How teams ship better PDFs

FinFlow

FinTech / SaaS

Challenge

FinFlow generates thousands of investment reports daily. Their Puppeteer setup crashed during market volatility, causing 5-second timeouts and angry customers.

Solution

Migrated to PDF API in one afternoon. Used HTML templates with Handlebars variables for dynamic charts and tables. Sandbox mode for CI/CD testing.

Results

• Zero rendering timeouts since migration
• Customer support tickets related to PDFs dropped by 94%
• Engineering team reclaimed 2 days/month previously spent on browser maintenance

InvoiceHero

SaaS / Billing

Challenge

InvoiceHero's Puppeteer cluster required 6 dedicated containers, constant memory leak monitoring, and weekly restarts. Infrastructure costs grew linearly with customer growth.

Solution

Replaced the entire Puppeteer cluster with HTTP calls to PDF API. Templates stored in the dashboard, rendered with customer data via the REST API.

Results

• Reduced infrastructure from 6 containers to zero
• PDF generation cost per invoice dropped by 60%
• Scaled from 10K to 150K invoices/month without touching infrastructure

LegalTech GmbH

Legal / Compliance

Challenge

LegalTech generates confidential contracts and NDAs for enterprise clients. Every prospect required a security review proving GDPR compliance and data residency.

Solution

PDF API's EU-hosted infrastructure with automatic data purging satisfied every Data Protection Officer. Base64 font embedding eliminated external CDN calls.

Results

• Security review timeline shortened from 3 weeks to 2 days
• Won 2 enterprise deals worth €180K ARR specifically due to compliance architecture
• Zero data retention policy became a competitive advantage in RFPs
