A Set of Documents for Foreign Payments
Introduction
Foreign payments are an important part of international business. Companies regularly make overseas payments for imports, services, royalties, loans, investments, software subscriptions, consulting services, and other cross-border transactions.
However, a foreign payment is more than simply instructing a bank to transfer money overseas. Banks, tax authorities, customs authorities, auditors, and accounting teams may require evidence demonstrating why the payment is being made, who is receiving it, what goods or services are involved, and whether the transaction complies with applicable foreign-exchange, tax, customs, and accounting requirements.
A well-prepared foreign payment document package helps a company process payments efficiently, support its accounting records, demonstrate tax compliance, and reduce the risk of payment delays or regulatory questions.
This article provides a practical framework for preparing a set of documents for foreign payments, with particular focus on businesses operating in Vietnam.
1. What Is a Foreign Payment?
A foreign payment is a payment made by a company or individual to a recipient located outside the country, normally through an authorized bank or financial institution.
Common examples include:
Payment for imported goods
Payment for overseas services
Software and SaaS subscriptions
Consulting and professional fees
Management fees
Royalties and license fees
Advertising and marketing services
Interest on foreign loans
Principal repayment of foreign loans
Dividend or profit remittances
Capital contributions to overseas investments
Payment for insurance or transportation services
Reimbursement of expenses
Payments under intercompany agreements
The required documentation depends heavily on the nature and legal basis of the transaction.
2. The Core Principle: Prove the Economic Substance
A strong foreign-payment file should answer five basic questions:
Who?Who is the supplier or recipient?
What?What goods, services, financing, investment, or other transaction is being paid for?
Why?Why does the company have an obligation to make the payment?
How much?How was the amount calculated?
Why is it legally and commercially valid?What contract, invoice, purchase order, customs document, tax document, or other evidence supports the transaction?
The stronger the evidence supporting these questions, the easier it is for the bank, accounting department, tax team, auditor, and management to understand the payment.
3. General Document Package for Foreign Payments
Although requirements vary depending on the transaction, a typical foreign-payment package may contain the following documents:
A. Internal approval documents
Payment request
Payment approval form
Management approval
Purchase requisition
Expense approval
Board or shareholder approval, where applicable
B. Commercial documents
Contract
Purchase order
Quotation
Invoice
Debit note or credit note
Statement of account
Delivery documents
Acceptance documents
C. Banking documents
Bank payment instruction
Foreign currency payment order
Bank transaction confirmation
SWIFT confirmation, where available
Foreign exchange conversion documentation
D. Tax documents
Tax calculation
Foreign contractor tax assessment, where applicable
Withholding tax documentation
Tax payment receipt
Tax exemption or treaty documentation, where applicable
E. Customs documents
For imported goods, the package may include:
Commercial invoice
Packing list
Bill of lading
Air waybill
Import customs declaration
Import permits, where applicable
Certificate of origin
Customs duty payment evidence
F. Accounting documents
Accounting voucher
General ledger entry
Supporting journal entry
Accounts payable reconciliation
Foreign exchange calculation
Exchange-rate evidence
Not every transaction requires every document. The package should be tailored to the underlying transaction.
4. Foreign Payment for Imported Goods
Payments for imported goods are among the most common foreign-payment transactions.
A typical document package may include:
Import purchase contract
Purchase order
Commercial invoice
Packing list
Bill of lading or air waybill
Import customs declaration
Certificate of origin, if relevant
Goods receipt documentation
Import duty documentation
VAT documentation
Payment request
Bank payment instruction
Bank transfer confirmation
For example, suppose a Vietnamese company purchases machinery from a Japanese supplier.
The payment file should ideally establish the complete transaction chain:
Purchase order → Contract → Shipment → Customs clearance → Invoice → Goods receipt → Payment
This creates a clear audit trail between the commercial transaction, accounting records, customs records, and bank payment.
5. Foreign Payment for Services
Foreign service payments can require additional tax analysis because the payment may potentially be subject to withholding or foreign contractor tax depending on the jurisdiction and nature of the service.
Examples include:
Consulting
Software development
IT services
Management services
Technical support
Marketing
Advertising
Training
Engineering
Legal services
Accounting services
Cloud services
A typical document package may include:
Service agreement
Statement of work
Purchase order
Invoice
Timesheet or service report
Deliverables
Acceptance certificate
Email or other evidence of service completion
Tax analysis
Foreign contractor tax documents, where applicable
Payment approval
Bank transfer instruction
Payment confirmation
For service transactions, companies should pay particular attention to demonstrating that the service was actually provided.
An invoice alone may not always provide sufficient evidence of the underlying transaction for accounting, tax, or audit purposes.
6. Contract
The contract is normally one of the most important documents supporting a foreign payment.
