nexxo	8ca0d4d257	Say the same thing to the customer, the register and the bank ... 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-07-30 01:30:24 +02:00
nexxo	6d7c2bdf35	Ask whether they are a consumer, and let one change their mind ... 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-07-29 20:22:02 +02:00
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.

nexxo	cd54212b34	Issue an invoice from what somebody bought, and freeze it there ... One invoice per purchase rather than per order: a customer who buys a plan and two add-ons in one go has bought once, and three invoices for one purchase is three times the paperwork for the same money. Each order becomes a line, which is also how the add-ons get listed individually. Everything the document says is copied into the snapshot at the moment the number is assigned — issuer, recipient, lines, rate, the reason for the rate. A test changes the company name and the customer name afterwards and asserts the invoice still says what it said. That is the whole reason no PDF is stored. The number and the invoice commit in one transaction. A number taken and then lost to a failure is a gap in a series that must not have one, and the refusal test asserts that a rejected invoice leaves the counter where it was. It refuses outright until the company details are complete. An invoice without a registered name, an address or a VAT number is not a valid invoice here, and issuing one consumes a number that can never be handed out again. VAT comes from TaxTreatment, which already existed and already handles a verified EU VAT ID correctly — including the reverse-charge note, without which a zero-rated invoice says nothing about why no VAT was charged. The billing address is carried as the lines it was written as. It is one free-text field today, and guessing which line is the postcode would put it where the street belongs, on a document nobody can correct afterwards.

nexxo	4646880b90	Print every line at full price and take the discount off once, in euros ... Second correction to the same block, and this one came from the right place: a line reading 202,50 beside "Rabatt 10 %" does not say whether the discount is in that number or still to come. It was unreadable, and unreadable on the one figure a customer checks. Lines are at full price now. Discounts are still entered per line — that is where they belong and where somebody decides them — but they are summed and shown once, in euros, under a subtotal that the "Gesamt netto" column adds up to. Subtotal, one subtraction, VAT, total: a sum anybody can follow without being told which figures are already adjusted. The gross line-total column is gone and a gross UNIT price takes its place. Full-price gross totals would sum to 315,60 against a total of 288,60 — the same contradiction in a different column. Nobody adds up unit prices, and a consumer reading this wants to know what one of the things costs. lineTotal() and adjustmentLabel() went with it. Nothing calls them any more, and a helper kept for a layout that no longer exists is the next person's wrong turn. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-07-29 01:59:56 +02:00
nexxo	d21e4f0eb2	Put a discount on the line it belongs to, so the columns add up ... With one discount applied under the table, the gross column summed to 315,60 against a total of 284,04. Nothing was miscalculated — the discount simply came after — but a reader who adds up a column found a document that does not agree with itself, and no way to tell which figure was the real one. On an invoice that is not a presentation detail. A discount or surcharge now sits on its line, percentage or fixed amount, and is inside that line's total. The label under the line is built from the same value that did the arithmetic, so the words cannot end up describing a different number than the one printed beside them. The invoice-wide adjustment stays in the arithmetic for anything that genuinely applies to the whole document, but nothing uses it by default.

nexxo	c1896e70fc	Render an invoice, with the arithmetic held to integer cents ... TCPDF 6, deliberately, after installing 7 and finding out what it is. Version 7 is not a newer TCPDF; it is a compatibility shim over tc-lib-pdf whose own mapping table lists 115 of 293 methods as stubs, and whose font package ships no font files at all — the first render died on a missing helvetica.json. The 6.x line carries a hundred and sixty-five fonts, a working writeHTML and real header and footer hooks, and is what everybody means by TCPDF. The body is a Blade template handed to writeHTML rather than a hundred Cell() calls with millimetre coordinates, because this table has to be adjusted the first time somebody sees it on paper, and nobody adjusts the second kind. InvoiceMath is integer cents end to end, and rounds once. A percentage applied line by line and rounded each time drifts from the same percentage applied to the sum — three lines at 3,33 € less 10 % is 99 cents that way and 100 cents the honest way, and the customer's calculator is what finds it. Gross is always derived from net and never the reverse: taking VAT back out of a gross figure returns a different number often enough to matter. A discount and a surcharge are one operation with opposite signs, so nothing has to remember which of two flags means which. Quantities are thousandths, because hours, gigabytes and part-months are all real, and are printed with the trailing zeroes stripped — "12,000 Std." reads as a defect. Every line shows quantity, unit price net, total net AND total gross: this goes to businesses and to consumers, and each reads a different column first. Verifying it took two goes and both failures were mine. `strings` over a PDF set in a Unicode font finds nothing, because the text is stored as subset glyph ids — the check has to render in a core font to be a check at all. And two of the strings I then declared missing were simply expectations I had got wrong. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-07-29 01:41:46 +02:00
