How test prep services get paid
Test Prep Services run tuition on recurring billing, take enrollment deposits by card, and accept ACH for larger balances, all through Flux.
A typical Flux setup for test prep services
Test prep money moves on the exam calendar. Course enrollment concentrates in the eight to ten weeks before major test dates, so revenue arrives in waves: a card deposit reserves the seat when the schedule posts, and the balance is charged before the first class or split into installments that finish before test day. Private hourly coaching runs on a stored card between waves, and diagnostic exams are small one-time card charges.
The payer and the student are usually different people: a parent's card funds a teenager's SAT course, while a graduate funds their own bar or licensing prep, sometimes on a payment plan. Programs running many cohorts at higher volume qualify for volume discounts through custom interchange-plus pricing. Settlement is simple: cards in 1-2 business days, ACH in 1-3 for larger package invoices, and everything reconciles through the QuickBooks sync by course and cohort.
What test prep services should watch
Score guarantees are the industry's signature refund risk. A guarantee written loosely, higher score or your money back, invites claims you cannot verify. One written precisely, with attendance, homework completion, and an official score report as conditions, is enforceable and rarely invoked. Collect agreement to those conditions at checkout, not in a PDF nobody opens. A refund you issue under your own guarantee is a controlled cost, and a chargeback from an angry family is not.
Installment plans need to outrun the exam. A plan that still has payments due after test day collects poorly once the score is in, whatever it was, so schedule the final installment before the course ends. Watch withdrawal timing too: a student who drops two classes in expects a different refund than one who drops after the midpoint, and a published proration table at enrollment settles that conversation before it starts.

What does Flux charge test prep services?
A flat 2.9% plus 30 cents per transaction, with volume discounts for higher-volume merchants and no setup fees or contracts. Accounts processing under $100,000 a year in card volume may be subject to a $20 monthly account fee. You can also pass the processing fee to the customer at checkout where local surcharging rules allow.
How fast do test prep services get their money?
Card payments settle in one to two business days and ACH in one to three business days. Stablecoin payments go to your wallet instantly.
How should we time installments for a course that ends on test day?
Schedule the final installment to clear before the last class session, not after the exam. Collections get harder once scores are out, and a plan that finishes early avoids the problem entirely.
Does honoring a score guarantee refund count as a chargeback?
No. A refund you issue voluntarily is just a refund, and it never touches your dispute record. Chargebacks only happen when the cardholder goes to their bank, which a clear, honored guarantee makes far less likely.
Can we take a deposit when enrollment opens and the balance closer to the course?
Yes. Charge a card deposit to hold the seat when the schedule posts, then bill the balance or start an installment plan on the stored card before the first session. Both charges carry the same flat 2.9 percent plus 30 cents.