A well-drafted contract should clearly identify:
Buyer and seller
Supplier's legal name
Address
Tax identification details, where applicable
Bank account information
Nature of goods or services
Pricing
Currency
Payment terms
Payment schedule
Delivery terms
Responsibilities of each party
Taxes
Governing law
Dispute resolution
Contract duration
For recurring transactions, the contract should also clearly explain the basis for calculating periodic payments.
For example:
Monthly management fee = USD 20,000
The payment file should allow an auditor to trace the USD 20,000 amount back to the contractual terms and supporting evidence.
7. Invoice
The foreign supplier's invoice generally provides the commercial basis for the payment.
Important information includes:
Supplier name
Supplier address
Invoice number
Invoice date
Description of goods/services
Quantity
Unit price
Total amount
Currency
Payment terms
Bank information
The accounting team should reconcile the invoice against the contract and other supporting documents.
For example:
Contract: USD 100,000Invoice: USD 100,000Payment instruction: USD 100,000
If the amounts differ, the difference should be explained and documented.
8. Payment Request
The internal payment request connects the external documents with the company's internal approval process.
A payment request normally includes:
Payee
Amount
Currency
Payment purpose
Contract reference
Invoice reference
Requested payment date
Bank account
Cost center
Accounting account
Tax treatment
Approval signatures
For example:
Payment of USD 50,000 to ABC Consulting Ltd under Service Agreement No. 05/2026 for consulting services provided in August 2026.
This description gives management, accounting, and the bank a clear understanding of the transaction.
9. Tax Documents
Tax considerations are particularly important for foreign payments.
Depending on the transaction, companies may need to consider:
Corporate income tax
VAT
Withholding tax
Foreign contractor tax
Personal income tax
Transfer pricing
Tax treaty provisions
Permanent establishment considerations
For Vietnam-based businesses, payments to foreign contractors may require an assessment of Foreign Contractor Tax (FCT) depending on the nature of the transaction and applicable regulations.
The payment file should therefore contain evidence of the tax analysis and, where applicable:
Tax declaration
Tax payment receipt
Tax calculation
Tax exemption documentation
Tax treaty documents
Certificate of tax residency
Supporting correspondence with tax advisers or authorities
The exact tax treatment should be determined based on the transaction and regulations applicable at the time.
10. Customs Documents for Imported Goods
Where the foreign payment relates to imported goods, customs documentation becomes an important part of the audit trail.
The package may include:
Commercial documents
Sales contract
Commercial invoice
Packing list
Transportation documents
Bill of lading
Air waybill
Delivery order
Customs documents
Import declaration
Customs clearance confirmation
Import permits
Origin documents
Certificate of origin
Other origin-related documentation
Tax documents
Import duty payment
Import VAT documentation
The accounting team should reconcile the customs value, invoice value, and accounting records where relevant.
11. Bank Documents
The bank documents provide evidence that the payment actually occurred.
Typical documents include:
Payment instruction
Foreign currency purchase instruction
Bank transfer application
SWIFT message or confirmation
Debit advice
Bank statement
Exchange-rate confirmation
The bank document should normally be reconciled with the company's accounting records.
For example:
Invoice: USD 30,000Bank transfer: USD 30,000Accounting payable: USD 30,000
Any bank charges, exchange differences, or deductions should be separately identified and recorded.
12. Foreign Currency and Exchange Rate Documentation
Foreign payments frequently create foreign exchange differences.
Suppose:
Invoice:
USD 100,000
Exchange rate at recognition:
VND 25,000/USD
Accounting value:
VND 2.5 billion
If the company subsequently settles the invoice when the exchange rate is:
VND 25,300/USD
the company may recognize an exchange difference.
Therefore, the payment file should retain sufficient evidence of:
Exchange rate used for initial recognition
Exchange rate used for settlement
Amount paid
Bank charges
Foreign exchange gain or loss
This information is particularly important for month-end and year-end accounting.
13. Intercompany Foreign Payments
Payments between related companies require additional documentation because the transaction may be subject to transfer pricing considerations.
Examples include:
Management fees
Technical service fees
Royalty payments
Interest
Cost-sharing arrangements
Shared service charges
Intercompany loans
Reimbursements
The file may include:
Intercompany agreement
Invoice
Service evidence
Allocation methodology
Transfer pricing analysis
Benchmarking study, where applicable
Tax analysis
Board approval
Payment confirmation
The company should be able to demonstrate that the transaction has genuine commercial substance and that the amount charged is supported by the contractual and economic basis of the transaction.
14. Foreign Loan Payments
Foreign loan transactions require a different document package.
