Nudge
Most contractors lose hours every week chasing unpaid invoices manually. Nudge fixes that — add an invoice once and it automatically follows up until the customer pays. Users add invoices, and the system sends reminders on a customizable schedule, stopping once payments are marked as paid to streamline collections and minimize administrative tasks. Default reminders are sent three days before, on the due date, and at intervals of three, seven, and fourteen days after. Users can customize schedules up to thirty days overdue and choose email, SMS, or both. Messages can be personalized with templates and merge fields for customer names and invoice details. The platform integrates with QuickBooks for easy invoice imports, reducing manual entry. Additional features include customer management, invoice attachments, email notifications for sent reminders, and tracking unpaid, overdue, and paid invoices.
