Spain, Portugal, France, Germany and Italy all require approved invoicing or till software, and the Gulf is building e-invoicing mandates of its own. So, plainly: Ontabee holds no fiscal-software certification, approval or accreditation in any country, and has built no country-specific adapters. Here is what the rules require, what we have instead, and what that means if you are deciding whether to use us.
No certificate, no approval number, no accreditation, no place on any national register — in any country. Where a regime requires approved invoicing or cash-register software, Ontabee is not that software, and we will not be the ones to tell you otherwise.
Not for Spain, France, Portugal, Germany, Italy, Greece, the UAE, Saudi Arabia, India or the United Kingdom. What the platform has is one general-purpose record chain that behaves identically everywhere, with no national signature and no transmission to any tax authority.
Nothing about using Ontabee alters what you owe, what you file, or when. What it changes is what you can put in front of someone who asks what came through your ordering channels — and that is a genuinely useful thing, but it is a different thing.
Nothing on this page is tax or legal advice, and it is not a substitute for your accountant. It is a statement about our own product, plus dated, sourced summaries of rules that change — confirm anything you are relying on.
Ten markets where operators most often ask us. Every row checked on 15 August 2026.
| Country | What the rules require | Where Ontabee stands |
|---|---|---|
| United Kingdom | No fiscalisation regime. No approved-software list exists. Separately, possessing a sales-suppression tool is penalised up to £50,000. HMRC consulted on mandatory EPOS/MPOS software standards between 23 June and 18 August 2026; nothing is legislated. | No approval exists to hold |
| Spain | Veri*factu. Invoicing software must produce hash-chained, unalterable records and either transmit them to the AEAT or hold them verifiably. Obligation starts 1 January 2027 for corporate taxpayers and 1 July 2027 for the self-employed, after two postponements. | No adapter |
| Portugal | Billing software must be certified by the Autoridade Tributária, and print an ATCUD code plus a QR code on every document. Certified software is required above €50,000 turnover or 1,000 invoices a year, and applies to foreign businesses VAT-registered in Portugal too. SAF-T billing files are reported periodically. | No adapter, not AT-certified |
| France | Cash-register software must be certified NF525. Since 1 September 2025 only certification issued by AFNOR or LNE counts — a publisher’s own attestation no longer does. Non-compliance carries a €7,500 fine per system. | No adapter, not NF525-certified |
| Germany | Kassengesetz and KassenSichV: an electronic till must be protected by a certified Technical Security Device (TSE), with no transition periods remaining, and each till must be reported to the tax office via ELSTER. | No adapter, no TSE |
| Italy | Sales must be recorded on a certified telematic recorder (registratore telematico), which seals each receipt and transmits the daily corrispettivi to the Agenzia delle Entrate. | No adapter, not a certified RT |
| United Arab Emirates | E-invoicing is arriving in phases. Businesses must appoint an FTA-Accredited Service Provider: by 30 October 2026 for revenue of AED 50m or more (live 1 January 2027), and by 31 March 2027 below that threshold (live 1 July 2027). Failure to appoint carries AED 5,000 per month. | No adapter, not an Accredited Service Provider |
| Saudi Arabia | ZATCA e-invoicing Phase 2 requires integration with the Fatoora platform — XML invoices, UUIDs, QR codes, digital signatures and clearance through ZATCA’s API. Businesses are brought in by wave; the waves announced through 2026 reach VAT-taxable revenue above SAR 375,000. | No adapter, no Fatoora integration |
| India | GST e-invoicing (IRN and QR via the IRP) applies from ₹5 crore aggregate turnover, and covers B2B supplies, exports and certain government supplies. A restaurant’s ordinary sales to diners are B2C, which this does not reach — but your turnover and any B2B supplies might. | No adapter, no IRP integration |
| United States | No federal fiscalisation or e-invoicing regime for restaurant sales. Sales-tax registration, collection and filing are set state by state, and remain yours. | No approval exists to hold |
Two of those rows say “no approval exists to hold” rather than “no adapter”, because the UK and the US have no fiscal-software approval regime for a vendor to be approved under. That is a fact about those countries, not a credential of ours.
