A customer order should not become three disconnected files.
In Cayamanan, a quotation holds the customer, products, quantities, prices, taxes, and terms. When the customer agrees, the same record becomes a sales order. Stockable items can create delivery work for the warehouse, while invoiceable items can move into Accounting according to your policy.
The fictional demo shows this clearly: sales order S00004 links the customer promise to its delivery and to invoice INV/2026/00001. Sales can answer the customer, the warehouse sees what to deliver, and Finance can understand why the invoice exists.
