Public Sector Platform • Flexum

Overview

A Series A-funded public-sector platform helps government agencies streamline complex administrative workflows, including document creation, procurement processes, contract management, and policy materials.

At the center of its product lies a document authoring experience that must meet unusually high standards of structure, compliance, and collaboration.

Government users draft long, formal documents that follow predefined templates, undergo multi-stage reviews, and must export perfectly into Word and PDF formats.

Building such an experience inside the browser — without breaking user habits or compromising reliability — is an enormous technical challenge.

That’s where Flexum came in.

The challenge

Government documents aren’t like typical text files.

They have strict structure, fixed section order, and multi-department review workflows. Each section may be reviewed and approved by different stakeholders — and all of it must integrate seamlessly with Microsoft Word, where most public employees still work.

Before partnering with Flexum, the team faced three persistent challenges:

Formatting fidelity

Importing and pasting from Word caused layout inconsistencies and lost formatting

Accessibility and export reliability

Content needed to meet strict compliance standards and export flawlessly to Word and PDF

Support dependency

Ongoing editor maintenance relied heavily on costly vendor assistance, slowing iteration

The platform needed a partner who could master this complexity — not just make the editor “work,” but make it trustworthy for government use.

The Flexum solution

Reliable Word interoperability

Flexum implemented a custom in-house logic for pasting and importing content from Microsoft Word.

The result: nested tables, lists, and layout elements now preserve their structure perfectly — a must-have for government templates and standardized RFP forms.

Structured document editing

The editor was extended to support predefined section order and independent review logic, reflecting how public-sector RFPs are reviewed in reality — section by section, reviewer by reviewer.

AI writing assistant

Flexum built a custom AI assistant that suggests content directly within the editor.

Users can preview suggestions inline, as if they were already part of the document — yet the content remains private until explicitly accepted.

This design keeps AI helpful but non-intrusive, respecting user control and collaboration boundaries.

Accessibility and compliance

A real-time accessibility checker was developed, scanning content for visual and structural issues, surfacing warnings inline, and helping authors meet compliance requirements without leaving the editor.

Export and layout consistency

The team enhanced Word and PDF export pipelines, ensuring complete fidelity for headers, footers, tables, and signature blocks — even across multi-root, paginated documents

Typography and formatting controls

Flexum added fine-grained control over font selection, line and paragraph spacing, and layout rules — ensuring consistent appearance across all document stages, from authoring to export.

Foundation for scale and maintainability

All new functionality was delivered within a dedicated plugin monorepository, fully covered by unit and end-to-end tests — ensuring long-term reliability and easy extension.
