multiple prefix for invoicing( cash bill and bank receipt bill)

sir,
      we have started the zoho books billing recently with test in standard plan.but unfortunately we are facing a problem in invoicing i.e two prefix bills .
one for cash bills and other from the bank receipt (credit billing ).
Is this option is available in zoho books. if so kindly suggest the solution at the earliest as to start up our billing .
