ACH costs 0.5% to 1.5% per transaction versus a 2.4% blended average on credit cards, settles in 1 to 3 business days versus 2 to 3 days for cards, and carries roughly one-third the chargeback risk. A peptide store routing 40% of $100,000 monthly volume to ACH saves approximately $1,400 per month and reduces its chargeback ratio measurably.
What does each payment method actually cost peptide merchants?
ACH processing runs 0.5% to 1.5% per transaction with no interchange and no card network involvement. Credit card processing runs 2.4% to 2.9% blended on a healthy peptide MID, broken down in the high-risk payment processing fees guide. On $100,000 monthly volume, the gap is $900 to $2,400 per month depending on payment mix and card types.
How do settlement times compare?
| Method | Auth | Settlement | Reserve hold |
|---|---|---|---|
| Credit card | Under 2 sec | 2 to 3 business days | 5% to 10% |
| Debit card | Under 2 sec | 1 to 2 business days | 5% to 10% |
| ACH | 5 to 30 sec | 1 to 3 business days | 0% to 5% |
ACH settles into a separate ACH account that often does not carry the same rolling reserve as your card MID, which means more working capital reaches your operating account faster.
How does chargeback risk differ?
Cards carry a 0.6% to 1.5% chargeback baseline in the peptide MCC. ACH carries a 0.2% return rate, and ACH returns are operationally different: they are not disputes but unauthorized debit or NSF flags. ACH returns do not count toward your VAMP or VDMP ratio, which protects your card MID from termination risk. Pair the ACH rail with a chargeback defense process to keep card disputes manageable.
When should a peptide store push customers toward ACH?
Three customer segments respond well to an ACH nudge: repeat subscribers, customers placing orders above $300, and customers in a checkout flow that already showed a high-fraud signal. Offering a 2% to 3% checkout discount for ACH converts 25% to 35% of these customers from card to bank transfer. The math works above $20,000 monthly volume.
What are the operational trade-offs of ACH?
ACH requires bank account verification (usually via micro-deposits or Plaid), which adds 30 to 90 seconds to first-time checkout. Returns can hit 1 to 5 business days after settlement, so reconcile ACH separately from card revenue. NSF returns are recoverable; unauthorized debit claims trigger a written rebuttal process similar to card disputes but with longer windows (60 days versus 30).
Frequently asked questions
Is ACH safe for high-ticket peptide orders?
Yes for verified bank accounts. Use Plaid or micro-deposit verification on any order above $250 to limit NSF and unauthorized-debit exposure.
Can customers chargeback an ACH payment?
Customers cannot chargeback ACH through the card networks but can file an unauthorized debit claim with their bank within 60 days. Maintain signed ACH authorizations on file to win disputes.
Should I offer ACH only or both?
Both. Card checkout maximizes conversion; ACH maximizes margin. Most peptide stores running both see 25% to 40% of revenue migrate to ACH within 6 months of launch.
