It's a must-have for e-commerce and accounting software. ## Overview - **Category:** finance - **Price:** Free - **Endpoint:** https://edge.vinkius.com/vk_preview_JAUesYl5btRPCR1gaQnlrg9oeNtmgZie85rbEg4y/ai-agent-connect - **Tags:** vat, eu, tax, compliance, accounting, europe ## Description Managing taxes in Europe is a headache because every country has its own rules for what counts as a standard rate versus a reduced rate. If you're building a shop that sells to the whole EU, you can't just guess. This Connector takes that weight off your shoulders by giving your agent a direct line to accurate tax logic. Instead of you digging through government websites or maintaining a massive, outdated spreadsheet of percentages, your agent can just ask for the right number based on the product category and the destination country. It handles the math for B2C cross-border sales, where rules like the One Stop Shop (OSS) apply, and it knows how to spot a reverse charge for B2B deals. It basically acts as a live tax engine for your software. Since Vinkius hosts this, you can plug it into your existing workflow and let your agent handle the regulatory heavy lifting while you focus on building the actual product. It's about getting the right numbers on the invoice every single time without the manual double-checking. ## Tools ### check_vat_compliance Identify which regulatory path a transaction should follow, such as Reverse Charge or OSS. This helps ensure you stay on the right side of EU tax laws. ### compute_transaction_tax Calculate the exact tax amount and total invoice value for a sale. This tool handles the math for domestic and cross-border transactions. ### lookup_vat_rate Get the specific tax percentage for a country and product category. Use this to find standard, reduced, or essential good rates quickly. ## Prompt Examples **Prompt:** ``` What is the VAT rate for food in France? ``` **Response:** ``` The applicable VAT rate for 'Reduced Goods' in France (FR) is **5.5%**. Here is the breakdown: * **Category:** Reduced Goods * **Country:** France * **Rate:** 5.5% ``` **Prompt:** ``` Calculate the total for a €100 sale from Italy to Spain for a consumer. ``` **Response:** ``` For a B2C transaction from Italy (IT) to Spain (ES) with a net amount of **€100.00**, here is the breakdown: * **Applied Rate:** 21% * **Tax Amount:** €21.00 * **Total Invoice:** €121.00 *Note: This calculation follows the One Stop Shop (OSS) rule for cross-border B2C sales.* ``` **Prompt:** ``` Is a B2B sale from Germany to Ireland subject to reverse charge? ``` **Response:** ``` Yes, the transaction follows the **Reverse Charge** rule because it is a cross-border B2B sale between Germany and Ireland. ``` ## Capabilities ### Find specific tax percentages Get the correct VAT rate for any EU country based on product categories like standard or essential goods. ### Calculate total invoice amounts Generate precise tax amounts and total values for domestic and cross-border sales. ### Identify regulatory paths Determine if a transaction requires the Reverse Charge, Domestic VAT, or OSS rules. ### Handle B2C cross-border sales Automate tax calculations for consumer sales across different EU member states. ### Verify B2B compliance Check if business-to-business transactions correctly follow international tax requirements. ## Use Cases ### Automating multi-country storefront taxes A developer is building a shop that sells to the whole EU. They use lookup_vat_rate to fetch the correct percentage based on the user's location and what they're buying. ### Auditing international B2B sales A finance team needs to know if a sale from Germany to Ireland was a reverse charge. The agent runs check_vat_compliance on the transaction history to flag the correct rule. ### Calculating real-time B2C totals An e-commerce owner wants to know the total price for a customer in Spain buying from Italy. The agent uses compute_transaction_tax to calculate the exact € amount including the 21% VAT under OSS. ### Identifying reduced rates for food A startup is launching a food delivery app in France. They use lookup_vat_rate to identify the 5.5% rate for 'Reduced Goods' instantly. ## Benefits - Stop manually updating tax tables because lookup_vat_rate handles all 27 EU member states automatically. - Eliminate calculation errors in cross-border invoices by using compute_transaction_tax for every sale. - Reduce compliance risks by using check_vat_compliance to verify if a transaction needs the OSS rule. - Speed up the development of accounting software by offloading complex tax logic to your AI agent. - Handle diverse product categories like essential goods or reduced items without hardcoding different rates. ## How It Works The bottom line is you get accurate, real-time EU tax calculations without having to manually research every country's rules. 1.
