In short
An invoice reminder tool is software that sends the follow-up message you'd otherwise write by hand, for every overdue invoice, on a fixed schedule. PayNudge connects to your invoicing tool, sends email reminders automatically at day 1, day 3, and day 7 past due, gives you a one-tap SMS draft for any step, and stops remaining reminders when payment is recorded in PayNudge.
What an invoice reminder tool does
An invoice reminder tool monitors your outstanding invoices and sends follow-up messages to clients on a schedule. Email is the usual channel; PayNudge also gives you one-tap SMS drafts to send from your phone for the reminders that need a faster response.
The tool connects to your invoicing software — Square, Stripe, or a CSV export — and pulls in invoice details automatically. Reminders go out at day 1, day 3, and day 7 past due, with an optional heads-up 3 days before the due date, all without any action from you.
When the invoice is paid, reminders stop automatically. You do not have to update anything.
What the tool actually sends
This is PayNudge's default Step 1 email template. Every business can edit the wording — the merge fields (name, invoice reference, amount, due date) fill in automatically.
Manual follow-up vs. automated invoice reminders
| Manual | Automated (PayNudge) | |
|---|---|---|
| Time spent per invoice | You write and send each one | Review invoice details; emails run automatically once enabled |
| Send timing | You choose when to follow up | Daily run with fixed day 1, 3 and 7 overdue steps |
| Tone stays professional | Depends on your mood | Always consistent |
| Stops remaining reminders | After you check payment | When payment is recorded in PayNudge |
| Works while you sleep | No | Yes |
Which tool do you actually need?
PayNudge is really two tools. Pick based on whether this is a one-off or a recurring problem.
One invoice, right now
Use the free payment reminder generator. No signup, no setup — describe the situation, pick a tone, and get a message to send today.
Every invoice, going forward
Use PayNudge itself. Connect your invoicing tool once, and every future overdue invoice gets the day 1 / day 3 / day 7 sequence automatically — no re-typing the reminder every time.
Who needs an invoice reminder tool
Any service business that invoices on terms (net-15, net-30, or milestone-based) will benefit. The problem scales with the number of clients: if you have 10 active invoices, manual follow-up is annoying. If you have 50, it becomes a significant time sink.
PayNudge is built for trades and home services (plumbers, electricians, landscapers), professional services (consultants, bookkeepers, designers), and field service businesses (cleaners, pest control, HVAC).
- You currently follow up on invoices manually
- Invoices regularly go more than 7 days overdue
- You use Square or Stripe
- You want clients to get reminders even when you are busy

Invoice reminder tool — frequently asked questions
What is an invoice reminder tool?
An invoice reminder tool tracks outstanding invoices and sends email follow-ups on a schedule. PayNudge also prepares SMS drafts you send from your phone. Remaining reminders stop when payment is recorded in PayNudge; integrations sync daily.
How is it different from following up manually?
Manual follow-up only happens when you remember and have time for it. An invoice reminder tool sends every reminder on schedule, in a consistent professional tone, and stops remaining reminders when payment is recorded in PayNudge. Integrations sync daily; you can mark an invoice paid manually between syncs.
Does it work with Square or Stripe?
Yes. PayNudge connects to Square and Stripe through their official APIs, and also accepts a CSV export from any other invoicing tool. You don't change how you invoice today.
Can it send SMS reminders, not just email?
Yes. PayNudge sends email reminders automatically and gives you a one-tap SMS draft that opens in your phone's Messages app, pre-filled and ready to send — useful for later-stage reminders, where a text tends to get noticed faster than email. PayNudge never sends SMS on its own; you always tap send yourself.
Is this the same as the free reminder generator?
No — they solve different problems. The free generator writes one message for one invoice, right now, with no signup. This tool (PayNudge itself) is the recurring version: connect your invoices once and it keeps sending the right reminder at the right time, for every invoice, without you opening the tool again.
What does the invoice reminder tool cost?
CA$2 per distinct overdue invoice when the first qualifying email is confirmed delivered to the receiving server. Remaining follow-ups for that invoice are included. Maximum CA$29 per monthly billing period before taxes; no qualifying usage means CA$0. Same CAD pricing worldwide. A 14-day free trial needs no card; after the trial, set up payment to send new paid sequences.
How long does setup take?
A few minutes. Connect your invoicing tool or upload a CSV, and the tool runs on its own from there — the reminder schedule is already set up by default.
