Use Cases

FUNBREW PDF automates PDF generation across industries. From API integration to workflow design, we help you get started.

Accounting

Automated invoice generation with instant email delivery

Challenge

Hundreds of invoices were created in Excel monthly, manually converted to PDF, and emailed. Over 20 hours/month of staff time.

Solution

Send invoice data via API. Embed amounts and line items into a template, generate PDF, and email directly to customers.

Result

20 hours/month → fully automated. Zero missed invoice deliveries.

    html: renderInvoice(orderData),
    email: { to: customer.email, subject: "Your invoice is ready" },
  }),
});

HR & Education

Dynamic certificate generation

Challenge

E-commerce & Logistics

Automated packing slip generation

Challenge

Multiple manual steps between order confirmation and packing slip printing caused shipping delays.

Solution

Webhook from order management system triggers API. PDF generated on order confirmation and saved to S3. Warehouse staff prints directly from S3.

Result

Fully automated from order to packing slip. Shipping lead time reduced by half a day.

Implementation example

# Order webhook → PDF generation → S3 upload
res = requests.post(
    f"{API_BASE}/api/pdf/generate-from-html",
    headers={"Authorization": f"Bearer {API_KEY}"},
    json={"html": render_packing_slip(order)},
)
s3_url = res.json()["data"].get("s3_url")

Real Estate & Legal

Contract PDF conversion and archiving

Challenge

Contracts created via web forms had no PDF conversion pipeline. Stored as HTML, causing formatting issues during audits.

Solution

Convert contract HTML to PDF via API. Add CONFIDENTIAL watermark and archive to S3 for long-term storage.

Result

Automated formal PDF archiving. Smooth audit compliance.

WatermarkS3API Integration

Implementation example

// Contract PDF + watermark + S3 archive
$res = Http::withToken($apiKey)
    ->post("{$apiBase}/api/pdf/generate-from-html", [
        'html' => $contractHtml,
        'watermark' => 'CONFIDENTIAL',
    ]);
$s3Url = $res->json('data.s3_url');

Internal IT

Daily report PDF generation with Slack delivery

Challenge

Manual dashboard screenshots posted to Slack every morning. Frequent misses and delayed information sharing.

Solution

Cron sends dashboard URL to API for PDF conversion. Slack Webhook delivers automatically with download link.

Result

Automated daily reports to Slack at 9 AM. Eliminated dependency on individuals.

URL to PDFSlackWorkflow

Implementation example

# cron: Convert dashboard to PDF every morning
res = requests.post(
    f"{API_BASE}/api/pdf/generate-from-url",
    headers={"Authorization": f"Bearer {API_KEY}"},
    json={"url": "https://bi.internal/dashboard/daily"},
)

Healthcare

Patient-specific lab report PDF generation

Challenge

No system for per-patient PDF output. Inefficient print → scan → email workflow.

Solution

Embed test items, values, and assessments into templates. Generate per-patient PDFs and send directly via email.

Result

Same-day result delivery. Paperless, reduced mailing costs.

TemplatesEmailAPI Integration

Implementation example

// Generate lab report from template + email
const res = await fetch("/api/pdf/generate-from-template", {
  method: "POST",
  headers: { "Authorization": `Bearer ${API_KEY}` },
  body: JSON.stringify({
    template: "lab-report",
    variables: { patient_name: "Jane Smith", test_date: "2026-03-21" },
    email: { to: "patient@example.com", subject: "Your lab results" },
  }),
});

Legal / LegalTech

Automated Contract PDF Generation with Watermarks

Challenge

Contracts were manually converted from Word to PDF, with 'CONFIDENTIAL' watermarks added one by one. Growing contract volume made this unsustainable.

Solution

Contract templates inject party names, dates, and terms as variables. Watermarked PDFs are generated automatically and archived to S3.

Result

Contract creation: 10 min → instant. Audit-ready archiving fully automated.

    variables: { company_a: "Acme Corp", company_b: "Widget Inc", date: "2026-04-01" },
    watermark: "CONFIDENTIAL",
  }),
});

E-Commerce / SaaS

Instant Receipt PDF on Payment Completion

Challenge

Receipt reissue requests required manual handling each time. Month-end batch issuance meant processing hundreds of receipts by hand.

Solution

Stripe webhooks trigger real-time receipt PDF generation from order data, automatically emailed to customers. Monthly batch issuance also supported.

Result

Receipt issuance fully automated. Support ticket volume reduced by 90%.

        "email": {"to": customer_email, "subject": "Your receipt"},
    },
)

Events / Entertainment

Batch Event Ticket PDF Generation

Challenge

Thousands of tickets were designed and exported individually in design tools. Event prep took days every time.

Solution

Ticket templates inject attendee names and seat numbers. Batch API generates all PDFs at once with unique download links.

Result

Ticket issuance: days → minutes. Download limits prevent scalping.
