In short
Payment reminder software is a category of tool that automatically follows up on unpaid invoices instead of you writing every reminder by hand. PayNudge is built specifically for small service businesses: it sends email reminders on a fixed, tested cadence — day 1, day 3, and day 7 past due — gives you a one-tap SMS draft for any step, connects to QuickBooks, Square, Jobber, and Stripe, and stops the moment a client pays.
The hidden cost of chasing late payments
Chasing late invoices is a quiet tax on a service business. The hours spent writing follow-up emails are hours not spent on billable work, sales, or running the business. Worse, most people feel uncomfortable asking for money — so they delay, which pushes the invoice further past due.
Payment reminder software removes the discomfort entirely. You connect your invoices once, and the software handles the rest on a fixed schedule. Your clients get professional, timely follow-ups. You get paid faster without the awkward conversation.
PayNudge ends that cycle: every overdue invoice gets chased for you — automatically, in your name, through a three-step email sequence at day 1, day 3 and day 7 past due, stopping the moment it is paid.
Everything you need to get paid on time
Built specifically for service businesses that invoice clients.
Email + one-tap SMS
Email reminders send automatically. For any step, get a one-tap SMS draft that opens in your phone — you send it yourself, and every message looks like it came from you.
Connects to your tools
QuickBooks, Square, Jobber, and Stripe sync automatically. Overdue invoices flow in without any manual work.
A fixed, tested cadence
Day 1, day 3, and day 7 past due — plus an optional reminder 3 days before the due date. PayNudge fires each message on schedule and stops when paid.
Fully customizable wording
Every message uses your business name and reply-to address. Edit the subject and body per step to match your voice — polite, firm, or final notice.
Stops automatically on payment
The moment an invoice is marked paid — or your integration syncs — the sequence stops. No embarrassing follow-ups after payment.

Works with your existing invoicing software
You do not need to switch invoicing tools. PayNudge connects on top of what you already use.
- QuickBooks Online: Syncs invoices automatically. Overdue invoices trigger reminders without any manual input.
- Square: Pulls your Square invoices and monitors payment status in real time.
- Jobber: Connects to your Jobber account and follows up on outstanding jobs.
- Stripe: Monitors Stripe invoices and fires the overdue reminder sequence — plus the optional pre-due reminder, if you switch it on.
- CSV import: Use any invoicing software? Export a spreadsheet with customer name, amount, and due date. PayNudge does the rest.

Payment reminder software — frequently asked questions
What is payment reminder software?
Payment reminder software automatically follows up on overdue invoices for you — sending professional email reminders on a schedule, giving you one-tap SMS drafts to send from your phone, and stopping the moment a client pays. It replaces the manual chasing most small businesses do by hand.
How much does PayNudge cost?
PayNudge starts at CA$29/month with a 14-day free trial and no credit card required to start. Businesses in lower-income countries pay a fair local price — from CA$10/month — confirmed in your currency at checkout.
Do I have to switch my invoicing software?
No. PayNudge connects to QuickBooks Online, Square, Jobber, and Stripe through their official APIs, and accepts a CSV export from any other tool. You keep invoicing exactly the way you do today — PayNudge just adds the follow-up layer on top.
Will my clients know the reminders are automated?
No. Reminders send from your business name and your reply-to address, in wording you control and can edit. Clients reply directly to you, just as they would to an email you wrote yourself.
When do the reminders stop?
The moment an invoice is marked paid — or a connected integration syncs the payment — the remaining reminders for that invoice stop automatically. There is no follow-up after a client has already paid.
Does PayNudge need access to my bank account or my money?
No. PayNudge connects to your invoicing tool to read invoice and payment status — it doesn't move money, and it can't. It's a reminder layer that sits on top of the accounting or payments tool you already use.
Is PayNudge accounting software?
No. PayNudge doesn't replace QuickBooks, Square, Jobber, or Stripe — it connects to whichever one you already invoice with (or a CSV) and handles the follow-up on what's unpaid. Think of it as the layer that chases the invoice, not the layer that creates it.
Is there anything to install?
No. PayNudge runs in your browser. There is nothing to download or install, and setup takes a couple of minutes.
