Revenue infrastructure you'd otherwise have to build.
Selling education across borders is a payments problem, a tax problem and an accounting problem. Course Engine ships the whole layer — built for real order volume in real currencies.
Book a demoAn invoice ledger built for audits.
Every invoice is chained to the previous one with a cryptographic hash, numbered without gaps, and frozen at issue.
- Tamper-evident: any modification to a recorded invoice is detectable by construction
- Database triggers reject updates and deletes on issued invoices outright
- Refunds mint negative credit notes with prorated tax — the ledger never rewrites history
- Order financials freeze the moment they're invoiced
Orders, subscriptions, memberships.
Order lifecycle
An eight-state lifecycle including SEPA processing; every status change is written by the database itself, so no code path can skip the audit trail.
Subscriptions
Trials, grace periods, dunning reminders on a five-minute cadence, and first-class installment plans that close themselves when paid.
Memberships
Tiered membership products with per-tier content gating and localized offer pages.
Partial refunds
Per-transaction refunds live against Stripe and PayPal, reflected on the order and the credit-note ledger.
Coupons & promotions
Percentage or fixed, per-customer caps, first-purchase-only, auto-apply, scheduled promo banners with per-locale copy — plus per-product order bumps at checkout.
Agentic commerce
A signed machine-to-machine checkout (UCP) with per-tenant keys — built for the next wave of AI shopping agents.

- Currency resolution from subscription lock, visitor choice, purchase history or geography — in that order
- Zero-decimal currencies handled correctly across 16 cases
- Self-computed, compound-aware taxes — region-exact rules beat country rules, itemized per order
