Stacker

Building custom internal tools and client portals in Stacker allows operations teams, founders, and product managers to turn relational databases like Airtable into clean, permission-controlled web applications. Users can update status fields, review account details, and manage workflows without touching underlying database tables.

However, operational workflows inevitably require physical or digital document outputs. When a user in a Stacker portal needs to download an invoice, generate a client proposal, export a work order, or sign a service agreement, standard web portal capabilities run into a technical wall.

Relying on browser-based printing or basic HTML-to-PDF converters results in broken layouts, clipped line items, inconsistent branding, and exposed administrative data. Browser printing cannot parse complex multi-line order items, compute dynamic totals, apply conditional legal disclaimers, or trigger automated delivery workflows.

Integrating dedicated document generation software solves this bottleneck. By connecting your Stacker application and underlying database to an automated document generation engine, you turn structured record data into pixel-perfect PDFs, agreements, and reports with a single button click.

What is Document Generation Software in No-Code Systems?

Document generation software is a technology category that automates the creation of structured, document-based outputs—such as contracts, invoices, shipping labels, and reports—by merging record data from databases into pre-designed visual templates.

In modern no-code ecosystems, document generation software acts as an automated presentation layer. It extracts structured data payloads from systems like Airtable, HubSpot, or custom APIs, processes design rules, and delivers finished, print-ready files to end users or downstream cloud storage.

Core Components of Intelligent Document Automation

• Data Source Connections & Schema Mapping: Direct integration with relational databases that automatically ingests field names, record relationships, and data types without manual field creation.
• Document Template Builder: A visual, drag-and-drop canvas designed specifically for paginated document layouts, supporting standard web design elements and typography through Google Fonts.
• Field Tokens: Dynamic placeholders placed within a template that populate with actual record values during execution.
• Display Rules: Logic parameters that dynamically display or hide content blocks, clauses, or entire layout sections based on incoming data attributes.
• E-Signature Elements: Embedded signature, date, and initial placeholders placed directly into document templates to enable seamless legal execution via native e-signatures.
• Automated Output Routing: Rules that send completed documents directly back to database attachment fields, email recipients, or cloud storage buckets.

Technical Challenges of Generating PDFs in Stacker (And Solutions)

Designing documents directly inside web portal frameworks presents several architectural challenges due to how web browsers handle page rendering versus how documents require paginated structures.

Challenge 1: Rendering Multi-Page Documents and Line-Item Arrays

Web applications render content continuously down a scrollable viewport. Documents, conversely, require explicit page dimensions (Letter, A4, custom label sizes), strict page break calculations, and dynamic headers or footers. When rendering an invoice with a variable number of line items from a linked Airtable base, standard web scrapers fail to calculate page boundaries correctly, often splitting single lines of text across page breaks.

Solution: Dedicated document generation software utilizes purpose-built document engines. Tools like Documint handle repeating elements (loops) natively, automatically calculating vertical spacing and cleanly pushing line items, sub-totals, and signature blocks to subsequent pages when content thresholds are met.

Challenge 2: Field Schema Management vs. Manual Variable Mapping

Traditional document generation tools require operators to manually define every variable string, build complex JSON payloads, and continuously map new fields whenever database schemas evolve. This creates high maintenance overhead for fast-moving SaaS and operations teams.

Solution: Modern no code document automation platforms utilize direct database connections. When connected to Airtable or Stacker data structures, the platform automatically imports the table schema, exposing all available fields as selectable Field Tokens. This eliminates variable syntax errors and reduces template build times from hours to minutes.

Challenge 3: Maintaining Secure User Permissions

Stacker excels at restricting user access to specific records based on roles (e.g., Client A can only view Client A’s invoices). If document generation is handled by client-side browser scripts, sensitive background data or internal fields might leak into the generated source code.

Solution: API-driven intelligent document automation executes document generation entirely server-side. Stacker passes only the specific Record ID via an action button or webhook. The document generation engine fetches the permitted data directly, renders the document securely in an isolated cloud environment, and returns a secure, ready-to-view PDF link back to the user interface.

Step-by-Step Guide: Setting Up Documint with Stacker and Airtable

This guide outlines how to configure Documint to generate automated documents directly from a Stacker portal backed by an Airtable database.

Step 1: Establish Database Connections and Schema

Before designing your template, establish a direct connection between Documint and your primary data store to automatically map available fields.

1. Log into Documint and navigate to the Connections tab.
2. Select Airtable as your integration source and authenticate using OAuth access or your Airtable Personal Access Token.
3. Select the target Base and Table that powers your Stacker application.
4. Documint automatically imports your field schema, making every column—including lookup fields, formulas, and linked record arrays—instantly available in the editor.

Step 2: Build the Visual Layout in the Document Template Builder

Create a visual blueprint for your document using Documint’s visual editor.

• Layout Structure: Drag and drop sections, columns, and containers onto the canvas to define your margins, headers, and footers.
• Styling & Typography: Select brand colors and standard web fonts. Documint natively supports Google Fonts, allowing you to match your exact corporate typography without uploading external font files.
• Inserting Field Tokens: Insert text elements and select dynamic field tokens from your connected schema (e.g., Company_Name, Invoice_Total).

Step 3: Configure Display Rules for Dynamic Content

Instead of building multiple separate templates for different customer tiers or document types, use Display Rules to adapt a single template dynamically.

1. Select any section, text block, or image element inside the Documint editor.
2. Open the Display Rule settings panel in the sidebar.
3. Define the visibility condition based on your record data (e.g., show an Enterprise SLA clause only if Contract_Type equals Enterprise).
4. Save the rule. Elements configured with Display Rules automatically suppress themselves if the condition is not met, leaving no blank gaps in the rendered PDF layout.

Step 4: Add E-Signature Elements for Contracts and Agreements

If your Stacker portal manages agreements, onboarding forms, or legal sign-offs, place native e-signature fields directly inside your document template.

1. Drag an E-Signature Element from the element sidebar onto your template canvas.
2. Assign the signature placeholder to a specific party token (e.g., Client_Email).
3. Position initial and date-signed blocks alongside the signature field.
4. When generated via Documint Sign, the system automatically routes the document to the designated email address, captures legally binding electronic signatures, and stores the signed execution copy.

Step 5: Wire the Generation Button into Stacker

To allow portal users to generate documents on demand, embed a generation link or trigger button inside your Stacker interface.

1. In Documint, navigate to your template's Integrations tab and generate an Airtable Generation Link or webhook trigger.
2. In Airtable, create a Formula Field that constructs the button URL using Documint’s generation parameters.
3. Open Stacker, navigate to the layout settings for your detail view, and add an Action Button linked to the Airtable Formula Field or a native webhook trigger.
4. When a portal user clicks the button inside Stacker, Documint instantly merges the record data, generates the PDF, and attaches the completed file back to the record or opens it directly in a new browser tab.

Comparing Document Generation Approaches for Stacker

Choosing the right technical approach for generating documents from Stacker portals depends on your required document complexity, volume, and budget.

Evaluating Cost Efficiency in Document Automation

Enterprise document tools typically charge steep per-user monthly fees ($19–$65+ per seat/month). For organizations with dozens of portal users, external contractors, or client-facing operations, per-seat licensing models quickly become cost-prohibitive.

Documint uses a volume-based, flat-rate pricing model based on "minted documents" (finished generated files). This ensures that adding more portal users or internal team members to Stacker never increases your document automation software costs.
