What Xero data does Well pull into Qonto?

Xero streams bills, contacts, tracking categories, and tax types read over Xero's MCP server to Well over its MCP server. After Well resolves the counterparty and assigns a confidence score, the matched record posts to Qonto as supplier invoice PDFs pushed via OAuth to /v2/supplier_invoices, with the Xero event ID preserved on the entry for audit.

How often does Xero data sync to Qonto?

Xero pushes events to Well over its MCP server, so most records land within seconds of the underlying action. Each event is matched immediately and reaches Qonto within a confidence window: above 85% it posts, 55-85% queues for review, below 55% is refused.

How does Well match Xero records to entries in Qonto?

Well scores every candidate match between Xero records and existing Qonto entries on counterparty name, amount, date proximity, currency, and reference. Above 85% the record links to the historical entry and Qonto updates; between 55% and 85% the candidates are queued for sign-off; below 55% the record stays open with the candidate list available.

Does Well handle multi-currency records between Xero and Qonto?

Xero carries the original transaction currency on every record and Qonto natively ledgers in multiple currencies. Well preserves the original amount, applies your Qonto chart-of-accounts conversion rules at posting time, and Well writes both the source and converted amounts onto the record it posts to Qonto, so the entry keeps both sides of the trade.

What happens if I disconnect Xero or Qonto?

Disconnecting Xero stops the flow at the source. Well asks the Xero MCP server to revoke the access token; Xero returns confirmation and stops streaming events the moment it is acknowledged. Anything Well already wrote to Qonto before the disconnect stays in Qonto; the connection only stops further writes. Records held for review in Well remain in the queue so you can finish them by hand. Reconnecting later resumes from the last successful sync, not from scratch.

How does Well authenticate with Xero and Qonto?

Xero's MCP server handles authorisation directly; Well receives an access token through Dynamic Client Registration and never sees raw user credentials. For the delivery side, once a record clears the matching threshold Well posts it directly to Qonto over the connected API; the credential is held per-workspace and never exchanged across tenants. Tokens are encrypted at rest and in transit under TLS 1.3. Qonto hosts in the EU and Xero hosts outside the EU; Well processes records per the storage region configured for your workspace.
