Generating a few dozen reports manually is tedious. But what happens when you need to send 5,000 personalized monthly statements to customers? Or 10,000 quarterly investment summaries to partners?
If you're a finance operations manager, wealth management team lead, or CTO responsible for customer-facing reporting, you've likely faced the challenge: How do we generate and deliver thousands of personalized documents reliably, on schedule, without errors or missing deliveries?
The "export one report at a time and email it" approach breaks down fast. You need a batch processing system that handles volume, tracks delivery, manages failures, and provides audit trails showing exactly which customers received their documents.
This guide shows you how to set up reliable batch report generation and delivery workflows—the patterns that separate ad-hoc report exports from professional, scalable operations.
The Challenge: Moving From Manual to Automated Batch Delivery
What Works for Small Volumes (But Fails at Scale)
The Manual Approach:
- Finance team generates reports one at a time through the UI
- Each report is downloaded and manually emailed to the customer
- Someone keeps a spreadsheet of who received their report
Why this breaks:
- Takes hours or days to process hundreds of customers
- Human errors: wrong report sent to wrong customer, duplicates, or missed recipients
- No audit trail proving who received what and when
- Can't meet tight deadlines (month-end, quarter-end reporting)
What Enterprise-Ready Batch Processing Looks Like
Automated Batch Generation:
- Define your recipient list (customers, accounts, partners)
- Configure report parameters for each recipient (date ranges, account numbers, personalization)
- Schedule generation for off-peak hours or trigger on-demand
- System generates all reports using background jobs
- Reports are automatically delivered via email or uploaded to Google Drive
- Complete audit trail tracks every step: generation, delivery, failures
Key benefits:
- Process 10,000 reports in hours instead of days/weeks
- Zero manual effort after initial setup
- Automatic retry on transient failures
- Proof of delivery for compliance and auditing
Core Concepts for Reliable Batch Processing
1. Track Individual Recipients, Not Just "The Batch"
The mistake: Treating the entire batch as one job. If it fails halfway through, you don't know who received reports and who didn't.
The solution: Track each recipient individually.
Example: Monthly Customer Statements
Instead of thinking "generate 5,000 statements" as one task, think:
- Batch Run #12345: "January 2026 statements for all active customers"
- Customer A001: Generated, ✓ Delivered
- Customer A002: Generated, ✓ Delivered
- Customer A003: Generation failed (data issue) - flagged for review
- Customer A004: Email delivery failed (invalid address) - flagged for review
- Customer A005: In progress...
Why this matters:
- If the system crashes or needs to restart, it resumes from where it left off
- You can retry only the failed recipients without regenerating everything
- You have a complete audit trail showing exactly who received their document
- You can answer "Did customer X receive their January statement?" instantly
2. Handle Failures Gracefully (Not Everything Will Succeed)
At scale, failures are normal. What matters is how you handle them.
Types of failures you'll encounter:
Transient Issues (Retryable):
- Network timeout during email delivery
- Temporary database slowness
- Rate limits from email service
- Temporary server unavailability
Action: Default rate limiting and automatic retry mechanism in case of failure.
System Capacity Issues:
- Too many reports in queue
- High server load
Action: Throttle or delay. Retry during off-peak hours.
Data Issues (Require Manual Review):
- Customer record missing required fields
- Invalid date ranges or parameters
- Data validation errors
Action: System flags the failure. Operations team reviews and fixes the underlying data issue, then manually reprocesses that specific recipient.
3. Prove Delivery with Audit Trails
For compliance and customer service, you need to prove:
- Which reports were generated
- When they were delivered
- Who they were sent to
Example audit trail:
Batch Run: January 2026 Customer Statements
Start Time: 2026-02-01 02:00 AM
Completed: 2026-02-01 05:30 AM
Summary:
- Expected: 4,823 recipients
- Successful: 4,811
- Failed: 12
Individual Records:
- Customer A001: Generated 02:05 AM, Delivered 02:06 AM (email)
- Customer A002: Generated 02:05 AM, Delivered 02:07 AM (email)
- Customer A003: Failed - Missing account data (flagged for review)
- Customer A004: Generated 02:10 AM, Delivery failed (invalid email)
Why this matters:
- Auditors can verify every delivery
- Customer service can instantly confirm if a customer received their report
- You can identify and fix data issues before the next batch
- You have evidence for compliance requirements
How to Set Up Batch Processing with CxReports
CxReports provides robust batch generation and delivery infrastructure. Here's how to leverage it:
Step 1: Prepare Your Recipient List and Data
What you need:
- List of recipients (customers, accounts, partners)
- Data for each report (parameters, account numbers, date ranges)
- Delivery preferences (email addresses, Google Drive connection)
CxReports approach: You can provide data in multiple ways depending on your volume and architecture:
1. Query-Based (Recommended for Large Batches - 10,000s+):
- CxReports queries your data source directly for each report
- Supported sources: SQL databases, MongoDB, APIs, Google Sheets
- Configure data source connection once, CxReports handles querying during generation
- Most efficient for high volumes (tens of thousands of reports)
- Database does the heavy lifting of filtering and aggregating per recipient
2. Push Method (Better for Lower Volumes):
- Your system prepares and sends data to CxReports before generation
- Data can be provided as:
- JSON files - Stored and reused across multiple report runs
- CSV files - Stored and reused across multiple report runs
- Temporary data (via API) - Pushed just-in-time, cleaned up after report generation completes
Step 2: Configure Report Parameters
For each recipient, define:
- Which report template to use
- Parameters (customer ID, date range, account numbers)
- Branding/theme (especially for multi-tenant scenarios)
- Output format (PDF, Excel, etc.)
