Automated invoice reminders across up to 9 fixed due-date-based stages. Choose which stages are enabled for each invoice, choose email, SMS, or both for that invoice, connect QuickBooks if you use it, and let Nudge handle the follow-up.
Every invoice can use up to 9 fixed stages tied to its due date. Toggle individual stages on or off per invoice, then let Nudge follow up automatically.
| Stage | Timing | Built-in message style |
|---|---|---|
| Before due | 7, 3, or 1 day before | Advance reminder / friendly heads-up |
| Due date | On the due date | Due reminder |
| After due | 3, 7, 14, 30, or 60 days overdue | Progressively firmer follow-up |
Enable or disable individual stages per invoice and choose email, SMS, or both for the invoice. Pro users can customize reminder message templates. Reminders are processed daily at 9 AM Eastern Time.
Most invoice tools focus on email. Nudge supports email, SMS, or both at the invoice level, giving contractors another way to reach customers when email alone is easy to miss.
Every SMS includes your business name and opt-out instructions. Built-in consent-recording and SMS opt-out controls let recipients reply STOP to opt out. Businesses remain responsible for obtaining appropriate consent.
On Pro, set custom subject lines and body text for each reminder step — or use the built-in defaults. Merge fields like {{customer_name}}, {{amount}}, {{due_date}}, and {{business_name}} personalize every message automatically.
Pro users can set different wording for individual stages or write a single catch-all template. Basic uses the built-in stage-specific messages.
Not every invoice needs the same treatment. Toggle individual reminder stages on or off for each invoice and choose email, SMS, or both for that invoice.
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 — Pro users can use a saved custom template, while the generic option 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 Android. Check reminder history and send manual reminders from the job site. Everything syncs across devices in real time.
Reminders can include a secure mark-as-paid link. When the customer confirms they have already paid, future reminders stop automatically. Nudge does not process customer payments.
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.
