Can I vibe code Taxually?

KEEP — THE UI ISN'T THE MOAT
What you pay Taxually for is legal compliance infrastructure, certified filings with EU member state tax offices, IOSS support, and liability handling. Calculating VAT amounts from transaction data is trivial to code, but interfacing with dozens of government portals—each with unique cryptographic signatures, XML schemas, and legal submission rules—is not. Building internal software to generate draft VAT reports takes a few days, but maintaining tax authority integrations and accepting legal audit liability makes a full custom build unfeasible without an internal legal and accounting operations team.

01
Why this verdict
While aggregating sales data to compute VAT liability is easy to code, Taxually's true value is regulated tax filing and legal compliance with government tax authorities across Europe. AI cannot act as a certified tax agent, hold power of attorney, or legally submit tax returns directly to foreign government portals.

The one-shot build prompt
Paste it into your agent of choice. Nothing else needed.
Build a Node.js/TypeScript backend service and React dashboard for internal EU/UK VAT sales aggregation and threshold tracking.
1. DATA MODEL:
- Store transactions with fields: order_id, created_at, billing_country, shipping_country, customer_type ('b2b' | 'b2c'), vat_number, line_items (sku, price, vat_rate, tax_amount), total_net, total_vat, total_gross, currency, exchange_rate_ecb.
- EU Tax Rules table mapping ISO country codes to standard/reduced VAT rates and historical effective dates.
- OSS Threshold table tracking annual cumulative cross-border EU B2C sales in EUR.
2. CORE FUNCTIONALITY:
- Ingest webhooks from Shopify/WooCommerce and map transaction data into unified order schema.
- Query the official EU VIES SOAP API to validate B2B buyer VAT numbers. If valid, set tax calculation to 0% (reverse charge mechanism) and store validation timestamp + request ID.
- Convert non-EUR order totals using official European Central Bank (ECB) daily exchange rate feeds.
- Calculate distance selling totals: aggregate annual B2C cross-border sales from EU warehouse to EU destinations. Raise alert status when exceeding €10,000 threshold.
- Export monthly aggregated OSS/IOSS audit report in standard CSV format grouped by destination country and VAT rate band.
3. INTEGRATION & ERROR HANDLING:
- Handle VIES API downtime gracefully: queue unverified VAT numbers for retry and flag orders for manual review.
- Prevent double counting on refunded or partially cancelled orders by processing refund webhooks and adjusting monthly net VAT totals.
4. OUT OF SCOPE:
- Direct government API submission or filing execution.
- Generating localized tax declaration XML/SAF-T files for local tax portals.
- Payment handling.$ each button prefixes agent-specific run instructions · build your own product, never copy proprietary code, trademarks or designs

FAQ
+Can I really replace Taxually with an AI-generated app?

An MVP takes roughly 1 week; matching the product properly is closer to Not possible (requires tax authority accreditation, fiscal representation, and certified API access).
+How long does it take to rebuild Taxually?
