Confirming Check Numbers
When the check numbering page is displayed as part of a payment run, check numbers are automatically allocated to vendors starting from the next available check number in the active range. See About Check Ranges and Numbers for more information.
If all the checks in the list have been created successfully, either by printing or writing manually, click Confirm & Pay to post and match the payment proposal.
However, there are occasions when something goes wrong and you must take some action before clicking Confirm & Pay again. Some examples are described in Adjusting Check Numbers.
