VAT calculations & legislative reasoning on complex transactions
For in-house VAT and finance exec’s – or advisors in practice – understanding the VAT obligations on complex transactions is fiercely complex and time-consuming.
Who holds the liabilities? How much VAT is due and where? Should you be VAT registered? What legislative articles are the answers based on? What detail to include to ensure compliant sales and purchase VAT invoices (download a compliant invoice to share)? Which boxes and countries to report transactions in VAT returns?

Advisor covers the national legislation for a huge array of business: B2C; B2B; goods; general & digital services
VAT Advisor is a simple-to-use but hugely powerful online tool that allows you to input some basic transaction details – goods, values, shipping, transaction type, shipping details etc – to produce a clear VAT liability position for the seller and buyer. Outputs include legal citations (local laws and EU VAT Directive), and which boxes to fill on local VAT returns and supplementary filings. Since VAT Advisor is one the same single platform as our VAT Filer product, you can ‘commit’ it to be included in your approved transaction database for automatic inclusion in the right boxes in the right countries’ VAT returns. No further integrations required!

Create VAT compliant PDF invoices for your colleagues, customers or suppliers which can be shared within the application to discuss and resolve.
If you want to share the correct VAT treatment with colleagues or outside counterparts, you can ‘click’ to create a compliant PDF invoice. You can share this with them within the VAT Calc application (just input their email for them to gain access). Or download the invoice and email in the regular way.
