That APP is really great. Very light and fast. I was using ZOHO also and now we have more options!
You have to count that the perfect and light design theme has to be purchased separately from the main PRO edition. The cost is excellent but it is not clear that it is priced separately.
And one issue that has to be fixed is the VIEW option. Every item (customer, contact, invoice) is opening with EDIT mode, not with VIEW mode yet.
Support response is really great, and the script is a total business machine 🙂
