nexxo 9da1358802 Stop charging VAT to the customers who owe us none
A verified EU business outside Austria gets reverse charge — rate 0, no VAT
line, the note on the invoice — and was still charged 214,80 € for a 179,00 €
package, because one Stripe Price carried the domestic gross for everybody.
There is no VAT line on their document to reclaim, so it was a flat 20 %
surcharge on exactly the customers who read their invoices, and the document
then stated the whole 214,80 € as net at 0 %, so they self-accounted their own
VAT on a base a fifth too large.

A Stripe Price can ask who is buying after all: there are two per sellable
thing now, the domestic gross and the bare net, both live on one Product, and
the checkout picks by TaxTreatment. The rule is Austria B2B 20 %, other EU B2B
without VAT — a domestic business still pays the gross, reclaims it as input
tax, and the price on the website is still the price charged for them.

- stripe:sync-catalogue mints and archives both halves of every pair, per plan
  and per module; `reverse_charge` on stripe_plan_prices/stripe_addon_prices
  says which is which, and joining it on subscriptions.stripe_price_id says
  which one a running contract is billed on. A rate change moves the gross
  Price and leaves the net one alone, because the net owes nothing to the rate.
- A status that changes after the sale converges: a verification (or a lapse)
  makes stripe:reprice-subscriptions move the contract onto the other Price
  with PRORATE_NONE, because the term is already paid for. The module items
  follow the same way.
- Downstream follows: the invoice total equals what was taken, the proof
  register expects the figure this customer is actually charged (so a correct
  reverse-charge sale is no longer flagged as a mismatch, and an overcharged
  one is), the setup fee obeys the same rule, and the booking page quotes what
  it will charge.
- StripeClient gained activatePrice(). Archived Prices were brought back in our
  own table and left inactive at Stripe, so a rate that moved and moved back
  pointed the catalogue at a Price no checkout could be opened for.

An unverified number is still charged the gross — an unchecked string must
never be a discount — and where the net Price is missing the checkout refuses
rather than reaching for the domestic one.

nexxo 8ca0d4d257 Say the same thing to the customer, the register and the bank
tests / pest (push) Failing after 8m5s Details
tests / assets (push) Successful in 25s Details
tests / release (push) Has been skipped Details
Five places where the product told somebody a figure that nothing behind
it produced.

**The invoice page showed five invoices nobody was ever issued.** A mock
that outlived its purpose: CP-2026-0003 to CP-2026-0007, a prefix
belonging to no configured series, all "paid", a spend curve from 179 to
198 € and a next charge of 198 € on 01.08.2026 — behind
['auth','verified','customer.active'], so every signed-in customer saw
it. Their real invoices existed in `invoices`, were rendered as PDFs and
mailed to them, and appeared nowhere in the portal at all. The page now
lists their own documents, newest first, with the numbers, dates and
totals off the frozen snapshot, a Storno marked as one, and a download.
The PDF route resolves the document against the signed-in customer in
the query — a URL anybody can type is not made private by not printing
it. No next charge and no chart: nothing here computes what Stripe will
take next cycle, and a figure nobody has worked out is worse than a
blank space.

**The setup fee was quoted everywhere and charged nowhere.** On the
price sheet, on the booking page, set by the operator in the console —
and CompanyProfile::setupFeeCents() had no reader outside the two
sentences that quoted it. It is charged now, as a second non-recurring
line on the same checkout session, which Stripe puts on the initial
invoice only. `orders.setup_fee_cents` records how much of the charge it
was, so the whole total still goes back on a withdrawal while the
register holds the PACKAGE's charge against the contract price and the
invoice prints the fee as a line of its own. The booking page was also
quoting the fee NET under the same sentence the website quotes GROSS —
99,00 against 118,80 — and now quotes what will be taken.

