Laravel cashier + Stripe : creating a plan with quantity and decreasing prices

Hello everyone,

I'm whiling for one of my project to create a subscription system with Laravel Cashier and Stripe.

We will offer one plan to our users : 10€ / month for one location (they can add locations in the system) and for 75 followers.

What I want to do, is to make them pay more for locations : 2.5€ / locations / month for example, so this can be achieve with quantities ? But still, if the basic plan is at 10€ and I put 2 as a quantity, total price will be 20€ ?

Then price will be also based on their followers. 75 are included in the basic price. But then if they want more, they will also have to pay.

Example :

• 76-150 : + 4.95€ a month
• 151-250 : + 4.80€ a month etc ...

How can I handle that and make sure the customer will have to pay everything in one shot ?

Thanks in advance !
