I offer memberships individually and as part of a B2B plan. Some memberships have a different first price, so I do not want to offer a low volume of them on the tiered plan. That means to manage my pricing, I might need to sell a minimum of 5 units instead of letting people circumvent the different first price.
As an example, I might sell my gold plan for 100 the first month, then 20 ongoing because they immediately access a load of downloadable content. I want to sell the tiered membership plan starting at $150/month for 10 users. I would have to set it at $15 per user with the current system, so a person could skip the initiation fee that way.
So, please allow us to set the minimum quantity on a tiered membership plan.
