A batch payout is a group of outgoing payments submitted together and processed as a single job, a form of bulk (batch) payment in which the payer is a platform or business and the recipients are sellers, workers, customers or suppliers. The term is common among payment providers, whose products let a client upload a spreadsheet or send one request containing hundreds or thousands of payout instructions.
The provider validates each line, checks that the client's balance covers the total, debits it once and then sends the individual payments over whichever rail suits each recipient. In the United States that is often an ACH batch; elsewhere it may be a local bank transfer scheme, a card push or a wallet credit. Results come back per item, so a batch can partly succeed, and failed lines are returned to the balance for correction.
"Batch payout" emphasizes the grouping and the submission method, while mass payout emphasizes scale and geographic reach; in practice the two overlap. Batches are submitted through a dashboard, by batch file processing or through a payout API. The main entry covers file formats, cut-off times, approval controls and reconciliation.
