Transfer pricing-query on payment to be received from abroad

Hi,

We are 1 STP unit & monthly we bill to our client "A" in USA. We got 1 more client "B" in USA itself, but this client cannot wire the funds to us (having some internal issues). They suggested that if B can pay cheque to A & in turn A will transfer us the funds. Will it be OK ?

How this will be settled in Bank ? is it ok under Transfer Pricing & FEMA ?

Please let me know your suggestions

Regards