Example: Quarterly investment statements
- Template: "Quarterly Investment Statement"
- Parameters per recipient:
- Customer ID: varies
- Quarter: "2026-Q1"
- Account IDs: varies per customer
- Logo/Theme: Customer-specific branding
Step 3: Use Background Jobs for Generation
CxReports leverages background job processing for batch generation:
Key features:
- Reports are generated in batches using worker pools
- System automatically manages concurrency and resource allocation
- Built-in retry logic for transient failures
- Progress tracking and status monitoring
How it works:
- Submit Job generation request (via UI or API)
- CxReports queues individual report jobs
- Background workers pick up jobs and generate reports in parallel
- Generated reports are stored and ready for delivery
- System tracks status: queued → processing → completed/failed
Benefit: You can generate thousands of reports overnight without manual intervention. Schedule generation during off-peak hours (2 AM - 6 AM) to minimize impact on daytime operations.
Step 4: Automate Delivery to Recipients
CxReports provides delivery options:
Email Delivery:
- Configure email recipients per report
- Attach generated PDF to email
- Customizable email templates
- Automatic retry on transient delivery failures
- Error logs track delivery issues
Google Drive Upload:
- Upload generated reports to Google Drive
- Configure folder access and permissions
- Multiple reports can be merged within the same folder into a consolidated PDF
- Ideal for organized storage and team access
Step 5: Monitor and Reconcile
After batch generation, verify:
Completion Metrics:
- How many reports were expected?
- How many completed successfully?
- How many failed and why?
CxReports provides:
- Batch job status dashboard
- Success/failure counts
- Individual item tracking
- Error logs for failed items
Reconciliation checklist:
- ✓ All expected recipients have generated reports
- ✓ Failed items are reviewed via error logs
- ✓ Delivery confirmations received (emails sent, files uploaded)
- ✓ Audit trail captured (who received what and when)
- ✓ Failed items scheduled for manual review

Result: Professional, branded invoices for all partners without manual document creation.
Best Practices for Batch Processing
1. Schedule During Off-Peak Hours
Run large batches overnight or during low-usage periods to minimize impact on interactive users.
2. Test with Small Batches First
Before running 10,000 reports, test with 10-50 recipients to validate:
- Data is correct
- Reports render as expected
- Delivery works properly
- Timing is acceptable
3. Monitor Performance Trends
Track over time:
- Average generation time per report
- Peak processing times
- Failure rates and common errors
- Queue depth during batch runs
Identify performance degradation early.
4. Communicate with Recipients
For scheduled deliveries, set expectations:
- "You will receive your monthly statement by the 2nd of each month"
- "Quarterly reports are delivered within 3 business days of quarter-end"
- Provide customer service contact if reports are missing
5. Have a Failure Recovery Plan
Define what happens when:
- Entire batch fails (system outage)
- Individual reports fail (bad data)
- Delivery fails (invalid email addresses)
Document who is responsible for monitoring and resolving issues.
Conclusion: From Manual Chaos to Automated Operations
Moving from manual report generation to automated batch processing transforms operations:
Before (Manual):
- Days or weeks to generate hundreds of reports
- High error rates and manual tracking
- No audit trail
- Staff time consumed by repetitive tasks
After (Automated with CxReports):
- Hours to generate thousands of reports
- Low error rates with automatic retry
- Complete audit trail for compliance
- Staff focuses on exceptions and strategic work
Key takeaway: Batch processing isn't about writing code—it's about configuring reliable workflows. CxReports provides the infrastructure (background jobs, queue management, retry logic, delivery automation) so you can focus on your business logic (recipient lists, data preparation, delivery preferences).
