What is the difference between a quotation, a challan and an invoice?
A quotation is a price offer, a challan is a delivery, an invoice is the sale that posts to the books.
• Quotation — a price offer to a customer. It does not touch the books or your stock. Convert it to a sale when the customer accepts.
• Delivery challan — records goods leaving your premises, usually before the invoice is raised.
• Sale invoice — the actual sale. This is the one that posts to the ledger and moves stock.
Use a quotation while you are still negotiating, and an invoice once the sale is real.

How do I add freight, duty and clearing charges to imported stock?
Open the purchase bill, choose Extra costs, and attach each cost bill as it arrives. Imports lists every bill still waiting for its costs.
How do I record a payment I received or made?
Payments → New payment: pick the party, pick the cash or bank account, enter the amount.
How do I return goods to a supplier?
Purchase returns are raised against what you actually bought from that supplier and still hold.
What does a purchase order do?
A purchase order records what you have ordered. Nothing posts until you enter the bill.
