Card vs ACH vs Check: What Invoice Payments Really Cost Retail Stores
If your retail store bills commercial customers, schools, teams, or salons on account, those invoices get paid very differently from your register sales. Enter your mix below to see what card, ACH, and paper checks cost you in fees, staff time, and cash stuck in the mail.

Your payment-mix report
Four scenarios run on your numbers
| Scenario | Direct cost | Carrying cost | Total / month | Cash tied up | Days to cash | vs. current mix |
|---|
ACH-first moves 50% of your check share to ACH. Paperless moves all of it to ACH. Card for speed moves 25% to card and 50% to ACH. Card-heavy moves all of it to card. The highlighted row has the lowest estimated total monthly cost; ties go to the option with less cash tied up.

Invoice wording templates
Customers pay the way your invoice makes easiest. Put the electronic option first and the mailing address last. Replace everything in brackets.
Version 1: full invoice footer
Amount due: $[amount] by [due date] Pay online by ACH/eCheck or card in about a minute: [secure payment link] Paying by bank transfer? Use the ACH remittance details on file and include invoice #[number] in the payment reference. We will never change our bank details by email alone; call [phone] to confirm any change. Paying by check? Make it payable to [legal business name] and mail to [remit-to address]. Write invoice #[number] on the check.
Version 2: one line for the invoice email
Invoice #[number] for $[amount] is due [date]. Pay by ACH or card here: [secure payment link]. Checks are still accepted at [remit-to address].
Version 3: for customers with an AP department
Payment options (in order of preference): 1. ACH / eCheck (preferred): [secure payment link], or ACH to the account on file. Email remittance advice to [ar@yourcompany.com]. 2. Card (Visa, Mastercard, Discover, American Express): [secure payment link]. [If you apply any card fee, describe it here exactly as your card program and state rules require.] 3. Check: payable to [legal business name], mailed to [remit-to address]. Please reference invoice #[number] with every payment.
Setup checklist: ACH/eCheck and a virtual terminal
- Decide the order you will list payment options on invoices, with ACH/eCheck first if lower cost and faster cash is the goal.
- Confirm the deposit account and who at your company can see and change payment settings.
- Set up ACH/eCheck acceptance with your bank or processor. If you will pull funds from customer accounts (ACH debits), get each customer's authorization and keep a record; ask your provider which authorization format they require.
- Set up a virtual terminal for card and eCheck payments taken by phone, with a separate login for each staff member.
- Create a secure payment link or hosted payment page and add it to your invoice template and invoice emails.
- Require the invoice number in the payment reference field so payments match to invoices without manual lookups.
- Connect deposits to your accounting system and set a daily or weekly reconciliation routine.
- Write a call-back rule for any request to change bank details, using a phone number you already have on file.
- Never write down or email full card numbers. Key them directly into the virtual terminal.
- Email your customers' AP contacts with the new options and the date they start.
- Track the share of payments by method each month and rerun this comparison with the new mix.
Questions to ask any processor about pricing
- How do you quote card pricing: interchange-plus, tiered, or flat rate? Can I see a sample monthly statement?
- What fees apply beyond the rate: per-transaction, monthly, gateway, PCI, batch, or statement fees?
- What does each ACH/eCheck payment cost, and is it a flat fee, a percentage, or a percentage with a cap?
- How many business days until card and ACH funds reach my bank account?
- How are refunds, returns, and chargebacks charged?
- Which interchange categories will my business, corporate, and purchasing card payments fall into, and how does that change by card type?
- Do you support passing Level 2 and Level 3 data (tax amount, customer code, line-item detail)? From which entry points: virtual terminal, gateway, payment links, invoices?
- Is Level 2 and Level 3 data filled in automatically, or does my staff have to type it for each payment?
- Do large single payments trigger extra review, holds, or reserves, and how are those handled?
- Will my quote show interchange separately from your markup so I can see what changes on large tickets?
Passing card costs to customers
Some sellers add a surcharge to card payments, run a cash discount or dual pricing program, build card costs into prices, or offer early-pay terms for ACH. The rules for surcharges and cash discounts vary by card brand and by state, can include notice, disclosure, registration, and cap requirements, and may treat debit cards differently from credit cards. Confirm the current rules with the card brands and your state before changing how you price card payments. This report does not determine whether any practice is allowed for your business.
A lower-friction first step is to make ACH the easiest option on the invoice, using the templates above, rather than adding a fee to card payments.

