ACH moves money bank to bank. Used well, it cuts manual billing work, steadies cash flow, and gives patients or their families a payment option that doesn't max out a credit card. Nacha reported 35.2 billion ACH payments in 2025, nearly 5% above 2024.
This guide compares five providers: Apt Financial, Stax, PaymentCloud, Stripe, and GoCardless. It also covers how to judge pricing, recurring billing, compliance, integrations, funding speed, and fit for treatment centers.
Key Takeaways
- ACH suits recurring and high-value payments; confirm current fees and settlement terms with each provider.
- Look for recurring billing, secure authorization, return handling, reporting, and card acceptance.
- Judge underwriting, contract terms, funding speed, and support, not only the advertised fee.
- Apt Financial specializes in behavioral health and SUD treatment-center payments, including ACH, cards, and recurring billing.
Overview of ACH Payment Processing in the US Treatment-Center Industry
What ACH Processing Means
ACH is the electronic movement of funds between bank accounts over the Automated Clearing House network. An ACH debit pulls money from a payer's account. An ACH credit pushes it, as with direct deposit. "eCheck" is common industry shorthand for an ACH debit initiated online or by phone, not a separate Nacha category.
Why It Fits Treatment Centers
ACH works best where amounts are larger or recurring:
- Weekly or monthly program fees
- Deductibles and deposits
- Outstanding self-pay balances
- Sober living rent and aftercare payment plans
The Typical Workflow
- Obtain valid authorization from the payer before any debit.
- Collect and protect bank details under your security controls.
- Schedule the debit for the agreed date or billing cycle.
- Monitor settlement and returns as they post.
- Reconcile each payment to the correct patient account.
- Follow up quickly on returns and other exceptions.

Rules to Know
Under CFPB Regulation E, a preauthorized transfer from a consumer account needs a signed or similarly authenticated written authorization. Nacha also sets return-rate thresholds:
- 0.5% for unauthorized debits
- 3.0% for administrative returns
- 15.0% for overall debit returns
Nacha's 2026 fraud-monitoring rules phase in on March 20 and June 22, 2026.
Because SUD records can fall under 42 CFR Part 2, ask each processor how it handles sensitive data. This is general information, not legal advice.
The provider comparisons that follow weigh treatment-center fit, ACH and card capabilities, recurring billing, security, reporting, pricing clarity, and support.
Best ACH Payment Processing Companies for Treatment Centers in the US
This is a practical comparison, not a universal ranking. Fees, underwriting, and terms change, so confirm everything with each provider before signing.
Apt Financial
Apt Financial is a Georgia-based processor built for behavioral health and substance use disorder treatment centers. It offers ACH plus major credit and debit cards for treatment-related collections.
Key features include:
- Recurring billing and next-day settlement on card transactions
- Per-transaction pricing with no hidden fees and no long-term contracts
- Virtual terminal, pay-by-link, and in-person terminals
- Multi-location support with dashboard reporting of attempted and successful transactions
Company materials cite PCI DSS certification. Streamlined underwriting is described as approval in days, not weeks.
| Area | Summary |
|---|---|
| Treatment-center fit | SUD and behavioral health focus, hands-on support, multi-location operators, self-pay and recurring program fees |
| Payments and billing | ACH, cards, recurring billing, pay-by-link, virtual and in-person terminals, dashboard reporting |
| Commercial and security | Transaction-based pricing, no long-term contracts, PCI DSS; confirm ACH funding speed, limits, return policies, and onboarding requirements directly |
Merchants remain responsible for fees, returns, refunds, and chargebacks, so ask how each is billed.
Stax
Stax offers card and ACH acceptance, recurring patient payment plans, invoicing, text-to-pay, hosted payment pages, and a patient portal. It also describes EHR and practice-management write-backs.
Published pricing lists ACH at 1%, capped at $10 per transaction, with subscriptions starting at $99 a month. Next-business-day funding is advertised, though not specified for ACH.
| Area | Summary |
|---|---|
| ACH and cards | ACH, cards, recurring plans, invoicing, payment links |
| Treatment-center fit | Markets to healthcare; SUD eligibility and BAA availability not confirmed publicly |
| Pricing and operations | Contract length, reserves, and ACH return fees not published; ask for them in writing |
PaymentCloud
PaymentCloud serves higher-risk categories with customized underwriting, which makes it a candidate for centers that struggle to get approved elsewhere. Its ACH materials describe online, phone, and mobile acceptance, recurring billing, and account-verification tools. It states no setup fees.
| Area | Summary |
|---|---|
| Risk and underwriting | SUD underwriting is not listed in public materials; ask about reserves and documentation |
| Payment capabilities | ACH, recurring billing, cards, many gateway integrations; confirm virtual terminal and links |
| Pricing and support | ACH and card rates are quote-only; phone 800-988-2215; contract terms unpublished |
Stripe
Stripe is developer-focused infrastructure. ACH Direct Debit supports recurring payments, invoices, payment links, and APIs, with instant bank verification through Financial Connections. Published ACH pricing is 0.8%, capped at $5. Standard ACH settlement takes four business days.
It suits centers with technical staff who want payments embedded in intake or billing workflows. The catch is eligibility: Stripe's restricted-business list flags certain medical categories for review and does not name SUD treatment, so get written approval first.
| Area | Summary |
|---|---|
| ACH and recurring | Direct Debit, invoices, payment links, bank verification, APIs |
| Integration | Strong APIs; needs development resources for EMR connection |
| Risk and support | Confirm category approval, return and dispute handling, and support channels |
GoCardless
GoCardless focuses on bank debits: one-off, installment, and recurring collections through payment pages and secure links. U.S. pricing is 0.5% + $0.05, capped at $5, with a $5 failed-payment fee. Standard timing runs about four business days.
Its U.S. materials describe ACH only, so you would likely need a separate card processor. Its restricted-activities terms cover medical services unless agreed in advance, and its sales-led agreement allows reserves and automatic renewal.
| Area | Summary |
|---|---|
| Recurring ACH | Payment pages, scheduled debits, installments, authorization management |
| Suitability | Written approval for behavioral health needed; check account limits |
| Pricing and integration | Low published fees; QuickBooks, Xero, and Sage integrations; U.S. materials cover ACH only |