Spain, Portugal, France, Germany, Italy and the Gulf mandates all fall here. The certified system stays where it is and keeps doing its job; Ontabee is where orders come in and where a complete, verifiable record of them lives. It does not discharge the requirement and does not pretend to. How the two sit together depends on your setup — ask us before you commit, and we will tell you if the answer is that we do not fit.
The UK and the US are here today. There is no approval to hold and no certified system to sit alongside, so the question becomes the simpler one: can you produce a complete, ordered record of your sales when somebody asks? That is exactly what the record chain is for, and in the UK it is worth knowing what HMRC is already penalising and currently proposing.
Because “add Spain” is not a checkbox, and pretending otherwise is how vendors end up making claims they cannot support.
Every regime defines its own record format, its own hashing and signing rules, and its own document numbering. They share an aim but almost no implementation. The platform is built so an adapter can be resolved per country — that scaffolding exists; what is behind it, today, is empty.
A certificate from an accredited body, a signing key, an accredited intermediary, or a live transmission channel to a tax authority — often several. Those are commercial and legal undertakings with ongoing obligations, not a sprint of engineering work.
Regimes move. Spain’s has been postponed twice; France withdrew publisher self-attestation in favour of accredited certification. An adapter is a standing commitment to track a country’s tax law, which is why we would rather ship none than ship one we let rot.
If your country is the thing standing between you and a decision, tell us which one. You will get a straight answer about where it sits — including, quite often, that we have no plans, which is more useful to you than a maybe.
No certification, but not nothing. Every order and payment movement is written to an append-only chain as it happens — one per location — each record hashed over all of its fields plus the hash of the record before it, so altering or removing one breaks every link after it. Each trading day is summarised into a Merkle root, and any period can be exported with a small program that recomputes every hash offline, on your accountant’s machine, with no account and no connection to us. Since 14 August 2026 each day’s root is also timestamped by an authority outside Ontabee, so a wholesale rebuild of the chain is detectable rather than merely difficult. Three limits we would rather you heard from us: that timestamp runs forward from that date and cannot vouch for a day that closed before it; the authority is a genuine independent third party but is not an eIDAS-qualified trust service provider; and a day is sealed once, at close, so changes made within the day before it sealed are outside what this catches.
No — nowhere, under no regime. We hold no fiscal-software certification, no tax-authority approval, no accreditation as a service provider, and no registration on any national list. We have also built no country-specific adapters: the platform writes one general-purpose, hash-chained record of every order and payment, and that is the whole of it. If a supplier tells you their ordering platform makes you compliant with a national invoicing regime, ask them which certificate, issued by which body, under which number.
Restaurants do, and the sales still have to be recorded and invoiced through whatever system your country requires. Ontabee is where the order is taken and where a complete, verifiable record of it lives; it is not the certified till or invoicing system, and does not replace one. How the two fit together depends on your country and your setup, which is a conversation to have with your accountant and with us before you commit, not afterwards.
No. Nothing here changes what you owe, what you must report, or when. It changes what you can produce when someone asks what came through your ordering channels — a record written at the time of sale, in sequence, that your accountant can verify without our help or our permission.
An append-only chain, one per location. Every order and every payment movement is written as it happens and hashed over all of its own fields plus the hash of the record before it, so altering or removing one record breaks every link after it. Each trading day is summarised into a Merkle root. You can export any period, and the export carries a small verification program that recomputes every hash and depends on nothing of ours — it runs offline, with no account. Since 14 August 2026 each day’s root is also timestamped by an authority outside Ontabee, which is what makes a wholesale rebuild of the chain detectable. Its limits, stated plainly: the timestamp only runs forward from that date, the authority is independent but not an eIDAS-qualified trust service provider, and a day is sealed once at close, so changes made inside that window before it sealed are not what this catches. None of which is certification — it is evidence, which is a different thing.
We are not going to promise a date on a public page, because a country adapter is not a feature toggle. Each one needs its own record format, and most need a certificate, a signing key, an accredited intermediary or a live transmission channel to a tax authority — and then it has to be kept current as the regime changes. If your country matters to your decision, tell us and we will give you a straight answer about where it sits, including if the answer is that we have no plans.
Every row was checked on 15 August 2026, and each is sourced. These regimes move — Spain's has been postponed twice — so we re-verify roughly every six months and date the page when we do. If you are making a decision on the strength of a row here, confirm it with your accountant rather than with us.
