Understanding ACH Transaction

The ACH network is the main electronic payment system in the US. It’s run by Nacha and used by most bank accounts. The ACH processes transactions between banks and credit unions using a batch system, with ACH processing times that vary depending on the type of transaction and the banks involved.

ACH transactions refer specifically to electronic money transfers between banks. The initiator a person, business, or government provides their bank with payment instructions. This bank forwards the instructions through the ACH network, which ensures the funds are securely delivered.

The National Automated Clearing House Association manages the network. The Withdrawal money is credited to the account in depositing. ACH transactions fall into two categories: credit and debit. In a credit transaction, the originator sends money to the receiver’s account, as in the case of an employer paying an employee. These are debit transactions that pull money from the originator, such as paying utility bills and mortgages.

Examples

Businesses use ACH to

  • pay bills,
  • Vendors,
  • employees, and
  • Customers

Mostly, because they are safe and cannot be stolen, making for quick payments and good cash flow.

To track an ACH transaction, you will need to compile all relevant information and documentation. That includes transaction details, account statements, and any records that indicate that you approved the transaction.

Gather information such as the date, time, amount, names of the sender and receiver, and reference or confirmation numbers. Obtain bank statements indicating account activity. If that transaction was approved, you’d collect documents such as contracts, invoices, or signed forms.

So, make sure you have contact information for your bank handy, including phone numbers and emails for customer support, and contact the sender or receiver of the transaction if necessary.

If you encounter any of these issues, it’s essential to understand what to do under such circumstances, whom to reach out to, and what steps to take.

Finding The ACH Trace Number

ACH trace numbers can be found in your online banking transaction details, or on your statements. Typically, there are two trace IDs one for the sender and the other for the receiver.

To help expedite transaction tracing and report back on any issues, many banks request you provide specific information like the date and amount of the transaction or the ACH trace number.

Source ID and Destination ID

In finance, there are two kinds of trace IDs: source and destination. You can trace source IDs on the day of the transaction, but you can only trace destination IDs after the money is in the recipient’s bank account. If you have a destination ID, give it to the customer and tell them to call their bank right away. The bank will handle it from there.

Contacting the Bank

If you are waiting to get paid, contact your bank with the ACH trace number. You may need to ask the person paying you for this number. If the person receiving the payment is waiting, they should reach out to their bank. Sometimes, just knowing the date and amount of the transaction is enough for the bank to trace it.
