Some clients have experienced issues with their Quickbooks account where customers fail to send over to the accounting package due to the length of the customer name.
Quickbooks online has this limit in their API and it's them that's sending us this message - we send the name to them and they reject it telling us it's too long. The actual limit is 25 characters, but because Commusoft send across the account number as well, we limit you to 18 characters. 25 characters isn't very long, and seems a little strange that they even have a limit. We recommend speaking to Quickbooks and seeing if it can be changed.
Unfortunately this is out of Commusoft's hands and rely's on Quickbooks API
