Terms of Service

The Service is provided by Mykyta Ryzhov, a self-employed individual (autónomo) trading as "Invoister" ("we", "us"), NIF Z3913016P, C/ de Juan Ramón Jiménez, 17, Escalera 2, Piso 1G, Playa Muchavista, 03560 El Campello (Alicante), Spain. You can reach us at legal@invoister.app. See our Imprint for provider details.

You must be at least 18 years old and able to enter a binding contract to use the Service.

Invoister is an invoicing tool for freelancers and small businesses to create, manage and send invoices. It is intended for use by businesses and self-employed professionals in the course of their trade, not for personal or household purposes. If you use it on behalf of a business, you confirm you are authorised to accept these Terms for it.

The Service is currently in a closed beta. Features may change, be limited, or be withdrawn, and the Service may be unavailable or contain errors. We provide it during this period without any guarantee of stability or continuity.

You must provide accurate information and keep your login credentials secure. You are responsible for all activity that occurs under your account. Notify us promptly of any unauthorised use.

You may use the Service only for lawful purposes. You agree not to: issue fraudulent, fake or misleading invoices; use the Service for money laundering, tax evasion, or to invoice for illegal goods or services; send unsolicited or abusive email through the Service; infringe intellectual property or other rights; upload malware; scrape, overload, or attempt to gain unauthorised access to the Service; or resell the Service without our permission.

We may suspend or terminate your account, or stop email sending from it, if you breach this section.

You own the data you put into the Service, including your invoices, clients and business details. You grant us a limited licence to host, process and transmit that data solely to operate and provide the Service to you.

You are solely responsible for the content, accuracy, legality and tax-correctness of every invoice you create and send using the Service — including amounts, tax rates and modes, invoice numbering, dates, your business and bank details, and your clients’ details. Invoister is a tool: it does not verify, and does not guarantee, that an invoice complies with the invoicing, tax, VAT or accounting rules of any country.

The Service is not a certified or registered invoicing system under any national e-invoicing, invoice-reporting or invoice-verification scheme — for example Spain’s VERI*FACTU / Royal Decree 1007/2023, TicketBAI or SII, or mandatory structured e-invoicing in other countries. It is your responsibility to determine whether such a scheme applies to you and, where it does, to use a system that complies with it.

Keeping your records is your responsibility. The Service is not an archive or a record-keeping system for legal or tax purposes. You must keep your own copies of your invoices and records for as long as the law requires you to (you can export them at any time from Settings → Privacy, or download each invoice as a PDF). We do not keep your records for you after your account is deleted.

Emails you send through the Service are sent on your behalf. You are the sender: you choose the recipients and the content, and you are responsible for being entitled to contact them. Replies go to the email address of your business profile.

When you store or send personal data about your clients or their contacts — names, email and postal addresses, tax IDs, information submitted through your client onboarding links, and the content of your invoices — you are the data controller and we act as your data processor under Article 28 of the GDPR. You are responsible for having a lawful basis for that data and for informing the people concerned; this section is our data-processing agreement with you.

We process that data only to provide the Service to you, following your instructions as given through the Service, for as long as your account exists. We ensure that anyone who processes it is bound by confidentiality; apply the security measures described in our Privacy Policy; use only the subprocessors listed on our Subprocessors page, under written terms giving the same protection, and update that page before adding or replacing one (you may object by contacting us and, if we cannot resolve it, close your account); assist you, where reasonable, with requests from the people concerned and with your other GDPR obligations; notify you without undue delay after becoming aware of a personal-data breach affecting that data; and make available the information needed to show compliance with this section.

When your account is deleted we delete that data as described in our Privacy Policy, unless the law requires us to keep it. You can export it beforehand from Settings → Privacy.

Nothing in the Service — including templates, tax modes, suggested fields, help texts, or the AI assistant — constitutes legal, tax, accounting or financial advice. Consult a qualified professional for advice on your situation.

The Service may offer optional AI features. AI output can be inaccurate or incomplete. You must review and verify any AI output before relying on it, and we are not liable for actions you take based on it.

AI usage is subject to fair-use limits (currently 30 messages/month on the free plan and 500/month on Pro). We may rate-limit or suspend AI access for abuse or excessive use.

