Custom Shopify Store Development

1. Anyone visits the store can see an option to top up using digital products of various preset amounts 2. They must be logged in to purchase this digital products 3. Whenever wallet digital products are purchased, an equivalent or set amount must be automatically added to their store credit 4. Once store credit is automatically added to their account, a tag 'reseller' must be added to their account and so customers will able to access checkout page and place orders 5. As long as they have store credit balance, they can keep ordering 6. Once balance runs out, the tag 'reseller' must be automatically removed from their account and thus they should not able to access checkout page stopping them from making orders 7. In the checkout page custom fields must be added i.e., Reseller Name, Display Price to Customer(this amount will be collected from customer in case of COD orders), Is it a COD Order(yes, collect payment from customer. no, do NOT collect payment from customer) Note: Also confirm that if users can see the wallet balance on top of their page when they are logged in and if they can see their store credit transactions history page, like how a wallet history page will be seen.
