In the Patisco system, an "Inquiry" is a purchase request record received from a customer. The system helps you track the source, status, and follow-up progress of each inquiry. A "Quotation" is the formal quotation document you create in response to that inquiry. You can fill in items, unit prices, and terms directly in the system and export it in standard format to send to the customer. The two are linked in the system, making it convenient to track the complete journey from inquiry to transaction.
