Real-Time Payment Processing: How RTP Payments Work and How to Accept Them

Real-time payment processing moves money from one bank account to another in seconds, with funds cleared, settled, and available to the recipient immediately — 24 hours a day, 365 days a year. In the United States, most real-time payments travel over the RTP network operated by The Clearing House, which moves the payment and its messaging data together so both sides receive instant confirmation.

That combination of speed, finality, and data changes what businesses and consumers can expect from a transaction. This guide explains what RTP means in banking, how RTP payments work, why an "RTP credit" might appear on your bank statement, how real-time payments compare with ACH and wire transfers, and how merchants can accept real-time payments through a real-time payment processor.

What Is Real-Time Payment Processing?

Real-time payment processing is the clearing and settlement of an electronic payment within seconds of initiation. Instead of collecting transactions and settling them in scheduled batches, a real-time system processes each payment individually, the moment it is sent. Money and messaging move together: the payment instruction, remittance details, and confirmation messages travel as one package, so the sender knows the payment was delivered and the recipient knows the funds are available.

Real-time payments — also called instant payments — are now an established part of US banking rather than an emerging experiment. The Clearing House (TCH), owned by some of the world's largest banks, launched the RTP network in 2017 in partnership with Mastercard and Vocalink, and the Federal Reserve added a second instant payments rail, the FedNow Service, in 2023. Meanwhile, the continued growth of ecommerce payment processing and mobile commerce keeps raising expectations: according to the Federal Reserve, most companies and consumers would prefer transactions that clear instantly or within an hour.

What Does RTP Mean in Banking?

In banking, RTP stands for Real-Time Payments, and it usually refers specifically to The Clearing House's RTP network. If your bank statement or banking app shows an RTP entry, money moved over that network. Four characteristics define RTP payments:

• Credit-push only. The sender initiates every RTP payment by pushing funds from their own account. Nothing can be debited, or pulled, from an account over the RTP network.
• 24/7/365 availability. RTP payments clear and settle around the clock — nights, weekends, and holidays included — with no banking-day cutoffs.
• Settlement in seconds. Funds are typically available to the recipient within seconds of the sender authorizing the payment.
• Irrevocable. Once sent, an RTP payment is final. That finality gives recipients certainty, and it means senders should confirm payment details before authorizing.

One nuance worth knowing: "real-time payments" in lowercase can describe the broader category of instant payment systems, while RTP in a US banking context almost always means TCH's network. Banks and credit unions must be network participants — and specifically enabled to receive RTP payments — before their customers can use it, and some institutions participate as receive-only.

How RTP Payments Work: The Request for Payment (RFP) Flow

Because RTP is credit-push only, a business cannot pull funds from a customer's account the way an ACH debit does. Instead, the network relies on a messaging feature called Request for Payment (RFP) — often described as "request to pay" — which lets a biller ask for payment while the payer stays in control. A typical RTP transaction between a biller and a consumer follows four steps:

• The biller sends a Request for Payment. The RFP works like an electronic invoice delivered through the consumer's own bank, carrying the amount due, the due date, and remittance details.
• The consumer submits payment. The consumer reviews the request in their banking app or portal and authorizes an RTP credit transfer from their account.
• The biller confirms receipt. Funds settle in seconds, and the biller's bank returns an immediate confirmation that the money arrived.
• The transaction is finalized on the consumer's end. The consumer receives a payment receipt and status message, and the payment is complete and irrevocable.

The entire exchange — request, payment, settlement, confirmation — happens in seconds. Just as valuable is the data that rides along with it: RFPs support electronic invoices and billing, credit transfers carry remittance information, and senders receive payment receipts and status messages. Payments arrive already matched to the invoices they pay, which simplifies reconciliation for businesses.

What Is an RTP Credit (and Why Did You Receive One)?

An RTP credit is an incoming real-time payment: money that someone pushed to your bank account over the RTP network. On a statement, it may appear as "RTP credit," "real-time payment credit," or "RTP received," usually alongside the sender's name. Because the network is credit-push only, an RTP credit always means funds came in — never that money left your account.

Common reasons you might receive a real-time payment credit:

• Payroll and earned wage access. Employers and earned-wage apps use RTP to deliver pay instantly, including same-day and off-cycle payouts.
• Gig and marketplace payouts. Rideshare, delivery, and marketplace platforms push driver and seller earnings out in real time, any day of the week.
• Insurance disbursements. Insurers use RTP to get claim money to policyholders when speed matters most.
• Refunds. Merchants can return money to customers in seconds instead of days.
• Account-to-account transfers. Moving money between your own bank accounts, or receiving funds from another person.

If you don't recognize an RTP credit, start with the sender details on the statement line, and contact your bank if the payment still looks unfamiliar. The funds are final and immediately available, but your bank can help trace where they came from.

RTP vs. ACH, Same Day ACH, and Wire Transfers

The clearest way to understand real-time payments is to compare them with the payment rails businesses already use.