**An upgrade click cancelled a booked downgrade and delivered nothing.**
Nothing in this application marks a cart order paid, so the customer
traded a downgrade they had genuinely booked for a cart line that would
never be fulfilled. The booking now stands until the upgrade actually
lands on the contract, where ApplyPlanChange clears it. The fulfilment
seam is reachable for every type that can be paid — a module and a
storage pack book through BookAddon, which was the missing path from a
paid order to a SubscriptionAddon and left AddonPrices,
SyncStripeAddonItems and clupilot:end-cancelled-addons with no caller
behind a payment. A paid traffic pack logs an error rather than pretending:
the metered allowance is a standing count of packs while a top-up is sold
for one month, and which of the two is meant is not a guess to make here.
That no path to `paid` exists yet is now stated in both places rather
than in one.

**The proof register called correct charges wrong.** expected_gross_cents
used the CUSTOMER's rate, which is zero under reverse charge, against
the domestic gross Stripe actually took — so matches_catalogue was false
for every EU business sale charged exactly the advertised amount, and
for every renewal on a contract with a module, which was held against
`price_cents` alone. It compares against TaxTreatment::chargedCents()
and against the whole term now. Where no money moved, charged and the
flag are null instead of the expected figure agreeing with itself, and a
plan change records the terms with the pro-rata figures in the snapshot
rather than money that arrives again on Stripe's proration invoice.

**The seller's own VAT id was on the invoice, unlabelled**, between the
register number and the court. Labelled — and the footer's composition
moved out of the TCPDF method, because inside one the only way to read
what it says is to render a PDF and un-subset its fonts.

One test enshrined a figure the code does not produce: a reverse-charge
purchase recorded with no charged amount, asserting 17900/0/17900, where
OpenSubscription always passes the charged figure and a real one records
21480/0/21480. Another asserted that an upgrade click cancels a booked
downgrade.

Full suite: 1676 passed.

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.

tests / pest (push) Failing after 8m35s Details
tests / assets (push) Successful in 22s Details
tests / release (push) Has been skipped Details
Three things the product owed its customers and did not have.

**Who is on the other side.** There was no consumer/business flag anywhere,
and `vat_id` was standing in for one — which it cannot: a business without a
VAT number is an ordinary small business, and a consumer with one does not
exist. It is asked at sign-up now, correctable in the portal, and NULL where
nobody has been asked. Unknown is read as CONSUMER everywhere it decides a
right, because that mistake costs us a refund while the other one takes a
statutory right away from somebody who has it.

Reverse charge asks the recorded type instead of the number: an explicit
consumer is charged the domestic rate whatever `vat_id` says — previously they
were not, and anyone could zero their own VAT by getting a number verified. An
unrecorded type still falls back to the verified number, so no contract that is
already running changes rate.

**The fourteen-day right of withdrawal** (FAGG, §312g BGB), for consumers only,
at every door: the window is stamped on the contract when it is concluded, the
customer exercises it from the portal, an operator records one that arrived by
telephone or post, and both go through one action that refuses a business
customer on the server rather than by hiding a card.

The money follows the paperwork rather than being computed beside it. The
invoice is cancelled by a Storno with its own gapless number — nothing is ever
edited or deleted — a new invoice states the pro-rata value of the service
actually delivered (FAGG §16, by days over the term paid for), and the refund
is exactly the difference between the two documents. Where the consumer never
expressly asked for the service to begin at once, they owe nothing and the whole
amount goes back. `StripeClient::refund()` is new, keyed so a retry cannot send
the money twice. The service ends through EndInstanceService and the
`cancellation_scheduled` machinery that was already there.

**The cancel button for modules.** BookAddon::cancelAtPeriodEnd() had no caller
in the interface at all, so a customer could book a recurring charge in two
clicks and had no way to stop it. It is on the module card now, with the date it
runs until and a way back while the cancellation is still pending — and putting
a module back settles nothing, because the term it was cancelled for was paid
for in advance.

nexxo 8f1630ba91 Bill a booked module every month, and put it on the invoice
A module was never an item on the Stripe subscription, so it was charged in
the month it was booked and never again. And the renewal document was written
from our own contract snapshot, so it would not have said so even if the money
had been taken. Two halves of one fault, closed together.

