A quotation becomes an order, an order becomes an invoice, an invoice becomes a receipt — each step carries the last one's data and posts to the same ledger. Sell in your customer's currency; report in yours.
The deal you quoted is the deal you invoice — because it's the same document, moved forward.
Collections start with knowing the number. The statement to send is one click further.
"What's our position with this customer?" is a page, not a meeting.
