If your business is VAT-registered — whether you're in the UK, UAE, Saudi Arabia, or anywhere else in Europe or the Middle East — every invoice you issue needs to meet specific VAT requirements. Miss any of them and your customer can't reclaim the VAT, which creates friction, disputes, and a poor impression of your business.

The good news: creating a fully VAT-compliant invoice from your phone takes about 60 seconds with the right app.

What a VAT Invoice Must Include

VAT invoice requirements vary slightly by country, but the core elements are consistent across the UK (HMRC), UAE (FTA), Saudi Arabia (ZATCA), and EU member states:

  • Your business name, address, and VAT registration number
  • Customer's name and address (and their VAT number for B2B invoices)
  • A unique sequential invoice number
  • Invoice date and tax point date
  • Description of goods or services supplied
  • Net amount (excluding VAT), VAT rate, VAT amount, and gross total
  • For the UAE/KSA — invoices must also be available in Arabic

Getting all of this right manually in a Word template is time-consuming and easy to get wrong. An invoice app handles it automatically every time. If you're also dealing with GST in countries like India, Australia, or New Zealand, see our guide on how to send a GST invoice from your phone.

How Invoice & Business Finance Handles VAT Invoicing

Invoice & Business Finance is a free iPhone and Android app that generates fully VAT-compliant invoices with all required fields, automatic tax calculations, and professional PDF output — ready to share instantly.

Set up your VAT rate once
Enter your VAT rate in settings — 20% for the UK, 5% for the UAE and Saudi Arabia, or whichever rate applies to your business. The app applies it automatically to every invoice going forward.

Your VAT number appears on every invoice
Enter your VAT registration number in your business profile and it appears automatically on every invoice generated — no manual entry each time, no risk of forgetting it.

Net, VAT, and gross clearly itemised
The invoice automatically shows the net amount, the VAT amount, and the gross total — clearly separated exactly as required for a valid VAT invoice.

Quote First, Invoice Later
For businesses that provide estimates before confirming a sale — very common in construction, trade services, and professional services — the Quotations feature lets you send a professional quote first, then convert it to a VAT-compliant invoice in one tap when the client confirms. No re-entering details, no duplicate work, everything organised per business.

Multi-Rate VAT Support

Some businesses deal with multiple VAT rates — for example in the UK where most goods are standard-rated at 20% but some are reduced-rated at 5% or zero-rated. The app supports different tax rates per line item within the same invoice, so mixed-rate invoices are handled cleanly.

VAT Invoicing for the UAE and Saudi Arabia

For businesses operating in the Gulf, the app's Arabic language support means invoices can be generated and shared in Arabic — meeting the bilingual requirements of UAE and KSA VAT regulations. The 5% VAT rate is configurable in settings, and the invoice format meets FTA and ZATCA requirements.

Track Your VAT Across Reporting Periods

The expense tracking and P&L reports connect your VAT-collected data to your overall financial picture. While the app doesn't file VAT returns directly, having clean categorised records of VAT charged across each period makes the filing process significantly faster — whether you're filing with HMRC, the FTA, or ZATCA.

Budget and Cash Flow for VAT-Registered Businesses

One often-overlooked aspect of VAT registration is that VAT collected isn't your money — it needs to be remitted to the tax authority on a quarterly or monthly basis. The Budget feature helps you plan for this by setting aside the right amount each month, while the cash flow forecast ensures VAT payment dates don't catch you short.
