I’ve been working on tax configuration for an EU-based company, and while setting up VAT rules, I initially didn’t input the VAT Number and EORI Number As you know, understanding VAT and EORI numbers in Netsuite. • VAT number(Value Added Tax) This Identifies a business for tax purposes within the EU. • EORI number This is used for import/export declarations in the EU and UK. Shortly, without these fields properly configured, even well-built workflows and tax codes can fail in real operations.
