Introduction

Manually emailing customer invoices can consume significant Accounts Receivable time and create inconsistent delivery practices. NetSuite provides several ways to streamline this process, ranging from emailing an invoice when it is saved to sending selected invoices through a Bulk Email Mass Update or implementing fully automated delivery with SuiteFlow, SuiteScript, or an integration platform.

These options serve different purposes. NetSuite’s native Bulk Email capability is user-initiated, while unattended or scheduled invoice delivery generally requires a workflow, script, or integration. This guide explains each approach so you can select the method that best fits your invoice volume, approval process, and control requirements.

Choose the Right Invoice Emailing Method

NetSuite supports several approaches to invoice delivery:

Benefits of Batch Invoice Emailing

Automating invoice delivery provides several advantages:

• Reduce manual administrative work
• Improve invoice delivery consistency
• Accelerate customer payment cycles
• Minimize missed or forgotten invoices
• Standardize invoice email messaging
• Improve customer experience
• Reduce Accounts Receivable processing time
• Scale invoice processing as transaction volume grows

Before You Begin

Before configuring automated invoice emailing, verify the following.

1. Customer Records Have Valid Email Addresses

Navigate to:

Lists > Relationships > Customers

Open a customer record and confirm:

• Primary email address exists
• Invoice recipient email is correct
• Multiple invoice recipients are configured if needed

2. PDF Forms Are Configured

Invoices are typically attached as PDFs.

Navigate to:

Customization > Forms > Advanced PDF/HTML Templates

or

Customization > Forms > Transaction Forms

Verify:

• Invoice form is active
• Proper branding
• Logo
• Payment instructions
• Terms
• Remittance information

3. Email Preferences Are Enabled

Navigate to:

Setup > Company > Email Preferences and review email preferences.

Step 1: Review Transaction Email Preferences

Navigate to:

Setup > Company > Email > Email Preferences

On the Transactions subtab, review the default transaction email settings.

Separately, review invoice approval routing at:

Setup > Accounting > Accounting Preferences > Approval Routing

If invoice approval routing is used, confirm that the Invoices option is enabled and that the approval workflow controls when an invoice becomes eligible for delivery.

4. Correct the customer delivery preference location

The article currently refers to the Communication tab. Oracle’s documentation places the preferred transaction delivery settings on the customer’s Preferences subtab under Send Transactions Via.

Step 2: Configure Customer Delivery Preferences

Navigate to:

Lists > Relationships > Customers

Edit the customer record and open the Preferences subtab. Under Send Transactions Via, select the appropriate delivery method, such as:

• Email
• Print
• Fax
• A combination of methods

Also confirm the email address that should receive transaction communications.

Step 3: Review Invoice Approval Workflow

Organizations using approval workflows should verify that invoices are fully approved before they are eligible for batch emailing.

Navigate to:

Customization > Workflows

Review your approval workflow.

Typical lifecycle:

Draft > Pending Approval > Approved > Available for Email

Only approved invoices should be included in the automated email process.

Step 4: Send Invoice Emails in Bulk

Navigate to:

Lists > Mass Update > Mass Updates

Then:

1. Expand Transactions
2. Select Bulk Email
3. Define the invoice criteria
4. Select the recipient priority
5. Select or create the email message
6. Preview the qualifying transactions
7. Process the update

Oracle specifically documents recipient priority among the transaction email address, customer email address, and contact email address.

Note: Navigation can vary depending on your NetSuite edition, enabled features, and custom roles. Some organizations instead use saved searches combined with scheduled scripts or workflows to automate invoice delivery.

Step 5: Schedule Automatic Batch Processing

Many organizations prefer to send invoices automatically every evening.

This can be accomplished using:

• Scheduled SuiteScript
• NetSuite Workflow
• Map/Reduce Script
• Third-party automation platforms
• Scheduled integrations

Typical automation process:

Invoice Approved

↓

Scheduled Process Runs

↓

Search Approved Unsent Invoices

↓

Generate PDF

↓

Email Customer

↓

Mark Invoice as Sent

↓

Log Activity

While scheduled scripts are a popular option for high-volume invoice processing, many organizations can accomplish their automation goals using NetSuite SuiteFlow. Workflows allow administrators to automatically trigger emails based on business events, such as when an invoice is approved, without extensive custom development. If you’re interested in learning more about configuring automated email notifications with SuiteFlow, check out our article, https://suiteanswersthatwork.com/easily-use-workflows-to-automatically-send-specialized-emails/, which walks through creating workflow-driven email processes in NetSuite. Although that article focuses on specialized email notifications, the same workflow concepts can be applied when designing automated invoice delivery solutions.

Step 6: Monitor Email Delivery

After invoices are sent, review:

Activities > Messages

or

Customer Communication tab

Verify:

• Email sent
• Delivery timestamp
• Sender
• Recipient
• PDF attachment

This provides an audit trail for customer communications.

Optional Enhancement: Use a Saved Search to Drive Automation

Many organizations create a saved search that identifies invoices ready to send.

Example filters:

Transaction Type = Invoice

Status = Open

Approval Status = Approved

To Be Emailed = True

Email Sent = False

Main Line = True

This saved search can be referenced by:

• Scheduled scripts
• Workflows
• SuiteFlow
• Celigo integrations
• REST integrations

This approach offers flexibility and ensures only qualifying invoices are processed.

Troubleshooting

Advanced Automation Options

Organizations with higher transaction volumes often extend NetSuite’s standard functionality.

Examples include:

SuiteFlow

Automatically trigger invoice emails after approval.

SuiteScript

Create custom rules such as:

• Send invoices by customer group
• Delay invoice delivery
• Combine multiple invoices
• Retry failed emails
• Add dynamic attachments

Celigo

Integrate invoice delivery with:

• Customer portals
• Document management systems
• CRM platforms
• EDI providers

SuiteAnalytics

Build dashboards showing:

• Invoices sent today
• Failed email count
• Outstanding invoices
• Average send time
• Customer delivery statistics

Real-World Example

Imagine a wholesale distributor processing 2,500 invoices every month.

Previously:

• AR specialists manually opened each invoice.
• Generated a PDF.
• Attached it to an email.
• Sent invoices individually.

After implementing automated batch emailing:

• Approved invoices were collected throughout the day.
• A scheduled process ran nightly.
• PDFs were generated automatically.
• Customers received invoices within minutes.
• AR staff shifted their focus from administrative tasks to collections and customer support.

The result was faster invoice delivery, improved operational efficiency, and a more consistent customer experience.

Conclusion

NetSuite can support efficient invoice delivery through native transaction emailing, Bulk Email Mass Updates, SuiteFlow, SuiteScript, and integration platforms such as Celigo. The best solution depends on whether invoices should be sent immediately, processed in a user-controlled batch, or delivered automatically on a schedule.

Before enabling automation, establish clear eligibility rules, validate customer email data, standardize invoice forms and templates, and implement controls that prevent duplicate delivery. A well-designed process should also provide visibility into successful sends, failures, retries, and exceptions so Accounts Receivable can manage invoice delivery with confidence.
