@Kman is it dynamics 365 BC or F&O ? We had 5 hour demo sessions with oracle Netsuite consultant at Netsuite own head office in Dubai. I really like the ERP and how powerful the custom workflow , forms , and fields. I was smiling the entire time. But I have question if the system has any slowdown or congestions as the demo has hiccups with constantly waiting for screens to load, like 5 seconds to load a page sometimes.

D365 is Finance and Operations (includes mfg, warehousing etc) Netsuite has good uptime and no congestion that I'm aware of. They will put your business on the right sized server. I haven't heard of speed issues. The test environments they give a demo out of can be slow sometimes. Ask them for references in local market that use Netsuite. And then call them and ask these questions.

Thank @Kman
