What if I want to do this 14 month deal with multiple customers but they sign on at different times?

You can set that start/end date on each transaction or line of a transaction. You could also set a 14 month term on the revenue rule itself. More specifically the recognition timing is exclusive from the amount being billed, so if you are giving two months free with a discount item then set the rev rec start/end date like you would if there was no discount

Put a 2 in the Start Offset field of the Revenue Rule or Revenue Template, whichever you are using. I think that will get you what you need. I'm not a 606 rules expert by any means, but should you not record the revenue those two months? You're still providing the service, even if you're not charging for it. Might be worth an email to your auditors so you don't get dinged by them later.

There is a billing feature called Time-Based Pricing (under Enable > Transactions under Billing), see if you have it. HOWEVER, you provide services over 14 months, NOT over 12 months and you should recognized revenue over 14 months. what this feature does is delays billing, not rev rec

Hopefully didn't mislead with my response - I also meant that the amount should be recognized over period of services rendered, regardless of there being a 2 month discount in the amount billed.

no, @Alex K - we would never think of that! 🙂 . @devread - btw, that feature I mentioned belongs to SuiteBilling
