SFTWARES LTD ("we", "us", "our") operates Invoice4You, available at invoice4you.app and as a mobile app on iOS and Android. By using Invoice4You you agree to these Terms and Conditions ("Terms"). If you do not agree, do not use the service.

Contact: support@invoice4you.app

2. Eligibility

You must be at least 18 years old and legally capable of entering into a binding contract to use Invoice4You. The service is intended for lawful business purposes only.

3. The App & Services

Invoice4You provides the following features:

• Invoice creation, management, and delivery by email
• Quote and proposal management
• Client and company management
• Expense tracking
• Automated payment reminders (email and push notification)
• HMRC Making Tax Digital (MTD) integration — connect your business to HMRC to meet your Making Tax Digital obligations for VAT and for Income Tax Self Assessment (ITSA): retrieve your obligations and submit VAT returns, ITSA quarterly updates, annual submissions and your final declaration directly to HMRC on your behalf

We reserve the right to modify, suspend, or discontinue any part of the service with reasonable notice. We will not be liable for any modification, suspension, or discontinuation of the service.

4. User Accounts

You are responsible for:

• Maintaining the confidentiality of your login credentials
• All activity that occurs under your account
• Reporting any suspected unauthorised access to support@invoice4you.app immediately

You must not share your account with others or create accounts on behalf of third parties without their consent.

5. HMRC Making Tax Digital (MTD)

5.1 What the MTD Feature Does

When you connect a company to HMRC within Invoice4You, you authorise us to:

• Retrieve your VAT obligations from HMRC on your behalf
• Calculate your VAT return figures from the invoices and expenses you have entered into Invoice4You
• Submit VAT returns to HMRC on your behalf using the data you confirm

For Income Tax Self Assessment (ITSA), when you connect a business you also authorise us to:

• Retrieve your Income Tax obligations (quarterly and final declaration) from HMRC on your behalf
• Calculate your quarterly and annual figures from the invoices and expenses you enter into Invoice4You
• Submit quarterly updates, annual submissions, and your final declaration to HMRC on your behalf, using the data you confirm

5.2 Your Responsibilities

You are solely responsible for:

• The accuracy of all invoice, expense, and financial data you enter into Invoice4You
• Reviewing the calculated VAT and Income Tax figures before submitting them to HMRC
• Ensuring your VAT return is submitted on time — Invoice4You displays your obligation due dates but cannot guarantee you will not miss a deadline
• Maintaining appropriate accounting records as required by HMRC and UK law
• Determining your correct VAT scheme (Standard, Flat Rate, Cash Accounting, etc.)

Invoice4You is not a tax adviser. The VAT and Income Tax figures displayed are calculated from the data you enter. They do not constitute tax advice, legal advice, or a guarantee of HMRC acceptance. For complex VAT or Income Tax queries, consult a qualified accountant or tax adviser.

5.3 VAT Return Submissions

• Once a VAT return has been submitted to HMRC, it cannot be undone through Invoice4You. You must contact HMRC directly to amend a submitted return.
• Invoice4You will show a confirmation screen with your HMRC reference number after each successful submission. Keep this for your records.
• Invoice4You will refuse to submit a duplicate return for the same period.

5.4 HMRC Tokens and Authorisation

• Your HMRC OAuth tokens are stored encrypted in our systems. You can revoke Invoice4You's access at any time by disconnecting within the app (Company → HMRC Connection → Disconnect) or by managing authorised applications in your HMRC online account.
• If you delete your Invoice4You account, all HMRC tokens are permanently deleted from our systems. This does not revoke Invoice4You's authorisation in HMRC's systems — you should also disconnect via your HMRC online account if you wish to fully revoke access.

5.5 Fraud Prevention Data

HMRC's API specification legally requires us to transmit device and connection information (fraud prevention headers) with every MTD API call. This includes your device ID, IP address, screen dimensions, and user agent. By using the MTD features, you consent to this data being transmitted to HMRC as required by law. See our Privacy Policy for full details.

5.6 HMRC Service Availability

Invoice4You's MTD features depend on HMRC's API being available. We are not responsible for delays, errors, or failures caused by HMRC system outages or maintenance. Check the HMRC API status page if you experience issues submitting returns.

5.7 Final Declaration (Income Tax)

Submitting a Final Declaration crystallises your Income Tax position for the tax year and is a legal declaration that the information submitted is correct and complete to the best of your knowledge. You must read and agree to the declaration statement before Invoice4You will submit it. As with a VAT return, once a Final Declaration is submitted it cannot be undone through Invoice4You — any amendment must be made via HMRC.

5.8 Tax Agents

If you use Invoice4You as a tax agent or bookkeeper acting on behalf of clients, you confirm that: (a) you are authorised by HMRC, via your Agent Services Account, to act for each client whose data you access or submit; (b) you have your client's agreement before submitting on their behalf; and (c) you are responsible for maintaining that authorisation and for the accuracy of any submission you make for a client. Where you act as a “supporting agent”, certain submissions (including the Final Declaration) may only be made by the client's main agent.

6. Subscriptions & Payments
