How to Build a Document Generation System in Bubble.io
Contracts, proposals, quotes, invoices, certificates and reports: many businesses spend hours copying data into document templates. A document generation system in Bubble.io creates them automatically from your app’s data, consistently formatted and ready to send or sign. This guide covers templates, generation options, e-signatures, secure storage and automation.
What you can generate
- Sales: quotes and proposals from deal data
- Legal: contracts and agreements with client details filled in
- Finance: invoices and statements; see how to build an invoicing system in Bubble.io
- Operations: work orders, delivery notes and certificates
- Reporting: monthly client reports and summaries
Generation options
| Approach | Best for | Trade-off |
|---|---|---|
| PDF plugin | Simple layouts, low volume | Limited design control |
| Document generation service | Professional templates, higher volume | Extra subscription; set up via API |
| HTML template to PDF service | Fully custom designs | More design work up front |
Services are called through the API Connector, usually from a backend workflow so generation completes reliably.
Designing templates
- Separate fixed wording from data placeholders such as client name and totals
- Store reusable clauses or sections as records, so they can be combined
- Keep templates versioned, so you know which version produced each document
- Test with long names, many line items and empty fields
E-signatures
- Generate the document and send it to an e-signature service via its API
- The signer receives an email and signs online
- The service’s webhook tells your app the document is signed, and you store the signed copy
Secure storage
Store each generated file on its related record and protect it with privacy rules, because file links can otherwise be shared. See secure file uploads for the details that matter.
Automation
- Generate a proposal automatically when a deal reaches a stage
- Produce monthly reports for every client with a scheduled job
- Email documents with the file attached; see transactional email
Frequently asked questions
Can Bubble.io generate PDF documents?
Yes. Bubble.io can generate PDFs using plugins or external document services called through the API Connector, turning templates and your app's data into contracts, proposals, invoices or reports.
Which approach is best for generating documents?
Simple documents can use a PDF plugin. For professional layouts, many apps use a document generation service with templates, called from a backend workflow. The right choice depends on design needs and volume.
Can users sign documents generated in Bubble.io?
Yes. Integrate an e-signature service through its API: send the generated document for signature, and let a webhook update your app when it is signed.
Where should generated documents be stored?
Store the generated file on the related record, protected by privacy rules so only authorised users can open it, and keep earlier versions if documents change.
Can documents be generated automatically?
Yes. Backend workflows can generate documents on events, such as a deal being won or a month ending, and email them to the right people.