Modules are items now. stripe:sync-catalogue mirrors a Product and a Price per
module on both terms — a Stripe Price carries its own interval, and a booking
frozen at an older figure needs its own Price, so they are keyed by module,
amount, currency and interval in stripe_addon_prices. Booking adds an item with
always_invoice: prorated by days AND charged there and then, which is the
invoice the owner wants for a module booked mid-term. A second storage pack is
a quantity on one item, not a second item. Cancelling takes the item off with
no proration — no credit, and the next cycle is simply smaller — while the
module itself is kept until the period end on subscription_addons.cancels_at
and ended by clupilot:end-cancelled-addons.

Documents are built from Stripe's own invoice lines. Stripe is what charged the
customer; a document assembled from our figures would state a sum that is not
the one taken. So every paid Stripe invoice gets one document with one number,
idempotent on stripe_invoice_id — a cycle carrying package and every module
together, a mid-period booking carrying just its prorated line, an upgrade
carrying its proration. Only the wording is ours: each line is named from the
catalogue rather than printed as a Price id, and a line nobody can name stays on
the document under Stripe's own description and is logged. The checkout's own
invoice is still the one exception; that purchase already has a document.

Stripe being away never undoes a booking that has already reached the machine.
The failure is parked on the contract in stripe_addon_sync and swept by the
same clupilot:sync-stripe-subscriptions that retries a plan change, which finds
its work from the bookings themselves rather than from the marker. A granted
contract has no Stripe subscription and is not touched at all.

nexxo 35b312d5ef Invoice every renewal, and tell Stripe when the package changes
Two things Stripe was doing on its own, without us.

**A renewal produced no invoice and no mail.** InvoiceMail went out from
exactly one place — the first purchase — so a customer paying every month
for a year received one invoice, for month one. Stripe already says when
the money lands: invoice.paid with billing_reason subscription_cycle. What
was missing was the document.

A renewal has no Order behind it, and one was not invented for the
occasion: an Order is something a customer bought, and writing a purchase
nobody made would corrupt the record of what they have actually ordered.
IssueInvoice::forBilledPeriod() issues from the CONTRACT instead, at its
frozen net price, for the term Stripe billed. Idempotent against the Stripe
invoice id, which is unique in the database rather than checked in PHP —
and because the number is drawn inside the same transaction as the row, a
redelivery takes its number back with it and the series keeps its sequence.
Nothing in the paperwork can fail the webhook: issuing and mailing are both
caught and logged, exactly as confirmByMail() does.

Only a cycle renewal gets a document. The checkout's own invoice already
has one; an upgrade's proration was worked out against Stripe's boundaries
and would not match a document written from our snapshot; a charge raised
by hand is for something this catalogue cannot describe. All three stay in
the register, and are logged once as money no document of ours covers.

**After a plan change, Stripe went on billing the old price.** There was no
way to move a subscription onto another price at all, so a customer who
upgraded paid for the smaller package every month afterwards. The client
can now swap one, the item id it needs is learnt from Stripe's own events
(and asked for once, for contracts older than the column), and the
behaviour is chosen per direction: an upgrade settles immediately, so the
cycle invoice stays exactly the contract price the renewal document states;
a downgrade lands at the period boundary and settles nothing.

A granted contract has no Stripe subscription and is left untouched. A
change that reaches the machine and not Stripe is never rolled back — it is
parked on the contract with the error and the behaviour it needed, logged
as an error, and retried hourly by clupilot:sync-stripe-subscriptions.

Claude a58faf3f85 Manage the Stripe key from the console, behind a password and a test
tests / pest (push) Successful in 8m56s Details
tests / assets (push) Successful in 20s Details
tests / release (push) Successful in 4s Details
Changing a key meant a shell, a file edit and a cache rebuild — and the person
who owns the Stripe account is not necessarily the person who owns the server.

