S-Contract — Document Workflow

A tool that turns a Word contract template into a shareable form, collects filled submissions from external parties, routes them through an approval workflow, and produces the final signed-ready DOCX and PDF — automatically.

Challenge

Organizations reuse the same contracts over and over, but the process is manual: copy a template, fill the blanks, email it around, chase approvals, and re-export to PDF every single time.

Solution

• Template variables: upload a DOCX with {{ placeholders }} and the app extracts them into a structured form — even when Word splits a placeholder across internal runs.
• Shareable forms: generate public links with optional OTP email verification, allowed-domain restrictions, expiry, and submission limits.
• Approval workflow: auto-approve when validation passes, or route for manual review with approve / reject (and resubmit) — with email notifications at each step.
• Document generation: on approval, the filled DOCX is produced with PHPWord and converted to PDF via headless LibreOffice, all on background queues.

Technical Implementation

Laravel 13 with two Filament 5 panels (admin + public form), PHPWord for templating, and LibreOffice for PDF conversion. Deployed with Nixpacks + RoadRunner (Octane) and a supervisor-managed queue. Tested with Pest and a GitHub Actions CI pipeline.
