How Pennylane and Bill.com stay secure with Well

Well connects to Pennylane through its MCP server, which issues short-lived access tokens via Dynamic Client Registration. Well never holds a long-lived Pennylane secret; the server refreshes its own tokens on each session. Well processes records per the storage region configured for your workspace; only fields strictly required by the write surface are ferried across regions.

Frequently asked questions about Pennylane and Bill.com on Well

01How often does Pennylane data sync to Bill.com?
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 Bill.com within a confidence window: above 85% it posts, 55-85% queues for review, below 55% is refused.
02How does Well match Pennylane records to entries in Bill.com?
Well scores every candidate match between Pennylane 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.
03Does Well handle multi-currency records between Pennylane and Bill.com?
Pennylane 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.
04Can I customise which Pennylane fields are sent to Bill.com?
The default mapping connects each Pennylane record to the Bill.com bill shape (vendor, amount, due date, approval policy). Settings let you override the vendor source, swap default approvers, attach a different document on the bill, or pull GL codes from your connected data. Mapping versions are immutable for already-paid bills so audit traces stay intact.
05What happens if a Pennylane record fails to post to Bill.com?
When a record fails to post to Bill.com (validation rule, missing field, transient 5xx), Well retries automatically with backoff. Auth failures short-circuit the retry loop and notify the workspace owner; schema rejections are kept on the integration status page with a one-click retry-after-fix action pointing back at the original Pennylane record. Nothing silently drops.
06How does Well authenticate with Pennylane and Bill.com?
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 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 at rest and in transit under TLS 1.3. Pennylane hosts in the EU and Bill.com hosts outside the EU; Well processes records per the storage region configured for your workspace.
