Compare the flow, not just the payment button.
For each option, map what the customer authorizes, who receives the payment, what confirms the order and how the business receives usable funds. A familiar-looking checkout button can hide a very different sequence of steps.
Use the comparison below as a list of questions to resolve with your provider. Exact fees, timing, supported countries and return procedures belong in the written service terms.
| Method | Customer journey | Operating questions |
|---|---|---|
| Direct card processing | The customer authorizes a card payment for the store purchase. | Which merchant account and gateway are used? How are declines, disputes and settlement handled? |
| ACH debit | The customer authorizes a debit to a bank account. | How is authorization recorded, when is payment confirmed, and what happens if it is returned? |
| Crypto payment | The customer sends a supported asset on a supported network. | Who handles confirmation, incorrect amounts, network fees, conversion and refunds? |
| Card-funded crypto flow | The shopper pays by card. The partner settles the merchant in USDC or another agreed asset. | Which card brands, what does the statement say, and when do you receive USDC or fiat? |
ACH has its own authorization and return requirements.
Nacha’s guidance distinguishes ACH credits from debits and explains authorization requirements for collecting payments. Stripe’s ACH documentation also describes delayed confirmation and possible failures or disputes. Do not treat a bank debit as an instantly final payment simply because a customer submitted bank details.
Ask the provider how your store should respond to a pending payment, a return after an initial success notification and a refund request. Agree on a fulfillment rule that your staff can follow. Do not collect customer banking credentials through an ordinary contact form.
Crypto and card-to-crypto are different checkout choices.
A crypto payment and direct card processing are different arrangements. The FTC explains that cryptocurrency payments generally lack the same dispute protections as card payments and are typically difficult to reverse. Your refund process and customer instructions should reflect the actual method.
An onramp is a service for purchasing crypto using supported funding methods. Coinbase’s documentation illustrates that card and bank availability can vary by country and funding source. Its inclusion here explains the mechanism; it does not establish provider acceptance for your business.
If an offer is described as “credit cards for peptides” or “cards with crypto settlement,” request a written diagram of the full flow. Confirm the merchant of record, buyer verification steps, statement descriptor, fees and refund responsibilities. Never present an unrelated purchase or concealed payment route as direct processing for your catalog.
Card-funded crypto settlement is its own option.
If you want customers to pay by card and you want to be paid in USDC, say that directly. In the usual version of this flow, the shopper does not need a wallet. A partner widget takes the card payment and settles you in crypto, or in fiat, on its schedule. Checkout can be built to feel like a standard card payment. That does not make it a traditional merchant account.
Treat partner marketing carefully. Cardholder verification, limits, and countries depend on that partner. Many card-to-crypto partners advertise low-friction checkout. Confirm KYC and the written fee and timing terms before you describe the button to customers. Alderwell can introduce you. The partner underwrites and processes.
- Shopper pays by card through the partner’s checkout.
- You receive USDC, USDT, or fiat, as the agreement states.
- Chargebacks, reserves, and settlement timing are questions for that partner, not assumed network rules.
Add cards around the business you actually operate.
Prepare your exact products, business country, fulfillment model, current sales records and target card volume. Be clear whether you want to retain ACH or crypto, replace one of them, or give customers a choice. List required subscriptions, saved payment methods, currencies and checkout integrations.
Alderwell can help prepare these requirements for a processing-partner introduction. The partner determines eligibility and terms. Changing the payment method does not change your product obligations or resolve funds held by an earlier provider.
Your preparation checklist
- Write down the current customer journey for each method.
- Request the full payment flow and contracting-party names for any new offer.
- Ask how pending, failed, returned and refunded payments update store orders.
- Confirm exactly what buyers see on statements and checkout screens.
- Evaluate customer completion and support needs alongside total costs.
Common questions
Can a research peptide store add credit cards if it already accepts ACH?
It can request a product-specific card-processing review. Existing ACH acceptance does not establish card eligibility. The actual substances, intended use, customers, claims, locations and provider policies matter.
Are ACH payments free from returns or disputes?
No. ACH debits have authorization and return requirements. Ask your provider for the procedures and timelines that apply to your account and how to handle fulfillment while a payment is pending.
Is a card-to-crypto checkout a merchant account?
Do not assume so. Determine what the customer buys with their card and which entity accepts that payment. A crypto purchase used to fund a later transaction is different from direct card processing for the store purchase.
Which method has the lowest cost?
There is no single answer without the actual offers and your transaction mix. Compare transaction charges, monthly fees, conversion costs, refunds, returns, support work and any reserve requirements. Evaluate held reserves separately from processing fees.
