One job, and nothing else: it asks your clients for the items they still owe you for the month, and it asks again on day 3, 7 and 14 counted from the first reminder, for anything still open. All of it without you writing a chase email. Each client gets one email listing their own open items, with your firm's name on it. It is not a portal invitation and there is nothing in it to click. One page shows who still owes what. $50 a month, flat. No call, no demo, no onboarding.
