What Pennylane data does Well pull into Xero?

Pennylane streams supplier and customer invoices, contacts, and VAT detail read over Pennylane's MCP server to Well over its MCP server. After Well resolves the counterparty and assigns a confidence score, the matched record posts to Xero as draft bills via email-in, with contact, dates, totals, line items, and tax type extracted by Hubdoc, with the Pennylane event ID preserved on the entry for audit.

How often does Pennylane data sync to Xero?

Pennylane 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 Xero within a confidence window: above 85% it posts, 55-85% queues for review, below 55% is refused.

Will every Pennylane record post to Xero automatically?

Not always. Within seconds of Pennylane firing the event, Well scores the record on field completeness, counterparty strength, and policy fit. Above the 85% default auto-link threshold Well forwards the reconciled document to your Xero email-in address and Xero drafts the record from it for you to confirm. Between 55% and 85% the record waits in the review queue with the alternative matches ranked. Below the 55% default review threshold the record is refused and the candidate list kept so you can pin the right entry by hand.

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

Pennylane carries the original transaction currency on every record and Xero natively ledgers in multiple currencies. Well preserves the original amount, applies your Xero chart-of-accounts conversion rules at posting time, and both the source and converted amounts ride on the document Well forwards to Xero, so the Xero entry you post keeps both sides of the trade.

Can I customise which Pennylane fields are sent to Xero?

The default mapping covers every Pennylane field your Xero chart of accounts accepts (counterparty, amount, currency, reference, tax). From the integration settings page you can override mappings field-by-field, attach computed values from your connected data (GL code, project tag, tax bucket), or ignore fields Xero does not need. Custom mappings are versioned and apply only to records reconciled after the change, so anything you have already reviewed and posted in Xero is left exactly as it stands.

How does Well authenticate with Pennylane and Xero?

Pennylane'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, Well forwards the reconciled document to your Xero email-in address once it clears the matching threshold; Xero creates the draft record from it and you confirm and post it. Well holds no write credential to Xero. Tokens are encrypted at rest and in transit under TLS 1.3. Pennylane hosts in the EU and Xero hosts outside the EU; Well processes records per the storage region configured for your workspace.

Why this pair

Pennylane is the French SMB ledger; Xero is the international one.

Groups that keep their French entity on Pennylane and an overseas entity on Xero have to keep the two sets of books speaking to each other in different currencies and tax regimes. Connecting Pennylane to Xero through Well reads Pennylane invoices and contacts via Well's OAuth-proxy MCP server, matches each against the Xero contact and bill list with the EUR amount carried on the document, and forwards the matched PDF to Xero's email-in. Hubdoc creates the draft bill with VAT and totals extracted; your team confirms the Xero tracking category and tax rate for the right entity.
