OpenWorkpaper

OpenWorkpaper is open-source audit software for teams coordinating workpapers from planning through reporting. It is best suited to CPA firms and internal audit departments able to run their own deployment. Its zero-cost license and structured procedure workflow are compelling; the infrastructure remains the user’s responsibility.

Overview

OpenWorkpaper brings audit programs, client requests, evidence, and review into a single workflow. Its audit-specific structure makes it a stronger fit for teams managing documented procedures than for organizations seeking a broad, general-purpose work platform. Self-hosting gives firms control over where the application and its portable SQLite database run, but requires them to provide and maintain that environment.

Key features

Audit programs cover planning, fieldwork, and reporting. Teams can use templates and evidence collection, and each procedure can capture its purpose, source, scope, methodology, results, conclusions, and reviewer comments. Hierarchical numbering for groups, procedures, and attachments helps keep growing workpapers organized; exporting programs to Word provides a way to work with the audit program outside the application.

A dashboard surfaces active audits, assigned procedures, and pending reviews. Procedure assignments, team management, discussions, and preparer and reviewer sign-offs support a defined handoff from fieldwork to review. PBC tracking centralizes client information requests and supports uploading and downloading a master spreadsheet. Together, these tools suit teams coordinating both audit work and client submissions.

Procedures accept PDF, Word, Excel, and PowerPoint attachments. Role-based access combines system roles with audit-specific team assignments, while OpenID Connect supports Microsoft Entra ID, Okta, and Keycloak. Audit logs track sensitive actions including logins, deletions, procedure unlocking, and user changes. The project documents HTTPS deployment with an Nginx reverse proxy and SSL/TLS certificates, giving self-hosting teams a documented security setup to follow.

Deployment can be local, on a private network, or in the cloud. For up to 200 concurrent auditors, the project recommends 2 to 4 vCPUs, 4GB to 8GB RAM, and at least 20GB of SSD storage. That guidance helps firms size an installation, but the need to provision and operate it favors organizations with infrastructure capacity.

Pricing

The Free / open source plan costs nothing. It includes free open-source audit software that teams self-host on their own infrastructure. There are no paid tiers or seat quotas in the stated plan, making it a straightforward fit for firms that can absorb deployment and upkeep. Teams seeking a vendor-operated service should consider another product.

Platforms

OpenWorkpaper is available as a web application and API, and can be self-hosted. Its support for local, private-network, and cloud deployment gives organizations flexibility over where it runs, while still leaving operation of the environment to them.

Who it's for

CPA firms and internal audit departments are the intended users. It is especially suitable for teams that need procedure-level documentation, evidence, PBC coordination, and reviewer sign-offs, and that can manage a self-hosted application. Organizations looking for a hosted service or broader platform should compare alternatives against those priorities.

Pros and cons

• Free and open source: the software has no stated charge, which makes it attractive to teams able to run their own infrastructure.
• Purpose-built workpapers: procedures capture the core stages of audit work, with hierarchical numbering and Word export helping teams manage and share structured programs.
• Coordinated review and client requests: assignments, discussions, sign-offs, and PBC spreadsheet handling bring common audit handoffs together.
• Self-hosting takes operational capacity: teams must provide the deployment environment and maintain it, so the zero software price does not remove infrastructure work.
• Focused on internal audit: its stated supported audit type is internal audit, which may not suit buyers seeking a broader set of audit types.

Alternatives

Audit Management Software is a useful place to compare more options across the category.

• FlinkISO may suit organizations looking for a broader quality management system: its free on-premise plan includes all QMS modules and unlimited concurrent users, alongside Linux and Windows support.
• SafetyCulture (now Mitti) is a better fit for teams centered on inspections and mobile use. Its free plan supports Android and iOS, with up to 10 seats, 5 active inspection templates, and 300 AI credits per seat per month.
• Diligent Audit is a paid alternative with Android, iOS, web, and API platforms; its pricing is custom.
• Performance Logic Audit and Corrective Actions is a paid option for buyers considering iOS, web, or Windows platforms.
• QSC QS1 is a paid alternative available on Android, iOS, and web.
• Workiva Audit Management may fit organizations seeking customized packaging and unlimited seats or users; it is paid with custom pricing.
• Audrey is another paid option, available on Android and iOS.
• Quantivate Internal Audit is a paid alternative available on web and API.

Verdict

Choose OpenWorkpaper if your firm needs structured internal audit workpapers, PBC tracking, and review sign-offs without a software fee, and can host and maintain the application. Its chief advantage is bringing those audit workflows into open-source software; its chief limitation is the operational responsibility that comes with self-hosting.
