A financial transaction is any event that changes what the business owns, owes, or has earned: a sale, a bill, a payment, a deposit, a loan draw, an owner contribution. In the books it becomes a journal entry (or the invoice, bill, or bank match that creates one).

Examples
A bank draft that is the actual event
You sign a $4,000 monthly lease. No books entry on the signature. On May 1 the landlord drafts $4,000. Debit rent $4,000, credit checking $4,000. If you close April on accrual, you may post rent and a payable on April 30, then clear it when the draft hits.
A project that creates two transactions
A customer signs a $12,000 project. You invoice $4,000 at kickoff: that invoice is a transaction (accounts receivable and income on accrual). The ACH later is a second transaction: cash in, AR down.
Why it matters
If it changed cash, invoices, bills, or debt, it belongs in the general ledger. If you only record 'real' payments and skip bills and invoices, the reports lie. Double-entry bookkeeping is how each transaction stays balanced.

Yes, something happened at the bank. Your job is to match it to the right accounts. A transfer between two business accounts is a transaction that should not hit income or expense.
