You only need to update the Shipping Address information with the Billing Address if the Shipping Address (Compound Field) has having blank value.
Hands on

trigger AccountTrigger on Account (before insert, before update) {
AccountTriggerDispatcher.dispatch(Trigger.operationType);
}
Dispatcher Class
public class AccountTriggerDispatcher {
public Static void dispatch(System.TriggerOperation operationType){
switch on operationType{
WHEN BEFORE_INSERT{
AccountTriggerHandler.beforeInsert(trigger.new);
}
WHEN BEFORE_UPDATE{
AccountTriggerHandler.beforeUpdate(trigger.new);
}
}
}
}
Handler Class
// Handler Class calls helper class
public with sharing class AccountTriggerHandler {
public Static void beforeInsert(ListaccountList){
AccountTriggerHelper.helperBeforeInsertUpdate(accountList);
}
public Static void beforeUpdate(ListaccountList){
AccountTriggerHelper.helperBeforeInsertUpdate(accountList);
}
}
Helper Class
public class AccountTriggerHelper {
public Static void helperBeforeInsertUpdate(ListaccountList){
for(Account acc : accountList){
if(acc.ShippingStreet == Null){
acc.ShippingStreet = acc.BillingStreet;
}
if(acc.ShippingCity == Null){
acc.ShippingCity = acc.BillingCity;
}
if(acc.ShippingState == Null){
acc.ShippingState = acc.BillingState;
}
if(acc.ShippingPostalCode == Null){
acc.ShippingPostalCode = acc.BillingPostalCode;
}
if(acc.ShippingCountry == Null){
acc.ShippingCountry = acc.BillingCountry;
}
}
}
}
