# Intelligent Invoice Tolerance Validation & Approval Routing

Checks invoice discrepancies against tolerance rules and auto-approves or escalates them.

**Core Domain:** Supply Chain Management

**Supported Digital Worker:** Supplier Invoicing Manager (SIM)

#### Overview

Evaluates supplier invoice discrepancies after upstream 2-way or 3-way matching has been completed. It calculates the total variance, retrieves the supplier's configured amount and percentage tolerances, and determines whether the invoice can be automatically approved or requires human review.

#### Business Challenge

AP departments manually assess invoice discrepancies against supplier and company tolerance policies before paying suppliers.

#### **How this skill fits into the workflow for:**

**Supplier Invoicing Manager (SIM)**

{% stepper %}
{% step %}
Performs PO matching
{% endstep %}

{% step %}
Retrieves supplier tolerance settings
{% endstep %}

{% step %}
Compares invoice totals against PO and receipt information
{% endstep %}

{% step %}
Evaluates allowed tolerances, supplier risk profile, invoice thresholds, and business approval policies
{% endstep %}
{% endstepper %}

#### Decision Logic / HITL

* Auto-approve when: matching is successful and variance is within tolerance
* Escalate when: tolerance exceeded, high-risk supplier, large invoice amount, or repeated discrepancy pattern

#### Business Value

* Touchless invoice processing
* Consistent tolerance enforcement
* Faster approvals
* Reduced AP exceptions
* Better compliance control

#### Key Capabilities

* Supplier tolerance retrieval
* Invoice variance calculation
* Amount & percentage tolerance validation
* Automatic invoice approval within configured tolerance
* HITL and authorization routing for out-of-tolerance discrepancies
* Tolerance retrieval failure handling
