Difficulties with GST return following 'upgrade' to MYOB Business

Hi there

I am filing our first GST return following our 'upgrade' to MYOB Business from MYOB Essentials.

There are two issues:

1. I can get right through the process of completing the return but when I click 'File' to file with IRD, nothing happens. There is no message of any kind.

2. There are small differences (a few cents) in the tax collected/paid between the GST report and the GST return. This is annoying when both are generated from MYOB so the numbers should be the same. The total sales and income and the total purchases and expenses are the same in both reports.

I'd appreciate any assistance you can provide.

Many thanks

Pam
