Automated invoice reminders that start friendly and escalate until you're paid. SMS + email, QuickBooks sync, and nothing you have to remember to do yourself.
Every invoice gets up to 9 reminders on a fixed schedule tied to the due date. Early reminders are friendly nudges; later ones escalate in urgency. You don't write the follow-up sequence — it runs automatically.
| Step | Timing | Tone |
|---|---|---|
| 1 | 7 days before due | Friendly heads-up |
| 2 | 3 days before due | Gentle reminder |
| 3 | 1 day before due | Due tomorrow |
| 4 | On the due date | Due today |
| 5 | 3 days overdue | Past due notice |
| 6 | 7 days overdue | Follow-up |
| 7 | 14 days overdue | Urgent |
| 8 | 30 days overdue | Final warning |
| 9 | 60 days overdue | Last notice |
You can enable or disable any individual step per invoice. Reminders fire daily at 9 AM EST.
Most invoice tools only send email. Nudge sends both SMS and email — or either one individually. Text messages get read within minutes, not days. For contractors chasing payments from busy clients, SMS is the difference between getting paid this week and next month.
Every SMS includes a STOP opt-out link and your business name. Nudge handles consent tracking and TCPA compliance automatically.
Set custom subject lines and body text for each reminder step — or use the defaults. Merge fields like {{customer_name}}, {{amount}}, {{due_date}}, and {{business_name}} personalize every message automatically.
Set a different tone for early reminders vs. overdue ones, or write a single catch-all template that covers every step.
Not every client needs the same treatment. Toggle individual reminder steps on or off for each invoice. Disable the 7-day-before step for a long-standing customer, or turn off the 60-day overdue step if you handle late collections manually.
Changes take effect immediately — steps that have already fired won't re-send.
Don't want to wait for the daily schedule? Open any invoice and tap Send Reminder Now to fire the most recent due reminder immediately. Works for backdated invoices too — choose between your custom template or a generic message that reflects the actual overdue status.
Connect your QuickBooks account and import open invoices and customers in one step — no manual data entry. Nudge syncs daily to pick up new invoices automatically and marks invoices as paid when the balance hits $0 in QuickBooks.
You can also trigger a manual sync anytime. Nudge only reads your QuickBooks data — it never writes back or modifies your books.
No accounting software? No problem. Add customers and invoices directly in Nudge. Enter the client name, amount, due date, and reminder channel — reminders start firing automatically. Works for contractors who invoice by hand, use PDF templates, or just need a simple follow-up system.
Nudge works as a web app and as a native mobile app on iOS and Android. Create invoices, check reminder history, and send manual reminders from the job site. Everything syncs across devices in real time.
Every reminder includes a link your customer can click to mark the invoice as paid. When they do, all future reminders stop automatically. No back-and-forth texts or calls asking "did you get my payment?" — the customer confirms it themselves.
Attach your original invoice PDF when creating an invoice in Nudge. The attachment is included as a download link in email reminders so your customer has the full document without you needing to send it separately. SMS reminders note that the attachment is available via email.
Let Nudge handle the follow-up so you can focus on the work.
