How to make an ACH payment

An ACH payment is an electronic bank transfer processed through the Automated Clearing House network, which allows money to move directly between bank accounts without paper checks or wire transfers. Businesses commonly use them for payroll, vendor invoices, tax payments, and recurring subscriptions.

If you've ever needed to pay a supplier or move funds without paying high wire transfer fees, ACH is often the simpler, cheaper option. What follows covers exactly how to initiate one, what you'll need beforehand, and what to expect on processing timelines.

Before making an ACH payment: Why accuracy matters

Because ACH transactions move directly between bank accounts, entering incorrect banking details can lead to rejected payments or delays. Most banks and payment platforms verify account details before processing the transaction.

Preparing the right information ahead of time ensures that your ACH payment processes smoothly. It also helps you avoid common issues like insufficient funds or authorization errors.

Required recipient information

Before sending an ACH payment, you'll need basic banking information about the recipient:

• Recipient's full legal name or business name: Enter the recipient's full legal name or registered business name exactly as it appears on their bank account
• Bank account number: Provide the recipient's bank account number so the ACH network knows which account should receive the transferred funds
• Bank routing number (9-digit code): The routing number is a 9-digit code that identifies the recipient's financial institution and directs the ACH payment to the correct bank
• Account type (checking or savings): Select whether the funds should be deposited into a checking or savings account, since banks use this designation to route the transaction correctly
• Payment amount and purpose: Specify the exact amount you want to transfer and include a brief payment description, such as invoice number or service type, for recordkeeping

Sender requirements

You'll also need to meet several requirements on your end before initiating the transfer:

• Verified bank account with sufficient funds: Verify your bank account has enough available funds to cover the ACH payment and avoid rejected transactions
• Online banking access or payment platform account: You'll need access to your bank's online portal or a payment platform to initiate and manage the ACH transfer
• Authorization from account holder: If you're sending payments from a business account, make sure the authorized account holder has approved the transaction
• Understanding of daily or monthly transaction limits: Review your bank's ACH transfer limits so you know whether your payment falls within the allowed daily or monthly thresholds

Most banks require account verification before allowing ACH transfers. This may involve confirming micro-deposits or linking accounts through secure banking authentication.

Step-by-step guide to making an ACH payment

Making an ACH payment usually takes only a few minutes once your account is set up. The exact steps may vary slightly depending on whether you use a bank portal, accounting software, or payment platform. However, the basic process remains similar across institutions like Wells Fargo, Bank of America, or Chase.

Understanding the workflow helps reduce errors and ensures payments arrive on time.

Step 1: Choose your payment method

You can initiate ACH payments through several different platforms depending on how your business manages finances:

• Online banking portal: Most banks allow ACH transfers directly through their online banking interface. You log into your account, navigate to transfers or payments, and enter the recipient's banking information.
• Third-party payment processor: Payment processors such as Stripe or PayPal offer ACH payment capabilities within their payment platforms. These tools often support recurring payments, payment tracking, and automated reconciliation.
• Accounting software integration: Many accounting platforms connect directly to your bank account so you can send ACH payments from your financial dashboard. Automated bank reconciliation helps ensure payments match invoices and accounting records.
• Mobile banking app: Some banks also support ACH transfers through their mobile apps. These apps typically provide simplified interfaces for one-time payments or scheduling recurring transfers.

Step 2: Enter payment details

After selecting your payment platform, the next step is entering the recipient's payment information.

You'll typically complete the following steps:

• Navigate to the ACH or transfer section of your banking platform
• Input the recipient's routing and account numbers
• Confirm the recipient's name and account type
• Select the payment amount and transaction description

Most systems will ask you to double-check routing and account numbers before proceeding. This helps reduce errors that could cause rejected transactions.

Step 3: Verify and submit

Before finalizing the payment, your bank or payment processor will display a summary screen. This allows you to confirm that all transaction details are correct.

You should review the recipient's banking details, confirm the payment amount and scheduled date, and submit the transfer. Save your confirmation number.

Many systems also allow you to configure alerts. Email alerts notify you when a payment is processed. Mobile notifications confirm when funds settle in the recipient's account. Dashboard tracking shows payment status in real time.

These notifications help you track payments and respond quickly if something goes wrong.

ACH payment processing times and cutoffs

ACH transfers are processed in batches rather than individually. Banks collect payment instructions throughout the day and send them to the ACH network for clearing. Because of this batch processing system, ACH transfers usually take between one and three business days to complete.

ACH processing speed depends on several factors including cutoff times, the type of ACH transfer, and whether the payment qualifies for same-day processing.

Standard processing times

ACH payments generally follow one of several processing timelines.

Same-day ACH processing requires payments to be submitted before specific network deadlines. The ACH network operates three settlement windows each day.

According to NACHA rules and Federal Reserve ACH schedules, you must submit payment files before approximately 10:30 a.m., 2:45 p.m., or 4:45 p.m. Eastern Time to qualify for same-day settlement.

Cutoff times and deadlines

Most banks set internal cutoff times slightly earlier than network deadlines. This allows them to process and submit payment batches on time.

Common factors that influence ACH deadlines include:

• Bank-specific cutoff times
• Weekends and federal holidays
• International ACH processing timelines

International ACH differences

International ACH transactions (IATs) often take longer because they must comply with additional regulatory requirements and currency processing rules.

Many banks process international ACH transfers in 2–5 business days depending on the receiving institution.

ACH debit versus ACH credit payments

ACH transactions fall into two main categories: ACH credit and ACH debit. Understanding the difference helps you choose the right method for each payment scenario.

