QuickBooks Invoice Reminders Not Working? 7 Causes and Fixes

If an expected reminder is missing, start with one affected invoice. These seven checks separate an ineligible invoice or schedule mismatch from an email delivery problem.

By PayNudge · Updated September 20, 2026. QuickBooks Online guidance; Desktop uses different settings.

The short answer

First confirm the invoice was already emailed and is still unpaid. Then check the saved reminder toggle, individual schedule and due date. If they match, verify the recipient address and delivery. Need to configure reminders from scratch? Follow the QuickBooks reminder setup guide.

All 7 causes at a glance

Cause	Where to look	Fix
Automatic reminders off	Settings	Check Account and settings → Sales → Reminders; save changes
A schedule is disabled	Reminder 1–3	Check each enabled reminder and its before/after setting
Invoice not eligible	Invoice	Confirm it was already emailed and still has an unpaid balance
Recipient address problem	Invoice and customer	Verify the intended billing contact and correct any typo
Delivery problem	Customer inbox	Check sending errors and ask the recipient to search spam
Due date does not match	Invoice and schedule	Compare the invoice due date with the configured reminder offset
Standard schedule exhausted	Reminder history	Review a manual follow-up; Advanced users can check workflows

1. The toggle is off — or your changes never saved

Open Settings → Account and settings → Sales → Reminders. Select Edit and check that automatic invoice reminders are enabled.

After making a change, select Save, then Done. Reopen the panel to verify what is stored. Record the current settings before changing several things at once so you can tell which correction helped.

2. An individual reminder schedule is switched off

Check each reminder you intend to use, not just the master switch. Compare its enabled state and before/after setting with your intended sequence. For example, a reminder set for three days before the due date will not serve as your three-days-overdue follow-up.

3. The invoice isn’t in a reminder-eligible state

Intuit says automatic reminders apply only to unpaid invoices you have already emailed. Check the affected invoice itself:

Was the original invoice emailed, or only saved or printed?
Does it still have an outstanding balance after payments and credits?
Are you checking the current invoice and its due date, rather than an estimate or an older copy?

A reminder before the due date can be valid too; the invoice does not have to be overdue. A partial payment alone does not mean the remaining balance is paid. If you find an accounting discrepancy, resolve it before asking the customer to pay again.

4. The customer record has no email (or a broken one)

Review the recipient address on the invoice and the customer’s saved contact details. Look for typos or an outdated billing contact. Confirm the address with the customer through a channel you already use; changing reminder wording cannot fix an incorrect recipient.

5. The email may have a delivery problem

Separate “not sent” from “not received.” Look for sending errors or returned messages, then ask the customer to search spam or junk for your business name and invoice number. Do not assume an unpaid invoice means the reminder failed to send.

If a copy reaches your own inbox, that proves only delivery to you. If the customer still cannot find the message, confirm the address before sending another copy and retain any error text for support.

6. Timing isn’t what you assumed

Compare the actual due date with the configured offset. For a September 10 due date, a three-days-after reminder corresponds to September 13. Intuit says rule changes apply to future reminders; its guide does not promise an immediate catch-up send or a specific sending hour. If a follow-up is needed now, review and send a manual reminder rather than repeatedly changing the schedule.

7. The standard reminder sequence has ended

If the configured sequence already ran, decide what the next follow-up should say before sending it:

Standard settings: up to three email reminder schedules, with editable wording for each.
Manual follow-up: review the balance, any dispute and the customer’s last response before another reminder.
QuickBooks Online Advanced: Intuit also offers invoice reminders through workflows. Check your plan before assuming you need another tool.

How to send a reminder now, or escalate to support

In QuickBooks Online, open All apps → Sales & Get Paid → Invoices. Find the invoice, open the Receive payment dropdown and select Send reminder. Review the recipient, balance and message before sending. Avoid a second manual send if another person on your team already followed up.

If an eligible invoice still misses its configured reminder, give QuickBooks support the invoice number, due date, reminder settings, original email date and any error text. That is more useful evidence than a general report that reminders are broken.

Frequently asked questions

Why are my QuickBooks automatic invoice reminders not sending?

First check that you already emailed the invoice and it still has an unpaid balance. Then check the saved automatic reminder settings and whether the due date matches a scheduled reminder. If those checks pass, verify the recipient address and ask the customer to check spam.

Do QuickBooks invoice reminders stop when the invoice is paid?

Yes. QuickBooks Online only sends automatic reminders for open, unpaid invoices. Once an invoice is recorded as paid, its remaining reminders don't send. The flip side: if a payment was recorded against the wrong invoice, the client can keep getting reminders for an invoice they already paid.

How many automatic reminders can QuickBooks Online send per invoice?

The standard reminder settings provide up to three schedules. You can also send reminders manually. QuickBooks Online Advanced has a separate workflow feature for invoice reminders, so three standard schedules is not a universal limit on every QuickBooks plan.

Can QuickBooks send payment reminders by text message (SMS)?

The standard automatic invoice reminders described in Intuit's guide are email reminders. If you use PayNudge for a text follow-up, it prepares an SMS draft on your phone; you review and send it yourself.

Why did my client not receive the QuickBooks reminder email?

Check the recipient address and any sending error first. Ask the customer to search their spam or junk folder for the invoice number. A copy arriving in your own inbox only tests delivery to you; it does not prove delivery to the customer's inbox.

Can I customize QuickBooks invoice reminders per client?

Standard reminder templates apply across invoice reminders, but each of the three reminders can have different wording. For one customer, review a manual reminder before sending. Advanced users should check workflow options for their requirements.
