Why?"},"content":{"rendered":"\n<p class=\"wp-block-paragraph\"><strong>\u201cI can find the Chamber of Commerce number on the purchase invoice, but Dexxter does not accept it as a VAT number. Why?&#8221;<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This question comes up regularly in the Dexxter community. The short answer: a Chamber of Commerce number is not the same as a VAT number.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In this article, we clearly explain the difference between a company number and a VAT number. We look at the situation in Belgium, the Netherlands, and France, so you know immediately which number you need when entering a document in Dexxter.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Belgium: one number, two functions \ud83e\udeaa<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In Belgium, the distinction is simple. <a href=\"https:\/\/dexxter.be\/en\/cbe-number-or-company-number-a-big-difference\/\">Your VAT number and your company number are the same<\/a>, except that the VAT number is preceded by \u201cBE&#8221;.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Company number<\/strong><br>When you register with the Crossroads Bank for Enterprises, you will receive a unique company number. This is the official identification number of your company.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>VAT number<\/strong><br>If you are subject to VAT, that same company number is activated as a VAT number. The number is preceded by the country code BE, for example BE0123.456.789.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You use this VAT number for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>invoicing<\/li>\n\n\n\n<li>VAT declarations<\/li>\n\n\n\n<li>intra-Community transactions<\/li>\n\n\n\n<li>VAT refunds<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Summary for Belgium<\/strong><br>You receive one number. If you are subject to VAT, that same number also becomes your VAT number, with BE in front of it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong><strong>The Netherlands: Chamber of Commerce number and VAT number<\/strong><\/strong> \ud83e\uddd0<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In the Netherlands, the Chamber of Commerce number and the VAT number are <strong>two separate numbers.<\/strong> So, unlike in Belgium, you cannot add \u201cNL\u201d to the Chamber of Commerce number to obtain the VAT number.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Chamber of Commerce number<\/strong> <strong>(KvK number)<\/strong><br>When you register with the Chamber of Commerce Trade Register, you will receive a Chamber of Commerce number. This number identifies your company for administrative purposes. It is often stated on invoices and official documents.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>VAT number<\/strong><br>You will receive your VAT number from the tax authorities when you become subject to VAT. This number is used exclusively for VAT purposes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>charging VAT<\/li>\n\n\n\n<li>submitting VAT declarations<\/li>\n\n\n\n<li>doing business with other businesses subject to VAT<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Chamber of Commerce number and the VAT number are therefore not interchangeable.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Summary for the Netherlands<\/strong><br>The Chamber of Commerce number (KvK number) is used for your registration. For everything related to VAT, you need a separate VAT number.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n<style>.kb-row-layout-id79235_5a7eca-8b >

crucial to know that our software specifically requires the VAT number to function correctly.<\/strong><\/strong><\/p>\n<\/div><\/div>\n\n<\/div><\/div>\n\n\n<h2 class=\"wp-block-heading\"><strong>France: SIREN, SIRET, and VAT number<\/strong> \ud83e\udee8<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">France has a somewhat more complex system with the <strong>SIREN number<\/strong>, <strong>SIRET number<\/strong>, and a separate <strong>VAT number<\/strong>. France therefore uses three numbers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>SIREN number<\/strong><br>This is the main identification number for your company.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The SIREN number identifies your company as a whole, regardless of the number of branches. It is comparable to the Belgian company number and the Dutch Chamber of Commerce number.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>SIRET number<\/strong><br>This number identifies a specific branch. It consists of the SIREN number supplemented with five additional digits. The SIRET number is used for local administration and communication with local authorities.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>VAT number<\/strong><br>For VAT purposes, you will receive a separate number from the tax authorities. It is mandatory for all companies subject to VAT and is used for collecting and paying VAT, submitting VAT declarations and intra-Community transactions. It starts with FR, followed by two digits and then the SIREN number.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Summary for France<\/strong><br>SIREN identifies your company, SIRET identifies your establishment, and the VAT number is used for tax obligations.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Which number do I need in Dexxter<\/strong>? \ud83e\udd14<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Dexxter always requires the official VAT number to process your purchase and sales documents correctly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Other numbers, such as the Belgian company number without BE, the Dutch Chamber of Commerce number, or the French SIREN or SIRET number, are not sufficient for VAT processing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">So if you only see a Chamber of Commerce number on a Dutch invoice, that is not the VAT number. You will need to look up or request the supplier&#8217;s correct VAT number.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Not sure if the number is correct? Always check if it starts with the right country code, like BE, NL, or FR. That&#8217;s usually the quickest way to see if you&#8217;re dealing with a VAT number.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>\u27a1\ufe0f In short: always enter the VAT number when sending invoices in Dexxter<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u201cI can find the Chamber of Commerce number on the purchase invoice, but Dexxter does not accept it as a VAT number.
