How this service works
Calculate subtotal, per-line tax, discount and deposit from supplied invoice line items. Per-line tax percent (not a single flat rate), discount applied to the pre-tax subtotal, deposit as a percent-of-total or fixed amount clamped to the total. Pure arithmetic; does not create, store or send an invoice.
Output
Returns a computed breakdown including subtotal, per-line tax amounts, total tax, post-discount subtotal, deposit amount, and final invoice total — all as numeric values derived from the supplied line items and parameters. No data is stored or transmitted.
Example use cases
Contractor quote with mixed tax rates
“I need to calculate the total for a plumbing job invoice — I have 3 labor hours at $95/hr with 0% tax, 4 parts at $40 each with 8.5% tax, and a $150 travel fee with 0% tax. Apply a 10% discount and set a fixed deposit of $100.”
Retail order summary with percent deposit
“Can you work out the invoice totals for an order with 12 units at $30 each taxed at 7%, and 3 units at $85 each taxed at 7%? I want to give a 5% discount on the subtotal and collect a 20% deposit upfront.”
Service business pre-payment breakdown
“I need to figure out what my customer owes upfront — the invoice has 1 design consultation at $500 with no tax, and 8 hours of implementation at $75/hr with 6% tax. No discount, but I need a 50% deposit.”
Technical details
Endpoint
POSThttps://www.tradepilotusa.com/api/agent-commerce/v1/services/invoice_totals_calculate/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need deterministic, server-side invoice arithmetic with per-line tax rates (not a flat blanket rate), an optional pre-tax discount, and flexible deposit handling (percent-of-total or fixed amount). Ideal for trade, field service, or contractor workflows where line items carry different tax rates. Prefer this over client-side math when you need an authoritative computed result to display or pass downstream without storing the invoice.
Side effects
- Missing required fields (quantity or rate on any line item) returns a validation error
- line_items array empty or exceeding 200 items is rejected
- discount_percent outside 0–100 range causes a validation failure
- deposit_value negative is rejected
- deposit_type provided without deposit_value or vice versa may cause incomplete calculation
- Non-numeric values in rate, quantity, or tax_percent fields will be rejected
