ACH payroll: What it is, how it works & its benefits

Looking for a faster, more secure method of paying employees?

Direct deposit is a cost-effective and secure way of paying employees. But what makes this modern convenience possible for payroll and banking? The electronic transfer system known as the Automated Clearing House (ACH) Network.

What is the ACH Network?

The ACH Network allows companies, government agencies and individuals to electronically transfer money between bank accounts. Unlike other payment networks that can only do one or the other, it can push and pull funds. Same-day and future-dated transactions are both available.

What is an ACH payment?

There are many types of online payments possible through the ACH network, but those most relevant to employers managing payroll include the following deposits:

  • Wages and salaries
  • Travel and expense reimbursements
  • Disbursements from retirement savings plans
  • Dividend and interest payments

ACH transaction categories

ACH transactions fall into one of the following categories:

  • ACH credits – Funds are pushed from the account of the transaction originator to the account of the receiver.
  • ACH debits – Funds are pulled from the receiver’s account and sent to the originator’s account.
  • Entries – Depending on the receiver’s account type, an ACH entry can either be a consumer payment or a non-consumer payment.
  • Account validation – Validations verify that an account is open and accepting transactions.
  • Prenotification – ACH entries with no monetary value may be issued before the first live entry to validate an account.

How to use the ACH payment method for payroll

In most states, employees must agree to direct deposit before an employer can begin using ACH payments for payroll. Employees must also provide their employers with the following information:

  • Account type (checking or savings)
  • Bank name
  • Routing number (ABA/transit number)
  • Bank account number
  • Amount or percentage to be deposited each pay period

Employers give these details to their payroll service provider, who then processes the ACH payments on their behalf. ADP’s full-service payroll includes the setup and management of ACH payments.

The benefits of ACH payroll payment processing

Using ACH payments for payroll offers employers the following advantages:

  • Direct deposit is usually cheaper than the cost of printing and mailing checks.
  • Employees appreciate the speed and convenience of direct deposit.
  • Electronic payment is more secure than paychecks, which can be lost or stolen.

The drawbacks of ACH payroll payment processing

The benefits of using ACH payments when running payroll usually outweigh the cons, of which there are a few:

  • Transactions can take one to three days to process, though same-day payments may be available.
  • Some financial institutions prohibit international ACH payments, which may require wire transfers.
  • There are daily cutoff times, which, if missed, can delay transactions.
  • Banks may have a daily or monthly limit on how much money can be transferred.

The process of making ACH payments

ACH payments for payroll generally work as follows:

  1. After receiving authorization via a signed direct deposit form and all relevant banking information from the employee (receiver), the employer (originator) may initiate a transaction.
  2. The originating depository financial institution (ODFI) or bank receives payment instructions from the employer and sends ACH entries to the ACH operator.
  3. The ACH operator, a central clearing facility that performs settlement functions for financial institutions, forwards the ACH entries to the employee’s bank.
  4. The receiving depository financial institution (RDFI) or bank posts the ACH entries to the employee’s account or pay card.
  5. The employer’s account is debited, and the employee’s account is credited.

These steps are typically not necessary for businesses working with a payroll provider like ADP, which handles all ACH transactions on the employer's behalf

Frequently asked questions about ACH payroll

How long does an ACH deposit take?

The speed of ACH payments can depend on the sender. For example, ACH payments can be processed within a few hours on the same business day. Alternatively, payments can be scheduled for the following day or up to two business days if the sender chooses.

Generally, employees who agree to direct deposit have access to their wages by 9:00 am on the scheduled payday. In some cases, the money may even be available before payday if the bank or credit union advances their own funds before settlement occurs. However, payments are not settled on weekends and federal holidays.

How much do ACH payments cost?

ACH payments are usually free. However, some banks may charge a nominal fee for certain types of transactions.

What's the difference between ACH payments, wire transfers and EFT payments?

ACH payments and wire transfers are two types of electronic fund transfers (EFT). ACH payments are limited to domestic transactions, are generally free and may take one to three business days to process. Wire transfers, in contrast, can be used for international transactions, albeit with fees, and are usually processed within the same business day.

Are there any penalty fees with ACH payments?

Overdrafting an account to make an ACH payment or exceeding the number of transactions permissible per month, if any, may result in penalty fees.

Are ACH transactions secure?

ACH transactions are secure due to stringent data protection requirements, such as encryption and tokenization. These safeguards are mandated by Nacha, the governing body of the ACH Network, to render account numbers unreadable when stored electronically.

The network's design includes multiple layers of security through verified entities and robust fraud prevention measures aimed at mitigating risks like credit-push fraud​​. Additionally, ACH transactions adhere to comprehensive regulatory standards and guidelines issued by bodies, like FFIEC and NIST, ensuring their continuous security and efficiency​​.
