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	f85f57152e	Let the customer buy it themselves, and tab the integrations page ... Every path on the site ended in "anfragen": a mailto: link and a promise to answer the same working day. That is an afternoon of somebody's time per customer, for a product whose whole point is that the machine does the work — and it scales exactly as far as one inbox does. Now: sign in, pick a package, pay, and provisioning starts by itself. The pieces were already there — Stripe holds a Price per plan version (the catalogue sync writes the ids), the webhook opens the contract, the pipeline builds the VM — and what was missing was the checkout session between them. CheckoutController opens one and gets out of the way; the purchase becomes real on the webhook, which stays the only place allowed to believe a payment happened. The success URL is a redirect target and therefore a URL anybody can type, so it says "we are building it", not "you have paid". Nothing in the request may decide the price. The plan key arrives from a form and everything else is re-derived from the catalogue, including the plan VERSION, so a version published while the customer types their card number cannot change what they were quoted. Two cases that are not errors: no capacity is a parked order (already built), and an existing customer is sent to the plan change rather than sold a second, empty cloud that bills twice. The site says what it can keep. "danach wissen Sie … wie Ihre Daten sicher umziehen" was a promise made before seeing the thing it is about: we do not know where a visitor's data is, what shape it is in, or whether it can be moved at all. Migration is named as its own question, looked at first and quoted afterwards. The integrations page gets the settings page's treatment for the same reason: it was one narrow column of six cards, so an operator connecting DNS scrolled past Stripe to reach it and the raw .env editor sat at the bottom of everything. Three tabs by what a section is FOR — services we buy from outside, our own machines, the file underneath — the same axis the page was rebuilt around when it stopped being split by storage mechanism. The tab is in the query string; unlocking survives a switch, because a confirmed password is a session fact and not a property of a tab. The .env tab is Owner-only, like the editor it holds.
