At NAIway Translation Service, our transactions are exclusively available to corporate clients.
For corporations based in Japan, we offer two payment options:
- Advance Payment (via credit card/via bank transfer)
- Post-payment (via credit card/via bank transfer)
Advance payment is generally required for first-time clients as part of our standard policy.
However, for clients with no business presence in Japan, payment is limited to:
- Advance payment via credit card
- Advance payment via bank transfer
For Advance Payment Clients
We will begin the translation process once we have confirmed receipt of your payment. However, if the payment is made after 3:00 PM[Japan Time], we may not be able to verify it on the same day, and the translation will commence on the next business day.
If you send us a copy of your payment receipt (e.g., a bank transfer slip) as a PDF or JPG via email, we can start the work even if the payment is made after 3:00 PM[Japan Time].
We will notify you by email once the translation process has begun. Please note that, due to our internal procedures, we will issue an invoice instead of a receipt. If you require a receipt, please contact your assigned coordinator.
For Post-Payment Clients
After delivering the requested translation, we will issue an invoice once the review period (typically one week) has passed, provided there are no requests for revisions from the client.
Payment Due Date
Our standard payment term is end-of-month closing with payment due by the end of the following month. Please be sure to check the invoice for the exact due date.
For public funds, research grants, and other institutional payments, we accommodate deadlines in accordance with the respective institution's regulations.
If you require a change to the payment due date, please feel free to contact us. We will do our best to accommodate your request.
