Terms of service

These terms govern the relationship between the operator named above and everyone who creates an account in the service or works in one (the "user"). The service is for issuing and keeping sales documents, managing contacts, recording payments and connecting other systems through the API.

The terms have a general part (sections 1 to 10), which applies to everyone, a part for consumers (sections 11 to 17), a part for businesses (sections 18 to 23), the final provisions and two annexes: the instructions on withdrawal with the model form, and the acceptable use policy. A consumer is a person who orders the service outside their business; a business is anyone who orders it for their business.

An account belongs to whoever's billing details it carries. Whoever creates an account is its owner and invites other people with one of the roles owner, write and read, read only or accountant, may limit a person with write and read or read only to some sections, and may invite an accounting office, whose people get the accountant's access the office gives them. If the account turns the client portal on, its customer sees the documents the account issued to it at its own link.

The data processing agreement, under which the operator processes personal data on the user's behalf, the complaints procedure and the security policy are part of these terms. The privacy policy describes how the operator handles data about the users themselves.

Only a person aged 18 or older may create an account, accept an invitation to one and work in the service, and confirms it when creating the account and when accepting the invitation. The service is not meant for children; should the operator find that a person under 18 uses an account, it ends that person's access.

Users give true and complete details and keep them current. Whoever acts for a business declares that they are authorised to.

Users protect their sign-in and may turn on two-step sign-in. The owner of an account answers for the people they invite into it.

One person may hold several accounts, and one company ID may have several accounts.

The service is not provided to anyone whose seat or residence is in Russia, Belarus, the occupied territories of Ukraine, Iran, North Korea, Cuba or Syria; the service refuses a sign-up from these countries.

Whoever creates an account for a business declares that the business is not owned or controlled more than 50 % by a person subject to financial sanctions of the European Union or the Czech Republic, and will tell the operator without delay if that changes.

The free plan costs nothing. The account's owner orders paid plans, add-ons and packs of units on the billing page; nothing is charged without their order. The prices are in the price list on the service's website, and the order shows them again before payment.

The price list is on the page Pricing.

Payment is by payment card, saved for the plan's renewals, in advance: a purchase starts once it is paid. Only businesses in Vietnam and China pay by bank transfer, against a proforma after our check. Payments are processed by Stripe Payments Europe, Limited; to consumers outside the European Union the service is sold by Sold through Link, LLC as the merchant of record under Stripe Managed Payments.

The prepaid units of a pack (such as AI extractions of documents) are valid for the period the price list states, and one is used for each use.

Users answer for the content they enter and for the factual and legal correctness of the documents they issue, including VAT rates and regimes. The service calculates from the data users enter and by the statutory rounding rules; it does not replace tax or legal advice.

Users keep to the acceptable use policy of annex 2. The API has the request limits its documentation states.

An issued document never changes and is never deleted; it is corrected by a corrective document and withdrawn by a cancellation, as the service allows.

AI extraction: the service can read the details of an uploaded document with artificial intelligence, the Claude model of Anthropic. The result is only a proposal. AI can be wrong even when its result looks convincing, so the user checks every extracted detail before saving it and answers for it as for a detail entered by hand.

The operator aims to run the service without interruption and announces planned maintenance ahead where it can. Outages caused by third parties or force majeure do not breach these terms. This does not affect a consumer's rights for a defective service.

The data in an account belongs to the user. The owner and the accountant can download an export of all of the account's data as one file at any time, and the owner also after closing the account, for the period of section 7.

The account's data and its backups are stored in Microsoft Azure, region West Europe (the Netherlands); geo-redundant backups in North Europe (Ireland). A VAT payer keeping tax documents outside the Czech Republic tells its tax office where they are stored in advance (section 35(4) of the Czech VAT act, 235/2004 Coll.).

Every account is separated from the others in the database itself. The operator looks into an account only when its owner grants support access in the settings, for 7 days at most and read-only; every look is written to the account's audit log.

The database is backed up continuously, and the backups restore any moment of the last 7 days.

The owner can archive the account: an archived account can be read and exported, and nothing in it changes until the owner reactivates it.

The owner can close the account at any time. Every other member, the API credentials, webhooks and integrations end at once. For 30 more days the owners can request and download the export of all of the account's data; then all of the account's data, issued and received documents and their files included, is deleted for good.

Instead of closing, the owner can choose the archive as the alternative agreed retention period: the account stays read-only with export until the period section 35 of the Czech VAT act (235/2004 Coll.) sets for its latest issued document or expense ends, ten years from the end of the year it was issued or received, and then its data is deleted the same way. The user keeps the documents the law requires it to keep; whoever closes the account without the archive keeps them from the downloaded export.