Real Time Payment Processing vs. Batch Processing

The Automated Clearing House (ACH) network — one of the largest payment systems in the world — relies on batch processing: transactions accumulate throughout the day and process together in scheduled batches, so settlement is not immediate. Same Day ACH shortens the wait with same-business-day processing windows, but it is still batch-based and still tied to banking days. Real time payment processing removes the batch entirely: every transaction clears and settles individually, the moment it is initiated.

Here is how the four rails compare on speed, hours, finality, and typical cost:

• RTP: Settles in seconds, 24/7/365. Credit-push only, and every payment is final once sent. Typically priced as a small flat fee per transaction.
• Standard ACH: Batch-processed, generally settling within one to three business days, on banking days only. Supports both credits and debits, and transactions can be returned or reversed in limited circumstances. Usually among the lowest-cost ways to move money — see our ACH payment processing page for how merchants use it.
• Same Day ACH: Batch-processed with same-business-day settlement windows. Much faster than standard ACH, but still bound by banking days and cutoff times.
• Wire transfer: Processed individually and typically settled the same day, but only during bank business hours. Irrevocable like RTP, and usually the most expensive option per transfer.

In practice, the rails complement one another. ACH remains the workhorse for low-cost, high-volume payments and recurring debits, wires handle large one-time transfers, and an RTP transaction fills the gap whenever money needs to arrive — and be final — in seconds, at any hour.

RTP Use Cases and Examples

Real-world RTP examples cluster around moments when waiting days for settlement creates friction, risk, or a poor customer experience. The most common RTP use cases include:

• Instant payroll and earned wage access — paying employees and contractors the same day they work, without waiting for a batch payroll run.
• Gig economy and marketplace payouts — sending driver, courier, and seller earnings the moment they are earned, weekends included.
• Insurance claim disbursements — delivering claim payments in seconds during emergencies.
• B2B invoice payments via Request for Payment — a supplier sends an RFP, the buyer pays it instantly, and remittance data arrives attached to the payment.
• Instant refunds — returning funds to customers immediately, which can improve the post-purchase experience and reduce support tickets.
• Account-to-account (A2A) transfers — moving money between a customer's own accounts, or from person to person, with immediate availability.

If several of these look like your business, RTP money transfers are worth a serious look alongside your existing card and ACH volume.

RTP Vendors and Network Participants

"RTP vendors" is a broad label covering several distinct roles in the ecosystem. Here is who does what:

• The Clearing House (TCH). The network operator. TCH built and runs the RTP network, developed in partnership with Mastercard and Vocalink.
• Participating banks and credit unions. Financial institutions connect to the network directly or through third-party service providers. An institution must be enabled to receive RTP payments before its customers can get them, and some participate as receive-only. If a real-time payment fails, the recipient's bank may simply not be an RTP participant yet.
• Payment processors and merchant services providers. These companies connect businesses to the network through their banking partners and handle onboarding, underwriting, settlement, and reporting.
• Payment gateways. The software layer that links a business's website, invoicing, or billing system to the processor and the bank rails behind it.

Where a Real-Time Payment Gateway Fits

A real-time payment gateway plays the same role for RTP that a card gateway plays for credit cards: it passes transaction data securely between your software and the payment network. For RTP, that means presenting Requests for Payment, listening for instant status messages, and confirming settlement in real time. Most businesses do not buy a real time payment gateway as a standalone product — it comes integrated through their payment processor or merchant services provider, which is why choosing the right provider matters.

How to Accept Real-Time Payments: Choosing a Real-Time Payment Processor

Merchants cannot connect to The Clearing House directly. Access runs through participating financial institutions and the processors built on top of them — so accepting real-time payments, in practice, means working with a payment processor or merchant services provider that offers RTP capability alongside your existing payment methods.

What Does a Real Time Payment Processor Do?

A real time payment processor supplies the connection between your business and the RTP network. That typically includes setting up your merchant account, providing the gateway or API you use to send Requests for Payment and receive credits, routing transactions through a participating bank, and delivering reporting that lets you reconcile instant payments alongside your card and ACH volume.

Real-Time Payments Through Merchant Services

For most businesses, real-time payment capability comes from merchant services — the same provider relationship that already powers card and ACH acceptance. Not every provider supports RTP yet, so when you evaluate real-time merchant services, ask up front: Do the provider's banking partners participate in the RTP network? Does its gateway support Request for Payment messaging? How would instant payments plug into your current checkout, invoicing, or payout flows?

How to Evaluate a Real-Time Payment Processor

When comparing providers, work through this checklist:

• Network access and certification. Confirm that the processor's partner banks participate in the RTP network and are certified to receive RTP payments — without that connection, "instant" is not possible.
• Gateway integration. Look for RTP and RFP support that integrates cleanly with your website, billing platform, or software stack.
• Payout speed. Understand exactly how quickly funds reach your account, and whether that speed holds on nights, weekends, and holidays.
• High-risk underwriting. If you operate in a hard-to-place industry, choose a provider experienced with high-risk merchant accounts so underwriting does not stall your setup.
• Pricing. Compare per-transaction fees, monthly costs, and any gateway or integration charges against your ticket size and volume.
