In our business scenario we need to calculate the tax based on customer account instead of invoice account, so we "disabled the standard feature calculate the GST based on invoice account".

After disabling this feature the tax calculation happens based on customer account now, but other than tax the number sequence and credit limit logics are works based on invoice account in the sales order, so we request to add additional feature to consider customer account in all perspective while processing sales process, only transaction needs to be posted in invoice account.
