Real-Time Payments Explained: RTP and FedNow for U.S. Businesses

Years ago, businesses might wait weeks for a check to be mailed and received from a customer. Even after you dropped the check off at the bank, it could be days until it cleared your account.

Today, real-time payments (RTP) have made multi-day waits a thing of the past. These instantaneous payments can transfer into the recipient’s account immediately. From avoiding late payments to paying vendors, there are many real-world uses of RTP payments and FedNow payments.

To give you a better understanding of how these work, we’ll delve into the costs, availability, and other factors involved in using RTP and FedNow payments at your company.

TL;DR

• With real-time payments, you can transfer funds in seconds and get an immediate confirmation.
• Both RTP and FedNow offer real-time payment processing and bank-to-bank account transfers.
• ACH uses a batch-based system. These batches are settled on the same day or within the next one to two days.
• Wire transfers can occur on the same day, but they are only available during banking hours. They typically have higher fees, which is why they are often reserved for high-value purchases.
• RTP and FedNow are both effective options for time-sensitive payments, so the major question is whether the rail is an available option for the transaction. 
• RTP is an effective option for bill pay, instant payouts, payroll, P2P payments, loan disbursements, and other payments where time is of the essence.
• Because RTP is irrevocable, it’s essential to update your payment workflow with adequate security measures.

RTP and FedNow can be incorporated into your existing payment options. They are best used when instantaneous payments are needed and are not intended to be the only payment option your company uses.

What Are Real-Time Payments? 

As the name suggests, real-time payments are payments that are processed in real time. They occur almost instantaneously, making them ideal for any transaction where time is of the essence. Because they don’t rely on waiting periods or batching, they can take place at any time of the day or week.

The Benefits of Using RTP

These payments are sent using the Clearing House’s RTP network. It offers a few essential benefits.

• Instantaneous settlement
• 100% uptime
• Smart messaging for real-time reconciliation
• Broad reach, including 125 million transactions in just the last quarter of 2025
• $10 million transaction limits

Whether you are looking for liquidity or want faster invoicing at your small business, RTP payments can help. They are often used for insurance disbursements, bill pay, automated receivables, person-to-person (P2P) transfers, streamlined disbursements, cash concentration payments, merchant settlement, and gig economy disbursements.

How Is RTP Different From FedNow?

There are a few distinct differences between the real-time payment network and the FedNow payment system. Launched in 2023, FedNow was designed to be a real-time interbank clearance and settlement service.

FedNow uses the Federal Reserve infrastructure to reach depository institutions. Like RTP, it currently has a transaction limit of $10 million and handles a high volume of payments. Both programs are bank-to-bank account rails, offer excellent transaction security, and provide instantaneous transfers. 

What’s the Difference Between RTP and ACH?

Automated Clearing House (ACH) is a type of electronic funds transfer (EFT) that uses a batch approach. About half of the commercial ACH volume in the United States is handled by the Clearing House. The remainder goes through the Federal Reserve’s FedACH.

When comparing RTP vs. ACH, one thing that stands out is the time difference. While real-time payments occur in seconds, ACH is processed on the same day or within one to two business days. Additionally, ACH is only available during business days. While ACH offers broad coverage, RTP is better if you want instant confirmation and delivery.

RTP vs. ACH vs. Wire: How the Main Bank Rails Compare

Besides comparing RTP vs. ACH, it also helps to review other bank rails. Wire transfers are significantly different from RTP payments and the FedNow payment system. To get a better understanding of how RTP, ACH, and wire transfers compare, read on.

