Translation / English

I am a bit worried about doing a transaction through bank remittance instead of PayPal since this is the first transaction for us. Would it be possible for you to prepare a sales agreement or an invoice including your company’s name? (You can send it to me as a PDF file attachment.)
We have an account in Union Bank, so it is possible to transfer money to your company’s account.
Thank you for your cooperation.
We hope to build a good business relationship with your company.

Sincerely,

Translation / English

As this is the first time we do business with you, we are a little nervous about our process in paying you by bank transfer and not Paypal.
Therfore, to help the process go smoothly, would it be possible for you to send us a purchase and sales contract or an invoice that has the name of your company imprinted thereto ? (A PDF version attached to an email would be fine too ) .
We have an account at Union Bank so we are of course able to pay by bank transfer to your account.

We are sorry for any inconveniences caused by this but we hope you will bear with us and we hope to be great business partners with you.

Kind regards,
