1. Introduction

These Terms of Service (“Terms”) govern the provision of AI voice agent services by Xeminal Ltd T/A Agentus, a company registered in England and Wales (Company No. 14952973), registered office at 86-90 Paul Street, London, EC2A 4NE (“Agentus”, “we”, “us”). By signing up for our services or making payment, you (“Client”) agree to be bound by these Terms.

2. Service Description

Agentus designs, deploys, and maintains custom AI voice agents for professional services businesses. Services include:

• After-hours answering and call handling
• Integration with calendar systems and CRM platforms

Specific deliverables, timelines, and integrations will be confirmed in your engagement agreement prior to deployment.

3. Payment Terms

3.1 A one-time setup fee is payable in full prior to commencement of deployment.
3.2 Monthly subscription fees are payable in advance on a recurring basis.
3.3 Payment is by invoice, due within 7 days of issue. Accepted methods: bank transfer (BACS/SWIFT) and card payment.
3.4 All prices are quoted in USD unless otherwise agreed in writing.
3.5 Late payments may incur interest at 8% above the Bank of England base rate under the Late Payment of Commercial Debts (Interest) Act 1998.

4. Minimum Terms and Auto-Renewal

4.1 Flexible Start plans carry a minimum term of 6 months from the deployment date.
4.2 Preferred Rate plans carry a minimum term of 3 months from the deployment date.
4.3 After the minimum term expires, the subscription automatically renews monthly.
4.4 Either party may terminate after the minimum term by providing 30 days’ written notice to hello@agentus.online.

5. Cancellation Policy

5.1 Cancellation is not permitted during the minimum term. All fees due over the minimum term remain payable in full.
5.2 After the minimum term, written notice of at least 30 days is required to cancel. Notice must be sent to hello@agentus.online.
5.3 Setup fees are non-refundable under any circumstances.
5.4 Any outstanding overage charges will be invoiced upon cancellation.

6. Included Minutes, Overage, and Plan Upgrades

6.1 Included Minutes

Each plan includes a specified number of call minutes per calendar month: Starter (500 minutes), Growth (1,000 minutes), Premium (2,000 minutes). Unused minutes do not roll over to the following month.

6.2 Overage Rate

Usage above the included monthly allowance is billed at USD $1.40 per minute on all plans without exception. The service continues uninterrupted when the included allowance is exceeded — there is no automatic pause or suspension.

6.3 Overage Notifications

Agentus will send automated email alerts to the Client’s registered address at the following thresholds:

• 80% of included minutes used — advisory alert. No action required.
• 100% of included minutes used — overage alert with upgrade invitation. Overage billing begins from this point.

It is the Client’s responsibility to monitor usage and manage plan selection accordingly. Agentus is not liable for overage charges incurred where alerts were delivered to the registered email address.

6.4 Overage Billing

Overage charges are calculated at the end of each calendar month and invoiced within 5 business days of month-end. As a goodwill gesture, any overage minutes accrued within 48 hours of the 100% usage alert being sent will be waived if the Client upgrades their plan within that 48-hour window.

6.5 Plan Upgrades

A Client may upgrade to a higher tier at any time during their subscription by notifying Agentus in writing. On upgrade:

• The new plan’s monthly fee is charged on a prorated basis for the remaining days in the current billing month. The prorate is calculated as: (days remaining in month ÷ total days in month) × (new monthly fee − current monthly fee).
• The new plan’s full minute allowance is applied to the current month in full from the 1st of that month. Any overage already incurred before the upgrade remains payable at $1.40 per minute.
• From the next billing cycle onwards, the full new plan fee and full minute allowance apply.
• Upgrading does not extend or reset the original minimum term.
• No setup fee is charged on a plan upgrade — only the prorated fee difference.

6.6 Plan Downgrades

Downgrades to a lower tier are not permitted during the minimum term. After the minimum term, a downgrade request requires 30 days’ written notice and takes effect at the start of the next billing cycle.

6.7 Preferred Rate Overage

Preferred Rate plan overage is billed at USD $1.40 per minute, consistent with all other plans. This rate supersedes any prior engagement agreement that states a different figure.

7. Client Obligations

7.1 The Client must provide accurate business information required for agent configuration.
7.2 The Client is responsible for ensuring compliance with applicable laws governing automated calling, AI disclosure, and telephone marketing in their jurisdiction — including, without limitation, the US TCPA and applicable state laws.
7.3 Where required by law, the Client must obtain appropriate consent from call recipients before initiating outbound automated calls.
7.4 The Client must not use the service for any unlawful purpose.

8. Intellectual Property

8.1 All AI agent configurations, scripts, system prompts, and infrastructure created or deployed by Agentus remain the exclusive intellectual property of Xeminal Ltd.
8.2 The Client grants Agentus a limited licence to use their firm name, logo, and provided materials solely for the purpose of configuring and delivering the service.
8.3 Custom voice assets or branded materials created for the Client will be documented in the engagement agreement.

9. Limitation of Liability

9.1 Agentus shall not be liable for: system downtime caused by third-party infrastructure; call failures caused by network or carrier issues; or missed calls and bookings due to calendar integration failures beyond our reasonable control.
9.2 Our total aggregate liability shall not exceed the total monthly subscription fees paid in the three calendar months immediately preceding the event giving rise to the claim.
9.3 We shall not be liable for any indirect, consequential, or special loss — including loss of profit, loss of revenue, loss of cases or clients, or reputational damage.
9.4 Nothing in these Terms limits liability for death or personal injury caused by negligence, fraud, or any other liability that cannot be excluded by English law.

10. Confidentiality

Both parties agree to keep confidential any proprietary or sensitive information exchanged during the engagement and not to disclose it to third parties without prior written consent, except as required by law.

11. Governing Law and Jurisdiction

These Terms are governed by the laws of England and Wales. Any disputes shall be subject to the exclusive jurisdiction of the courts of England and Wales.

12. Changes to These Terms

We may update these Terms from time to time. We will provide at least 30 days’ notice of material changes by email or by posting notice on this page. Continued use of the service after the notice period constitutes acceptance of the updated Terms.
