For example, with the free plan a provider can check that new software doesn't break SLAs only one per day. With the pro plan there is no limit. This is just one difference as an example

Hmm.. And is it expensive? I mean the premium plan. Cause looks like there are many benefits
Check their pricing table on the website, but there will be personal offers, depending on many factors, I believe

Perfect, will check it out shortly, thank you. Priority support may be an interesting addition to a premium package...
Yeah, and it is available for premium users

Sounds good, yep, I see it now in the pricelist table! Thank you for your help, sir, enjoy your day...
