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	f02e86769b	Charge the price the website shows, and hand a withdrawal back in full ... Stripe was charging the catalogue's NET figure while the document added the domestic rate on top: a customer quoted 214,80 paid 179,00 and was then invoiced for VAT nobody had collected. Under para 11(12) UStG that VAT is owed to the tax office whether or not it ever arrived, so every document issued created a liability against revenue that did not contain it. The Stripe Price now carries the GROSS figure. price_cents stays net - it is frozen onto every contract and PlanChange prorates against it, so redefining it would corrupt every pro-rata sum ever computed. Only the amount at the till moved, and it is formed by the one call TaxTreatment already answers for the price sheet and for the invoice, so displayed, charged and invoiced cannot drift apart. Stripe's automatic_tax is deliberately not used. TaxTreatment is the single tax authority here, and a second rate computed by Stripe would take 19 % from a German consumer while our document said 20 %. A Stripe Price cannot be edited, so a changed figure means a new Price and the old one archived - which stops it being SOLD and leaves every subscription already on it billing the old amount for ever. stripe:reprice-subscriptions is the second half, and a command of its own because it touches live money. A withdrawing consumer is refunded in full, as the owner decided. That is more generous than FAGG para 16 requires, and it makes the express-request consent the statute hinges on irrelevant - so the gate is gone rather than left looking load-bearing.

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	3fb7e5f08c	Decide the VAT rate in one place, before the two disagree ... The Finance tab wrote a rate into settings while TaxTreatment kept reading one from config — two sources for one number, added by me two commits ago. It had not bitten yet only because both happened to say 20. TaxTreatment now takes the domestic rate from CompanyProfile, which falls back to the .env-derived config until an operator saves one. Same shape as ProvisioningSettings, which already solves this for the deployment values, and the same reason: an operator can change a settings page and cannot change a config value, so a page that appears to set the rate and does not is worse than no page at all. Reverse charge and the seller country stay where they are. That logic already existed, already handles a verified EU VAT ID correctly, and nothing here needed to know about it — which is exactly why it should not have been duplicated.

nexxo	5aef5e693c	fix(billing): verification vouches for a value, not for a row ... A timestamp alone said "some number was checked once": editing the field left it intact, so a customer could swap a verified foreign VAT ID for any plausible-looking one and keep zero-VAT pricing. The verified value is stored and compared, which makes the rule self-enforcing — no writer has to remember to clear a flag, and there are several writers.

nexxo	42ceafb57f	fix(billing): a self-declared VAT ID must not zero the tax ... Any non-empty string starting with two characters other than AT switched the customer to reverse charge — typing "XX123" was a 20 % discount. Reverse charge now requires a VAT ID that is verified, belongs to an EU member state other than ours, and looks like a VAT number at all. Unverified is the normal state and means the domestic rate: over-collecting is correctable, under-collecting is a tax liability. Changing the number clears its verification. Verification itself (VIES) is not built yet, so reverse charge stays off until someone confirms a number — which is the safe direction to be wrong in.

nexxo	76510a59a3	fix(billing): VAT follows the customer, not a global setting ... Codex was right that this could misstate real charges: an EU business with a VAT ID registered in another country is billed under reverse charge, and we were adding 20 % Austrian VAT to their total anyway. TaxTreatment resolves it from the customer's VAT ID, and the whole page — cart, plan cards, add-on cards — now states one treatment instead of contradicting itself. Explicitly NOT handled: cross-border sales to private individuals, which are taxed at the buyer's national rate under OSS. That needs a maintained rate table and a tax adviser, not a guess, so those fall back to the domestic rate — over-collecting rather than under-collecting.
