Known issue: Payments Basis GST Calculation flawed by receipt/refund allocation

The following issue has been identified and subsequently replicated by MYOB Support in EXO Business versions 8.5.1 to 8.6.0.

Before upgrading your clients please take into consideration the following issues especially if the site has specific requirements in these areas.

As always we recommend that thorough testing in a non-live environment is undertaken before commencing an upgrade.


Support has confirmed that in Payments Basis GST the Calculation appears to be flawed in receipt/refund allocation results.

When a reversal is done, a new payment line should be created in the period that it is reversed in. This leaves a visible trail as well as showing in the GST return correctly as a positive in the original payment period and a negative in the reversal payment period.

This function is not officially supported by MYOB.


Manual reconciliation and journaling.
