Error: INVLD ACCT - Response code(220)

Can anyone tell me what this error means? A user of our app is trying to purchase something, so we create an invoice, add an invoice item and then attempt to charge the invoice and see this message returned from the failed invoice attempt: “INVLD ACCT - Response code(220)”.

I thought there was a place that contained all IFS errors but couldn’t seem to find it anywhere in the forums or using Google. Any help is appreciated.

Can you give me the call parameters and Infusionsoft application instance that are generating the error?

I sent a private message with the details.
