What Xero data does Well pull into Pennylane?

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 Pennylane as supplier and customer invoices via email-in, with amount, VAT, and date pre-filled by Pennylane's OCR, with the Xero event ID preserved on the entry for audit.

Will every Xero record post to Pennylane automatically?

Not always. Within seconds of Xero 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 Pennylane email-in address and Pennylane 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.

How does Well prevent duplicates when posting Xero records to Pennylane?

Xero sends each event with a stable resource ID that Well tracks against the Pennylane ledger. Webhook replays (which Xero can issue for delivery retries) are recognised by ID and either skipped or used to update the existing Pennylane entry. Distinct records that look similar are caught by Well before posting, with the candidates surfaced in the review queue when confidence is ambiguous.

Can I customise which Xero fields are sent to Pennylane?

The default mapping covers every Xero field your Pennylane 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 Pennylane 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 Pennylane is left exactly as it stands.

What happens if I disconnect Xero or Pennylane?

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 you already reviewed and posted in Pennylane is Pennylane's own record and is untouched; Well never held a write credential to it. 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 Pennylane?

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, Well forwards the reconciled document to your Pennylane email-in address once it clears the matching threshold; Pennylane creates the draft record from it and you confirm and post it. Well holds no write credential to Pennylane. 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.