The user can ask at any time to switch to another provider or to its own infrastructure. The notice period is 2 months at most, and the user may shorten it. A transition period of 30 days follows, in which the operator keeps providing the service and hands over all of the account's data in the export's machine-readable formats. Should the switch be technically impossible within 30 days, the operator says so with its reasons within 14 days of the request and extends the transition period to 7 months at most.

After the transition period the user has at least 30 more days to retrieve the data. Then the operator deletes all of the account's data, unless the owner chose the archive under section 7.

The operator charges nothing for switching, for exporting data or for ending the contract early, and imposes no penalty, now or after 12 January 2027.

The switching procedure, the register of the export's data structures and formats and the information on the infrastructure are on the page Your data and switching provider.

The user agrees that the operator issues and sends its tax documents for the service electronically (section 26(3) of the Czech VAT act, 235/2004 Coll.), to the billing e-mail of the order. The user confirms the consent in the order, and the operator records it with its time and version. The documents can also be downloaded on the billing page.

The operator stores the content users enter into the service and makes some of it available at a public link: the web invoice, the web quote and the client portal. The operator may restrict content that breaks the law or these terms. Its decision is one of these: no action; the account's public links disabled, so that its web invoices, web quotes and client portal are no longer available; the account suspended; or an earlier restriction lifted.

Anyone may report content they consider illegal through the public form for reporting content. A person rather than an automated system assesses the notice, and the operator tells the notifier its decision.

The form for reporting content is on the page Report content.

When the operator restricts an account, it sends the account's owners a statement of reasons (Article 17 of Regulation (EU) 2022/2065, the Digital Services Act): what it restricted, on what ground and on which facts, and the redress open to them. The account's owner and the notifier may complain against a decision by replying to the e-mail with the decision or through the contact page. They may also turn to a certified out-of-court dispute settlement body (Article 21 of the Digital Services Act) and to the courts.

The operator acts on orders of courts and authorities against illegal content and to provide information, and tells the user of them unless the order forbids it. Should it learn of a criminal offence threatening the life or safety of persons, it informs the law enforcement authorities (Article 18 of the Digital Services Act).

The plans, their functions, the add-ons and the packs of units are described in the price list. Prices for consumers are final, including all taxes; to consumers in the Czech Republic we show them in Czech crowns. Before payment the order shows what you buy, the total price, the price a month, whether and how the plan renews, how to end the renewal, the minimum term and the withdrawal period.

The payment methods are shown at the start of the order. A consumer pays by payment card in advance; the operator charges no fees beyond the price of the order.

A plan is paid for the period the consumer chooses, a month or a year, and the minimum term of the contract is that period. A plan renews automatically for the same period and is charged to the saved card until the consumer cancels it. Cancelling on the billing page stops the next renewal; the paid period runs to its end. Cancelling is possible at any time and as easy as ordering.

The operator may raise a plan's price only for a following period. It announces the increase in text form by e-mail at least 30 days ahead, and the consumer may cancel the plan free of charge before it applies; the paid period runs to its end at the old price.

A consumer may withdraw from the contract within 14 days of its conclusion, that is of the payment, without giving a reason. They withdraw with the "Withdraw from the contract" button on the billing page at the purchase, through the link in the order's e-mail, or by any clear statement, such as the model form of annex 1.

If the consumer expressly asks in the order that we start the service now, within the withdrawal period, and then withdraws, they pay the part of the price for the time the service was provided until the withdrawal. Without that request, we refund the whole amount paid.

For a pack of units, a consumer who withdraws pays at most for the units used after their request to start; we refund the unused units.

We refund the payment within 14 days of the withdrawal, the way the consumer paid.

Towards a consumer the operator neither excludes nor limits its liability for damage or for defects of the service; the limitation of liability in section 20 does not apply to consumers. Liability for defective products cannot be excluded or limited.

Throughout the contract the service has the features the price list and the help centre describe, and the operator supplies the updates needed to keep them. A consumer has the rights for a defective service under sections 2389a to 2389t of the Czech Civil Code; the operator does not alone decide whether the service is defective.

A consumer makes a complaint, and the operator handles it, under the complaints procedure, which is part of these terms. The operator settles a consumer's complaint within 30 days of its receipt at the latest.

The complaints procedure is on the page Complaints procedure.

A consumer may resolve a dispute under the contract out of court with the Czech Trade Inspection Authority (Česká obchodní inspekce), the body for out-of-court resolution of consumer disputes (https://adr.coi.cz). The Czech Trade Inspection Authority is also the authority supervising the duties towards consumers.

The operator may change these terms only for these reasons: a change of the law or a decision of an authority or a court, new or changed functions of the service, a change of the payment or other providers the service relies on, and the security of the service. It announces a change in text form by e-mail at least 30 days before it takes effect. The consumer may reject the change and end the contract free of charge before it applies; the operator refunds the part of the price paid for the rest of the period and the price of the unused prepaid units.

