Credit Card and ACH Payments for Medical and Dental Practices in Tennessee

Quick answer: how should a Tennessee practice split card and ACH payments?

Most medical and dental practices in Tennessee use ACH for predictable, lower-cost transfers, like paying a payroll processor, a lab, or a landlord, and use a credit card for vendor bills where the extra time before the card is due matters more than the small percentage fee. A billing or office manager at a two-location practice in Franklin, Tennessee, for example, might run supply orders and equipment leases through a card to stretch the payment window, while sending rent, insurance premiums, and recurring lab fees through ACH because those amounts rarely change and speed isn’t the priority.

ACH moves money directly between bank accounts and is built for stable, recurring bills. A credit card works more like a short-term line of credit on every payment, which helps when a supply invoice lands before the month’s patient collections have cleared.

Why a practice’s billing team needs both payment rails

A dental or medical office runs on uneven cash flow. Patient payments, insurance reimbursements, and Medicare/Medicaid deposits land on their own schedule, but supply vendors, equipment lessors, and lab partners bill on theirs. A billing manager who can only pay by ACH has to wait for the bank balance to catch up before sending money out. A billing manager who can only pay by card pays a transaction fee on every single bill, even the predictable ones that don’t need the float.

Using both lets a practice match the payment method to the bill. Zil Money’s ACH payment tools handle the recurring, lower-cost transfers, while its credit-card-funded vendor payment option covers the bills where extending the payment date is worth a small fee.

How credit card vendor payments work for a dental or medical practice

A practice can charge a credit card for a vendor bill even if that vendor, like a dental supply distributor or an equipment lessor, doesn’t take cards directly. Through Zil Money’s credit card vendor payment tool, the card is charged and the vendor is paid through ACH, check, or wire, whichever it already accepts. The practice earns whatever rewards or cash back its card offers, and the card statement isn’t due for roughly 30 to 45 days, depending on the card’s billing cycle. That gap gives a billing manager time to let insurance reimbursements and patient payments come in before the card balance is due.

The fee for this service is 2.9% per card-funded transaction, with no setup fee and no monthly charge. For a $2,000 supply order, that’s about $58. Whether that fee is worth paying depends on the math: if the extra 30 to 45 days keeps the practice from dipping into a line of credit, or if the card’s rewards rate offsets most of the fee, it can make sense. For a bill the practice could pay from cash on hand today, ACH or a direct transfer is usually the cheaper option.

Step-by-step: paying a supply vendor by credit card through Zil Money

1. Log in to the Zil Money account and open the vendor payment or bill pay screen.
2. Enter the vendor’s name and payment details, or select the vendor from a saved list if the practice has paid them before.
3. Choose the payment amount and select a credit card as the funding source.
4. Pick how the vendor should receive the money, based on what it already accepts.
5. Review the 2.9% fee shown before confirming, then submit the payment.
6. Zil Money charges the card and sends the vendor payment on the selected delivery timeline: typically 1 to 3 business days for ACH, 3 to 5 business days for a mailed check, or same-day and overnight options for urgent bills (subject to rail availability and bank cutoff times).

Where ACH fits a practice’s regular bill run

ACH payments move directly from the practice’s bank account to the recipient’s, without a card fee attached. Standard ACH transfers typically settle in 1 to 3 business days, and Same Day ACH can post on the same business day it’s sent. That makes ACH a good fit for payroll, rent, insurance premiums, equipment lease payments, and any lab or vendor bill that’s the same amount every month.

The Federal Reserve describes the ACH network as a nationwide system that lets banks send each other batches of electronic credit and debit transfers, covering both recurring payments like direct deposits and one-time transactions such as converted checks and phone or internet payments. That’s the same rail Zil Money’s ACH tools run on, which is why it works well for a practice’s steady, repeatable bills.

What HIPAA-adjacent means for a practice’s payment platform

Billing and office managers are often the ones asked whether a new payment tool is “HIPAA safe,” since it touches data connected to patient accounts even when it’s not clinical data. Zil Money’s platform carries its own HIPAA, PCI DSS, and SOC 2 certifications, plus SOC 1, ISO 27001, ISO 20000, ISO 9001, CCPA, and NIST 800-53, and the company is a NACHA member for its ACH processing.

They don’t make the practice itself HIPAA compliant. A practice’s HIPAA compliance depends on its own policies, staff training, business associate agreements, and how it handles protected health information across every system it uses, not just the payment tool. A billing manager evaluating a payment platform should treat these certifications as one input, not a substitute for the practice’s own compliance program.

Cash flow timing: what a Tennessee practice’s billing manager should watch

Timing is where the two rails matter most. ACH and Same Day ACH both draw from the practice’s bank balance right away or within a few days, so the money needs to already be there. A credit card payment doesn’t touch the bank balance until the card statement comes due, roughly 30 to 45 days later. Zil Money notes that same-day or within-minutes delivery for certain payments can shift with payment rail availability, the bank’s cutoff times, and the recipient’s own bank processing, so a billing manager should confirm delivery timing for a specific payment rather than assume it every time.

A practice with predictable collections, like one that runs mostly insurance business with reliable reimbursement timing, can lean more on ACH since the cash is usually there when the bill is due. A newer practice, or a multi-location dental group expanding around the Nashville area, may lean more on the card float for larger supply or equipment bills, then shift back to ACH once collections stabilize across every location.
