In some examples, a service provider may provide a payroll service and a payment processing service to businesses. For instance, with authorization from the employer, the service provider may withhold a percentage of funds received as sales revenue through the payment service. For example, the service provider may withhold a percentage of sales revenue each day to be used to pay at least a portion of the payroll payments paid to employees of the employer. Alternatively, the service provider may determine an amount of payroll payments currently due to be paid on a given day, and may deduct at least a portion of this amount from the sales revenue of the employer for that day. As another alternative, the service provider may make payroll payments in advance, and may withhold a percentage of the employer's daily sales revenue until the cash advance is paid back.
