The Professional Business Letter is a fundamental document in Pakistani business communications, essential for formal correspondence between companies, organizations, and individuals. It serves multiple purposes including business proposals, inquiries, responses, confirmations, and official notifications. The document must comply with Pakistani commercial law, particularly the Companies Act 2017 for corporate correspondence, and the Electronic Transactions Ordinance 2002 when transmitted digitally. Professional Business Letters require specific formatting, including company details, proper letterhead, and appropriate signatory information.

The document's format and content should reflect local business customs while maintaining international business correspondence standards.
