nexxo	8440266ed3	Stop charging for a service that has ended ... Nothing in this application could cancel a Stripe subscription — there was no such method on the client at all. So a customer who cancelled and a consumer who withdrew both stayed subscribed, the card went on being charged every month, and every one of those payments arrived as invoice.paid, drew a real number out of the gapless Austrian series and mailed the PDF, for a machine that had been switched off. Indefinitely. StripeClient::cancelSubscription() closes the first half, with the timing passed explicitly at the call site — CANCEL_AT_PERIOD_END for a cancellation, because the customer keeps the term they paid for, and CANCEL_IMMEDIATELY for a withdrawal, because that unwinds the contract and the whole amount has just gone back. The immediate form states prorate and invoice_now as false rather than inheriting them: a credit note of Stripe's beside our own Storno would be the same money twice. The second half is ApplyStripeBillingEvent::owesADocument(). Refusing every invoice on a cancelled contract would lose the legitimate final one — the cycle for a term the customer really did use, unpaid, dunned for three weeks and settled after the contract ended. So the question is not when the payment landed but what it is for: an invoice whose billed period STARTED before the contract ended is documented, one whose period begins at or after that moment is not. Neither is a contract marked cancelled with no date, nor an invoice with no period, because a number handed out in error can never be withdrawn while a missing document can still be issued. The register entry is written either way — the money moved, and that is where an operator finds what has to go back. A cancellation also took its date from the order date plus MONTHS, whatever the term said, so a yearly customer who cancelled in March lost the nine months they had already paid for. It reads current_period_end now, which Stripe keeps current for both terms; the month-walk survives only for a machine with no contract behind it, where nothing records a term at all. Stripe is asked first and our rows are written only if it agreed: a cancellation we could not make effective is the defect above wearing a "gekündigt" label on the settings page, and a cancellation has no deadline, so being asked to try again costs nobody anything. A withdrawal cancelled the OPENING invoice only, found by invoices.order_id — which a renewal and a module document leave null on purpose. A storage pack booked on day three and withdrawn from on day ten was therefore neither cancelled nor refunded. Every charge inside the window is covered now, one Storno per document and one refund per payment, each against the payment that actually took it: a single refund of the total against the opening PaymentIntent is what Stripe would have refused for exceeding it, and one idempotency key for the whole withdrawal would have had Stripe replay the first refund's answer for the second. StartCustomerProvisioning::resume() opened a missing contract and returned, and the only production call to IssueInvoice::forOrders() is after the order commits — so a worker killed in between cost that customer their invoice for good, silently, with nothing anywhere sweeping for it. resume() finishes that work too, guarded by the invoice already filed against the order and by invoices.sent_at, so however often Stripe redelivers it comes out as one invoice, one number, one mail. The order confirmation stays on the first pass alone: it has nothing to stamp. subscriptions.cancel_requested_at is new because the billing half of the application had no way to tell a cancelled contract from an untouched one. Deliberately not a status: until the term runs out this is a paying customer, which is the distinction EndInstanceService is built around, and `cancelled_at` beside it still means the day it genuinely ended. clupilot:verify-vat-ids is scheduled monthly on the first, and its docblock no longer points at a note in routes/console.php that never existed. Reverse charge rested on a one-off VIES answer, a withdrawn registration keeps earning rate 0 for ever, and the unpaid VAT on those invoices is the seller's — so the cadence is the width of that window, and the first of the month is the rhythm the return is filed on. Two tests that proved nothing are now about behaviour. SettingsTest asserted service_ends_at was not null, a column the code had just written and which the broken monthly arithmetic satisfied exactly as well as the right answer; it states the yearly date, the contract's own record and the order to Stripe. EndInstanceServiceTest travelled to whatever value the implementation had computed, so it recomputed the code instead of checking it, and never looked at billing at all; the boundary is a literal date now and the money stopping is asserted beside the address coming down.

nexxo	2277dfe4cb	Ask the EU register whether a VAT number is real ... vat_id_verified_at was declared on the customer and read by TaxTreatment, and set by no code anywhere. hasVerifiedVatId() therefore never returned true, so reverse charge could not trigger for anybody - and every EU business customer was invoiced Austrian VAT they cannot reclaim in their own country, which is not a pass-through for them but a real cost until the invoice is corrected. The check has THREE outcomes, and the third is why VatIdCheck exists. VIES is a gateway onto twenty-seven national registers and any of them is regularly down. Reading "I could not ask" as "not registered" would clear a verification that has stood for months, move that customer onto the domestic rate, and change what their next invoice says - because a register was asleep. Reading it as "registered" would put reverse charge on an unchecked number, which is our liability. So on UNAVAILABLE nothing at all is written. Asked at the moment the number is entered, because that is when somebody is looking at the field and can fix a typo. The save has already happened by then and the check cannot undo it: a register that is down must not cost a customer their address change. Shape and membership are refused before a request is spent, and the fake refuses on the same rule as the real verifier. A fake that answers where VIES would never have been asked is not a simplification but a different product, and free text normalises into a well-formed number more easily than it looks - "not a number" becomes NOTANUMBER, which the shape rule alone reads as a Norwegian one. clupilot:verify-vat-ids re-asks about the numbers reverse charge rests on, since a registration can be withdrawn. Deliberately not scheduled: it queries a public service with a concurrency limit on behalf of somebody else's tax position, and the cadence is the owner's to set.
