No. The limit is an alert, not a lock: the record flags the balance above the limit and the collections board lists it, but the quote can still be sent. If you want a brake before selling, approval rules hold a quote by amount, discount or margin until someone with permission approves it; they're on the Scale plan.

On the day your client approves the quote. That date drives the due date they see on the link, the aging in the account statement and when the sale enters your overdue receivables. Terms are chosen on each quote (from due on receipt to Net 90), and the record stores each client's terms.

Yes. You upload a CSV with company, contact, email, phone, tax number, terms and credit limit; if a client already exists, matched by tax number or company name, it's updated instead of duplicated. You can also export the full directory whenever you need it.

Anyone with the Clients permission, the same one that creates and edits records; the rest of the team can view them. Note that the Rep role has that permission by default. If you'd rather only your admin team touch limits and terms, remove it in Settings › Team & roles; inviting more people is available from Professional.
