Can I use 'Zahlung' here instead of 'Bezahlung'?
"Zahlung" doesn't work here. I can't explain it, sorry.
Can one say "Wie immer ist das Gehalt schlecht" ?
Wie gewöhnlich ist die Bezahlung schlecht – is it correct?
I thought so too...
Do you need a wie there?
Yes. It's the "as" in "as usual".
Warum nicht: "Vergütung"
Can "wie immer" go at the end?
I'd say yes.
Yes, that would be like saying "the payment is bad AS USUAL" if i understand sentence structure correctly, which in the sense of this sentence would make sense
It is accepted at the end
Koushik, Zahlung wurde soeben akzeptiert.
