Hi. We are looking for customization for our company accounts in Manager software. Is there any dedicated help/support contact number for the same.
No, there is not.
Welcome to the forum @Jabir,
The customizations available are simple and documented in the published guides.
However, tailoring a set of configurations/customization specific to your needs requires accounting knowledge, and IT experience with your other software – if any. And that is outside the scope of the services currently provided.
