Sync Monday orders to Xero POs, invoices and bills

Tools

Make

Overview

A Make.com setup for a client creates Xero purchase orders, emails client invoices, and matches supplier invoice uploads to bills, flagging failures for attention.

Workflow

Suggested implementation: Use Make.com to create three scenarios triggered by Monday.com webhooks. When a Purchase Order item is marked 'Ready', the workflow finds or creates the supplier in Xero, generates a PO with line items, downloads the PDF to Monday, and creates a matching bill. A separate flow handles client invoices by reversing this process and emailing the invoice. Staff must manually correct items in Monday.com when failures occur, rather than debugging within Make.com.

Reported result

Actual outcomes are unknown as the source returned a 403 error and no verifiable production data is available. The original author claimed the flows were tested and running, with failures triggering a 'Needs Attention' status in Monday. To verify success, implement a measurable acceptance check: track the percentage of orders processed without manual intervention over a two-week pilot period.

Human role

Staff must correct items in Monday.com when failures occur, rather than debugging inside Make.com.

Limitations

Prerequisites include active accounts for Monday.com, Xero, and Make.com with appropriate API permissions. The system's autonomy relies on clean status-based retries in Monday; if statuses are inconsistent, automation fails. Integration uncertainty exists regarding Xero's rate limits and Monday's webhook reliability. Human approval is required for any financial data corrections in Xero. Proposed advice: Start with a low-volume pilot to validate error handling before scaling.

Try it

Act as an automation engineer. I need to build a Make.com scenario connecting Monday.com and Xero. Inputs: - Monday.com Board ID: [replaceable_board_id] - Xero Tenant ID: [replaceable_tenant_id] - Trigger Status: 'Ready' - Failure Status: 'Needs Attention' Steps: 1. Create a webhook trigger in Make for Monday.com when an item status changes to 'Ready'. 2. Add a module to search for the supplier in Xero by name; if not found, create a new contact. 3. Create a Purchase Order in Xero using the Monday item's line items. 4. Download the generated PO PDF from Xero and attach it to the Monday item. 5. Create a Bill in Xero linked to the PO. 6. Add error handling: If any step fails, update the Monday item status to 'Needs Attention' and add a comment with the error message. Deliverables: - A JSON export of the Make.com scenario. - A test log showing one successful run and one simulated failure. Quality Check: - Verify the PO number in Xero matches the reference in Monday. - Ensure the PDF is correctly attached. Safeguards: - Run a dry test with a dummy supplier and low-value PO first. - Do not connect to live financial data until the dry run is confirmed by a human supervisor. - If inputs are missing, ask for the specific Board ID and Tenant ID before proceeding.
