Xero and JAGGAER integration

What moves between them

The main flow runs from JAGGAER into Xero. Vendor invoices and purchase orders created or updated in JAGGAER flow into Xero as invoices and bills, mapped to the appropriate Xero GL accounts and tracked against the correct contact record for the supplier. Supplier master data from JAGGAER is synced to Xero contacts so that each vendor in JAGGAER has a corresponding contact in Xero. The sync is scheduled based on your procurement close cycle, typically after JAGGAER invoices are approved. Data flows one way only; Xero is the source of truth for accounting records, and JAGGAER is the source of truth for procurement transactions.

How ml-connector handles it

ml-connector stores OAuth2 credentials for both systems encrypted and manages token refresh independently for each platform, since Xero tokens expire after 30 minutes while JAGGAER tokens follow a different cadence. For Xero, ml-connector includes the Xero-tenant-id header on every request and respects the 5 concurrent call and 60 per minute rate limits by queueing requests and backing off on 429 responses. For JAGGAER, ml-connector builds the full instance URL per customer from the stored endpoint and presents OAuth2 client credentials on every request. When posting invoices from JAGGAER into Xero, ml-connector maps JAGGAER GL accounts and vendor names to Xero accounts and contacts by exact name matching; mismatches are flagged and require manual review before posting. Invoices in Xero reference purchase orders where applicable, and payment terms flow from JAGGAER to Xero. The audit log captures every record synced, every API call, and every mapping decision so disputes can be replayed.

A real-world example

A mid-market manufacturing company runs JAGGAER for procurement and supplier management across dozens of vendors worldwide, and Xero for accounting and financial close. Before the integration, the accounts payable team received supplier invoices in JAGGAER, created a matching AP batch in a spreadsheet, and manually entered each invoice into Xero at month-end close, a process that introduced re-keying errors and delayed reconciliation. With JAGGAER and Xero connected, approved invoices flow into Xero automatically after they are matched in JAGGAER, mapped to the correct project or cost center, and the AP team can close the month faster with fewer data-entry errors.

What you can do

• •Sync vendor invoices and purchase orders from JAGGAER into Xero as invoices and bills with correct accounts and supplier contacts.
• •Map JAGGAER suppliers to Xero contacts and JAGGAER GL accounts to Xero accounts by name for accurate accounting records.
• •Manage OAuth2 token refresh for both Xero and JAGGAER independently, respecting each platform's expiry and rate limits.
• •Handle Xero's per-tenant routing via the Xero-tenant-id header and queue concurrent requests to stay within Xero's call limits.
• •Capture every invoice, purchase order, and account mapping in an audit trail so any record can be reviewed or replayed if a mismatch is found.

Questions

Which direction does data flow between Xero and JAGGAER?

The main flow is from JAGGAER into Xero. Vendor invoices, purchase orders, and supplier master data move from JAGGAER into Xero so that procurement transactions are reflected in accounting records. Xero is the source of truth for accounting, and JAGGAER is the source of truth for procurement; ml-connector does not write back to JAGGAER.

How does ml-connector handle Xero's per-tenant header and rate limits?

Every Xero API request requires the Xero-tenant-id header to target the correct organization, since Xero is multi-tenant. ml-connector includes this header on every call and respects Xero's 5 concurrent call and 60 per minute rate limits by queueing requests and waiting if needed. If Xero returns a 429 rate limit error, ml-connector backs off and retries.

What happens if a JAGGAER supplier or account cannot be found in Xero?

ml-connector matches suppliers by name and accounts by name; if an exact match is not found, the record is held in the audit log and flagged for review rather than posting with a wrong account. The mismatch must be resolved in Xero (create the missing supplier contact or account) before the invoice can be posted, so accounting records stay accurate.
