SELECT cost_net,b.authname AS b_authname, i.authname AS i_authname
FROM bill b INNER JOIN invoices i USING(invoice)
WHERE i.affid = 654248 AND b.desctype = 0 AND i.commpaid = 0;

Now, i think you probably want to have invoice indexed on both sides of the equation, BUT since mysql can only use one index per table I suggest you have an index on i (invoice, affid) and b (invoice)

I don't know how your tables look with data in them or your other queries, but you should probably have less indexes and more indexes that involve more than one column.
