A wholesale lockbox is an efficient tool for turning customer payments
made by cheque into usable funds. Your customers mail their cheques to
strategically located post office boxes across Canada. They collect
and process the cheques, then deposit the funds directly to your
designated business account on the same business day allowing you
faster access to your cash. Cheques received after hours will be
deposited to your account on the next business day.
