Invoice Pro

Terms of Service

Last updated: 27 August 2026

These Terms of Service (“Terms”) are a legally binding agreement between you and Arnold Labs (“Arnold Labs”, “we”, “us”, or “our”) for your use of the Invoice Pro mobile application and related services (the “Service”).

By creating an account, signing in, or using Invoice Pro, you agree to these Terms. If you do not agree, do not use the Service.

1. Who we are

Invoice Pro is a product of Arnold Labs. Contact: arnoldlabs.dev@gmail.com

2. The Service

Invoice Pro is software that helps a business owner create invoices and quotations, record payments, track expenses, and share documents. Invoice Pro is not a bank, payment processor, or money transmitter; not an accountant, lawyer, or tax authority; and not a substitute for professional legal, tax, or accounting advice.

You remain solely responsible for the accuracy of amounts, taxes, client details, and documents you issue, and for complying with laws in your country.

3. Eligibility and account

You must be able to form a binding contract. You must provide accurate registration information and keep your password confidential. You are responsible for activity under your account. Notify us promptly at arnoldlabs.dev@gmail.com if you believe your account is compromised.

One Invoice Pro account is intended for one business owner. You may not share your login to evade subscription limits once paid plans are in force.

4. Access

Invoice Pro provides Pro access as shown in the app. One Pro subscription unlocks the same account on web and Android. Paid subscriptions may be billed through Google Play (Android) or, on the web, through Paddle (default) or Paystack (local methods such as M-Pesa). Prices are displayed in Subscription before you pay.

5. Subscriptions

The Pro plan is offered as a subscription (monthly USD 10.00 or yearly USD 100.00, or the prices then shown in the app).

The app will not write your plan itself. Entitlement is recorded on our servers.

6. Your content

You retain ownership of your business data (company profile, clients, invoices, quotations, payments, expenses, logos, signatures, and similar content) (“Your Content”). You grant Arnold Labs a limited licence to host, process, and display Your Content solely to operate the Service for you.

You represent that you have the right to upload Your Content and that it does not infringe others’ rights or contain unlawful material.

7. Acceptable use

You agree not to use the Service for fraud, money laundering, or illegal invoicing; attempt to access another user’s data; reverse engineer, disrupt, or overload the Service; scrape the Service except as allowed by a documented API we publish; or upload malware or content that is defamatory, hateful, or exploitative of minors. We may suspend or terminate accounts that violate these Terms.

8. Payments you record and public links

Recording a payment in Invoice Pro only updates your records inside the app. It does not move money from your client to you. Methods such as M-Pesa, bank transfer, card, or cash happen between you and your client outside Invoice Pro.

A view-only public link shows a snapshot of an invoice or quotation (including a PDF) to anyone who has the unguessable URL. It does not collect payment for that invoice. When you email or message a document, you use your own Gmail, WhatsApp, or other accounts.

9. Intellectual property

Invoice Pro, its name, logos, templates, and software are owned by Arnold Labs or its licensors. These Terms do not sell you those rights. You may not copy the app or templates for a competing product.

10. Privacy

Our Privacy Policy explains how we process personal data. By using the Service you also acknowledge that policy.

11. Disclaimers

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE”. TO THE MAXIMUM EXTENT PERMITTED BY LAW, ARNOLD LABS DISCLAIMS WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. We do not warrant that the Service will be uninterrupted, error-free, or that documents will meet a third party’s requirements.

12. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, ARNOLD LABS SHALL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, DATA, OR BUSINESS. OUR TOTAL LIABILITY FOR ANY CLAIM RELATING TO THE SERVICE SHALL NOT EXCEED THE GREATER OF (A) THE AMOUNTS YOU PAID US FOR THE SERVICE IN THE 12 MONTHS BEFORE THE CLAIM, OR (B) USD 50.

Some countries do not allow certain limitations. In those places, our liability is limited to the maximum extent permitted.

13. Indemnity

You will defend and indemnify Arnold Labs against claims arising from Your Content, your invoices, your tax treatment, or your breach of these Terms.

14. Termination

You may stop using the Service and delete your account in Settings. We may suspend or terminate access if you breach these Terms or if we discontinue the Service, with reasonable notice where practicable.

15. Changes

We may update these Terms. We will change the “Last updated” date and may notify you in the app. Continued use after the update means you accept the new Terms. If you do not agree, stop using the Service and delete your account.
