Troubleshooting Minox debtor and creditor synchronization

Troubleshooting guide for Minox sync errors in Paragon. Fix missing debtor/creditor IDs and resolve VAT or IBAN validation blockers.

If your customers or vendors are not syncing correctly between Paragon and Minox Online, it is often due to strict validation rules. Before deep-diving into settings, try logging out of Paragon and logging back in to refresh your session.

Missing ID numbers in Paragon

If a customer or vendor does not receive a debtor or creditor number after saving, it means the synchronization to Minox was blocked. Minox performs a real-time validation of specific fields before it allows a new record to be created.

Check the following fields for errors:

  • VAT Number: Minox verifies if the identifier is structurally valid.

  • IBAN: Ensure the bank account follows international formatting rules.

  • Currency Code: Must be a valid, recognized code.

  • Country: Ensure the country is correctly assigned.

How to verify the error: Look at the Last sent to Minox and Customer Minox Transmission Status fields in Paragon. If the sync failed, the status field will display the specific error message, such as: "The VAT identifier is not valid."

ID exists in Paragon but not in Minox

In some cases, Paragon successfully assigns a number, but the communication with Minox is interrupted. To "force" a resync, follow these steps:

  1. Open the customer or vendor record in Paragon and click edit.

  2. Add a - (minus sign) in front of the customer/vendor number (e.g., -10001).

  3. Click save.

  4. Check Minox Online to see if the debtor/creditor has appeared.

  5. If successful, return to Paragon and remove the minus sign from the number.

Manual synchronization workaround

If the steps above do not work, you may need to establish the link manually:

  1. In Paragon, keep the minus sign in front of the ID number.

  2. Log in to Minox Online and manually create a new debtor/creditor.

  3. Use the exact ID number assigned by Paragon.

  4. Enter only the name of the company and click save.

  5. Return to Paragon, ensure all mandatory fields are correct, and click save again to push the remaining data.

  6. Once the sync is confirmed, remove the minus sign from the ID in Paragon.

Note: If a customer or vendor is created in Paragon but not yet activated, they will still sync to Minox but will be marked as "Blocked" (Geblokkeerd) until activated in Paragon.
