A. In simple terms, it’s anything that affects your profit and loss or balance sheet. The below is taken from our knowledge base:
B. No. Estimates aren’t included in this count.
C. As above, typically anything that affects profit and loss, or balance sheet will count. This includes bank transactions, invoices (both sales and purchases), journals and payments.
If an invoice is created … it’s then paid (and I enter this in my business current account) this counts as 2 (or 1) ledger entry?
Also if enter a purchase … and then pay for it on a credit card (but don’t actually store credit card transactions on QF) … does this just count as 1 ledger entry?
Just to add to what @ian_roberts has said, from an invoice preview you can go to More Options >> View nominal ledger entries. This will show you exactly what entries are linked to the invoice you’re viewing.