How We Chose the Best ACH Payment Processing
We weighed operational fit for treatment centers over brand recognition or the lowest advertised fee. Common mistakes include overlooking contract terms, return fees, reserves, integration costs, and support limits.
- Underwriting experience: Evidence the provider supports behavioral health or SUD, plus clarity on onboarding, reviews, and reserves.
- ACH functionality: Recurring and one-time debits, authorization capture, bank verification, return-code visibility, failed-payment workflows, and settlement timing.
- Payment flexibility: Cards, virtual terminals, payment links, in-person terminals, multi-location support, and EMR compatibility.
- Security and compliance: Nacha-aligned controls and PCI DSS for card data, verified certifications rather than marketing claims, and tokenization or P2PE that reduce PCI scope without eliminating it.
- Total cost and support: Transaction and monthly fees, return and chargeback fees, reserves, contract obligations, reporting, and dedicated support.

No independent ranking of ACH processors for treatment centers exists, so use your own volume and billing model to compare quotes.

Frequently Asked Questions
What is the best way to receive ACH payments?
Through a payment processor that captures payer authorization securely, initiates debits, manages returns, reconciles transactions, and deposits funds. Compare treatment-center eligibility, recurring billing, pricing, security, and support.
Is ACH payment processing safe for treatment centers?
It can be, with controls in place. Nacha rules require risk-based fraud monitoring and account validation for web debits. Confirm how your processor handles authorization, return monitoring, and sensitive health information.
How do treatment centers set up recurring ACH payments?
Choose an eligible processor, get clear written payer authorization, store a token or mandate securely, set the schedule, then monitor settlements, returns, and authorization changes.
What should treatment centers look for in an ACH payment processor?
Key factors include behavioral health underwriting, recurring billing, return handling, card acceptance, integrations, reporting, funding speed, transparent pricing, contract terms, and dedicated support.
Can treatment centers accept both ACH and credit card payments?
Many processors support both. Verify whether they share one account, reporting, and recurring billing tools, and whether pricing or compliance differ. GoCardless's U.S. materials describe ACH only.
How much does ACH payment processing cost for treatment centers?
Costs vary by provider, volume, risk profile, and contract. Published examples run from 0.5% + $0.05 to 1% per transaction, with caps of $5 to $10. Also compare monthly, return, setup, and reserve costs.
