What Cause Double Payment on Invoice in Accounts Payable?

Version: 7.x & up
Release Date: 07/23/2026

Q - Can you help explain why something happened? We have a double payment on an invoice.  In this example, we have a copy of the check# 77716, date 7/14, vendor# NEL01 and voucher# 38300. At the next check run on 7/21, a different check for the same vendor and same voucher# 38300 is printed again. We are unsure why or how this happen?

A - From my experience, the most situation that user forgot post prior check run (i.e. check # 77716, date 7/14/26, Vendor # NEL01). At next check run at 7/21, system will treat non-post check as VOIDED if same vendor (i.e. NEL01) repeat from previous non-post check list.

Generally speaking, vendor # NEL01 has non-post check from 7/14/26 (CHK #77716). System will void check # 77716 automatically if user proceed Payment  (voucher # 38300) again.

Suggestion and Make rule on AP payment
  1. Post Check immediately after printed - Do not sign check if you do not see it on "Check Posting Journal".
  2. Quickly check both check run if there are duplicated vendors (i.e. NEL01.)
