Dear :

I would like to apply for a $ credit line with your company. From your invoices no. [invoice numbers] you will note that I have done a large deal with you on a cash basis over the past months.

I am sure these cash orders have adequately established my credit. If, however, you require further credit data, I have authorized to release banking and creditor information directly to you. You may contact [name] at [phone number].

I would be very grateful if you could give me an early reply. Please call me at if you have any questions.

Sincerely yours,

[name]
