Database Question

Hello,
I am building an ecommerce app, and the idea behind it is that After successful payment by the customer, i want all items present in the customer cart to automatically create in another collection of the database, so that the admins can only have access to paid items of the each user. The issue am facing now is that it is only the last item that is showing in the database collection. which means if a customer orders for 5 different items, it is the last chosen item that is shown in database after payment. Please kindly help me out if you have similar experience and it has been solved

Can we see a setup of your app through some screenshots or from a video?
