When Trello and Xero operate independently, project managers often face the challenge of tracking billable hours accurately. For example, if a team member updates a task in Trello with time spent, this information does not automatically reflect in Xero. As a result, the finance team must manually input this data into Xero, leading to potential errors in invoicing. This manual entry wastes valuable time and can result in discrepancies between project budgets and actual expenses.

Top Ways to Automate Trello & Xero

  • Automated Expense Tracking: Seamlessly sync expenses from Trello cards to Xero, ensuring that all project-related costs are accurately recorded in real-time, eliminating manual entry and reducing the risk of errors.
  • Instant Invoicing: Automatically generate invoices in Xero based on completed tasks in Trello, streamlining the billing process and improving cash flow by ensuring timely invoicing.
  • Comprehensive Financial Reporting: Integrate project data from Trello with financial metrics in Xero to create holistic reports, providing insights that enhance strategic decision-making and financial oversight.

How to Build the Trello → Xero Sync

  1. In Trello, create a webhook that listens for changes to cards in the desired board. Use the endpoint: POST /1/webhooks to set this up.
  2. Configure the webhook to trigger on 'updateCard' events, ensuring you capture relevant fields such as card.id, card.name, and card.customFieldItems.
  3. In your server-side application, listen for incoming webhook payloads from Trello. Extract the time tracking data from the customFieldItems array.
  4. Once you have the necessary data, format it according to Xero’s API requirements. Prepare a POST request to the Xero API endpoint: POST /api.xro/2.0/Timesheets.
  5. Include the extracted data in the request body, ensuring to map Trello fields to Xero fields accurately, such as card.name to Timesheet.Description and time spent to Timesheet.Hours.
  6. Send the request to Xero and handle the response to confirm successful insertion or log any errors for troubleshooting.

Developer Warnings & API Gotchas

  • Ensure that the Trello card's custom field for time tracking is consistently filled out; otherwise, the Xero API will reject the request due to missing required fields.
  • Be cautious with time zone differences when sending time entries to Xero; if Trello's time is in UTC and Xero expects local time, this could lead to incorrect billing hours.
  • When mapping Trello card IDs to Xero timesheet entries, ensure that IDs are unique and do not conflict with existing entries to avoid overwriting data.
