Nudge is an automated invoice reminder app built for contractors and small service businesses, plumbers, HVAC technicians, electricians, cleaners, landscapers, and anyone who invoices clients and regularly deals with late or unpaid payments.
The problem: most contractors are too busy, or too uncomfortable, to manually chase unpaid invoices. QuickBooks sends up to three email reminders and stops entirely. Nudge keeps following up automatically - via SMS and email - with messages that escalate in tone from friendly, to firm, to final notice, until the invoice is marked paid.
Features:
SMS and email reminders on a fully customizable schedule, up to 9 reminders per invoice
Escalating tone sequences: write a friendly first reminder, a firmer second, a final notice - Nudge sends them in order in your exact words, no AI rewriting
QuickBooks integration: connect your QB account and invoices and customers sync automatically on a daily basis
Per-customer control: exclude specific customers from reminders, or set a different schedule per client
Mark any invoice paid to instantly stop all further reminders
Manual send: trigger a reminder immediately without waiting for the next scheduled send
Reminder history log: every invoice shows a full timeline of what was sent, when, and by what method
Nudge isn't trying to replace QuickBooks, it works alongside it. Most small contractors already use QB for their books. Nudge fills the gap QB doesn't cover well: persistent, multi-channel follow-up that keeps going until the money actually lands.
Use QuickBooks for the books. Use Nudge to get paid.
