It doesn’t matter. Or at least — it shouldn’t.
Unless you are selling a true commodity — you are already well past the $5 a month or Free discretionary price points.
And you are well within the “stick it on my credit card” price point.
In SaaS, if you can close customers at $89/mo but not $98 … something is very odd here. Again, unless you are selling a commodity. Which is pretty uncommon in SaaS.
And even if you are … higher price often suggests more value.
So it may even be easier to sell at the higher price.
