Set up automatic email and SMS reminders for unpaid invoices — before the due date, on the due date, and for overdue invoices.
Invoice reminders eliminate the need to manually chase unpaid invoices. The HoopAI Platform can automatically send follow-up messages to customers on a schedule you define — before the due date to prompt early payment, on the due date as a final nudge, and after the due date for overdue accounts.
Invoice reminders require at least one email template or SMS template to be set up in your account. Go to Marketing → Email Templates or Conversations → Templates to create message templates before configuring reminders.
When you create or send an invoice, the reminder schedule you have configured is attached to that invoice. The platform tracks the invoice due date and fires each reminder at the specified time relative to that date.Reminders stop automatically as soon as:
The invoice is fully paid
The invoice is voided
You manually disable reminders on the specific invoice
Reminders continue even if the customer has made a partial payment — they stop only when the invoice balance reaches zero.
Global reminder settings apply to all invoices by default. Any invoice you create will automatically inherit this reminder schedule unless you override it on an individual invoice.
1
Open invoice settings
Go to Payments → Invoices & Estimates and click the gear icon in the upper-right corner to open Settings. Select Reminder settings.
2
Add a reminder step
Click Add reminder to create your first reminder. You can add as many reminder steps as you need — for example, a 7-day before, 3-day before, on-due-date, 3-day after, and 7-day after sequence.
3
Configure each reminder
For each reminder step, fill in the following:
Reminder name — an internal label for easy identification (e.g., “3-day overdue notice”)
When to send — select Before due, On due date, or After due, and enter the number of days
Channel — choose Email, SMS, or Both
Email template — select an existing email template or click Preview to create a new one
SMS template — select or create an SMS template (if SMS is selected)
Reminder frequency — how many days between repeat sends (if you want the reminder to repeat)
Max reminders — the maximum number of times this reminder fires (set to 1 for a one-time send)
Business hours restriction — optionally restrict sends to your configured business hours only
Time zone — send relative to your business time zone or the customer’s time zone
4
Add additional reminder steps
Click Add another reminder to chain multiple reminders together. You can configure an entire sequence — for example:
Reminder 1: 7 days before due — Email
Reminder 2: 3 days before due — Email and SMS
Reminder 3: On due date — Email
Reminder 4: 3 days after due — Email and SMS
Reminder 5: 7 days after due — Email
Toggle any reminder off to temporarily disable it without deleting it.
5
Save
Click Save. The new reminder schedule is now active for all new invoices. Existing invoices already in circulation are not affected — see the note below.
Changes to global reminder settings apply only to new invoices created after you save the settings. Invoices already sent before the change retain their original reminder schedule.
You can override the global reminder schedule on any specific invoice to give it a different sequence — or to turn off reminders entirely for that invoice.
1
Open the invoice
Go to Payments → Invoices & Estimates, find the invoice in the list, and open it.
2
Locate the reminders section
In the invoice editor, scroll to the Reminders section (available under Additional options or in the invoice settings panel).
3
Override or disable
To disable all reminders for this invoice, toggle the Reminders switch off.
To use a custom schedule, deselect “Use global settings” and configure the reminder steps specifically for this invoice.
4
Save
Save the invoice. The per-invoice reminder configuration takes precedence over the global settings.
Each reminder message supports merge tags (custom values) to personalize the content dynamically. Use these in your email subject lines and message bodies:
Merge tag
Inserts
{{contact.first_name}}
Customer’s first name
{{invoice.number}}
Invoice number (e.g., INV-042)
{{invoice.amount}}
Total invoice amount
{{invoice.due_date}}
Invoice due date
{{invoice.payment_link}}
Direct link to the online payment page
{{invoice.balance}}
Remaining unpaid balance
{{business.name}}
Your business name
Always include the {{invoice.payment_link}} merge tag in every reminder message. This gives customers a one-click path to pay without having to search for the original invoice email.
Open individual invoice → Additional options → Reminders
Use global reminders to set your standard follow-up sequence, and use per-invoice overrides only when a specific client relationship requires a different approach — for example, turning reminders off entirely for a VIP account that you prefer to contact personally.
