Batch vs. On-Demand PDF Generation

PDF generation is a critical function for many businesses, enabling them to produce invoices, reports, contracts, and other essential documents efficiently. TemplateTo offers versatile PDF generation solutions, including batch and on-demand generation. This article compares and contrasts these two methods, providing use cases and benefits for each.

Understanding Batch PDF Generation

Batch PDF generation involves producing a large number of PDFs simultaneously, typically at scheduled intervals or as part of a bulk operation. This method is useful for businesses that need to generate documents en masse.

Benefits of Batch PDF Generation

  1. Efficiency: Batch processing can handle large volumes of data, making it ideal for generating documents for an entire organisation or customer base at once.
  2. Automation: It can be scheduled to run at specific times, reducing the need for manual intervention and ensuring documents are generated consistently.
  3. Resource Management: By scheduling batch processes during off-peak hours, businesses can manage their resources more effectively and avoid system overloads during peak times.

Use Cases for Batch PDF Generation

  1. Monthly Billing Statements: Utility companies and subscription services often need to generate billing statements for all their customers simultaneously. Batch generation ensures that all statements are produced efficiently and on time.
  2. Year-End Financial Reports: Accounting departments can use batch processing to generate financial reports for the entire year, ensuring all necessary documents are prepared for review and compliance.
  3. Mass Mailings: Marketing campaigns that involve sending out thousands of personalised letters or brochures can benefit from batch PDF generation, which allows for the simultaneous creation of all required documents.

Understanding On-Demand PDF Generation

On-demand PDF generation produces documents in real-time, triggered by specific events or user actions. This method is ideal for situations where immediate document creation is necessary.

Benefits of On-Demand PDF Generation

  1. Real-Time Response: Documents are generated instantly, ensuring that users receive their documents as soon as they request them.
  2. Flexibility: On-demand generation can handle individual requests, making it suitable for dynamic environments where document requirements vary.
  3. Personalisation: Each document can be customised based on the user’s specific data or preferences, enhancing the user experience and ensuring relevance.

Use Cases for On-Demand PDF Generation

  1. E-commerce Receipts: When a customer completes a purchase, an on-demand PDF receipt can be generated and sent instantly, providing immediate confirmation of the transaction.
  2. Contract Generation: Legal firms can generate customised contracts on-demand, ensuring that each contract is tailored to the client’s specific needs and circumstances.
  3. Customer Service: In support scenarios, agents can generate and send personalised documents, such as warranty information or service agreements, in real-time based on customer interactions.

Comparing Batch and On-Demand PDF Generation

Efficiency vs. Flexibility

  • Batch Generation: Best for high-volume, routine document creation where efficiency and automation are paramount. It excels in scenarios where the same type of document is needed for many users simultaneously.
  • On-Demand Generation: Offers flexibility and responsiveness, making it ideal for scenarios requiring immediate, individualised document creation. It supports real-time operations and personalisation.

Resource Utilisation

  • Batch Generation: By scheduling during off-peak times, businesses can optimise their resource utilisation, ensuring that large-scale document generation does not interfere with other operations.
  • On-Demand Generation: Requires robust infrastructure to handle real-time requests without delay, which can be resource-intensive but ensures immediate response times.

Customisation and Personalisation

  • Batch Generation: Customisation is possible but may be limited by the need to process large volumes simultaneously. Typically used for standardised documents.
  • On-Demand Generation: Highly customisable, allowing for the creation of documents tailored to individual user data and preferences, enhancing the user experience.

Choosing the Right Solution

The choice between batch and on-demand PDF generation depends on the specific needs of the business. Factors to consider include:

  1. Volume of Documents: High-volume needs may favour batch processing, while individual or low-volume needs may be better served by on-demand generation.
  2. Timing Requirements: If documents need to be generated immediately in response to user actions, on-demand generation is essential. For routine, scheduled document creation, batch processing is more efficient.
  3. Personalisation Needs: Businesses requiring highly personalised documents will benefit from on-demand generation, whereas standardised documents can be efficiently produced in batches.


Both batch and on-demand PDF generation offer distinct advantages and are suited to different business needs. By leveraging TemplateTo’s robust PDF generation capabilities, businesses can choose the method that best fits their requirements, ensuring efficient, timely, and personalised document creation.
