Can I charge a late fee, set terms, or change my invoice numbers?

The Settings tab on Get Paid holds the defaults every new document starts from, in three sub-tabs. Invoices: payment terms (net 30 and the rest), a late-fee rate, a default tax rate, the level of pricing detail shown, and the tip setting for the pay page. Quotes: how many days a quote stays open, the deposit asked on acceptance, the note and the terms printed on every quote, and whether follow-ups go out on day 3 and day 7. Contracts bill through the invoice defaults, and the Contracts sub-tab says so. Each invoice or quote can override its own terms when you write it. The late fee is stated on the invoice and on the pay page so the customer sees it before it applies. These live here rather than in Settings on purpose — they are about the documents you send, not the business.