You may instead supply your own Anthropic API key in Settings. If you do, our monthly message limits no longer apply, Anthropic bills you directly at their rates, and we do not cap or monitor that spend — it is between you and Anthropic. Your key is stored encrypted, is never displayed again, and you can remove it at any time. Rate limits that protect the Service still apply.

Paid plans ("Pro") are sold and billed through our Merchant of Record, Lemon Squeezy, which acts as the seller of record for those transactions. Lemon Squeezy handles payment processing, billing, tax and VAT collection and remittance, and invoicing to you. Your purchase is also subject to Lemon Squeezy's terms.

Subscriptions renew automatically for the chosen billing period until cancelled. You can cancel at any time from your account settings; cancellation takes effect at the end of the current billing period. We will give at least 30 days’ notice of any price change, which applies from your next renewal after that notice; you can cancel before it does.

Payments are non-refundable. The free plan lets you try the Service before paying, so we do not refund subscription fees, including for partial billing periods, unused time or a plan you forgot to cancel. When you cancel, Pro stays active until the end of the period you have paid for and you are not charged again.

Where you are an EU/EEA consumer, you have a statutory 14-day right of withdrawal for digital services. Before checkout we ask you to expressly request that Pro starts immediately and to acknowledge that you lose that right once it does; you cannot upgrade without giving that confirmation.

This does not affect refunds that applicable law requires, or a charge made in error (for example a duplicate payment) — contact support@invoister.app and we will correct it through our Merchant of Record.

The free plan includes limited capacity (currently up to 3 clients, 15 invoices per client and 45 invoices in total). Pro plans have higher limits. We may adjust plan limits with reasonable notice.

The Service is provided on an "as is" and "as available" basis. We do not guarantee any particular uptime, and we may modify, suspend or discontinue any part of the Service, particularly during the beta period. If we discontinue the Service as a whole, we will give at least 30 days’ notice so you can export your data.

To the fullest extent permitted by law, the Service is provided without warranties of any kind, whether express or implied, including fitness for a particular purpose and non-infringement. This section does not affect mandatory statutory rights you have as a consumer.

To the fullest extent permitted by law, our total aggregate liability arising out of or relating to the Service is limited to the greater of (a) the fees you paid us in the 12 months before the event giving rise to the claim, or (b) €50. We are not liable for indirect, incidental, special or consequential damages, for loss of profits, revenue, goodwill or data, or for any tax, penalty, surcharge or interest imposed on you in connection with invoices created with the Service.

Nothing in these Terms limits or excludes our liability for: death or personal injury caused by our negligence; fraud or fraudulent misrepresentation; gross negligence or wilful misconduct; our statutory liability for the processing of personal data; or any liability that cannot be limited or excluded under applicable law, including mandatory Spanish and EU consumer-protection law.

To the extent permitted by law, you agree to indemnify and hold us harmless from third-party claims, losses and costs (including claims by your clients or by tax or data-protection authorities) arising out of your use of the Service, the invoices, emails and content you create or send, the personal data you process with it, or your breach of these Terms or of applicable law. This obligation applies in full to business users; for consumers it applies only to the extent permitted by mandatory law.

You may stop using the Service and delete your account at any time from Settings → Privacy. We may suspend or terminate your access if you breach these Terms or use the Service unlawfully. On termination, your data is handled as described in our Privacy Policy: it is permanently deleted 30 days after deletion, so export anything you need to keep before you delete your account.

We may update these Terms from time to time. We will notify you of material changes by email or in-app notice at least 30 days before they take effect, unless a change is required sooner by law. If you do not agree, you can cancel your subscription and delete your account before the change takes effect; continuing to use the Service after that date means you accept the updated Terms.

These Terms, together with the Privacy Policy and Lemon Squeezy’s terms for purchases, are the entire agreement between you and us about the Service. If any provision is found unenforceable, the rest remains in effect. Not enforcing a provision is not a waiver of it. We are not liable for delays or failures caused by events beyond our reasonable control. We may transfer these Terms to a company or other successor that takes over the Service, provided your rights are not reduced; you may not transfer them without our consent.

These Terms are governed by the laws of Spain, without prejudice to the mandatory consumer-protection rights you enjoy in your country of residence. If you are a consumer, you may also bring proceedings in the courts of your country of residence.
