cost_model:
  type: subscription_plus_overage
  description: Vatstack uses a base subscription fee per month with a defined number of included API calls (validations and supply records). Usage beyond the included quota is billed at a per-unit overage rate. The Developer plan is free with lower quotas. Quotes and rate lookups are unlimited on all plans.
unit_costs:
  - resource: validation
    description: A VAT ID validation request submitted to VIES or equivalent government service to verify a business VAT number.

    currency: USD
    unit: per validation (after monthly quota)

optimization:
  - name: Use Free Dummy Validations for Testing
    description: The Developer plan includes unlimited dummy validations using test VAT numbers. Always use dummy mode during development and integration testing to avoid consuming paid quota.
    savings_potential: high
  - name: Cache VAT Rates Locally
    description: VAT rates update at midnight local time. Cache rate responses for at least a few hours to reduce repeated lookups. The API itself caches quote history for 3 days.
    savings_potential: medium
  - name: Batch Validation Requests
    description: Use the Batches endpoint to group multiple VAT ID validations into a single operation rather than making individual validation requests, reducing overhead and managing quota consumption efficiently.
    savings_potential: medium
  - name: Right-size Your Plan
    description: Monitor monthly validation and supply record usage via the dashboard. Upgrading from Developer ($0) to Small Business ($15/month) reduces overage cost per validation from $0.09 to $0.03, breaking even at roughly 208 overage validations per month.
    savings_potential: high
  - name: Filter Validation Types
    description: Use the type parameter on validation requests to restrict checks to specific VAT number formats (eu_vat, gb_vat, etc.), avoiding unnecessary lookups against multiple government services when only one is needed.
    savings_potential: low

  - name: Dashboard Usage Tracking
    description: Monitor real-time validation and supply record consumption in the Vatstack dashboard at dashboard.vatstack.com to track quota usage and forecast overage costs.

  - name: Webhook Events
    description: Subscribe to webhook events for validation completion to trigger downstream workflows only when needed, rather than polling the API repeatedly.

break_even_analysis:
  - description: At what monthly validation volume does upgrading from Developer (free, $0.09/validation overage) to Small Business ($15/month, $0.03/validation overage) become cost-effective?
    calculation: $15 / ($0.09 - $0.03) = 250 overage validations
    threshold: 250 overage validations per month beyond the Developer plan included 100
  - description: At what monthly validation volume does upgrading from Small Business ($15/month, $0.03/validation overage after 500) to Enterprise ($150/month, $0.01/validation overage after 15000) become cost-effective?
    calculation: ($150 - $15) / ($0.03 - $0.01) = 6750 overage validations
    threshold: 6750 overage validations per month beyond the Small Business plan included 500
