NACHA rules on stop payments for non-consumer accounts say (Operating Rules subsection 3.7.2, 2016 edition):
An RDFI must honor a stop payment order regarding any debit Entry initiated or to be initiated to a Non-Consumer Account that is provided by a Receiver at such time and in such manner as to allow the RDFI a reasonable opportunity to act upon the stop payment order prior to acting on the debit Entry. The RDFI must comply with a verbal stop payment order only for a period of fourteen calendar days unless the order is confirmed in writing within that fourteen-day period.
Subsection 188.8.131.52 offers the following on the effective period for such stop orders:
A written stop payment order regarding any debit Entry initiated or to be initiated to a Non-Consumer Account will remain in effect until the earliest of:
(a) the withdrawal of the stop payment order by the Receiver;
(b) the return of the debit Entry; or,
(c) six months from the date of the stop payment order, unless it is renewed in writing.
