Tutoring and lesson studio vertical SaaS: prepaid package deferred revenue, breakage, and refund-liability ledger · Nov 2, 2026
CreditBook
A prepaid-package ledger that tells tutoring centers and lesson studios exactly how much they still owe families.
The problem
Tutoring centers cannot see how much they owe families for unused prepaid sessions, so deferred revenue and refunds are guesswork at year end.
The wedge
Scheduler-agnostic accounting layer using a read-only Stripe key plus an attendance CSV to output a monthly liability report and QuickBooks journal CSV.
