1. Introduction
These Terms and Conditions (“Terms”) govern your use of the Arvello platform (the “Service”), operated by Namasgo OÜ, a private limited company registered in Estonia (registry code: 16747054), with its registered address at Harku Tee 34, Rannamõisa, 76906 (“Arvello,” “we,” “us,” “our”).
By creating an account or using the Service, you agree to these Terms. If you are using the Service on behalf of a company or other legal entity, you represent that you have the authority to bind that entity to these Terms.
Please read these Terms carefully. If you do not agree, do not use the Service.
2. Definitions
“Account” means your registered Arvello user account.
“Business Data” means all financial, accounting, and business information you enter into, import into, or generate through the Service, including invoices, expenses, bank transactions, payroll data, tax filings, and annual reports.
“Subscription” means your paid plan giving you access to the Service, as selected during registration or subsequently changed.
“User” or “you” means the individual or legal entity that has registered for an Account.
3. About the Service
3.1 What Arvello is
Arvello is self-service accounting software designed for Estonian OÜ companies. The Service provides tools for invoicing, expense tracking, bank reconciliation, payroll calculations, VAT reporting, annual report generation, and related features.
3.2 What Arvello is not
Arvello is software, not an accounting firm. The Service does not provide accounting, tax, legal, or financial advice of any kind. Arvello does not employ or contract accountants or tax advisors to review your data or outputs.
You are solely responsible for:
- The accuracy and completeness of all data you enter into the Service
- Reviewing all outputs (reports, calculations, filings) before relying on them or submitting them to authorities
- Ensuring your use of the Service complies with all applicable laws, including Estonian accounting, tax, and employment laws
- Filing obligations, deadlines, and regulatory compliance for your company
- Seeking professional accounting or legal advice when your situation requires it
We strongly recommend that you consult with a qualified accountant or tax advisor for complex situations, including (but not limited to) multi-entity structures, cross-border transactions, transfer pricing, and matters involving significant financial risk.
4. Account registration
4.1 Eligibility
The Service is designed for use by Estonian OÜ companies and their authorised representatives. You must be at least 18 years old and legally capable of entering into contracts to create an Account.
4.2 Account security
You are responsible for maintaining the confidentiality of your login credentials and for all activity under your Account. You must notify us immediately at info@arvello.ee if you suspect unauthorised access.
4.3 Accurate information
You agree to provide accurate, current, and complete information during registration and to keep it updated. We may suspend or terminate your Account if we reasonably believe the information you provided is inaccurate or fraudulent.
5. Subscriptions and payments
5.1 Plans and pricing
The Service is offered on a subscription basis with different plan tiers. Current pricing is available at https://arvello.ee/pricing. Prices are stated in euros (EUR) and exclude VAT unless stated otherwise.
5.2 Billing
Subscriptions are billed in advance on a monthly or annual basis, depending on the plan you select. Payment is processed through Stripe. By subscribing, you authorise us to charge your payment method on each billing date.
5.3 Price changes
We may change subscription prices with at least 30 days' advance notice by email. Price changes take effect at the start of your next billing period after the notice period. If you do not agree with a price change, you may cancel your subscription before the new price applies.
5.4 Taxes
You are responsible for any applicable taxes on your subscription (including Estonian or local VAT). If we are required to collect VAT, it will be added to your invoice.
5.5 Failed payments
If a payment fails, we will attempt to charge your payment method again and notify you. If payment remains unsuccessful after 14 days, we may suspend your access to the Service until payment is resolved. Your data will be preserved during suspension.
6. Free trial
If we offer a free trial, you may use the Service without payment for the specified trial period. At the end of the trial, your access will convert to a paid subscription unless you cancel before the trial ends. We will notify you before any charge is applied.

You acknowledge that Arvello is a tool to assist you with accounting tasks. The responsibility for ensuring the accuracy of your financial records, the correctness of your tax filings, and compliance with Estonian law remains with you at all times. You agree that it is your responsibility to verify all outputs generated by the Service, including calculations, reports, and filings, before relying on them.
14. Indemnification
You agree to indemnify and hold Namasgo OÜ harmless from any claims, damages, losses, or expenses (including reasonable legal fees) arising out of your violation of these Terms, your misuse of the Service, the inaccuracy of Business Data you provided, filings or submissions you made using outputs from the Service without adequate review, or your violation of any applicable law.
15. Disclaimer of warranties
The Service is provided on an “as is” and “as available” basis. To the maximum extent permitted by law, we disclaim all warranties, whether express, implied, or statutory, including (but not limited to) implied warranties of merchantability, fitness for a particular purpose, and non-infringement.
Without limiting the foregoing, we do not warrant that the Service will be uninterrupted, error-free, or free of viruses or other harmful components; that calculations, reports, or other outputs will be accurate, complete, or current; that the Service will meet all of your specific requirements; or that any defects will be corrected.
16. Suspension and termination
16.1 Termination by you
You may cancel your subscription at any time through your account settings or by emailing info@arvello.ee. Cancellation takes effect at the end of your current billing period. You will retain access to the Service until then.
16.2 Termination by us
We may suspend or terminate your Account if you breach these Terms and fail to remedy the breach within 14 days of our notice, your payment is overdue for more than 30 days, you use the Service for illegal purposes, or continued provision of the Service to you would violate applicable law.
We will provide reasonable notice before termination unless immediate action is required to prevent harm or comply with law.
16.3 Effect of termination
Upon termination, your right to use the Service ends, you may export your Business Data for 30 days following termination (unless terminated for illegal activity), and after the 30-day export period, your data will be handled as described in Section 7.5 and our Privacy Policy.
Sections that by their nature should survive termination will continue to apply, including Sections 7 (Your data), 11 (Intellectual property), 13 (Limitation of liability), 14 (Indemnification), 15 (Disclaimer), and 18 (Governing law).
17. Changes to these Terms
We may update these Terms from time to time. When we make material changes, we will notify you by email at least 30 days before the changes take effect and post the updated Terms on our website with a clear “last updated” date.

20.3 No waiver
Our failure to enforce any right or provision of these Terms does not constitute a waiver of that right or provision.
