AutoEntry

Is anyone using AutoEntry and willing to share their experience?  We are currently in the trial basis and seeing if this will be beneficial or not.  Looking for any feedback on the functionality (good, bad and the ugly), support, cost, etc.

Also, I am experiencing some challenges with equal payment invoices and the GST.  The GST is based on the actual expense which can vary from month to month but the amount billed is the equal payment.  For example the equal payment amount could be $100 (including taxes) but the actual cost of service (say it was electrical) for a month is $210 (200 + 10 GST).  Autoentry keeps picking up the $210 and not the $100.  I need AutoEntry to pick up in this case $90.00 base + $10.00 GST = $100 to balance to the equal monthly pmt. 

Any experience or ideas?
