How to Start Accepting ACH Payments This Week (Step-By-Step With Coastal Pay)

Let’s Define ACH and Why It Matters for Your Cash Flow

ACH stands for Automated Clearing House. It is the U.S. bank-to-bank transfer network that moves money electronically between checking and savings accounts. It is not a wire transfer. It is not a card payment. It is the same infrastructure behind direct deposit payroll, Social Security disbursements, and most vendor payment programs at mid-size and enterprise companies.

Why Business Owners Should Care Right Now

Card processing costs 2.0% to 3.0% + $0.15 to $0.30 per transaction. ACH costs a flat $0.50 to $1.50 regardless of the transaction amount. On a $5,000 invoice:

• Card at 2.9% + $0.30: $145.30
• ACH flat fee: $0.50 to $1.50

That is $143 to $145 saved on a single invoice. Over 100 such invoices per year, that is $14,300 to $14,500 recovered directly from processing costs.

Common ACH Use Cases

• B2B invoices paid via email payment link
• Monthly or quarterly professional services retainers
• SaaS and software subscriptions billed recurring
• Membership dues and association payments
• Tuition, healthcare, and institutional billing
• Franchise fee collection and multi-location billing

NACHA and Compliance

ACH payments are governed by NACHA rules covering authorization requirements, return handling, and consumer rights. Using a licensed processor like Coastal Pay simplifies compliance: the gateway handles NACHA-compliant authorization language, return notifications, and settlement reporting on your behalf.

How Do You Turn On ACH Inside the Coastal Pay Gateway Step by Step?

Step 1: Log In and Navigate to Payment Settings

Log into your Coastal Pay Gateway merchant account at coastalpay.com. Navigate to Settings or Payment Methods in the main navigation. You will see a list of available payment types, including credit cards, ACH/bank debit, and alternative payment methods.

Step 2: Submit ACH Enablement Request

Select “Enable ACH” or “Request Bank Debit.” Depending on your business profile, this may immediately activate or route to a short ACH underwriting review. The underwriting review typically completes within 1 to 3 business days. You will receive a confirmation email when ACH is active on your account.

Step 3: Verify Your Settlement Bank Account

Two verification options are typically available:

• Instant verification: Connect your bank via a secure bank-link tool. Verification completes in minutes. Your bank account is confirmed and linked for ACH settlement immediately.
• Micro-deposit verification: Coastal Pay sends two small test deposits (e.g., $0.12 and $0.35) to your account. You confirm the exact amounts in the gateway within 1 to 3 business days. Slower but widely supported by all business banks.

Micro-deposit timing is the most common source of delay for merchants wanting same-week ACH. If speed matters, check whether your bank supports instant verification before starting.

Step 4: Enable ACH as a Tender Type on Your MID

Once ACH is underwritten and your bank is verified, go to your Merchant ID (MID) settings and confirm ACH is toggled on as an accepted payment method. For multi-location merchants, confirm the tender type is enabled at each location or under the relevant MID.

Step 5: Confirm in the Dashboard

Return to your transaction dashboard and confirm that “ACH” or “Bank Debit” appears as an option in the tender type filter. Run a dummy or test transaction if a sandbox is available, or proceed to the live test in Step 4 of the 7-day checklist. Contact 888-266-1715 if the ACH option does not appear after the confirmation email.

Here’s How to Add ACH to Invoices, Checkout, and Recurring Billing

Implementation Paths by Business Model

For Invoice-Driven B2B Businesses

1. Create a Payment Link from the Coastal Pay Gateway dashboard with ACH enabled as a payment method
2. Add the payment link to your invoice template (email template or PDF) as a “Pay by Bank (ACH)” button
3. Set ACH as the default or primary option for invoices above your chosen threshold (recommended: $500+)
4. Customer clicks the link, enters routing and account number on Coastal Pay’s hosted secure payment page, and submits authorization
5. Coastal Pay’s hosted page captures and stores the NACHA-compliant authorization, including timestamp and IP for your records

For E-Commerce Sites

1. Confirm your e-commerce platform is in the Coastal Pay integration directory (WooCommerce, BigCommerce, Magento, Shift4Shop, custom cart via API)
2. Update the payment gateway plugin or API configuration to show ACH/bank debit as a checkout option
3. Configure ACH to display for cart values above a threshold where the savings justify any slight friction
4. Test in staging before going live

For Recurring Billing and Subscriptions

1. Confirm ACH recurring is enabled on your Coastal Pay MID (a specific flag in gateway settings)
2. Create a billing schedule (monthly, quarterly, annually) and connect it to your subscriber or client records
3. At customer enrollment, collect ACH authorization via Coastal Pay’s hosted enrollment link, which captures routing, account number, authorization terms, and consent timestamp
4. Test one recurring cycle with a friendly test customer before deploying to the full subscriber base

The $1 Live Test

Before going live with real customers, send yourself a $1 to $5 ACH payment from a personal or secondary bank account. Confirm the transaction appears in the Coastal Pay Gateway as “pending ACH,” the email receipt goes to the correct address, the payment descriptor reads clearly, and the amount settles to your bank account within the expected window.

What Does ACH Timing, Funding, and Risk Look Like With Coastal Pay?

Settlement Timing

• Initiated: The ACH debit instruction is submitted to the network (Day 0)
• Pending: The debit is in process, typically visible in the gateway within hours (Day 1 to Day 2)
• Settled: Funds clear and appear in your bank account, typically 2 to 5 business days from initiation
• Same-day ACH: Available at an additional fee (typically $0.05 to $0.25), settles same business day if initiated before the processing cutoff

For month-end close, initiate ACH debits 3 to 4 business days before month-end to ensure settlement timing aligns with your reporting cycle.

ACH Returns and How Coastal Pay Handles Them

A return occurs when the customer’s bank rejects the debit (NSF, closed account, revoked authorization). Coastal Pay sends an automated notification when a return occurs, showing the return reason code. Common return codes:

• R01: Insufficient funds
• R02: Bank account closed
• R10: Customer advises unauthorized (revoked authorization)
• R16: Account frozen

Set up a standard return workflow: automated email to the customer notifying them of the failed debit, a retry window of 3 to 5 business days, and a follow-up contact process for unresolved returns.

Risk Controls and Initial Limits

Coastal Pay’s risk team may set initial ACH transaction or daily debit limits for new merchants. These limits are typically reviewed and raised within 30 to 60 days of demonstrated clean processing history. Contact 888-266-1715 or submit a Helpdesk ticket to request a limit review if your typical invoice sizes exceed the initial parameters.

ACH is typically enabled within 1 to 3 business days after approval. Applying on Monday, you can usually run your first test ACH payment by Wednesday or Thursday, with first payouts landing by early the following week.

How long does it take for the first ACH payment to clear?

Standard ACH debits typically settle in 2 to 5 business days from initiation. Same-day ACH is available for an additional fee and settles the same business day if initiated before the processing cutoff. You can monitor payment status in the Coastal Pay Gateway dashboard as transactions move from “pending” to “settled.”

What documents do I need to set up ACH with Coastal Pay?

Business information (legal name, DBA, EIN, address, website), owner identity details (name, DOB, home address, SSN, ownership percentage), business checking account routing and account number (voided check or bank letter), and estimates of average ACH ticket size and monthly ACH volume.

Can I accept ACH and credit cards through the same Coastal Pay account?

Yes. Coastal Pay processes ACH, credit cards, debit cards, Apple Pay, Google Pay, PayPal, Venmo, Klarna, Afterpay, and Coinbase all through the same merchant account with unified reporting. No separate gateway subscription is required for ACH – it is bundled within the Coastal Pay Gateway.
