Direct deposit is a really convenient way to get your employees paid. Whether you're using Standard or Advanced Payroll, you can pay employees directly through QuickBooks Online.
The standard direct deposit limit is $20,000. This cap is put in place to protect you from fraudulent activities, however you're able to increase your limit if you need to process larger amounts. For more information about direct deposit security limits, or to increase your limit, take a look at this article: Direct Deposit Security Limits. There's a link within this article where you can request an increase to your direct deposit limit. Keep an eye out for that in the first paragraph.
I'd be happy to answer any other questions you may have about direct deposit and QuickBooks Online.
