What is payup?
Open-source Slack bot that chases overdue invoices: reads QuickBooks or Wave, drafts gentle-to-firm reminders, and sends via Gmail only after you approve. No database, no payment rails, no auto-send. A human-in-the-loop alternative to Bill.com-style dunning for founders, freelancers, and bookkeepers. MIT.
