Welcome to Filssi. These Terms and Conditions ("Terms") govern your access to and use of the Filssi platform, including all associated services, features, and applications (collectively, the "Service").
Filssi is a software platform owned and operated by Creator Business OS Ltd, a company registered in England and Wales under company number 17168418, with registered office at [Registered Office Address] ("Creator Business OS Ltd", "Company", "we", "us", or "our"). Further information about Creator Business OS Ltd is available at www.creatorbusinessos.com.
By creating an account, accessing, or using the Service, you ("Customer", "you", or "your") acknowledge that you have read, understood, and agree to be bound by these Terms and our Privacy Policy. If you are accepting these Terms on behalf of an organisation or legal entity, you represent and warrant that you have the authority to bind that entity to these Terms, in which case "you" refers to that entity.
If you do not agree to these Terms, you must not access or use the Service.
These Terms constitute a legally binding agreement between you and Creator Business OS Ltd. We reserve the right to modify these Terms at any time. Material changes will be communicated in accordance with Section 19.
For the purposes of these Terms, the following definitions apply:
Filssi is a business software platform that provides tools for accounting, payroll, invoicing, CRM, reporting, and business administration. It is designed to support and streamline internal business operations.
Important: Creator Business OS Ltd does not provide regulated accounting services, tax advice, legal advice, payroll bureau services, or financial advice of any kind. The Service is a software tool. Nothing within the Service constitutes professional advice, and it should not be relied upon as such.
Customers remain solely responsible for obtaining appropriate professional advice — including from qualified accountants, tax advisers, payroll professionals, and legal counsel — where required for their specific circumstances. The Company accepts no liability for any decisions made by Customers or their advisers based on output generated by the Service.
To access the Service, you must create an account by providing accurate, current, and complete information. You are responsible for maintaining the accuracy of your account information and for updating it promptly if it changes.
You are responsible for safeguarding the password and credentials used to access your account. You must not share your login credentials with any third party. You must notify us immediately if you become aware of any unauthorised access to or use of your account at support@filssi.com.
You are responsible for all activities that occur under your account. The Company shall not be liable for any loss or damage arising from your failure to maintain the security of your account credentials.
Account owners may invite additional Users to their organisation within the Service. The account owner is responsible for managing team member access, permissions, and ensuring that all Users comply with these Terms. Additional Users may incur per-user fees as detailed in Section 5.
You must be at least 18 years of age to create an account and use the Service. By creating an account, you confirm that you meet this requirement.
The Service is offered under the following core subscription plans. Prices are in British Pounds Sterling (GBP) and are exclusive of applicable VAT or taxes, which will be added where required by law:
| Plan | Base Fee (Monthly) | Per Admin/Staff User (Monthly) | Annual Option |
|---|---|---|---|
| Starter | £25.00/month | £8.00/user/month | 10 months pricing (2 months free) |
| Growth | £49.00/month | £10.00/user/month | 10 months pricing (2 months free) |
| Pro | £89.00/month | £12.00/user/month | 10 months pricing (2 months free) |
The Employee Self-Service Portal ("Staff Portal") allows employees to submit and manage expense claims through a dedicated login, without access to company accounts, financial reports, or sensitive business data.
The Client Portal allows Customers to share invoices securely with their clients online. Clients can view outstanding and paid invoices and, where enabled, make payments directly through the portal.
All companies on the Service are automatically assigned a unique inbound email address (in the format {company-identifier}@ap.filssi.com) for the Accounts Payable (AP) Email Capture feature. This allows suppliers and vendors to send invoices directly to that address, where they are automatically processed by OCR, parsed, and converted into draft AP bills within the platform.
The Service includes an automated document scanning (OCR) capability for extracting data from invoices, receipts, and other financial documents. OCR usage is subject to the following monthly limits per subscription plan:
| Plan | OCR Scans per Month |
|---|---|
| Starter | 50 scans/month |
| Growth | 500 scans/month |
| Pro | Unlimited |
OCR results are provided as-is. The Customer is responsible for verifying all extracted data before use.

