Clients → Debtors is your aged-debt view: who owes you, how much, and how overdue — with balances net of any part-payments and credit notes.
One-click chasing: each row has a reminder button that emails the customer for the outstanding balance, with a tone that matches how overdue it is — friendly at first, firm past 30 days, final past 60. Every chase is logged automatically so you can see who's been reminded and when. The auto-chaser also runs daily in the background, and it never doubles up with one you've sent by hand.
