Well Ihave Dynamics SL 6.5 but this version does not include any tax reports for Mexico like IETU or IVA cobrado or DIOT and others, all this reports are necesary. We had to pay some one to made this reports.
The last year we start a migration process to Dynamics SL 7 we found that those reports, that we have paid for didn't work any more and Dynamics SL 7 didn't have it too, so we stop the migration and we are still in dynamics SL 6.5. I wonder if Dynamics SL 2011 have those kind of reports.
In Mexico you can find smaller ERP products that include it, like Contpaq (http://www.contpaqi.com/) or Aspel (http://www.aspel.com.mx).