The full and authoritative list of features available on each plan is as published on the Filssi website at the time of subscription. Creator Business OS Ltd reserves the right to add features to or remove features from any plan with reasonable prior notice.
All subscriptions renew automatically at the end of each billing cycle (monthly or annual) unless cancelled before the renewal date. Payment is taken at the start of each billing cycle in advance. By subscribing, you authorise Creator Business OS Ltd to charge your designated payment method for all applicable fees on each renewal date.
All payments are processed through Stripe, our third-party payment processor. VAT or other applicable taxes will be added where legally required.
Each plan includes a base fee plus a per-user fee for each active User in your workspace. Per-user fees are calculated at the start of each billing cycle based on the number of active Users at that time.
Upgrades: You may upgrade your subscription at any time. The upgrade takes effect immediately.
Downgrades: Downgrades apply from the start of the next billing cycle. No refund or credit is issued for the remainder of the current billing period.
You may cancel your subscription at any time through your account settings or by contacting support@filssi.com. Cancellation stops future automatic renewals only. You will retain access to the Service until the end of the current paid billing period. After this, your account will be deactivated and your data retained for 30 days before permanent deletion.
We may update our pricing from time to time. Where changes affect your existing subscription, we will provide reasonable prior notice — ordinarily at least 30 days — before the new price takes effect at your next renewal.
If a payment fails, we will notify you and attempt to retry the charge. Persistent failure to pay may result in suspension of your account after reasonable notice. Access may be restored upon payment of all outstanding amounts.
Subscription fees are non-refundable once a billing cycle has commenced, except where required by applicable law or expressly agreed in writing by Creator Business OS Ltd.

When you use the Service to process Personal Data of your clients, customers, or employees, you act as the Data Controller and Creator Business OS Ltd acts as your Data Processor. We process Personal Data only on your documented instructions and in accordance with applicable data protection law.
By accepting these Terms, you agree to our Data Processing Agreement (DPA), which is incorporated by reference. The DPA sets out the scope, nature, and purpose of data processing, the types of Personal Data processed, and the obligations and rights of both parties. A copy of the DPA is available upon request to support@filssi.com.
We engage the following sub-processors to assist in delivering the Service. Each sub-processor is bound by contractual obligations to protect your data:
We may update or replace sub-processors from time to time. Where legally required, we will provide notice of material changes.
In the event of a personal data breach, we will notify you without undue delay and, where feasible, within 72 hours of becoming aware of the breach, in accordance with Article 33 of the UK GDPR.
You retain full ownership of all data and Content you upload, create, or store within the Service. Creator Business OS Ltd does not claim any ownership rights over your data. We will not access, use, or disclose your data except as necessary to provide the Service, comply with legal obligations, or as otherwise described in these Terms and our Privacy Policy.

After this period, your data will be permanently and irreversibly deleted from our systems, except where retention is required by law.
We retain your data for as long as your account is active and for 30 days following account cancellation or termination. Certain data may be retained for longer periods where required by law — for example, financial records may be retained for up to 7 years for HMRC compliance purposes.
We aim to maintain a reliable and highly available Service. Any uptime figures or percentages we publish are targets only and are not contractual guarantees unless expressly stated in a separate written Service Level Agreement (SLA) executed with your organisation.
Scheduled Maintenance: We will provide reasonable advance notice of planned maintenance. Where possible, maintenance will be performed during off-peak hours.
Unscheduled Downtime: In the event of unscheduled downtime, we will use commercially reasonable efforts to restore the Service as quickly as possible.
Temporary outages, maintenance windows, service degradation, third-party failures, internet issues, or platform interruptions do not entitle the Customer to refunds, service credits, damages, or compensation unless expressly agreed in a separate written Service Level Agreement.
The Service is provided on an "as is" and "as available" basis. We do not guarantee that the Service will be uninterrupted, error-free, or free from security vulnerabilities at all times.
From time to time, Filssi may offer beta, preview, or early-access features. These features are provided for evaluation purposes and may be incomplete, subject to change, or withdrawn without notice.
Filssi may integrate with or depend upon third-party services including hosting providers, payment processors, email delivery systems, OCR tools, open banking feeds, or government systems such as HMRC's Making Tax Digital (MTD) APIs.
Creator Business OS Ltd is not liable for delays, outages, rejected submissions, failed synchronisations, data errors, or service interruptions caused by third-party systems or government platforms outside our reasonable control.
