Harvest
Team members ask about project hours, clients inquire about invoices, managers need budget snapshots. Your AI agent pulls data from Harvest in real time, logs time entries, and sends invoices, all within a single conversation. Billable hours stop falling through the cracks.
Your AI agent becomes a Harvest power user, logging hours, creating invoices, and checking budgets during live conversations without anyone opening the Harvest dashboard.

Discover how agencies, freelancers, and project teams use AI agents to eliminate manual time tracking and streamline the invoicing cycle.
A consultant messages the AI Agent at 6 PM saying they worked 4 hours on the Williams account and 2 hours on internal training. The agent creates both time entries in Harvest, assigns the correct projects and tasks, and confirms the logs. The consultant never opens Harvest. Managers see accurate timesheets without chasing anyone.
A client emails asking why their invoice is higher than expected this month. Your AI Agent pulls the invoice from Harvest, breaks down the line items by project and task category, and explains the charges with specific hour counts. The client gets clarity in minutes. Your finance team avoids a back-and-forth email thread.
A project lead asks how much budget remains on a fixed-fee engagement. Your AI Agent checks Harvest for total tracked hours versus the project budget, calculates the burn rate, and warns that the team will exceed budget in two weeks at current pace. The lead adjusts resourcing before it is too late.

FAQs
The agent uses Harvest's Create Time Entry API, specifying the project ID, task ID, hours, and optional notes. When a team member provides their time via conversation, the agent matches the project name to the correct Harvest project, selects the appropriate task, and submits the entry. The time appears in Harvest immediately.
Yes. The agent uses Harvest's Create Invoice API to generate invoices from tracked time and expenses. It can also use the Create Invoice Message endpoint to email the invoice directly to the client. You control which projects and date ranges are included in each invoice.
Tars connects through OAuth with the harvest:all scope, which grants access to time entries, projects, clients, invoices, and expenses. You authorize this through Harvest's standard OAuth flow. You can revoke access at any time from your Harvest account settings.
No. Tars queries Harvest in real time during each conversation. Time entries, project details, and invoice information are fetched live and used only to respond to the current request. We do not maintain a separate copy of your Harvest data.
Yes. When creating time entries, the agent respects the billable flag on Harvest tasks. If a team member logs time against a non-billable task, the entry is marked accordingly. The agent can also report on billable vs. non-billable totals when pulling project summaries.
Harvest's apps require the user to navigate menus, select projects, and start timers. With Tars, team members simply tell the AI agent what they worked on in natural language. The agent handles the rest. It also works across WhatsApp, SMS, and web chat, and can pull data from other connected tools simultaneously.
Yes. The agent accesses both time entries and expenses through Harvest's API. When a project manager asks for a complete cost picture, the agent combines tracked hours at their billing rates with recorded expenses to provide a full financial overview of the project.
The agent validates the project name against your Harvest project list before creating the entry. If no match is found, it presents the closest matches or the full project list and asks the team member to confirm. No orphaned or misrouted time entries get created.
