MultiPOS single cash out

I am trying to solve a problem that there is store where bill is made on many places but is received at only one place by cashier how to solve this ?

Can only be done through Sales Invoice. Use Is POS method. This method is applied in restaurant where order is accepted in one POS but payment is collected in another. In retail it’s pure cash and carry

POS will not make invoice without payment.

Yes the problem I am trying to solve is of cash and carry story but now the issue is filling an invoice is length process the POS entry was quite simple if invoice from multiple places is collected then how the payment is to be collected at one place