The operator may end a contract with a consumer without a serious reason only with at least 2 months' notice. It refunds the consumer the part of the price paid for the rest of the period and the price of the unused prepaid units.

The contract is governed by the law of the Czech Republic. A consumer whose habitual residence is in another state keeps the protection the mandatory provisions of the law of that state give them (Article 6(2) of Regulation (EC) No 593/2008, Rome I).

A consumer may sue the operator in the courts of the state where they live or in the Czech Republic; the operator may sue a consumer only in the courts of the state where the consumer lives (Article 18 of Regulation (EU) No 1215/2012, Brussels I bis).

The order has the steps what you buy, who pays, your consent, summary and review. Before payment every detail can be checked and changed, and an error corrected by going back to an earlier step. The contract is concluded by the payment; the operator confirms the order by e-mail without delay and sends these terms with it as a PDF.

The contract can be concluded in Czech or in English. The operator archives the concluded contract; the consumer finds their purchases on the billing page and the terms in the version of their purchase in the PDF the operator sent with the order confirmation.

A business established outside the Czech Republic accounts for any tax the purchase gives rise to in its state where the recipient accounts for it there (reverse charge or self-assessment).

Prices exclude any tax the customer must withhold. If it must withhold, the customer (a) withholds no more than the rate available under the applicable double tax treaty (we provide our Czech tax residence certificate on request), (b) increases the payment so that we receive the full invoiced amount as if nothing had been withheld, and (c) sends us the official receipt within 30 days; the customer bears any tax, interest or penalty arising from its failure to withhold or remit.

A business outside the European Union confirms the buyer's declaration in the order, which is stored with its version, time and IP address: "I declare that I act for a business registered for VAT/GST (or the local indirect tax) in [country] under [number], that I buy for that business, and that the business accounts for any tax due on this purchase in [country], including any tax it must withhold under the terms. The business is not majority-owned or controlled, directly or indirectly, from a country outside Anthropic's Supported Regions. I will tell Syonic solutions s.r.o. if this changes."

In the states where the business has no VAT/GST registration, the declaration reads: "I declare that I act for a business, that [country] levies no VAT/GST that the business would account for on this purchase; company number [number], that I buy for that business, and that the business accounts for any tax due on this purchase in [country], including any tax it must withhold under the terms. The business is not majority-owned or controlled, directly or indirectly, from a country outside Anthropic's Supported Regions. I will tell Syonic solutions s.r.o. if this changes."

The service's features are those the price list describes for the plan ordered and the help centre. The operator aims at uninterrupted availability, announces planned maintenance ahead and supplies the updates it chooses to release; unavailability under section 5 is not a defect.

A business reports a defect through the contact page. The operator removes it within a reasonable time; if it does not, the business may end the contract with immediate effect and the operator refunds the part of the price paid for the rest of the period. The business has no other rights for a defective service, subject to the liability of section 20.

Section 2389e of the Czech Civil Code does not apply between the operator and a business; sections 2389a to 2389f apply only so far as this section does not provide otherwise.

The operator is liable to a business in full for damage it causes intentionally or by gross negligence and for harm to a person's natural rights. Otherwise its liability is limited to what the business paid for the service in the last 12 months. The operator is not liable for lost profit or for damage arising from wrong data the user entered.

A plan renews automatically for the same period and is charged to the saved card until it is cancelled. Cancelling on the billing page stops the next renewal; the paid period runs to its end.

The operator announces a price increase for a following period by e-mail at least 30 days ahead; the business may cancel the plan before then.

The operator may change these terms for the reasons of section 15. It announces a change to the account's owners in text form by e-mail at least 30 days before it takes effect. The business may reject the change and end the contract without penalty before it applies; the operator refunds the part of the price paid for the rest of the period.

A business accepts the limitation of liability (section 20), the automatic renewal (section 21) and the changes to these terms (section 22) in the order by ticking each of them separately (section 1753 of the Czech Civil Code).

Sections 1799 and 1800 of the Czech Civil Code on contracts concluded by adhesion do not apply between the operator and a business (section 1801).

A contract with a business is governed by the law of the Czech Republic, and disputes under it are decided by the competent Czech courts.

The operator and the user communicate electronically.

If a provision is invalid, the others remain in force.

As a consumer you may withdraw from the contract within 14 days of its conclusion, that is of the payment, without giving a reason.

You withdraw with the withdraw button on the billing page or through the link in the order's e-mail. We refund the payment within 14 days of your withdrawal.

If you ask us to start the service now, within the withdrawal period, and then withdraw, you pay the part of the price for the time the service was provided until the withdrawal.
