No, I didn't check the option to balance credits. None of our clients have any credit, we don't use credits, so I thought it wasn't necessary. I have the latest WHMCS version, 8.12.1, and the latest Blesta version, 5.11.2. There are a few open invoices, but most are closed. I will restore a backup from before the import and run the import again with the balance credits ON. Thanks.
