How this service works
Retail Invoice total calculator: Calculate a line-item subtotal, user-supplied tax rate, and total. Tailored for retail workflows.
Output
Returns a computed breakdown including the line-item subtotal (sum of quantity × unit_price across all items), the tax amount derived from applying the provided percentage rate to the subtotal, and the final total (subtotal + tax). Useful for retail checkout flows, invoice generation, and order summaries.
Example use cases
Point-of-sale checkout total
“I need the total for a customer checkout: they're buying 4 items at $22.00 each and 1 item at $5.50, with a 7% sales tax applied — what's the subtotal and final total?”
Small business invoice generation
“Help me figure out the invoice total for a retail order: 10 units at $3.25 and 5 units at $12.00, with a 9.5% tax rate included.”
Quick tax-inclusive price check
“What would the total be if I ordered 2 items at $49.99 each and 3 items at $14.00 each, with 6% tax?”

Endpoint
POSThttps://market.datapackvibe.com/x402/invoice-total-retail?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a straightforward, retail-specific invoice computation that handles multiple line items with varying quantities and prices, plus a single configurable tax rate. Ideal for point-of-sale agents, e-commerce checkout bots, or invoice automation workflows where you need a reliable subtotal + tax + total breakdown without building the arithmetic yourself.
Side effects
- Missing or malformed items array returns a validation error
- Negative quantities or unit prices may produce incorrect results
- Tax rate provided as a decimal (e.g. 0.08) instead of percentage (e.g. 8) will result in wrong tax calculation
- Empty items array may return zero subtotal without error
- Network or payment failure (402) if USDC balance is insufficient