Two gates, not one. The capability decides who may open the page; every operator
has console.view, and that must not mean "can read the payment key". The
password decides whether this SESSION may see or change anything, because the
realistic threat is not a stranger but an unlocked machine, and a session is
exactly what that hands over. Both are re-checked server-side on every action —
a Livewire action is reachable by anyone who can post to /livewire/update.

The value is stored encrypted under a key of its own, SECRETS_KEY, and the vault
refuses to work without it rather than falling back to APP_KEY: rotating APP_KEY
is ordinary maintenance and would otherwise destroy every stored credential,
discovered when Stripe stops answering. It is read where it is used, not
overlaid onto config at boot — an overlay adds a query to every request
including the public site, and leaves queue workers holding whatever was true
when they started. It is never shown again, only outlined, and never enters a
Livewire property that would carry it to the browser and back in the snapshot.

A registry, not an env editor: a form that can set any environment variable is a
privilege-escalation primitive, and one bad value bricks the installation with
no way back through that same form.

The test button is the part that matters. It reports which Stripe account the
key belongs to, whether it is LIVE or test — the most expensive mistake here is
pasting one where the other belongs, and both look identical in a form — and
which webhook endpoints exist with the events each subscribes to. A key can be
perfectly valid while the endpoint listens for the wrong five events, and
nothing fails until a payment goes unrecorded.

The webhook signing secret deliberately stays in .env. It is read on every
incoming payment event; in the database, a database problem becomes silently
failing signature checks.

nexxo 0560ae743d feat(billing): Stripe owns the billing cycle, we own capability
A Product per plan family and a Price per priced row of a published version,
plus the four subscribed webhook events that were arriving and being ignored.

`stripe:sync-catalogue` mirrors the catalogue. Idempotent twice over: a stored
id is skipped, and each call carries an idempotency key derived from our own
row, so a crash between Stripe creating a Price and us recording its id gives
back the same object rather than a second one. That matters more here than
usual — a Stripe Price cannot be edited or deleted, so a duplicate is
permanent. Drafts are not synced at all: a version that has promised nothing
has no business in a price list. --dry-run shows what would be created.

The webhook now handles invoice.paid, invoice.payment_failed,
customer.subscription.updated and customer.subscription.deleted. It never
re-derives an amount: the invoice is the authority for what was charged, and
recomputing it from our catalogue would produce a second, disagreeing answer.
A failed payment is recorded and nothing else — Stripe runs the dunning
schedule, and cutting a customer off on the first failure would punish an
expired card as though it were a refusal to pay.

Only a cycle renewal moves the term on. Stripe also sends paid invoices for
prorations and manual charges, and the checkout's own invoice — which is
already in the register as the purchase, and would otherwise double every
customer's first payment.

Stripe does not guarantee delivery order, which is the source of most of the
care here:
- state changes are judged and written in one transaction with the row held,
  so two deliveries cannot both pass a check made on a stale copy;
- an older event never overwrites a newer one, with a rank breaking ties
  between events sharing a second — their timestamps have one-second
  resolution, and a failed attempt and its successful retry routinely do;
- a term is never shortened, and an ended contract is never revived;
- an event for a contract that does not exist yet is HELD and replayed the
  moment it appears, rather than acknowledged and forgotten. A cancellation
  dropped that way would leave us serving someone who had already left. Held
  rows that never match are pruned after a week.

Register entries are keyed by what they are about — the invoice, the attempt,
the subscription — with a unique index doing the work, because a check two
concurrent deliveries can both pass is not idempotency.

PlanChange is now documented as the preview shown before someone confirms, not
the invoice: Stripe's proration accounts for tax, existing credit and the exact
second the change lands, and ours cannot.

Not run against the live account — `stripe:sync-catalogue` creates objects that
cannot be deleted, so that is the owner's call. The dry run lists 12.

457 tests green. Codex review clean after seven rounds.
