UPDATE: Tall Emu finally seem to have mostly fixed the sync after over a month of frustration and impacted business. It is fixed to the point where it is usable and not impacting the ability to run our business day to day. I still stand behind the comment on an all-in-one system. We have been with Tall Emu for almost 2 years and the majority of our issues have been linked to two systems trying to talk to each other, In our time we have had (and occasionally continue to have) data being duplicated, completely wiped out, being different in one system to the other (currently our balances are completely different in the two systems, we can only rely on MYOB as Tall Emu balances are just plain wrong for a number of our customers).
Tall Emu promised that we would save time on repetitive admin tasks with their platform. If we didn't factor the time in that we spend troubleshooting and fixing issue that Tall Emu causes, we would be very happy. But factoring in the countless hours, days, months and years that issues have taken our time to fix or wait for fixes we probably haven't saved any time, it has probably cost us time or at best left us in the same position we were in without spending thousands of dollars a year on an additional platform and the stress that has come along with it...
We continue to use Tall Emu and continue to work with some great people on the Tall Emu team in the hope that things will improve in the years ahead. As a system it isn't there yet, if you are looking for a CRM/ERP would recommend you hold off on signing up for Tall Emu or look for another system until things improve.
