Already I have built many simple to complex level e commerce system, quite similar to that.
1. Price calculator: User will choice product, select quantity of product, type of product & this system will automatically calculate the total price
-Please confirm me, in case of apply coupon code, will the system be able to adjust total price on this case?
-Also let me know, in case of discount percentage, will the system adjust price ?
-Vat % be calculated with the system?
-One more thing, will the delivery charge calculation be done through this system?
2. Stock Control: Just need to enter the date of inquiry, I mean in which date, sales details required & the system will provide the list of all sales & all payment info in a list view.
-I need to know whether the list be exportable or not?
-Whether the list is printable or not?
-Like the same, whether admin be able to bulk import of products through CSV or XLSX mode?
3. Invoices management: The system will produce printable invoices automatically, no need to make manually.
Invoices will mention, type of payment method, I mean payment by credit card/debit card or any other. Also it mention whether the customer make full payment or half payment or any other. In case of due payment, the due amount will be automatically forwarded wit the next bill.
4. User's controller: Different log in panel for various type of users.
5. I need a detail discussion on design section. I can start mock up designing through screen sharing as well.