For interest payments, the file may include:
Loan agreement
Drawdown documentation
Loan repayment schedule
Interest calculation
Lender statement
Tax calculation
Tax payment evidence
Bank payment instruction
Bank confirmation
For principal repayment, supporting documents may include:
Loan agreement
Repayment schedule
Previous drawdown records
Outstanding balance reconciliation
Payment instruction
Bank confirmation
Companies should also consider applicable foreign-exchange and foreign-borrowing reporting requirements.
15. Dividend and Profit Remittance
Payments of dividends or profits to foreign shareholders may require corporate and tax documentation.
A typical package could include:
Financial statements
Profit allocation documentation
Board resolution
Shareholder resolution
Dividend declaration
Tax clearance or tax compliance evidence, where applicable
Dividend calculation
Shareholder information
Bank payment instruction
Bank confirmation
The company should verify that the relevant corporate and tax conditions for remittance have been satisfied before making the payment.
16. A Practical Foreign Payment Checklist
A useful checklist can be structured as follows:
Document | Goods | Services | Loan | Dividend |
Contract | ✓ | ✓ | ✓ | Sometimes |
Purchase Order | ✓ | ✓ | — | — |
Invoice | ✓ | ✓ | — | — |
Customs Declaration | ✓ | — | — | — |
Delivery Evidence | ✓ | Sometimes | — | — |
Service Acceptance | — | ✓ | — | — |
Tax Analysis | ✓ | ✓ | ✓ | ✓ |
Tax Payment Evidence | If applicable | If applicable | If applicable | If applicable |
Payment Request | ✓ | ✓ | ✓ | ✓ |
Bank Instruction | ✓ | ✓ | ✓ | ✓ |
Bank Confirmation | ✓ | ✓ | ✓ | ✓ |
Board/Shareholder Approval | Sometimes | Sometimes | Often | Often |
The exact requirements depend on the transaction and applicable regulations.
17. Recommended Filing Structure
Companies can create a standardized digital folder for every foreign payment.
For example:
01 – Contract02 – Purchase Order03 – Invoice04 – Delivery / Service Evidence05 – Customs06 – Tax07 – Payment Approval08 – Bank Documents09 – Accounting10 – Other Supporting Documents
A standardized structure makes it easier for accounting teams, internal auditors, external auditors, tax advisers, and management to review transactions.
18. Common Mistakes
Mistake 1: Paying before completing tax analysis
A company may focus on the commercial payment and consider tax afterward.
This can create unnecessary tax risks.
Mistake 2: Contract does not match the invoice
Differences in:
Amount
Currency
Service description
Payment terms
should be investigated and documented.
Mistake 3: Insufficient evidence of services
For consulting, IT, management, or other intangible services, the company should retain evidence showing what was actually delivered.
Mistake 4: Missing customs documentation
For imported goods, the accounting file should be reconciled with customs documentation.
Mistake 5: Ignoring exchange differences
Foreign currency transactions should be properly remeasured and settled in accordance with the applicable accounting framework.
Mistake 6: Weak intercompany documentation
Related-party transactions require particular attention to contractual terms, economic substance, pricing, and tax requirements.
Mistake 7: Treating every foreign payment identically
A USD 10,000 software subscription is fundamentally different from a USD 10 million foreign loan or capital transaction.
The document checklist should therefore be transaction-specific.
19. The Three-Layer Control Framework
A practical way to manage foreign payments is to divide the process into three layers.
Layer 1 – Commercial validation
Confirm:
Contract
Purchase order
Invoice
Goods/services
Delivery or acceptance
Layer 2 – Tax and regulatory validation
Confirm:
Tax treatment
Withholding/FCT
Customs
Foreign exchange
Transfer pricing
Corporate approvals
Other regulatory requirements
Layer 3 – Payment and accounting validation
Confirm:
Payment approval
Bank instruction
Bank confirmation
Accounting entry
Exchange difference
Reconciliation
This creates a strong control environment around cross-border payments.
20. Final Takeaway
A foreign payment should not be viewed simply as a bank transfer. It should be viewed as a complete transaction supported by a clear documentary audit trail.
A well-prepared foreign-payment file should normally connect:
Contract → Invoice → Goods/Services → Tax → Approval → Bank Payment → Accounting
For businesses operating internationally, a standardized foreign-payment checklist can significantly improve the efficiency of finance teams and make tax, audit, and regulatory reviews easier.
The exact documents required depend on the type of transaction, countries involved, currency, contractual arrangement, tax treatment, customs requirements, banking rules, and applicable regulations.
For Vietnam-based companies, foreign payments should be reviewed from several perspectives simultaneously: accounting, corporate approval, tax, customs, foreign exchange, transfer pricing, and banking compliance. The most important principle is to ensure that the payment has a clear commercial purpose and that sufficient documents are retained to demonstrate the substance and legality of the transaction.
