Enroll them once.
They pay you forever.
Customer signs once. Stripe bills them on cadence. The system books the maintenance, discounts the repairs, and renews itself.
You sold 40 maintenance plans.
The office books 4 of them.
The memberships were the easy part — customers sign up at the install. The hard part is the year after. The reminder calls nobody makes. The spring tune-ups that never get booked. The renewal that lapsed because someone forgot to invoice. A program that should print money turns into a stack of names in a spreadsheet.
One link.
One signature.
Send the customer a link. She picks the tier, signs with her finger, she’s enrolled. Stripe takes the first payment. Run A Call books the first service. Same pattern she already knows from signing the estimate.
No app to install. No portal to log into. The system does the work in the background while she lives her life.
