# FAQ: Why do I get the warning "Number of fulfillments must be must be between 2 and 100"

Articles on: [SubBox](/en/category/subbox-mhmdp9/)

This warning will show when you enter a value less than 2 in the Number of fulfillments box with Prepaid or Prepaid (auto renew) plan types. For these plans, the Number of fulfillments is required more than 1 because the subscribers will be charged upfront

Here's an example to help you understand these plan better:  
If your subscriber buys a product (the price is $5) that has a Prepaid plan with Fulfillment frequency is every 2 days, Number or fulfillment (times) is 10, and the discount is $2, they will be charge $48 ($5 x 10 - $2 ). And then you will have an order that will be posted on your Shopify order's section with 10 fulfillments, you will need to fulfill them by yourself on your Shopify admin.
