I GIVE THE DETAILS BELOW. SO BID WITH YOUR PRICE. ONLY BID IF YOU ARE ABLE TO DO IT.
CUSTOMIZE DELIVERY FEE
In the backend, if I Enable Charge per KM , the delivery fee will calculate : Base Delivery
Fee + Delivery Fee (per KM).
I want to customize like this. If I enable Charge per KM:
If Base delivery Fee higher than delivery fee (per KM), then use Base Delivery Fee.
If Delivery Fee (per KM) is higher than Base delivery Fee, than use Delivery Fee (Per KM).


FEES FEATURE WORK ON TOPUP
I can add fees to topup. Everytime user topup to their wallet, there will have fees that I
charge with. In other word is, Everytime user make any transaction using payment
gateway, there will be fees/ charge.


PRODUCT SERVICE PRICE
In the app/ system, vendor able to upload product by themselves. And now, let say,
I set Admin Commission 10%. And the vendor upload a product/ services and they set
the price 100$.
The price of the product/service the user will see in the app : 100$
Vendor Profit/ get : 100$ - 10% = 90$.
Admin get : 10% x 100 = 10$
What I want is (Based on the example above), let say I set Admin Comission 10%. And the
vendor upload a product/ services and they set the price 100$.
The price of the product/service the user will see in the app : 110$
Vendor Profit/ get : 100$
