What Is International Invoicing?
International invoicing is the process of billing a client located in another country for products or services provided.
Unlike domestic invoices, international invoices often include:
- Foreign currencies
- International payment methods
- Tax declarations

How to Invoice International Clients Step-by-Step
Step 1: Collect Client Information
Before creating the invoice, collect:
- Client name
- Company name
- Billing address
- Accounts payable email
- Tax information
- Preferred payment method
Confirm all details before sending the invoice. Incorrect information can delay payment.
Step 2: Choose the Correct Currency
One of the first decisions is choosing the invoice currency.
The most common currencies are:
- USD (US Dollar)
- EUR (Euro)
- GBP (British Pound)
- CAD (Canadian Dollar)
- AUD (Australian Dollar)
Generally:
- Invoice in the client’s currency if they request it.
- Invoice in your local currency if agreed beforehand.
- Clearly state the currency on every invoice.
For example:
Total Due: USD $2,500
Never assume the client knows which currency you’re using.
Step 3: Create a Professional Invoice
Your invoice should include:
- Unique invoice number
- Client details
- Service descriptions
- Quantity
- Rates
- Total amount due
- Currency
- Payment instructions
Step 4: Add Tax Information
Tax requirements depend on:
- Your country
- The client’s country
- Type of service
- Business structure
Common tax-related items include:
- VAT
- GST
- Reverse charge statements
- Tax registration numbers
When in doubt, consult a qualified tax professional.
Step 5: Add International Payment Methods
The easier it is to pay, the faster you’ll get paid.
Provide multiple payment options whenever possible.
Examples:
- Wise
- PayPal
- Payoneer
- Stripe
- Bank Transfer
Step 6: Set Payment Terms
Common international invoice payment terms:
| Payment Term | Meaning |
|---|---|
| Due Upon Receipt | Immediate payment |
| Net 7 | Due within 7 days |
| Net 15 | Due within 15 days |
| Net 30 | Due within 30 days |
For most freelancers and agencies, Net 15 provides a good balance between flexibility and cash flow.
Step 7: Send the Invoice
Most international invoices are sent via:
- Client portal
- Invoicing software
PDF is the preferred format because it maintains consistent formatting.
Step 8: Track Payment Status
After sending:
- Confirm receipt
- Monitor due dates
- Record payments
- Update accounting records
Invoice tracking prevents overdue invoices from being forgotten.
Step 9: Follow Up Professionally
If payment is late:
- Send a reminder before the due date.
- Follow up on the due date.
- Follow up again after 7 days.
- Escalate politely if necessary.
Many international payments are delayed simply because the invoice was overlooked.

International Taxes Explained
Tax rules vary significantly by country. Always consult a qualified accountant or tax advisor for specific advice.
VAT
VAT (Value Added Tax) is commonly used in Europe and many other countries. Depending on the transaction, VAT may need to be charged or reported.
GST
GST (Goods and Services Tax) is commonly used in countries such as:
- Australia
- Canada
- New Zealand
GST requirements vary by jurisdiction.
Sales Tax
Sales tax applies mainly in the United States. Whether sales tax applies depends on:
- State regulations
- Product type
- Service type
Reverse Charge Mechanism
Many B2B international transactions use a reverse charge mechanism. Under this arrangement, the customer accounts for VAT instead of the supplier.
W-8BEN
A W-8BEN is commonly requested from non-US freelancers and businesses working with US companies. It helps establish foreign tax status.
W-9
US-based contractors often provide a W-9 form to clients for tax reporting purposes.
1099
US businesses may issue Form 1099 to qualifying independent contractors. Understanding these forms helps avoid payment and compliance issues.
Common International Invoicing Mistakes

How to Get Paid Faster by International Clients
Request Deposits
For larger projects, request:
- 30% upfront
- 50% upfront
This reduces risk.
Use Milestone Billing
Break large projects into payment milestones. This improves cash flow and reduces outstanding balances.
Offer Multiple Payment Methods
Give clients flexibility. The fewer barriers to payment, the faster payment arrives.
Use Net 15 Terms
Shorter payment terms generally result in faster payments.
Send Automated Reminders
Many overdue invoices are paid immediately after a reminder.
Offer Early Payment Incentives
Example: “2% discount if paid within 5 days.”
This can encourage faster payment.
