Why ACH, When It Makes Sense

Card processing isn't always the right tool. For recurring invoices, larger B2B payments, or customers who prefer paying by check, ACH payment processing moves the money bank-to-bank instead of through a card network — no trip to the branch to deposit a paper check, and no interchange fee calculated as a percentage of a transaction that might run into five figures. On a $500 sale, that difference is a rounding error. On a $15,000 invoice, it's real money that stays in your account instead of a processor's.

For businesses billing five- and six-figure invoices on a recurring basis, ACH isn't a fallback payment option — it's often the one that protects your margin the most.

Common Challenges

Common ACH Payment Challenges

The same five issues come up again and again for businesses relying on paper checks or card-only processing.

Manual Check Deposits Eating Staff Time

Trips to the bank, deposit slips, and delayed visibility into what's actually been paid.

Card Fees Eroding Margin on Large Invoices

Interchange on a $10,000 invoice costs far more in dollar terms than the equivalent ACH transfer.

Failed or Returned Payments

Insufficient funds or invalid account numbers, with no automated retry process to catch it.

Slow Reconciliation

Matching incoming payments to open invoices by hand instead of automatically.

Recurring Billing That Requires Manual Re-Entry

Re-running the same charge every cycle instead of an automated, set-it-and-forget-it schedule.

Questions

ACH Payments FAQ

Pricing & Fees

How much does ACH processing cost compared to credit cards?

ACH is typically priced as a flat or capped fee per transaction rather than a percentage of the sale, since it doesn't carry card network interchange. On larger transactions, this usually costs meaningfully less than the equivalent card payment — the savings scale with the transaction size, so the difference is most noticeable on invoices in the thousands of dollars.

Is there a limit on how large an ACH transaction can be?

ACH doesn't carry the same practical ceiling that some card transactions face, which is part of why it's commonly used for large B2B invoices and contract payments. Specific limits can still apply depending on your account and risk profile — ask your account contact if you're processing unusually large transactions.

Are there fees for failed or returned ACH payments?

Yes, a return fee typically applies when a transaction fails due to insufficient funds or invalid account details, similar in concept to a bounced check fee. We disclose this upfront and help you set up automated retry logic to reduce how often it happens.

Do I need a separate account to accept both ACH and cards?

No. Your ACH and card processing run through the same Argent account and report into one dashboard, so you're not reconciling two separate statements for one business.

Is same-day ACH available?

Same-day ACH is available for an added fee in many cases, settling faster than the standard one-to-three-business-day timeline. Ask your account contact whether it's a good fit for your specific billing schedule.

Setup & Compatibility

How do I set up recurring ACH billing?

Your customer authorizes the debit once, typically through a signed form or online consent, and the schedule runs automatically from there — no manual re-entry required each cycle. We help configure the schedule and retry logic during setup.

Can I accept ACH payments through an online invoice?

Yes — ACH pairs directly with our electronic invoicing solution, so customers can pay a bank transfer directly from an emailed invoice link instead of mailing a check.

How long does it take to start accepting ACH payments?

Most standard accounts are approved and set up within a few business days, similar to card processing. Higher-volume or specialized accounts may take slightly longer during underwriting review.

Do I need special equipment to accept ACH payments?

No hardware is required — ACH payments are authorized and processed through a secure online form, invoice link, or virtual terminal rather than a physical card reader.

Can I store a customer's bank details for future payments?

Yes, through our Customer Vault solution, bank account details are tokenized and stored securely for repeat customers, the same way we handle card-on-file storage.

Support & Security

How secure is ACH compared to a paper check?

ACH transfers are encrypted and processed through a regulated banking network, which generally offers stronger security and tracking than a paper check that can be lost, altered, or delayed in the mail.

What happens if a customer's ACH payment is returned?

You'll get an automated notification with the specific return code — insufficient funds, invalid account, or similar — and we help you configure a retry schedule so a temporary issue doesn't require manual follow-up every time.

Can a customer dispute an ACH payment the way they'd dispute a card charge?

Customers can dispute an unauthorized ACH debit through their bank, though the process and timelines differ from a card network chargeback. Keeping clear authorization records (signed forms, timestamped online consent) is your best protection if a dispute comes up.

Who do I contact if an ACH payment doesn't show up as expected?

You'll have a named point of contact on your account team, not a general support queue, who can look into a specific transaction directly.

Can I switch from manual check deposits to ACH without disrupting my customers?

Yes — most businesses phase it in by offering ACH as an option alongside checks and cards, then gradually shifting recurring customers onto it rather than a hard cutover.
