Requesting politely

[Nimbuz]

Hi all,

I speak fairly good english (ofcourse its not my primary language) when its just about my work (Programming and Internet) but when its anything offtopic, I can't frame sentences too well.

So I recently had to request a client to pay my outstanding payment, I couldn't decide what to say, politely and in a business-tone:

- Can you please process my invoice today or sometime this week?
- Can you please clear off the outstanding today or sometime this week?
- Can you please send the payment today or sometime this week?

What would you say? Since I get into this situation frequently, I thought I'd better ask here and be sure whats the best and more polite way of request payment of a pending invoice.

Look forward to comments and advices.

How about this one...

Would you mind sending the payment today or sometime this week?
