Chasing overdue invoices by hand is a job the system does better: reminder levels, texts, charges, and a batch that creates and sends them.
Tell Me: Reminder Terms: levels (1, 2, 3) with grace periods, texts, and additional fees. Assign the terms to customers. Then Reminders → Create Reminders picks every overdue invoice at the right level, Issue posts them (and any fee to the customer ledger), and Send emails them using the document sending profile. From version 25 there is an automation (Reminder Automation) that runs the whole cycle on the job queue on a schedule, with per-customer exclusions.
Finance Charge Memos work the same for interest. Set it up once in the first quarter after go-live; debtor days usually drop by a week.
