In Acumatica, setting up the Check Payment Method is what tells the system how to handle vendor payments made by check. To do this, you go to the Payment Methods (CA204000) screen. First Start by defining the desired configuration for Accounts Payable, then link the payment method to the required cash account to ensure payments are drawn from the correct source. Next, assign the defined remittance report by default from the system: the stub report (AP641000) , you can also select the report developed using custom requirement for the primary check stub, and the additional remittance report (AP642000) to handle overflow when multiple invoices exceed the available stub space available beneath and above of check alignment. Once configured, Acumatica automatically prints both the check and complete remittance details each time you issue a payment, providing vendors with a detailed breakdown of paid invoices.
When processing vendor payments, many organizations perform ‘Process Payments’ using ‘Print Check’ functionality available with button with remittance details to clearly communicate which invoices are being paid. The check stub gives a quick summary, but when paying several invoices, there’s not enough space to list all the details on one line. That’s why a remittance report is important—it helps make sure the vendors get a full breakdown of the payment.

Acumatica streamlines this procedure by producing two reports automatically in the browser you are running the procedure of application for vendor payment. The Additional Remittance Report (AP642000) and the Check Stub Report (AP641000), if necessary. When combined, these reports guarantee that vendors receive a thorough list of all the invoices covered by the payment in addition to the check. This lessens problems with payment reconciliation and enhances vendor communication.
