# Connect Harvest to Xero > Stop re-entering data by hand. Sync billable hours, invoices, and project costs between Harvest and Xero automatically. **Canonical page:** https://tray.ai/connectors/harvest-xero-integrations/ **Harvest connector:** https://tray.ai/connectors/harvest-integrations/ **Harvest documentation:** https://tray.ai/documentation/connectors/service/harvest **Xero connector:** https://tray.ai/connectors/xero-integrations/ **Xero documentation:** https://tray.ai/documentation/connectors/service/xero ## Overview Harvest and Xero do different jobs — one tracks time and project budgets, the other handles accounting and cash flow. They work well together, but without an integration, your team ends up manually exporting invoices, re-entering client data, and chasing down discrepancies across both platforms. Connecting Harvest and Xero through tray.ai means billable time flows straight into accurate, ready-to-send invoices, and your books stay current without anyone touching them. For agencies, consultancies, and professional services firms, time is literally money. The gap between logging hours in Harvest and getting paid through Xero is exactly where revenue leaks and delays happen. When these two platforms are connected, approved timesheets automatically generate invoices in Xero, new Xero contacts get created when clients are added in Harvest, and payments received in Xero update project statuses back in Harvest. That end-to-end automation cuts billing errors, shortens payment cycles, and gives finance teams a real-time view of project profitability without ever leaving their tools. Teams save hours of admin work each week while making sure every billable minute gets captured and invoiced. ## Use cases ### Automatic Invoice Creation from Harvest Timesheets When a Harvest invoice is generated or approved, tray.ai creates a matching invoice in Xero with all line items, hours, and rates accurately mapped. Finance teams don't have to re-enter anything, and billing goes out faster. The integration handles currency, tax codes, and client references so both systems stay in sync. - Cut invoice generation time from hours to seconds - Eliminate manual data entry errors in billing records - Get invoices to clients sooner and improve cash flow ### Client and Contact Synchronization When a new client is added in Harvest, tray.ai automatically creates a matching contact record in Xero, complete with name, email, billing address, and currency preferences. Your accounting system always reflects your active client roster without anyone doing it twice. Updates to client details in either system can also be pushed across to keep records consistent. - Maintain a single source of truth for client contact data - Prevent duplicate or mismatched client records across platforms - Save admin time when onboarding new clients ### Payment Status Updates from Xero to Harvest When an invoice is marked as paid in Xero, tray.ai updates Harvest to reflect that payment status, giving project managers real-time visibility into which clients have settled their accounts. Both platforms stay in sync and nobody has to reconcile statuses by hand. Teams can also use this signal to trigger follow-up workflows or unlock next project phases. - Give project teams instant visibility into payment status - Eliminate manual reconciliation between accounting and project tools - Trigger downstream workflows when payment milestones are hit ### Project Budget and Cost Reporting tray.ai can pull project cost data from Harvest — including tracked hours against budget thresholds — and push summary reports or journal entries into Xero for accurate cost-of-goods-sold and project profitability accounting. Finance leaders get a clear picture of project margins without exporting and manipulating spreadsheets. Automated reporting schedules keep data current at month-end close. - Improve project profitability visibility in real time - Speed up month-end close with automated cost entries - Reduce reliance on manual spreadsheet exports and reconciliations ### Expense Sync from Harvest to Xero Expenses logged against projects in Harvest are automatically pushed to Xero as billable expense line items or purchase records, so out-of-pocket costs land in your accounting system without delay. Each expense is attached to the correct client, project, and tax category. Finance teams can review and approve expense records in Xero without chasing team members for documentation. - Capture every billable expense without manual re-entry - Ensure correct tax treatment and categorization of project expenses - Reduce month-end close time by keeping expense records current ### Automated Overdue Invoice Alerts and Follow-Ups When an invoice in Xero hits a defined overdue threshold, tray.ai checks the corresponding project record in Harvest and triggers automated alerts to the account manager, or sends a payment reminder directly to the client. Finance teams don't have to monitor aging reports manually. Teams can customize thresholds and escalation paths to match their collections process. - Reduce days sales outstanding with proactive payment reminders - Keep account managers informed about at-risk client accounts - Automate collections workflows without additional headcount ### Multi-Currency Project Billing Reconciliation For businesses working with international clients, tray.ai maps multi-currency invoices from Harvest to the correct currency settings and exchange rate records in Xero. This prevents mismatches in reporting and keeps you compliant with local accounting requirements. Finance teams can trust that international billing is handled consistently across both platforms. - Prevent currency mismatches in cross-border billing - Ensure accurate foreign exchange reporting in Xero - Support international client growth without added accounting complexity ## Templates ### Harvest Invoice to Xero Invoice Sync Automatically creates a fully itemized invoice in Xero whenever an invoice is generated or approved in Harvest, mapping client details, line items, hours, rates, and tax codes without manual intervention.

Without a mapping layer, invoice line items can land in the wrong account, causing misreported revenue and headaches at audit time. **How Tray.ai helps:** tray.ai's data transformation tools let teams define flexible mapping rules between Harvest task types and Xero account codes. Those mappings can be updated without code changes and apply consistently across every invoice sync. ### Avoiding Duplicate Clients and Invoices When finance and project teams create records independently in Xero and Harvest, duplicates pile up fast — double-billing risks, confused clients, and accounting reports that take hours to untangle. **How Tray.ai helps:** tray.ai checks for existing records in Xero before creating new contacts or invoices. Matching runs on email addresses, client names, and reference numbers, with conflict resolution rules that teams can configure to fit their process. ### Handling Multi-Currency Billing Accurately International clients may be invoiced in different currencies in Harvest, and those currency settings have to match precisely in Xero for accurate foreign exchange accounting and reporting. Mismatches produce incorrect revenue figures and compliance problems. **How Tray.ai helps:** tray.ai maps currency codes from Harvest invoices directly to the corresponding currency settings in Xero, so exchange rate handling and multi-currency reporting stay accurate. The platform also supports conditional logic for edge cases where currencies differ from the default. ### Keeping Sync Reliable Through API Rate Limits Both Harvest and Xero enforce API rate limits, which can cause sync failures during high-volume billing periods — like month-end — when large batches of invoices, time entries, and expense records all need processing at once. **How Tray.ai helps:** tray.ai handles rate limit management automatically using built-in retry logic, request throttling, and queue management. Every record gets processed reliably even during peak periods, so teams don't have to worry about failed syncs or missing invoices. ### Reconciling Historical Data During Initial Setup When first connecting Harvest and Xero, businesses often need to backfill historical invoices, client records, and expense data. Done manually, it's slow and error-prone. Done carelessly, it creates duplicates in both systems. **How Tray.ai helps:** tray.ai supports one-time historical data migration workflows scoped by date range, client, or project. Deduplication checks run throughout the backfill, and detailed logging gives teams a clear audit trail of every record created or updated during the initial sync. ## Learn more - Intelligent Integration: https://tray.ai/platform/intelligent-ipaas/ - Merlin Agent Builder: https://tray.ai/platform/merlin-agent-builder/ - Agent Gateway for MCP: https://tray.ai/platform/agent-gateway/ - Book a demo: https://tray.ai/contact/
