Invoice Reminder Software for Contractors
QuickBooks caps automated reminders at three emails. Dedicated invoice reminder software runs up to 9 steps across SMS and email, from pre-due-date courtesy reminders through 60 days overdue. Here is what to look for and how the tools compare.
QuickBooks Online caps automated reminders at three emails. Once those fire, every invoice that slips past day 30 requires manual follow-up. Dedicated invoice reminder software extends coverage to 7-9 steps across both SMS and email, spanning the full window from pre-due-date courtesy reminders through 60 days overdue.
The short answer
Good invoice reminder software sends SMS and email reminders across multiple follow-up stages, escalates tone as invoices age, and lets you set different rules per customer. QuickBooks offers 3 email reminders maximum. Dedicated tools like Nudge offer up to 9 steps via SMS + email, with per-customer control, starting at $9.99/month.
QuickBooks Caps Reminders at Three Emails and No SMS
Most invoicing platforms include some form of automated reminders. QuickBooks Online lets you set up automatic invoice reminders that go out before or after the due date. You can create up to three reminders and customize the email template for each one.
QuickBooks sends those reminders by email only. It has no SMS option. SAP Engagement Cloud research found that 43% of consumers find SMS a useful channel for receiving information from brands. QuickBooks leaves that channel entirely unused.
Once your three email reminders fire, QuickBooks does not send more. Dedicated tools like invoice automation software extend coverage to 7-9 steps across SMS and email, covering the full 60-90 day payment cycle.
What Good Invoice Reminder Software Includes
SMS Reminders
According to SAP Engagement Cloud research, 58% of consumers are open to hearing from brands several times per week via SMS. Nudge sends SMS reminders at 9 AM EST and lets you assign SMS, email, or both to each of its 9 reminder steps. Your construction, HVAC, plumbing, and landscaping clients receive the reminder as a text during working hours.
Multiple Reminder Steps
Nudge's 9-step schedule spans from 7 days before due through 60 days overdue, a 67-day window. QuickBooks covers three steps. For invoices that regularly stretch past 30 days, those three steps leave the remaining weeks of past-due follow-up to you.
Escalating Tone
A day-3-before-due message might read: "Hey [Client], just a heads-up that invoice #1042 for $2,400 is due on Friday." A day-60-overdue message shifts: "This is a final notice regarding invoice #1042 for $2,400, now 60 days past due. Please remit payment immediately or contact us to discuss." You can reference your late payment policy in the later steps. The software maps your messages to each step and sends them automatically.
Per-Customer Scheduling
Both Nudge plans (Basic at $9.99/month and Pro at $19.99/month) support per-customer scheduling. A reliable repeat customer might only get one pre-due-date email, while a new client gets all 9 steps with SMS enabled on the overdue stages. You can also exclude a customer from reminders entirely.
QuickBooks Integration
Nudge connects to QuickBooks via OAuth, syncs invoice and customer data automatically, and stops reminders when QuickBooks marks an invoice paid. If you are weighing QuickBooks costs after recent price increases, Nudge also works as a standalone tool without QuickBooks.
QuickBooks vs. Dedicated Reminder Software
QuickBooks Online's reminder system stops at three email stages, with no per-customer scheduling and no SMS option. Each reminder sends an email scheduled a certain number of days before or after the due date. You can customize the email subject line and message, and optionally attach a PDF of the invoice.
- Three reminders maximum. Once those fire, QuickBooks stops. If the invoice is still unpaid at 30 or 60 days, manual follow-up is required.
- Email only. No SMS option.
- One schedule for all customers. The same reminder timing applies across the board.
- Flat tone. You can customize the message template, but there is no built-in mechanism to escalate tone as invoices age.

| Feature | QuickBooks Online | Nudge |
|---|---|---|
| Max reminder steps | 3 | 9 |
| SMS reminders | No | Yes |
| Escalating tone | No | Yes |
| Per-customer scheduling | No | Yes |
| QuickBooks sync | Built-in | Yes (OAuth) |
| Standalone use (no QB) | N/A | Yes |
Other invoicing tools have similar limitations. FreshBooks and InvoiceSherpa each handle reminders differently. Chaser focuses on accounts receivable automation for larger teams.
Setting Up Automated Invoice Reminders
- Connect your invoices. If you use QuickBooks, link your account so invoices sync automatically. If not, add invoices manually with the client name, amount, due date, and the invoice file (PDF, Word, or image).
- Set your reminder schedule. Choose when reminders go out relative to the due date. Nudge's default 9-step schedule: 7 days before due, 3 days before due, 1 day before due, on the due date, 3 days overdue, 7 days overdue, 14 days overdue, 30 days overdue, 60 days overdue.
- Choose your channels. Assign email, SMS, or both to each step. Nudge lets you configure this per step.
- Write your messages. Keep early reminders short: "Invoice #1042 is due in 3 days." Let later messages reference your late fee policy. For wording ideas, see how to ask for payment professionally.
- Adjust per customer. Turn off steps for clients who always pay on time. Add the full sequence for new clients or slow payers. In Nudge, the reminder schedule attaches when you create an invoice or sync from QuickBooks.
Nudge: Operational Details
The sections above cover what Nudge does. This section covers how it works day-to-day.
Reminder processing. Nudge processes automated reminders daily at 9 AM EST. You can also trigger an immediate reminder on any invoice with one tap.
Writing messages once, per step. You write the message for each of the 9 steps once. Every new invoice inherits those messages. The day-3-before-due step uses your day-3 message, the day-60-overdue step uses your day-60 message. You write these in your own words.
QuickBooks sync. Nudge connects via OAuth. When QuickBooks marks an invoice paid, Nudge stops all future reminders for that invoice. You do not need to update both systems.
Mark paid without QuickBooks. If you use Nudge standalone, mark an invoice as paid and all future reminders stop. Customers can also mark an invoice as paid themselves through a link in the reminder message.
Pricing. Both plans include a 14-day free trial with no credit card required.
| Plan | Price | Includes |
|---|---|---|
| Basic | $9.99/month | Email reminders, 200 SMS/month, up to 100 active customers |
| Pro | $19.99/month | Up to 10,000 SMS/month, unlimited customers, everything in Basic |
A contractor with 40 active invoices who enables SMS on the day-0, +3, +7, and +14 steps uses 160 SMS per month, within the Basic plan's 200-SMS cap. The Pro plan removes both the customer cap and SMS cap.
Configuring Reminder Timing and Channels
Nudge's 9-step default schedule places the first reminder at 7 days before due and the last at 60 days overdue. Each step can be configured independently for channel (SMS, email, or both) and message content.
Pre-due-date steps (day -7, -3, -1): Nudge defaults these to email. The message content at this stage is typically one line: "Invoice #1042 for $2,400 is due on [date]."
Due-date and early overdue steps (day 0, +3, +7): Adding SMS to these steps puts the reminder on the client's phone at 9 AM EST. The message at day +3 overdue might read: "[Client], invoice #1042 for $2,400 was due 3 days ago. Here's the payment link: [link]."
Late overdue steps (day +14, +30, +60): These steps carry the firmest messages. Reference your late fee policy at day +14. The day +60 message reads: "This is a final notice regarding invoice #1042 for $2,400, now 60 days past due. Please remit payment immediately or contact us to discuss."
For message wording at each stage, see how to ask for payment professionally.
