You’re paying 2.8% per transaction on credit card volume. That’s $2,800 on $100,000 in monthly sales. Your processor mentions ACH processing: “Low costs. Fewer chargebacks. Might work for your model.”
Here’s the truth: most high-risk merchants are leaving money on the table by not offering ACH. It’s cheaper, has fewer chargebacks, and for the right customer base, can massively improve your margins. But it’s not right for every business. Here’s when it makes sense.
What Is ACH and How Does It Work
ACH stands for Automated Clearing House. It’s a system for moving money between bank accounts electronically. When a customer pays via ACH, they’re giving you authorization to withdraw money directly from their bank account—no credit card required.
How ACH works: Customer provides bank account info (account number, routing number) → You submit an ACH transfer request → The ACH network processes the transfer (1–3 business days) → Money lands in your bank account.
| Factor | Credit Card | ACH |
|---|---|---|
| Processing cost | 2.5–3.5% | 0.5–1.5% |
| Settlement time | 1–3 days | 1–3 days |
| Chargebacks | Common (1–2%) | Rare (0.1%) |
| Customer ease | Click and pay | Enter bank info |
| International | Yes | Limited (mostly US) |
| Customer friction | Very low | Medium |
The ACH Cost Advantage
Credit card processing on $100,000/month costs roughly: $2,800 in transaction fees + $500 in chargeback fees + $7,000 in held reserves. Total: $10,300.
ACH processing on $100,000/month costs roughly: $800 in transaction fees + $50 in ACH returns + $2,000 in held reserves. Total: $2,850.
The difference: $7,450 per month. $89,400 per year. On a $100K/month business, switching 50% of volume to ACH could save you $45,000 a year in processing costs.
When ACH Makes Sense for Your Business
B2B Transactions
Businesses paying other businesses almost always prefer ACH—it’s how enterprise payments work. If you’re selling B2B services or high-ticket products to businesses, ACH should be a primary payment method. A $5,000/month consulting client would much rather pay via ACH than process it as a credit card.
Subscription Payments
Subscription businesses get destroyed by chargebacks. ACH returns are much rarer. A customer who authorizes a recurring ACH payment is far less likely to dispute it than a customer who sees a credit card charge. If you have a subscription model, offering ACH could cut your chargebacks in half.
High-Risk Customers with High Chargeback Rates
If your customer base has high chargeback rates—adult, gaming, international—ACH can be a pressure relief valve. Offer it as an alternative. Those customers have dramatically lower ACH return rates. Even if 15% of players on an iGaming platform use ACH instead of credit cards, your overall chargeback ratio drops meaningfully.
Price-Sensitive Customers
Some customers specifically choose ACH to avoid credit card fees. If you can offer an ACH discount—“Pay by bank transfer and save $15”—some customers will take it. You save on processing and they get a better price.
When ACH Doesn’t Work
ACH is great in specific scenarios, but don’t force it everywhere. It doesn’t work well for one-time consumer purchases (too much friction for a $50 buy), international customers (US bank accounts only), impulse purchases (credit cards win on speed), or customers who don’t know you yet (asking for bank access is a higher-trust ask than a card number).
How to Implement ACH: The Operational Guide
Get Customer Authorization Properly
This is critical. You must get explicit written authorization before debiting a bank account. Present an authorization agreement, get a digital signature, keep it on file, and email them a copy. If you don’t have proper authorization and a customer disputes it, you lose automatically.
Communicate the Timeline Clearly
ACH takes 1–3 days to settle. Credit cards are instant. Tell your customer upfront: “ACH payments take 2–3 business days to process. We’ll notify you when the payment has been received.”
Provide Easy Updates and Cancellation
Customers need to be able to update ACH info or cancel easily. If cancellation is hard, they’ll dispute the payment instead. Make sure your system allows one-click cancellation, easy ACH info updates, and straightforward reactivation.
Set Up Return Handling
ACH transfers can be returned (equivalent to chargebacks) for disputes, insufficient funds, or closed accounts. Notify the customer immediately, retry after a few days for NSF returns, and offer alternative payment methods.
ACH for High-Risk Merchants: A Competitive Advantage
Banks are extremely strict about ACH for high-risk merchants. Most processors won’t support it because their banking partners won’t allow it. But processors that specialize in high-risk—like Karma Card Payments—have banking relationships that support ACH for high-risk merchants. This gives you an alternative payment method that reduces customer frustration, dramatically lowers chargeback rates, and cuts your processing costs.
