and tax costs. Understand the foreign exchange management policies of your country.
• Ongoing Compliance and Annual Reviews: Overseas companies need to file annual returns and perform maintenance (annual reviews, tax filings, etc.) on time. Failure to meet obligations on time may lead to company deregistration, which in turn can affect the normal use of bank accounts and payment accounts. Bank accounts themselves also have activity and compliance requirements; avoid letting them become "dormant accounts" or being used for illegal transactions.
• Monitor Policy Changes: Global financial regulations, tax policies, and the terms of service for payment platforms and banks are constantly changing. Regularly follow relevant news and official announcements to ensure your business always complies with the latest requirements.
• Multi-Currency Management: Depending on the target market, you may need to handle multiple currencies. Choose payment platforms/banks that support multi-currency accounts and settlements (e.g., Wise Business, Airwallex, Mercury) and consider exchange rate fluctuation risks.
• User Payment Habits: Gain a deep understanding of the payment preferences of users in your target market (credit cards, local bank transfers, e-wallets, BNPL, etc.). Choose a platform that covers these mainstream methods, or use a combination of multiple platforms to improve payment success rates.
• Contingency Plans: Considering the risk of overseas account freezes, if your business scale allows, consider opening an additional bank account or using a different payment platform as a potential backup solution.

Choosing an overseas payment solution is a complex process involving company structure, tax planning, legal compliance, bank account opening, and technical integration. Thorough research, careful decision-making, and seeking professional help when necessary are key to ensuring smooth revenue collection and steady, long-term development for your overseas business. Especially for the bank account opening stage, sufficient time and effort should be invested in research and preparation.
