Query with sum but reference a value from the same calculation in a different column

I have two tables, Table A being:

and Table B:

I need a query to generate a table with the following columns:

1. Order No - unique
2. Total Amount - the sum of all the amount assigned to a particular order from Table A
3. Customer Name - customer name from Table B
4. Base Amount - the "amount" with "feetype" of "baseprice" from Table A

So far I've managed to generate columns 1 to 3 with the following query:

SELECT
    c.customer, a.orderNo, Sum(a.amount) AS [total]
FROM 
    a
INNER JOIN 
    (SELECT DISTINCT orderNo, customer 
     FROM table b) AS c ON a.orderNo = c.orderNo
GROUP BY 
    c.customer, a.orderNo;

But what I need is the following table

For MS Access you need to use something like this:

SELECT a.orderNo,
       b.customer,
       SUM(IIF(a.feetype = 'baseprice', a.amount, 0)) AS baseprice,
       SUM(a.amount) AS Total
FROM (TableA AS a
INNER JOIN (
    SELECT DISTINCT orderNo, customer 
    FROM TableB
) b ON a.orderNo = b.orderNo)
GROUP BY a.orderNo, b.customer;

The idea is similar to @Ergest Basha's solution but uses IIF(,,) instead of CASE WHEN and I prefer SELECT DISTINCT to SELECT MAX()
