Card vs ACH vs Check: What Each Payment Method Really Costs Your Dental Practice

How a dental practice's payment mix differs from a typical invoicing business

Most dental revenue arrives through two channels. Patients pay their portion at checkout, mostly by card, including HSA and FSA cards, and mostly card-present. Insurance carriers pay the rest by EFT with an electronic remittance, by paper check with a printed EOB, or sometimes by a virtual card number. Mailed patient statements add another stream of checks and phone-in card payments, which are card-not-present.

That split matters for the inputs. When you set your shares, count insurance EFTs as ACH, payer and patient checks as check, and front-desk, online bill-pay, and virtual-card insurance payments as card. If you don't know your card effective rate, select Healthcare as your business type and the tool will use a default assumption of 2.65%. That figure is an industry-average estimate, not your actual rate. Your most recent processing statement will give you a better number: total fees divided by total card volume.

Staff minutes matter more here than in most businesses. A paper insurance check means opening mail, matching the EOB to claims, posting line by line, handling any adjustments, and preparing the deposit. An auto-posted ERA paired with an EFT can take a fraction of that time. Time a few of each at your front desk before you enter the minutes. Don't guess.

Worked example: a hypothetical general dental practice

Hypothetical inputs, for illustration only: $120,000 monthly revenue, $300 average payment, 40% card, 35% ACH, 25% check. Days to cash: 2 for card, 3 for ACH, 21 for check. Card rate: the 2.65% Healthcare default. Fees: $0.50 per ACH payment and $3 per check. Staff time: $30/hour, 1 minute per card payment, 2 per ACH, 6 per check. Cost of cash: 8% per year.

Results: card costs about $1,373 a month, almost all of it processing fees. ACH costs about $238. Checks cost about $740, split roughly evenly between out-of-pocket costs and staff time, plus carrying cost. Total cost is about $2,351 a month, or 1.96% of revenue. About $28,400 is tied up in collection, and weighted days to cash are 7.1.

Run the scenario slider to move 100% of check volume to ACH. Monthly cost drops by about $570, roughly $18,000 in cash is freed, and weighted days fall to 2.6. Moving the same checks to card instead frees about $19,000 but adds about $118 a month in cost, because the card fee at 2.65% outweighs the labor saved. For this practice, getting payers onto EFT is the cheaper fix. Card makes sense where speed and patient convenience justify the fee.

Estimates are based on published industry averages and are not a quote. Actual rates depend on card mix, ticket size, industry, and underwriting.

Seasonality, payment plans, and refunds in dental practices

Many practices see payment patterns shift during the year. Deductibles reset in January, so patient out-of-pocket card payments may rise early in the year. Patients trying to use remaining benefits can create a late-year treatment rush, followed by a wave of insurance payments. Run the tool on a slow month and a busy month to see the range, not just one snapshot.

Large cases change the math. Orthodontic, implant, and cosmetic treatment often involves deposits and multi-month payment plans. A plan billed to a card on file costs a percentage of every installment. The same plan on ACH autopay costs a flat fee per payment. If your average payment is $1,000 or more, the full report adds a section on large-ticket card pricing questions to raise with your processor.

Insurance overpayments and credit balances lead to patient refunds. Depending on your processor, the original card fee may not be returned when you refund to a card, so frequent refunds quietly raise your effective rate. If you are considering a surcharge or cash discount program to offset card costs, rules vary. Confirm with the card brands and your state before making changes, including how they apply to debit and HSA cards.

What a good result looks like for a dental practice, and junk fees to check

A healthy result usually means three things: a low check share, weighted days to cash in the single digits, and card costs concentrated where patients value the convenience. You won't reach zero checks, since some payers and patients will always mail them. But if checks are 30% or more of your volume, the full report adds an ACH/eCheck and virtual terminal setup checklist. That checklist helps you move statement payers to online payments.

If your calculated card cost looks high, compare it to your processing statement. Common fees that inflate dental processing bills include PCI non-compliance fees, monthly statement or minimum fees, batch fees, and non-qualified surcharges on tiered pricing. Annual fees and early termination clauses are also worth checking. The gated report includes an illustrative interchange-plus estimate for your card volume. It uses placeholder assumptions, not a quote and not TouchSuite's actual rates, and gives you a reference point for that conversation.
