aking  payments  efficiently,
cost-effectively  and  securely  is
pivotal  to  every  well-managed
finance  function.  Many  of  the  discus-
sions  on  payments  in  banks’  brochures
and  media  articles  surround  payments
processing,  particularly  straight-
through-processing,  security  and  bank
connectivity. These  issues  are, of course,
very  important  in  achieving  a  best-in-
class  payments  operation.  However,  in
addition  to  processing,  managing
payments  is  also  a  strategic  element  of
working  capital  to  ensure  that  the
company  is  able  to  take  advantage  of
early  payment  discounts  offered  by
suppliers  where  these  are  beneficial,
manage  FX  risk  created  by  foreign
currency  payment  obligations  and  time
payments  with  cash  inflows  to  avoid
liquidity  issues.    Furthermore,  the  cash
management  organisation  needs  to  be
structured  to  minimize  the  number  of
cross-border  payments  to  manage
payment costs.

Company  A  on  the  left  and  the  supplier
on  the  right,  the  purchase-to-pay
process  mirrors  the  order-to-cash
process,  typically  including  the
following steps (and challenges):
A. Company A receives the invoice from
the supplier and needs to reconcile
these against the order details before
authorisation and payment. This is
time-consuming if the original
purchase order number is not shown
on the invoice.
B. The company may wish to query the
invoice and again, the better aligned
the information between itself and the
supplier, the quicker this is to resolve.
C. Once approved, which may need to be
done by one or more business
managers, the payment can be
processed. This can be an involved
process internally, particularly in the
case of multiple payment origination
systems, large numbers of “one off”
supplier payments when supplier bank
account instructions need to be set up
and approved, if there are frequent
changes to payments or if a variety of
