Card vs ACH vs Check: Payment Cost Comparison for Subscription Businesses
Subscription businesses bill the same customers again and again, so a small cost difference per invoice repeats every renewal. Enter your billing mix to see what card, ACH, and paper checks cost you each month in fees, staff time, and cash waiting to arrive.

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.

How subscription businesses should fill in the calculator
Business type: no option says "subscription," so pick the one closest to how you sell. Software, memberships, and boxes sold online usually fit eCommerce. Managed services, retainers, and maintenance contracts fit Professional services. Recurring supply orders to other companies fit B2B. The business type only sets the default card rate, so the more useful step is entering your own effective rate. Divide last month's total processing fees by last month's card volume.
Average invoice: if you sell both monthly and annual plans, the blended average hides the difference. A $99 monthly invoice and a $1,188 annual prepay have very different card economics. Run the calculator once for each plan type, using each plan's own volume.
Days to cash: for cards on file charged automatically on the renewal date, days to cash is roughly your settlement time, usually a day or two. Count from the invoice date, not the charge date. If you send an invoice and wait for the customer to click and pay, use that real gap instead.
Staff minutes: subscription businesses rarely spend time on card payments that succeed. They spend it on the ones that fail. Raise your per-card minutes to cover retries, dunning emails, and calls to update expired cards. Do the same for ACH if you handle returned debits.
Where payment costs hide in subscription billing
Recurring card charges are card-not-present, which generally carries higher interchange than tapping a card in person. The processor's markup and fees sit on top of that. When you review your statement, look for line items that add up quietly on a recurring model: - Per-transaction gateway fees - Recurring-billing or subscription module fees - Card account updater fees - PCI compliance or non-compliance fees - Chargeback fees - Monthly minimums None of these is wrong by default. You should still know what each one costs you per renewal.
ACH autopay is often the cheapest way to collect recurring revenue, but it is not free of work. You need the customer's authorization for recurring debits. Returns for insufficient funds or closed accounts can arrive days after the debit. Confirm authorization and return-handling requirements with your bank or processor.
Paper checks tend to come from larger business customers whose accounts payable team runs on net-30 or net-45 terms. They can be your best accounts and your slowest cash at the same time.
Seasonality matters too. Annual plans often renew in clusters, such as January, the end of a customer's fiscal year, or the anniversary of a big launch. A cluster of large check-paid renewals can tie up a large amount of cash for weeks.
Worked example: a hypothetical subscription business
These numbers are entirely hypothetical. Assume $60,000 a month in invoices at a $500 average, which is 120 invoices. The mix is 50% card, 30% ACH, and 20% check. Days to cash are 2 for card, 3 for ACH, and 35 for check. Other assumptions: a 3.0% card effective rate entered by the user, $0.50 per ACH payment, $3.00 out-of-pocket per check, staff at $35 an hour, and 2, 3, and 10 staff minutes per card, ACH, and check payment. The cost of cash is 10% a year.
Baseline results: - Card: $970 a month in direct cost, about $16.17 per invoice - ACH: $81 a month, $2.25 per invoice - Check: $212 a month, about $8.83 per invoice, plus $14,000 in cash tied up - Total: about $1,411 a month, with $17,800 tied up and a weighted 8.9 days to cash
Moving all check volume to ACH lowers the total to about $1,147 a month, a saving of roughly $265 a month. It frees $12,800 in cash and cuts weighted days to cash to 2.5. Moving all check volume to card instead frees slightly more cash, $13,200, but costs about $66 a month more than the baseline. At a $500 ticket, the card fee outweighs the cost of waiting for the check.

What a good result looks like for subscription businesses
A healthy subscription mix usually keeps routine renewals on automatic methods, either card on file or ACH autopay. Checks are reserved for the few accounts that insist on them. In your results, look for three things: - A low weighted days to cash - Little cash tied up relative to one month of revenue - A card cost per invoice you can justify by fewer failed payments or faster collection
The free results show your baseline and one scenario. The full report runs four recommended mix scenarios, from moving half your check share to ACH to moving all of it to card, and names the lowest-cost option.
The report also includes an illustrative interchange-plus card estimate based on placeholder pricing assumptions. It is not a quote and not TouchSuite's actual rates. If your average invoice is $1,000 or more, which is common for annual prepays, the report adds questions to ask about large-ticket card pricing and Level 2/Level 3 data. If checks are 30% or more of your volume, it adds an ACH, eCheck, and virtual terminal setup checklist.

Frequently asked questions
Should I steer annual-plan customers to ACH instead of card?
Often it is worth testing. On a large annual invoice, a percentage-based card fee becomes a big dollar amount, while an ACH fee is usually a flat per-payment cost. Enter your annual-plan volume and average invoice on their own and compare. Also weigh the tradeoff: some customers prefer card for the points or the payment timing, and making checkout harder at renewal can cost you the renewal.
Our billing system charges cards automatically on the renewal date. Does the days-to-cash input still matter for us?
Yes, but the number will be small. Use your settlement time, plus any gap between when you issue the invoice and when the charge runs. Where days to cash really matters for subscription businesses is check-paying accounts on net terms. If your check days reach 45 or more, the full report links to the Merchant Funding Payback Estimator at https://touchsuite.com/tools/merchant-funding-payback-estimator.
How do I account for failed card payments and involuntary churn?
The calculator does not model lost customers directly. Capture the cost of failed payments in the staff-minutes inputs. If your team spends time on retries, dunning emails, and card updates, spread that time across all card payments and raise your minutes per card accordingly. Revenue lost when a customer churns because their payment failed is a separate figure to track in your billing reports.
Can we add a fee for subscribers who pay by card, or offer a discount for ACH?
Rules on surcharges, convenience fees, and cash or ACH discounts vary by card brand, state, and sometimes the type of transaction. Before changing your pricing or invoices, confirm the requirements with the card brands and your state. You can use the scenario slider to see how much it is worth to move customers off checks before deciding on any incentive.
Which business type should I pick if we sell subscriptions to other businesses?
Pick the one closest to your model: eCommerce for online self-serve plans, Professional services for retainers and managed services, or B2B for recurring product supply. The choice only sets the default card rate and the segment used in the illustrative estimate. Entering your actual effective rate from your statement gives a more useful result than any default.
