VAT on b2b sales even within an European country are usually not that important. You add VAT to things you sell (e.g. car repair services), you pay VAT on things you buy (e.g. car parts). If you collected more VAT on sales than you paid on purchases, you owe that to the tax department. It's a bit of book-keeping but doesn't affect your profits directly.
