Invoisum

Introduction to Invoisum

Invoisum is a time-tracking and invoicing automation platform designed for freelance software developers and technical consultants. It integrates with development and project management tools—including GitHub, Azure DevOps, and Trello—as well as calendar services such as Google Calendar and Outlook. Rather than requiring manual time entry or post-hoc reconstruction of work activity, Invoisum automatically captures commits, task updates, and scheduled meetings, then structures them into billable entries aligned with clients and projects.

The product targets professionals who bill by the hour or based on activity but prefer to minimize administrative overhead. It eliminates reliance on spreadsheets, standalone timers, or fragmented logging methods by unifying data sources into a single chronological work log. The system supports both individual freelancers and small teams, with no credit card required to begin using the free tier.

Key Takeaways

• Automatic synchronization of GitHub commits, Azure DevOps work items, Trello cards, and calendar events into a unified work log
• One-click generation of professional invoice drafts from time and activity logs
• AI-generated daily summaries that concisely describe completed work for client reporting
• Client- and project-mapping functionality to ensure every logged item is correctly attributed
• Context-aware reminders for invoice submission and follow-up, configured by user-defined cadence
• Frictionless time logging interface that consolidates synced events, manual adjustments, and notes in a single view
• Built-in support for multi-client and multi-project workflows with clear labeling from initial setup

How Invoisum Works

Invoisum operates through a three-stage workflow: connection, logging, and invoicing. First, users connect their existing tools—such as GitHub repositories, Azure DevOps organizations, Trello boards, or calendar accounts—via secure OAuth or API integrations. Once connected, Invoisum begins automatically ingesting relevant activity (e.g., code commits, issue transitions, meeting occurrences) and timestamping each event.

Second, users review the synced activity in a consolidated timeline view. They can adjust estimated durations, add descriptive notes, and assign each entry to a specific client and project. This step ensures accuracy and contextual relevance without requiring real-time tracking. Third, users generate invoices directly from selected date ranges and work logs. Invoices include line-item details, optional AI-generated activity summaries, and export-ready formats suitable for client delivery.

Core Benefits and Applications

Invoisum reduces administrative burden for freelancers who manage multiple clients across distributed toolchains. Its primary application is automating the transition from raw development activity (e.g., merging a pull request, resolving a Jira-linked issue, attending a discovery call) to auditable, client-facing billing records. It supports use cases such as monthly retainer reporting, fixed-scope milestone billing, and time-based consulting engagements where transparency and traceability are valued.

Because it relies on verifiable digital artifacts—commits, tickets, calendar invites—it provides objective evidence of work performed, reducing disputes and reconciliation effort. The AI summary feature delivers standardized, narrative-style reports that replace ad hoc email updates or manually written deliverables. Teams benefit from consistent attribution rules and shared visibility into logged activity without requiring changes to existing development workflows.