Bring these numbers to the conversation. A specialist can walk through ACH, virtual terminal, and card options for your invoices. Nothing on this page is a quote.
Where invoices show up in retail stores
Most retail revenue is settled at the counter, but many stores also run a quieter invoiced side. Examples include an auto parts store with commercial accounts for repair shops and fleets, a bookstore filling school and library orders, a beauty supply store selling to salons, a pet supply store serving groomers and rescues, and an apparel shop doing team uniforms or corporate logo orders.
That side of the business usually runs on net terms, purchase orders, and paper checks that someone has to open, log, match to an invoice, and deposit. Because it is a smaller share of revenue, it rarely gets the same scrutiny as your card terminal fees, even though it can tie up more cash.
Use this tool only for the invoiced portion of your business. Enter the monthly revenue you bill on account and your average invoice, not your total store sales or your average register ticket. Mixing the two will make your check costs look smaller than they are.
Why card payments on retail invoices cost more than card payments at your register
At the register, cards are dipped or tapped, which is card-present. When a house account pays an invoice by card, the number is usually keyed into a virtual terminal or entered through a payment link. That is card-not-present, and it is often priced higher. Business customers also tend to pay with corporate or purchasing cards, which can carry higher interchange than consumer cards.
If you leave the card rate field blank, the tool uses an assumed retail effective rate of 2.55%. That assumption reflects a blend weighted toward in-store sales, so it may understate what your invoice card payments actually cost. If your statement breaks out keyed or commercial card transactions, enter that rate instead.
While you have your statement open, look for line items that hit invoiced card payments harder: non-qualified or mid-qualified surcharges on keyed and commercial cards, PCI non-compliance fees, monthly minimums, and batch or statement fees. Also ask how returns are handled. When you issue a credit memo or refund to a house account that paid by card, some pricing setups do not give back the original processing fee, so a store with frequent special-order returns pays twice.
If your average invoice is $1,000 or more, the full report adds questions to ask about large-ticket card pricing, including whether passing Level 2 and Level 3 data (such as tax amount, PO number, and line items) could lower interchange on qualifying commercial card transactions.
Worked example: a hypothetical retail auto parts store with commercial accounts
These numbers are made up for illustration, and every input below is an assumption. The store bills $40,000 a month to repair shops on account, with an average invoice of $400, or 100 invoices. 30% is paid by card (2 days to cash), 20% by ACH (3 days), and 50% by check (35 days). Other assumptions: the default 2.55% card rate, $0.50 per ACH payment, $3.00 out-of-pocket per check, staff at $25 per hour, 2 minutes per card payment, 3 per ACH, 10 per check, and an 8% annual cost of cash.
Baseline: card costs about $336 a month, ACH about $40, and checks about $514. Checks carry about $208 of staff time and about $156 in carrying cost on roughly $23,333 sitting in receivables. Total is about $891 a month (2.23% of invoiced volume), with about $24,933 tied up and a weighted 18.7 days to cash.
Scenario: moving half of the check share to ACH (card 30%, ACH 45%, check 25%) brings the total to about $684 a month. That is a saving of about $207 a month, frees about $10,667 in cash, and cuts weighted days to cash to 10.7. Moving all checks to card instead frees about $22,000 in cash, but it costs about $47 a month more than the baseline at this assumed rate. Faster is not automatically cheaper, which is why the tool shows both.

What a good result looks like for retail stores, and what the full report adds
For most retail stores, a healthy result is a shrinking check share, a total cost as a percent of invoiced volume that is not far above what you pay on counter sales, and a weighted days-to-cash figure that does not leave you short when restock or vendor invoices come due. Watch seasonal peaks. Back-to-school orders, spring team uniform orders, and holiday corporate gift orders can bring a wave of checks right when you are buying inventory, so run the tool on your busiest invoiced month as well as a typical one.
The free results show your baseline and one scenario. The full report runs four recommended mixes (ACH-first, Paperless, Card for speed, and Card-heavy) and names the lowest-cost option. It also includes an illustrative interchange-plus card estimate built on placeholder pricing assumptions; this is not a quote and not TouchSuite's actual rates. If checks make up 30% or more of your mix, the report adds an ACH/eCheck and virtual terminal setup checklist. If cash is slow to arrive, it links to our Merchant Funding Payback Estimator.

Frequently asked questions
My card rate at the register is fine. Why would card payments on house accounts cost my store more?
Invoice payments are usually keyed into a virtual terminal or paid through a link, which makes them card-not-present. Business customers also often use corporate or purchasing cards. Both can price higher than a consumer card tapped at your counter. Check your statement for a separate rate on keyed or commercial transactions and enter that in the tool instead of your overall rate.
Can I add a surcharge when commercial accounts pay their invoice by card?
Rules vary by card brand and by state, and they change. Confirm the current requirements with the card brands and your state before adding a surcharge or offering a cash or ACH discount. The tool does not assume any surcharge. It shows what each payment method costs you as-is, so you can decide whether steering customers toward ACH is worth the effort.
Our invoiced orders spike for back-to-school or holiday corporate gifts. Which month should I enter?
Run it twice: once with a typical month and once with your peak invoiced month. Peak months tend to bring more checks and longer days to cash just when you are paying for inventory, so the cash-tied-up figure is often the number that matters most during those weeks.
When I issue a credit memo or refund to a house account that paid by card, do I get the processing fee back?
It depends on your processor and pricing model, and many setups do not return the original fee. If special-order returns or credits are common in your store, ask your processor how refunds are priced. Then treat the tool's card cost as a floor, since it does not model returns.
Our repair shop and school accounts insist on paying by check. How do I move them to ACH without losing the account?
Make ACH the easiest option. Put bank payment details or a payment link on every invoice, offer eCheck through a virtual terminal for customers who want to keep their current routine, and ask your largest check payers first, since they account for most of the cost. Keep accepting checks while you switch. Use the scenario slider to see what moving even a quarter of check volume would be worth to your store.
