What Xero data does Well pull into Bill.com?

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 Bill.com as bills via email-in inbox, with vendor, invoice number, amount, and due date populated by Bill.com's IVA OCR, with the Xero event ID preserved on the entry for audit.

Will every Xero record post to Bill.com 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 Bill.com email-in address and Bill.com 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 match Xero records to entries in Bill.com?

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

What happens to historical Xero data when I first connect to Bill.com?

Xero exposes seven years of accounting history through its API on a connected account. The window Well actually pulls is configurable from the integration settings page; each record is matched against your existing Bill.com ledger, and re-running the backfill is safe because Well tracks the Xero record IDs and updates existing Bill.com entries instead of duplicating them.

Does Well handle multi-currency records between Xero and Bill.com?

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

How does Well authenticate with Xero and Bill.com?

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 Bill.com email-in address once it clears the matching threshold; Bill.com creates the draft record from it and you confirm and post it. Well holds no write credential to Bill.com. Tokens are encrypted in transit under TLS 1.3. Anything Well holds between Xero and Bill.com is encrypted at rest and handled in line with GDPR.

The Bill.

Why this pair

Your Xero books already hold the companies, invoices, and documents behind your accounting, but moving one of those records into Bill.

com by hand loses the context around it. Well reads the companies, invoices, and documents from Xero, resolves each counterparty to a single company, and forwards the document to your Bill. com email-in address with the business identified. The bill that lands for approval carries a company Xero already knows, so your team is not re-creating a counterparty that exists in the ledger.

01Featured

Carry a resolved counterparty to Bill.com

Well reads a company and its invoice from Xero and forwards the document to Bill.com's email-in address with the counterparty resolved, so approvers see a business the ledger knows.

Reuse the company Xero already holds

Well matches the Xero counterparty to a single company before delivery, so Bill.com does not create a duplicate of a business already in the books.

Keep the document and company together

Each Xero invoice or document reaches Bill.com with its resolved company attached, so the bill names the counterparty without a lookup.

Trace a bill back to the ledger

The Xero record Well resolved stays linked to the Bill.com document, so each bill points back to its ledger entry.
