Simso Fair Usage Policy

I. Scope and Background

This Simso Fair Usage Policy ("Policy") applies to the use of online products/SaaS solutions in addition to the General Terms and Conditions (GTC) to which you have agreed with your registration with or purchase of Simso.

This policy specifies certain maximum limits for the contractual use of online products/SaaS solutions by individual customers. These limits ensure, in particular, that the customer's own use, as well as that of other customers, is not impaired, and that the cloud resources required when using a SaaS solution are used appropriately and distributed evenly among all customers.

II. Maximum limits

Every customer is entitled to reasonable use of the online products/SaaS solutions. Reasonable use, in particular, requires compliance with the following maximum limits.

If you receive error messages or error codes when attempting to process or upload very large amounts of data via your online customer account, you are obliged to immediately stop the mass processing and notify us immediately.

III. Our Rights

Failure to comply with this policy constitutes a breach of contract regarding the use of the online products/SaaS solutions, which entitles us to assert our contractual and legal claims against you.

As of November 13, 2025

General Terms and Conditions (GTC)

These terms and conditions apply to all services and goods deliveries (online products/SaaS solutions) from Simso (hereinafter referred to as "versions" or "products"). The legal transaction is carried out by Simso Ltd in its own name.

1. Order; Conclusion of contract

1.1. The presentation of the versions/products in the online shop does not constitute a legally binding offer, but rather a non-binding online catalog. By clicking the "Buy"/"Order with obligation to pay" button, you submit a binding order. Confirmation of receipt follows immediately and does not yet constitute acceptance.

1.2. The software is up-to-date upon delivery. To ensure it remains up-to-date, the customer automatically participates in the subscription/update service according to the respective version/product description.

1.3. Our services are exclusively for businesses (B2B) and may only be used by them. By using our services, including trial subscriptions, the customer declares that they are a business.

2. Review period/test phase

If a trial period is specified (e.g., "Try it for 30 days free"), the customer has a trial period upon initial purchase. The test data will be automatically deleted no later than 13 months after the trial period ends if no subscription is formed.

3. Customer account; access

3.1. The use of online customer accounts requires mandatory registration. Registration for a legal entity may only be carried out by an authorized representative.

3.2. Customer access is password-protected. The customer is obligated to keep login credentials confidential. Simso employees are not authorized to request passwords by telephone or in writing. The customer is responsible for any misuse if two-factor authentication (2FA) was not activated at the time of the abusive activity.

4. Payment terms

4.1. We offer payment by credit card and direct debit (SEPA). Invoices are payable without deduction upon receipt. Invoices and payment reminders are generated automatically.

4.2. Delivery is made at the currently valid net price plus statutory VAT. The right to adjust prices annually is reserved, particularly for demonstrably increased operating costs.

4.3. The customer is not entitled to withhold payments unless they have a statutory right of retention arising from the same contractual relationship.

5. Termination

5.1. The subscription agreement can be terminated by the customer at any time with effect to the end of the current billing period (monthly or yearly).

5.2. Termination can be done directly in the customer account or by written form (email).

Special Terms for SaaS Solutions

1. Service Level

The SaaS solution is usually available 24 hours a day, 7 days a week. We aim for an availability of min. 99% on average over a calendar month, excluding planned maintenance work.

2. Support

We analyze and resolve documented errors. Error classes determine response times:

• Class 1 (Critical): Productive use impossible. Reaction time: 8 hours.
• Class 2 (Major): Core functionality ensured, but sub-module restricted. Reaction time: 2 working days.
• Class 3 (Minor): Other errors. Reaction time: 5 working days.

3. Customer Obligations

The customer may only use the services in accordance with applicable laws. It is prohibited to transfer data that violates legal regulations or contains viruses. The use of undocumented interfaces (not Public API) is prohibited.

AI Usage: The customer is responsible for all input into AI functions and the resulting output. AI output does not constitute legal advice. Input/Output is not used for training our public models.

Special Terms for Payroll

Lexware Office Payroll can be used as an extension. It enables payroll accounting using certified software modules. Communication with social security institutions and tax offices is handled electronically.

Upon termination of the Payroll module, the customer must specify a reason to ensure proper deregistration with social security institutions. Failure to do so requires manual deregistration by the customer.

Special Terms for Finance (Banking)

1. Payment Initiation (PIS) & Account Information (AIS)

Simso uses regulated third-party providers (or holds licenses where applicable) to provide Account Information Services (AIS) and Payment Initiation Services (PIS) under PSD2 regulations.

2. Consent

To use banking features, you must explicitly consent to Simso accessing your account data via your bank's secure API. You must renew this consent periodically (usually every 90 days) as per regulatory requirements.

3. Liability for Payments

You are responsible for checking recipient details before initiating payments. Simso transmits your instructions to your bank but does not hold funds. Once a payment is initiated and authorized by you (via 2FA/SCA), it cannot be revoked through Simso.