	RTP	ACH (Same-day and standard ACH)	Wire Transfers
Speed	Confirmation arrives in seconds.	It can be transferred on the same business day or in one to two days.	Transfers occur on the same day. In most cases, it takes just a few minutes.
Availability	It is available 24/7/365.	ACH is available on business days only.	It is typically available on business days based on the hours the bank is open.
Settlement Timing	Settlement happens immediately.	Settlement occurs a maximum of four times a day during banking days only.	Settlement is immediate.
Reversibility	RTPs aren’t reversible.	ACH may be reversible under certain conditions.	Wire transfers are not reversible.
Best Uses	It works for bill payments, B2B payments, and any supplier payment where timing is crucial.	This option is effective for recurring invoices, payroll, and non-urgent payments. In exchange for a slower speed, ACH offers a low-cost way to send money.	This payment method is effective for high-value, time-sensitive payments, such as real estate closings.
Money Limits	The limit is $10 million per transaction.	Users face a limit of $1 million per transaction for same-day ACH services.	The limit varies, depending on the bank involved.

How Do RTP Payments Differ From the ACH Network and Wire Transfers?

RTP payments differ from traditional rails in a few key ways. You’ll generally want to use RTP as a part of your comprehensive payment strategy and not a sole solution.

• Speed: Unlike ACH and wire transfers, RTP is processed in seconds. Even with same-day ACH, the transfer can take hours to complete.
• Availability: RTP is available 24/7/365. In comparison, ACH is available only on business days. Wire transfers are limited to business hours and business days.
• Settlement: The real-time payment network is known for its immediate, irreversible payments. While wire transfers are also irreversible, ACH payments can be reversed.

Cost: Real-time payments and ACH generally cost less than wire transfers.

When Do Real-Time Payments Make Sense? 

Whether you are a small business, major corporation, or consumer, there are a few different types of situations where you might send and receive RTP payments.

• Instant Payouts: Any situation that requires fast, confirmed payments is ideal for the real-time payment network.
• Time-Sensitive B2B Transactions: If your business has to transfer money to a vendor or a strategic partner as quickly as possible, RTP is a good route.
• Insurance Claims: Policyholders are often desperately in need of insurance payouts to repair or replace their vehicles. RTP ensures that these payments arrive as quickly as possible.
• Bill Payments: If you are pressed for time and concerned about late fees, RTP can help you instantly pay your utilities and other bills.
• Loan Disbursements: When someone qualifies for a loan, RTP can be used to immediately send the loan disbursement to the borrower.
• Payroll: RTP is excellent for payroll disbursements because it allows workers to immediately receive their wages.
• P2P Transfers: Whether people are splitting a bill or need to share a utility bill, P2P transfers allow them to send money quickly.
• Ecommerce Refunds: RTP enables people to immediately get their money back after they return an ecommerce purchase.

Key Limitations and Costs Associated With RTP

While there are benefits to using real-time payments, there are also key drawbacks to consider as well. 

Not Universal

First, it is not used universally yet. While 71% of United States demand deposit accounts can use this option, it is not used by everyone.

Not a Pull Payment

It’s also worth noting that this is a credit push and not a credit pull payment. With push payments, the payer initiates the payment. Pull payments, such as many utility bills and recurring payments, are initiated by the recipient. 

Not Revocable

Once you decide to send an RTP payment, it is irrevocable. Unless the recipient decides to return the money, you don’t have a way to get the funds back.

Not Free

Although RTP is cheaper than wire transfers, it is not without fees. The network fee is only one piece of the puzzle. Businesses typically have to pay bank or provider markups as well. You may also have to spend money on implementation costs, such as updates to your reconciliation workflows, improved fraud control, and approval workflows.

How RTP and FedNow Fit Into Your Existing Payment Workflow

While there are many advantages to using the FedNow payment system and RTP payments, these aren’t the only payment options out there. They can be used as instant rails alongside your existing ACH and wire transfer options.

In practice, you can use FedNow and RTP for time-sensitive supplier payments, invoices, and vendor payouts. They can be used to pay a contractor, send out a refund, or instantly send an insurance payout. Your accounts receivable department can take advantage of these methods when immediate, confirmed payments are needed, such as for past-due accounts and restoring services. 

Because the payments are irrevocable and can occur at any time, it’s essential to update some of your security policies. You’ll need to change your approval tiers, velocity handling, recipient eligibility checks, and payee verification.
