What can you do with the Harvest connector?

Harvest is a time tracking and invoicing platform used by agencies, consultancies, and professional services teams to log hours, manage budgets, and bill clients. Integrating Harvest with your broader tech stack means real automation — syncing time entries with project management tools, pushing invoice data to accounting software, and triggering alerts when budgets creep toward their limits. With tray.ai, you can build workflows that keep Harvest data accurate across every system your team depends on.

Use case

Automated Invoice Sync to Accounting Software

When a Harvest invoice is created or marked paid, automatically push that data to QuickBooks, Xero, or your accounting platform of choice. This cuts the double-entry burden that hits finance teams at the end of every billing cycle and reduces the risk of invoices slipping through the cracks.

Eliminate manual re-entry of invoice data between Harvest and accounting tools
Keep payment status in sync across finance and project management systems
Cut month-end close time by automating reconciliation data flows

Use case

Project Budget Monitoring and Alerting

Monitor Harvest project budgets in real time and trigger automated alerts via Slack, email, or Microsoft Teams when a project hits 75%, 90%, or 100% of its allocated hours. Project managers get visibility before things go sideways, without having to manually check Harvest dashboards.

Notify project managers before budgets are exceeded
Automatically escalate alerts to account owners when thresholds are breached
Create Jira or Asana tasks to review scope when budget overruns occur

Use case

Time Entry Sync from Project Management Tools

Pull task completions or logged hours from Jira, Asana, or ClickUp and automatically create or update corresponding time entries in Harvest. Billable hours get captured even when team members forget to log time directly in Harvest.

Capture billable hours from every source without requiring manual Harvest entry
Keep project task completion and billable time in sync across platforms
Reduce revenue loss from underreported time entries

Use case

New Client and Project Provisioning

Apply billing rates and budgets from the CRM deal accurately
Reduce project kickoff delays caused by manual Harvest setup

Use case

Maintain an audit trail of timesheet approvals across systems

Use case

Challenges Tray.ai solves

Common obstacles when integrating Harvest — and how Tray.ai handles them.

Challenge

Keeping Harvest and Accounting Systems in Sync

Finance teams often manage invoices in both Harvest and an accounting platform like QuickBooks or Xero, which leads to duplicate data entry, reconciliation errors, and delayed payment tracking when the two systems drift apart.

How Tray.ai helps

tray.ai listens for Harvest invoice events via webhooks and immediately mirrors changes to your accounting platform, using field mapping and conditional logic to handle edge cases like partial payments, write-offs, and credit notes — no manual intervention needed.

Challenge

Capturing All Billable Time Across Fragmented Tools

Teams working across Jira, Asana, GitHub, and other tools often fail to log billable time in Harvest consistently, causing revenue leakage and inaccurate project profitability reports.

How Tray.ai helps

tray.ai connects Harvest to any project management or development tool and automatically creates time entries from task completions, pull request merges, or logged work. Billable hours don't get lost regardless of where the work actually happens.

Challenge

Manual Project Setup After Sales Handoffs

After a deal closes in the CRM, project or operations teams have to manually recreate client and project details in Harvest, introducing delays, data mismatches, and billing rate errors that can sour client relationships early.

How Tray.ai helps

tray.ai automates the entire project provisioning process by triggering on CRM deal stage changes and mapping contract details directly into Harvest. Clients, projects, and billing configurations are created in seconds with no one touching it manually.
