Initial Sync
Once you’ve created your Upflow account, named it, and selected your timezone, click Connect under Pennylane, and authorize access to your Pennylane account. Your data will then begin syncing. After the initial synchronization, Upflow performs incremental syncs every 10 minutes. These syncs only process supported data creations or updates to ensure data accuracy and eliminate discrepancies.What data is synced to Upflow

Credit notes
Credit notes imported to Upflow
Note: Credit notes must be visible in the “Management” section of Pennylane to be imported. Credit notes from Pennylane are imported under the following conditions:- Credit notes with status: credit_note, Overdue, Upcoming, Cancelled, Partially Cancelled, or Partially Cancelled Draft
- Credit notes marked as paid with “Paid” status AND having linked invoices
- Credit notes marked as paid with “Cancelled” status AND having no linked invoices
Credit notes not imported to Upflow
- Archived, Draft, or Incomplete status → These don’t impact customer balance
- Marked as paid with “Cancelled” status AND having linked invoices → These are manually created accounting entries, not real credit notes. Importing them would cause incorrect balances and duplicates
- Marked as paid and unreconciled (without linked invoices) → These are not properly reconciled and would create incorrect unapplied amounts in Upflow.
