This is a closing technique (I don't believe closing is a thing but hey) that can help usher a quicker timeline that isn't: Sign by the 30th to get a discount because.... Discounts!
I typically discuss how our implementation schedule flows in a wave pool motion
Everyone typically signs up end of month which takes away from our imp teams time and resources.
My company incentivizes people to sign on the 15th which also ensures that you're onboarding experience is better and more hands on.
Based on your timeline of X does this sound interesting to you?
60% of the time it works every-time lol
