Dear Onsima,
I really appreciate how you care about this topic. The project with advanced fiber will be our model case for the future.
I read through the cases and I understood it that way:
In both cases a „supervision fee“ was billed. In your case ATSS will only do installation / assembling of our products. No employee of ATSS will teach the end customer how to install our products. And there will be no supervision.
If it is ok for you I would propose to contact our contact of PWC in Thailand who gave us the feedback. So we can be sure to do it correct for the future.
Best regards
Bettina
