# setInvoiceToleranceConfig

## Overview

Upserts a supplier's invoice tolerance configuration for a company. The InvoiceToleranceConfig is unique per (company, supplier); this resolver creates the row on first save and patches it on subsequent saves, so callers have a single "set" mutation regardless of whether a config already exists. Each of the four tolerance fields (absolute/percentage × quantity/unit-price) is optional — an empty value is stored as null, meaning strict matching for that field. Percentage values are fractions (0.05 = 5%). The tolerances relax the quantity and unit-price variance checks that run during AP document registration (3-way match); a variance within tolerance no longer raises a SYSTEM payment hold. Tolerance values must be non-negative. Returns the InvoiceToleranceConfig ID.
