Building a Reporting System

Dashboards are interactive. Reports are snapshots. A report generated today shows today's data. Tomorrow it's stale. Reports are good for distribution (email, PDF, sharing) and archives. Understanding the difference matters.

Dashboard vs Report

Dashboard: interactive, always up to date, self-serve exploration. Great for analysts and power users.

Report: static snapshot, emailed on a schedule, formatted for reading/sharing. Great for executives who don't log in daily.

Scheduled Report Generation

Generate reports automatically on a schedule. Daily summary email. Weekly performance report. Quarterly business review PDF.

Backend service: cron job or scheduler runs at specified time, generates report, sends it.

PDF Generation

Puppeteer (headless Chrome) can render HTML and export as PDF. Render your dashboard HTML, screenshot it, convert to PDF.

Or react-pdf for programmatic PDF generation. Declare content in React, export to PDF. More control, more complex.

Tradeoff: Puppeteer is simpler (reuse existing HTML), react-pdf is more customizable.

Email Delivery

Send reports via email. Attach PDF or include HTML summary.

Make reports actionable. "Revenue is down 5% this week" is better than just a number. Include comparison and context.

CSV/Excel Export

People like spreadsheets. Provide CSV export of dashboard data. Users can analyze further in Excel.

Often more useful than PDF. Users can filter, sort, pivot the data themselves.

Report Parameters

Let users customize reports. "Generate a report for Q4 in the EU region." A form to set parameters, then generate.

Simple form: select date range and filters, generate.

Report Archive

Store generated reports in S3. Users can access past reports. "I want to see last month's report."

Archive enables history and comparisons.

Who Needs Reports vs Dashboards

Executives often prefer email reports over logging in. Designers might want weekly design metrics. Finance wants monthly statements.

Analysts want dashboards. Operations wants dashboards. Executive stakeholders often prefer reports.

Report Scheduling Systems

Simple: cron job + email service.

More sophisticated: Metabase, Looker, or built-in scheduling (many BI tools have it).

Cloud services like AWS Lambda with EventBridge can trigger report generation.

The Report as Retention Tool

For B2B SaaS, automated reports showing customer value are a retention tool. "You saved 10 hours this week with our product." Email it weekly.

Customers who see value are less likely to churn. Reports demonstrating value increase retention.

Template Reports

Build report templates. Sales team has a template, support team has another. Each template has placeholders for parameters.

Users select a template, set parameters, generate. Reduces the need for custom reports.
