Financial errors result in an overpayment or underpayment to the client.
Non-financial errors, on the other hand, cannot be directly demonstrated to result in an overpayment or underpayment. For example, an issue of a supplementary benefit for which the client is not eligible is a financial error - it results directly in an overpayment. If, however, the file does not contain verification for the client's rent, then a non-financial error may have occurred. If the client is misreporting his rent, intentionally or not, this error also results in an overpayment. But, it may also be that the rent verification agrees with the amount on file, so no overpayment results.