ACH credit (push payments)

With ACH credit payments, you initiate sending money from your account to another account.

Common examples include:

• Payroll deposits: Employers use ACH credit to deposit wages directly into employees' bank accounts, reducing administrative overhead compared with paper checks and providing faster access to funds
• Vendor payments: Businesses frequently send invoice payments to vendors using ACH credits. It's more cost-effective than wire transfers and easier to automate for recurring invoices.
• Bill payments: Many online banking platforms allow you to push funds to utility providers, service vendors, or other recurring payees

ACH credit transactions give you more control over payment timing because you decide when the money leaves your account.

ACH debit (pull payments)

ACH debit transactions allow the recipient to pull money from your account once you authorize the payment.

Examples include:

• Subscription services: Companies like software-as-a-subscription (SaaS) platforms or utilities may withdraw payments automatically each billing cycle
• Automatic bill pay: Mortgage lenders, insurance providers, and utility companies often use ACH debit to collect payments automatically
• Membership fees: Gyms, professional organizations, and software services frequently rely on recurring ACH debit payments

ACH debit payments require prior authorization, usually through a signed agreement or online authorization form.

ACH payment fees and limits

ACH payments are widely used because they're significantly cheaper than other electronic payment methods. While exact costs vary by bank or processor, ACH fees remain relatively low.

Processing fees

Typical ACH costs include bank ACH fees and third-party fees. Bank ACH fees run about $0–$3 per transaction, while third-party processor fees are roughly 0.5%–1.5% per transaction.

Wire transfer fees are typically $15–$50 per transaction. This cost difference is one reason many businesses choose ACH transfers over wire transfers for recurring vendor payments or payroll processing.

Transaction limits

Most banks impose limits on ACH transfers to reduce fraud risk and manage transaction volume.

• Daily limits: Many banks allow daily ACH transfers between $25,000 and $100,000 depending on the account type. Business banking accounts usually have higher limits than personal accounts.
• Monthly limits: Some banks also impose cumulative monthly limits on outgoing ACH transfers. These limits help control large transaction volumes and prevent unauthorized transfers.
• Per-transaction limits: Individual ACH transfers may be capped based on account type or payment method. Same-day ACH transactions also have network limits set by NACHA.
• Business versus personal account differences: Business accounts typically support higher transaction volumes and batch processing capabilities. Personal accounts usually have stricter limits and fewer automation features.

Common ACH payment issues and solutions

Even though ACH transfers are reliable, issues can occasionally occur. These problems usually relate to incorrect information or account restrictions.

Understanding common issues helps you resolve them quickly.

Failed or rejected payments

Several factors may cause ACH transactions to fail:

• Incorrect account information: Entering the wrong routing number or account number is one of the most common ACH errors
• Insufficient funds (NSF): If your account balance doesn't cover the payment amount, the transaction may be rejected
• Closed or frozen accounts: If the recipient's account is closed or restricted, the bank will return the payment
• Retrying failed payments: Most banks allow you to retry the transaction after correcting the issue

Reversing or canceling ACH payments

ACH transactions can sometimes be reversed, but strict rules apply:

• Time windows for cancellation: You may be able to cancel a pending ACH payment before it enters the bank's processing batch
• Reversal request process: Banks typically allow reversals only in cases such as duplicate payments, incorrect amounts, or unauthorized transactions
• Dispute procedures: If you believe a payment was unauthorized, you can submit a dispute through your bank's ACH return process
• Return reason codes: Banks use standardized return codes to identify why a payment failed or was reversed

Security best practices for ACH payments

Because ACH transfers move funds directly between bank accounts, security should be a priority. Fortunately, several best practices can significantly reduce fraud risk.

Verify recipient information before sending

Always confirm routing numbers and account details before sending payments. Many businesses verify ACH payment details, such as vendor banking information, during the onboarding process to reduce the risk of payment errors or fraud.

Confirm payment instructions through a trusted channel — a direct phone call or secure vendor portal — rather than relying on email alone.

This practice helps prevent fraud schemes such as business email compromise, where attackers attempt to redirect payments by sending fake banking instructions.

Use secure networks and devices

Protect your banking credentials and payment data by using secure technology.

• Avoid public Wi-Fi networks when accessing banking portals. Public networks may expose sensitive information to interception.
• Use multi-factor authentication. MFA adds an extra layer of security by requiring a second verification step during login.

You should also ensure that devices used for financial transactions are protected with up-to-date security software. Regularly installing operating system updates and antivirus protections reduces vulnerabilities that cybercriminals may exploit.

Businesses often restrict ACH payment access to approved devices or secure company networks to further reduce risk.

Enable transaction alerts and notifications

Many banks allow you to receive real-time alerts for ACH transactions. Notifications help you detect suspicious activity quickly.

Setting up multiple types of alerts can strengthen your oversight. For example, you might receive notifications for large transfers, new payees, or failed payments. This visibility allows finance teams to quickly investigate suspicious activity and resolve issues before they escalate.

Regular account monitoring

Review your bank activity regularly to ensure all payments are legitimate. Checking your transaction history helps you confirm that vendor payments, payroll transfers, and recurring charges were processed correctly. It also allows you to identify errors such as duplicate payments or incorrect amounts.

Many businesses schedule periodic financial reviews as part of their internal controls. When paired with reconciliation software, this process can significantly improve financial oversight.

Fraud prevention measures

Businesses often implement additional controls to protect ACH payments from fraud:

• Dual approval workflows: Two authorized users must approve large ACH transfers before processing
• Vendor verification procedures: Companies confirm vendor banking information through secure communication channels
• Payment audit trails: Automated platforms track transaction history and approval steps
