Resolve the counterparty for payment
Well reads a company and invoice from Xero and forwards the document to Melio's email-in address with the counterparty resolved, so the payer is clear.



Move Xero bills and contacts through Well and into Melio as bills, with the audit trail kept on every record.

The Xero integration connects Well to your accounting platform for bidirectional data flow.

The Melio connection delivers extracted bills into Melio through its Pay Bills email address.
When a bill in your Xero ledger needs paying through Melio, a bare name gives your team little to confirm who the counterparty is.
Well reads the companies, invoices, and documents from Xero, resolves each counterparty to a single company, and forwards the document to Melio's email-in address with the business identified. The bill that reaches Melio carries a company the ledger already holds, so your team is not guessing at who they are about to pay.




Well reads a company and invoice from Xero and forwards the document to Melio's email-in address with the counterparty resolved, so the payer is clear.

Melio's OCR resolves the vendor name from the PDF; banking details for the payment route are set up separately.

Well connects to Xero through its MCP server, which issues short-lived access tokens via Dynamic Client Registration. Well never holds a long-lived Xero secret; the server refreshes its own tokens on each session. Anything Well holds between Xero and Melio is encrypted at rest and handled in line with GDPR.
Read Xero records
Scoped to bills, contacts, tracking categories, and tax types read over Xero's MCP server. No access to anything else in your Xero account.
Deliver documents to your Melio inbox
Well forwards the extracted document to your Melio email-in address; Melio reads bills via email-in at @invoicesmelio.com, with vendor, amount, and due date populated by Smart Bill Capture from it and you review and post. No write credential to Melio is requested.
Modify or delete Xero records
Not granted. Xero is read-only on Well's side; the source of truth never moves.
Read other workspaces' data
Not granted. A session resolves only to the workspaces your account belongs to, and Well checks that membership before it returns any record.


Link both tools to Well so a Xero bill reaches Melio as a resolved counterparty document.