In addition to time-based payment reminders, you can configure event-based invoice notifications. These fire when a specific thing happens to an invoice, not at a scheduled time.Go to Payments → Invoices & Estimates → Settings → Notifications to configure:
Event trigger
When it fires
Invoice sent
When you send the invoice to the customer
Invoice viewed
When the customer opens the invoice link
Invoice paid
When full payment is received
Invoice overdue
When the due date passes without payment
Partial payment received
When the customer pays an installment
For each event, you can select a custom email template and control whether a notification goes to the contact, to your team, or both.
For more advanced reminder logic — such as conditional sequences that branch based on whether a customer has viewed the invoice — use the Automation module instead.
1
Open workflows
Go to Automation → Workflows and click + New Workflow.
2
Set the trigger
Add a trigger and select Invoice. Choose from:
Invoice Sent
Invoice Overdue
Invoice Paid
Invoice Viewed
3
Build the reminder sequence
Add Wait steps to introduce time delays, then add Send Email or Send SMS actions. Use If/Else conditions to branch the flow — for example, stop the sequence if the invoice has been paid (check invoice status in the condition).
4
Activate the workflow
Turn on the workflow. It will now fire for every invoice that matches the trigger conditions.
Workflow-based reminders give you the most flexibility — you can check whether the customer has viewed the invoice and send a more urgent message only to contacts who have seen the invoice but not yet paid.
For large invoices where you prefer a more personal touch on overdue notices:
Step
Timing
Channel
Purpose
Reminder 1
14 days before due
Email
Early awareness
Reminder 2
7 days before due
Email
Upcoming notice
Reminder 3
3 days before due
Email + SMS
Urgent reminder
Reminder 4
On due date
Email
Due today
Reminder 5
5 days after due
Email + SMS
First overdue
For high-value accounts, disable the automated overdue reminders (steps 4 and 5 in the high-value sequence) and handle overdue follow-up with a personal phone call or email instead. You can toggle off individual reminder steps without deleting them.
You can confirm whether a reminder was delivered to a contact by checking the contact’s activity feed:
Go to Contacts and open the contact record
Click the Activity tab
Look for email or SMS delivery events associated with the invoice number
If a reminder email bounced or an SMS failed to deliver, the activity log will show the failure reason. You can resend manually from the Conversations module if needed.
Yes. When configuring each reminder step, set the channel to SMS or Both (email and SMS). You must have an SMS template assigned and a phone number connected in your account for SMS delivery to work.
Do reminders stop if a customer partially pays?
No. Reminders continue until the invoice is fully paid. A partial payment reduces the outstanding balance but does not stop the reminder sequence. Only full payment or voiding the invoice stops reminders automatically.
Can I customize the reminder email template?
Yes. Click the edit icon next to each reminder step to open the template selector. You can choose an existing email template or create a new one. Use merge tags to personalize the subject line and body with the customer’s name, invoice amount, due date, and payment link.
Are reminder settings applied retroactively to existing invoices?
No. Changes to global reminder settings only apply to new invoices created after you save the change. Invoices that have already been sent retain the reminder schedule that was active when they were created.
Can I set up reminders for estimates?
No. Reminders are invoice-specific. Estimates have their own expiry date notification but do not support the same time-based reminder sequence as invoices. Once an estimate is converted to an invoice, the invoice reminder schedule applies.
What is the difference between reminders and notifications?
Reminders are time-based follow-ups for unpaid invoices — they fire a specified number of days before or after the due date to prompt the customer to pay. Notifications are event-based alerts that fire when something happens to an invoice (sent, viewed, paid, overdue). Both can be configured independently and serve complementary purposes.
Can I turn off all reminders for a specific invoice?
Yes. Open the invoice, scroll to the Reminders section in Additional options, and toggle the reminders switch off. This disables all reminders for that invoice only, without affecting any other invoices or your global settings.
Can I set a maximum number of reminder sends so it does not send indefinitely?
Yes. In each reminder step, set the Max reminders field to limit the total number of times that reminder fires. For example, set Max reminders to 3 with a 7-day frequency for an overdue reminder that sends a maximum of three times over three weeks, then stops.
Can I restrict reminders to business hours so customers do not receive messages late at night?
Yes. Each reminder step has an optional Business hours restriction toggle. When enabled, the system waits until your next configured business hours window before sending the reminder, even if the scheduled send time falls outside those hours.
Will recurring invoice reminders work the same way as regular invoice reminders?
Yes. Each invoice generated by a recurring template is treated as an independent invoice. If you configure reminders on the recurring template, every generated invoice inherits that reminder schedule and behaves identically to a manually created invoice for notification purposes.
