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 and lets you configure timing, channels, and wording for the invoices you are following up on. QuickBooks' standard automatic reminders support up to 3 emails. Dedicated tools like Nudge offer up to 9 selectable due-date-based stages per invoice via SMS + email, 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 processes enabled reminders daily at 9 AM Eastern Time and lets you choose SMS, email, or both for each invoice. Your construction, HVAC, plumbing, and landscaping clients receive the reminder as a text during working hours.
Multiple Reminder Steps
Nudge supports up to 9 fixed due-date-based reminder stages per invoice. QuickBooks' standard automatic reminders support up to three email stages. For longer collection cycles, additional selectable Nudge stages can keep past-due follow-up automated.
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-Invoice Scheduling
Both Nudge plans (Basic at $9.99/month and Pro at $19.99/month) support per-invoice stage controls. Enable or disable individual due-date-based stages and choose email, SMS, or both for the invoice, or exclude a customer from reminders entirely. Pro adds custom reminder message templates.
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 standard automatic reminders support up to three email stages with configurable timing and message content. Nudge adds SMS and supports up to nine due-date-based reminder stages with per-invoice stage controls.
- 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-invoice 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 up to 9 reminder stages and set when each one goes out relative to the due date.
- Choose your channels. Choose email, SMS, or both for the invoice. Nudge applies that channel selection to its enabled stages.
- 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 invoice. Enable or disable stages for the specific invoice and choose email, SMS, or both for that invoice.
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 Eastern Time. 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 credits/month, up to 100 customers and 20 active invoices |
| Pro | $19.99/month | 750 SMS credits/month, unlimited customers and invoices, everything in Basic |
A contractor with 40 active invoices who sends four SMS reminders on each invoice would use 160 SMS credits, within the Basic plan's 200-credit monthly allowance. Pro includes unlimited customers and invoices plus 750 SMS credits per month.
Configuring Reminder Timing and Channels
Nudge offers up to 9 fixed due-date-based stages per invoice. You can enable or disable individual stages and choose email, SMS, or both for the invoice. Built-in messages generally become firmer as invoices age; Pro adds custom reminder message templates.
Reminders are processed daily at 9 AM Eastern Time. A message can also include Nudge's secure mark-as-paid confirmation link; Nudge does not process customer payments.
