Hello, @Abraham_Buching ,
I suggest to you Delivery Date Manager which perfectly fulfills your requirement, location & inventory. Delivery date manager is also compatible with zipcode validator so you can check the place where delivery is available and also check the product stock for that particular place.
Show your customers the estimated delivery time or day while entering the pin code in AppJetty Zip Code Validator. Increase your chance of having more customers by showing them the correct time and days it will take to deliver the product.
