Batch multiple transactions from one customer into a single charge
You can batch multiple transactions from a single customer together to avoid paying the Stripe fee on each charge. To do this, you first need to save the customer’s payment information. Then you can either:
Bundle the payments locally and create a charge automatically through your own system,
Subscribe your customer to a $0/month plan and create an invoice item for each small payment. By default, Stripe will pay the invoice automatically with each billing cycle.
