vendix-calculated-pricing

What problem does it solve?

This skill standardizes how calculated prices (base price plus taxes) are handled across the entire system, eliminating inconsistencies in pricing data and in UI displays.

Core Features & Use Cases

• Single Source of Truth: Persist only base_price and derive final prices at read time to avoid stale or conflicting totals.
• Tax Flexibility: Apply multiple tax rates dynamically to compute priceWithTax, supporting scenarios with VAT, municipal taxes, or regional rules.
• UI & API Consistency: Expose calculated totals for display while keeping mutations focused on the stored base_price.
• Use Case: When rendering invoices or product pages, the UI shows price_with_tax computed on the fly, remaining correct if tax rules change.

Quick Start

To apply this pattern, store base_price in your database, implement a priceWithTax getter on the frontend, and ensure APIs return price_with_tax for display but do not accept it in create/update payloads.
